Detentions for sewage treatment on the increase

Marine pollution has always been in the spotlight but now, even more attention is being paid to the impact of sewage on the environment. Strict regulations and an increasing focus on compliance is having a big effect on shipping.

A recent bulletin issued by UK P&I Club has highlighted the issue. It reveals that detentions due to sewage are on the rise at an alarming rate.

Detentions

The bulletin concerns recent data released by the Maritime and Port Authority of Singapore (MPA) which shows the extent of the problem. So far in 2019, the most common reason for the detention of their vessels was sewage-related.

The deficiencies – generally worded as ‘sewage treatment plant defective’ – could be down to a number of issues. These range from poor maintenance of equipment, inadequate checking of effluence or, in some cases, discharging raw sewage directly into the waters of the port.

Detentions for inadequate sewage treatment are a growing concern for ship operators. In 2018, sewage was also listed as the second most common detainable deficiency in the Tokyo MOU.

MARPOL Annex IV

The legislation that you need to comply with will depend on factors such as the vessel size and type, where it’s operating and when its sewage treatment equipment was installed.

Annex IV is a complex piece of legislation which focusses on the treatment of sewage and the discharge of sewage effluents. We’ve compiled a comprehensive free guide to help clarify all aspects of sewage effluent legislation which applies to commercial shipping vessels.

MARPOL Annex IV applies to ships on international voyages which are over 400 gross tonnage, or those that are less and certified to carry 15 passengers and crew. It contains detailed regulations about the onboard equipment needed to control sewage discharge, the reception facilities that must be provided at ports and terminals, and the requirements for survey and certification.

There are a number of guidelines within MARPOL Annex IV that are worth paying particular attention to in order to avoid detention:

Resolution MEPC.227(64)
This applies to sewage treatment plants installed after 1st January 2016 on ships that are operating outside the ‘special areas’ designated in MARPOL Annex IV (detailed in MEPC.200(62))

Resolution MEPC.159(55)
These are revised guidelines about implementing effluent standards and performance tests for sewage treatment. They apply to treatment plants installed between 1st January 2010 and 1st January 2016 on vessels that operate inside ‘special areas’.

Resolution MEPC.2(VI)
This contains recommendations for international effluent standards and provides more guidance for performance testing in sewage treatment plants. It applies to equipment installed before 1st January 2010 on ships operating in ‘special areas’.

Inspections

During an inspection, the vessel should be able to demonstrate that it meets all the operational requirements of MARPOL Annex IV when it comes to effluents and sewage treatment. The International Safety Management Code also requires crews to be familiar with sewage treatment systems and maintain up-to-date records.

If a defect is discovered, this must be reported to the appropriate authority at the earliest opportunity. Additionally, you can’t make any changes to the ship’s systems without authorisation from the Flag Administration after an inspection has been conducted.

Essentially, you need to make sure that your sewage treatment processes are always compliant or you risk detention.

A Simple Solution

The amount of legislation can be overwhelming – especially as it’s frequently updated and is likely to get even more stringent in the future. Our new Sewage Water Test Kit offers an easy way to make sure your sewage treatment processes meet the regulations.

It provides you with everything you need to carry out regular testing and doesn’t require any formal training. Everything comes in one kit and the test procedures don’t use any complicated equipment – they’re quick and easy and can be performed by anyone. Its design is based on recommendations from the Department of the Environment and the Water Research Centre so you get only the most vital components that make sure you’re compliant.

Carrying out regular tests of your vessel’s sewage will enable you to identify issues much earlier and correct them with the minimum of difficulty. This will save time and money, and increase your productivity.

Don’t risk detention. Make sure your sewage processing is compliant.

10 reasons why you need to be connected at sea

Reliable broadband at sea can have a dramatic effect on your running costs and save you money in a variety of different ways. Here we look at 10 reasons why operators need to stay connected…

  1. Efficiency

Being connected means data collection and reporting systems are able to operate in real time. The Internet of Things (IoT) enable sensors on mechanical and digital devices to transfer information over a network without human interaction. This can provide you with precise details about fuel consumption, operating conditions, regulatory compliance and many other performance indicators which can either be managed onboard or transmitted instantly to shore.

  1. Crew welfare

Today’s crews are made up of a multitude of different nationalities working longer hours with much faster turnarounds in ports. The average person touches their smart phone 2,617 times a day so being in an isolated environment without the ability to connect with family and friends can have a debilitating effect on a seafarer’s morale. This is particularly important as crews get younger – millennials’ have grown up in the digital age where connectivity is taken for granted.

A good internet service will allow people to use their own devices in the privacy of their cabins, accessing news services in their native language, internet banking, instant messaging and a variety of sport and entertainment options.

  1. Safety

As well as keeping close contact with onshore support and guidance, you’ll also be able to receive live reports of hazardous situations and get instant access to medical specialists if one of your crew falls ill or is injured.

Additionally, the IoT enables operators to easily monitor potentially dangerous materials and maintain safety equipment by using live cameras and sensors. For example, if a lifebuoy or raft is deployed and this information is automatically transmitted back to shore as soon as it hits the water, then rescue operations can begin much quicker.

  1. Lower Insurance Premiums

The data you receive from onboard sensors can be used to demonstrate your safety record to insurance companies. This can result in significant savings for ship operators.

  1. Less down-time

Data collection and constant monitoring of equipment is much more cost-effective than being suddenly surprised by an unexpected problem which could result in lengthy delays.

If your ship has good connectivity, it will also allow remote access. This means that experts can access computers, software and networks from shore, cutting down on the need for onboard visits when you’re in port.  System maintenance, upgrades and troubleshooting can all be done by remote administration without interrupting your day-to-day operations.

  1. Keep up to date

Updates to navigational charts, weather forecasts and operational procedures can all be done effortlessly with a good internet connection at sea. Additionally, media services like the one offered by KVH will allow shipowners to send video messages easily from headquarters to vessels in the fleet.

The mini-VSAT Broadband  provides exceptional call quality with perfect clarity as well as supporting Wi-Fi calling between cell phones. It’s able to do this by automatic fast switching between its global network using redundant beams for seamless and completely reliable communications wherever you are in the world.

  1. Training

The shipping industry is constantly developing and improving so modernising working practices is an ongoing challenge. New equipment, new processes, new techniques – crews always need to be operating at maximum efficiency. Training can therefore be an issue, taking up valuable time.

Access to learning and professional development is much simpler when there’s a strong internet connection at sea. It allows real-time chat between the shore and the vessel and downloading content isn’t a problem – training materials and large files will be easily accessible with a high-speed data channel.

  1. Attract and retain good crew

As all modern companies know, a lower turnover of staff is more cost-effective and business savvy. You don’t spend as much money on recruitment costs or training which can soon stack up as new ships enter fleets and workforces become older.

Research shows that full access to the internet is an important consideration when seafarers are deciding which vessel to work on – 75% say that this influences their choice. In terms of just how important, 92% of both officers and regular crew said that it has a ‘strong or very strong influence on who they worked for’.

  1. Stay competitive

Operators need to keep up with advances in technology in order to future proof their vessels. They can’t afford to ignore developments in efficiency, cost-effective practices and data collection as their rivals will undoubtedly be using them to give them the edge in their operations.

The maritime industry now understands the important role technology plays with 69% of seafarers seeing big data and analytics as a valuable part of their jobs in the next five years. 75% also see predictive maintenance as an opportunity rather than a threat. This shows just how vital being connected is in today’s environment – operators need to take care not to be left behind.

  1. It can be easy

Getting reliable broadband onboard your vessels is no longer a complicated and expensive process. With the mini-VSAT Broadband package, you can easily monitor bandwidth use, charge seafarers for what they use, manage traffic settings and maintain cyber security.

It’s powered by a high-speed worldwide network and provides expanded global coverage. The plan is simple and flexible with a single monthly subscription and no long-term contract so there’s no commitment – your airtime options can be adapted to fit the needs of your particular operation. If you need to cancel at any point, you won’t be penalised.

Instead of using a whole rack of equipment, this one simple box which can be installed free in selected international ports. There’s also a global support programme with up to five years warranty on parts and labour.

Make sure you’re reducing costs and improving efficiency by using a safe, reliable internet connection at sea.

NO commitment, NO penalties, NO hassle.

What is Reactive Gas?

Carrying effective gas detection equipment – and making sure that equipment is performing accurately – is an essential and potentially life-saving element of shipping. Obviously, the safety of vessels and crews is of paramount importance but, despite the best efforts of the IMO, deaths are still happening at an alarming rate.

Reactive gases in particular present lots of additional dangers. They can also provide extra headaches for operators when it comes to storage and supply.

What are they?

Essentially, reactive gases are much more chemically active than other, more commonly used gases. Their properties change in different atmospheres and they even react with the materials that they come into contact with, especially plastics and moist surfaces.

For this reason, they’re often called ‘sticky’ gases and they present many extra issues when they’re used for gas detection and calibration.

Gas detection

Their higher chemical activity means that they are more easily absorbed by the exposed areas of gas detectors like the housings, adapters and tubing. This depletes the amount available to test in a gas sample so you need to take special care when monitoring.

Using compatible materials and appropriate calibration techniques is therefore essential. Otherwise, the response time will be increased and your readings will be dangerously low.

Storage

Because reactive gases are so chemically active, they even react with the containers that are used to store them. Over time, they will be gradually absorbed by the walls of the cylinders.

To minimise these reactions, reactive gas mixtures come in aluminium canisters – generally available in either 34 or 58 litres – but they still have a limited lifespan. That’s why all cylinders have a shelf life that’s clearly labelled on the outside. Expired calibration gas will no longer provide accurate readings and will be potentially dangerous.

Lifespan

Because of the instability and impurity of the gases used and the relatively poor quality of cylinders within the industry, most calibration gases have a short shelf-life of just 6-12 months. This leads to many problems when it comes to supply.

Gases need to be replaced regularly – regardless of how much remains in the cylinder. In addition to the wastage of gas that’s gone out of date, multiple re-stocking deliveries will need to be arranged for each ship incurring freight costs, dangerous goods charges and customs’/agent’s fees.

Organising multiple deliveries and arranging schedules takes up valuable time. This is further complicated when using several suppliers as quality control can be an issue – different providers will all need to meet the same standards. Organising a reliable supply of calibration gas for a global fleet can prove a troublesome and time consuming process.

Martek’s cylinders

FastCalGas has the highest gas production standards of any calibration gas on the market. We use advanced materials and a mass spectrometer to analyse and verify the quality of every cylinder – in 30,000 deliveries, only two defects have ever been reported. This is a quality yield of over 99.993%.

Because of this, we can offer a 27-month shelf life on all reactive mixtures – a world first in the industry. This makes ordering far less complicated as you can order large stocks up to two years in advance without worrying about co-ordinating supplies that have short expiry dates.

Our cylinders are also recyclable which means that you can sell empties on to recycling companies for roughly $2 each instead of throwing them away. They just need to be prepared first.

The most important part of this preparation is to make sure they’re completely empty of any reactive gas. This will involve drilling a hole in the cylinder – some recycling companies may also require you to cut them in half. The valve also needs to be removed or rendered unusable to prove that the cylinder is no longer pressurised. This can be done quickly and easily with one of the tools that are compatible with all our canisters.

After this, cylinders will no longer classified as dangerous goods and can be recycled as scrap.

The Procurement Process

Our calibration gas inventory management service will enable you to save even more time and money by taking control of your ordering and supply process.

Martek’s service is designed to cut down on carriage and agents’ charges as well as the hidden costs that come from the time spent on administration. It simplifies the process into one order, two years’ supply and one delivery.

We review your usage of calibration gas to determine your requirements and run on-going checks with vessels, contacting each ship to arrange re-stocking after twenty-one months. Simply pass on the inventory of gas detectors on board your fleet or let us contact the ships directly to get the information and we take care of the rest.

You can purchase calibration gas quickly and easily online from anywhere in the world. Our lean order processing and extensive global supply chain means that we have a 4 hour turnaround on quotes and 98% of our orders are shipped within 24 hours.

Stop the hassle and start gaining competitive advantage.

Marine Sewage Water: The Legislation

The pathogenic organisms, viruses and bacteria present in sewage can cause numerous diseases and infections in humans – not just from direct contact but indirectly from eating the fish that filtrate seawater and retain dangerous particles.

Marine sewage water can also have a devastating effect on sea life as sewage uses up valuable oxygen in the water as it disintegrates. This results in the suffocation of fish, coral, seaweed and other micro-organisms that are essential to the eco-system, particularly in shallow seas and coastal areas.

The problem has long been recognised and reducing marine pollution from sewage was the first ever environmental initiative. Regulations initially came into force over a hundred years ago and since then they have been constantly updated and amended to reflect the changing face of modern shipping.

MARPOL Annex IV

MARPOL Annex IV applies to ships on international voyages which are over 400 gross tonnage, or those that are less and certified to carry 15 passengers and crew. It contains detailed regulations about the onboard equipment needed to control sewage discharge, the reception facilities that must be provided at ports and terminals, and the requirements for survey and certification.

If your vessel is equipped with an approved sewage treatment plant, an approved sewage comminuting and disinfecting system, or a sewage holding tank then you can discharge sewage at a distance of three nautical miles from the nearest land. However, the speed and rate of discharge must still be approved to meet the requirements set out in MEPC.157(55).

In addition to this, there are also designated ‘Special Areas’ (detailed in MEPC.200(62)) that may require further tests depending on the type of your vessel.

ISPCC

Vessels visiting countries that have ratified to MARPOL Annex IV need a relevant ISPCC – an International Sewage Pollution Prevention Certificate. This is issued after a successful inspection and is valid for five years. If you don’t have an ISPCC or your sewage treatment facilities fail the inspection, your ship could end up facing detention.

What you need to do

You have to make sure that your sewage treatment plant is installed in a way that enables effluent test samples to be collected. This sampling should be carried out in accordance with the regulations.

A minimum of forty samples should be collected to allow for statistical analysis of the data. The frequency of testing should take into account the length of time the effluent is sitting in the treatment plant and the test period should take a minimum of 10 days so that the discharge can enter a stabilisation period. The samples should also reflect normal conditions – the type of system, the number of people on-board and the operational processes involved.

Simple Solution

Pollution from marine sewage water has always been in the spotlight so new regulations are continually being introduced to try and control it. The legislation that applies to you will depend on factors such as your vessel size and type, where you’re operating and when your sewage treatment equipment was installed.

The amount of legislation can be overwhelming so our new Sewage Water Test Kit offers an easy way to make sure you’re always compliant. We’ve also created a free ebook to help clarify the key elements that you need to know.

Your ebook will cover:

  • Terminology & Definitions
  • Why Test Sewage Effluents
  • Effluent Testing Legislation
  • Quick Guide To The Required Testing
  • Sewage Effluent Test Kits
  • The Martek Sewage Effluent Test Kit

The procedures are quick and simple to perform and don’t use complicated equipment so they’re suitable for everyone to use. The tests are based on those recommended by the Department of the Environment and the Water Research Centre and provide you with only the most vital components that will allow you to carry out essential quality control checks.

This will save time and money and increase your productivity – if you carry out regular tests of your vessel’s sewage, you can identify issues much earlier and correct them with the minimum of difficulty. This is much more efficient than waiting until a problem develops as repairing faults or being detained will have a major impact on your operations.

Why your hatch testing needs to be accurate

Over 40% of all P&I claims are due to damaged cargo. Water ingress from hatch covers makes up the majority of these claims – even small amounts of water can cause extensive damage.

Every year, the North of England P&I club has three to four claims of between $500,000 and $1,000,000 for water-damaged cargoes resulting from hatch cover defects. Tony Baker, head of the club’s risk management department said: ‘The cost of preventing these losses can usually be measured in a few thousand dollars or less. Often all that is necessary is the replacement of some defective rubber seals, some minor repairs to steelwork or sometimes just cleaning down a coaming.’

Hatch covers are the responsibility of the ship’s owners and operators, so you need to pay close attention to them to make sure that your cargo is protected. Regular checking and maintenance is much cheaper and more effective than major repairs or incidents caused by neglect.

Testing Methods

Water hose testing and chalk testing are the two most common methods for checking hatch covers. While water hose testing can detect a leak, it can’t accurately pinpoint exactly where the problem’s coming from – and it won’t work in sub-zero conditions either. There’s also the added complication of making sure any cargo contained in the hold is adequately protected from the water used in the test.

Chalk testing doesn’t have some of these limitations but it isn’t considered to be a leak detection test as it only gives an indication of poor compression and possible leaks. It’s not effective in identifying weathertight integrity so it might not be acceptable to many external surveyors.

Ultrasonic Testing

This is the most accurate way to ensure your hatches are functioning correctly. A transmitter in the cargo hold emits ultrasound waves which are then picked up by a receiver outside the closed hatch. Unlike water hose and chalk tests, ultrasonic testing indicates when you have the required compression and gives you the precise location of any leakages. In addition to this, the equipment is easy to store and use, only needs one operator and doesn’t rely on the cargo hold being emptied.

However, just like any piece of technical equipment, there are some extra factors that need to be considered to ensure that your ultrasonic testing device is operating effectively.

Calibration

Ship operators and P&I clubs need to be sure that the equipment used for testing is behaving consistently every time, so readings taken by devices that are not calibrated are open to being rendered invalid. This could jeopardise potential insurance claims as, in a court of law, any results from equipment not shown to be in calibration could be disputed and disallowed.

Calibrating Hatchtite

Hatchtites are made to a very exacting standard so that their performance will not deteriorate quickly over time. Each device will give exactly the same correct and consistent readings, regardless of the specific device that’s being used. This is particularly important when comparing results that have been logged over a long period.

If properly cared for, a Hatchtite will also last for five years before they require re-calibration – the longest time period for an ultrasonic hatch testing device in the industry. After five years, it should be returned to make sure that:

– All components are clean and working in good order

– Any components that are approaching the end of their lives can be replaced or repaired

– The transmitter and receiver are tested to make sure the decibel readings are accurate

– Any relevant updates are implemented.

HATCHTITE Calibration

Calibrating your Hatchtite will ensure that you’ll always be able to test your hatches efficiently and reduce the risk of losing your cargo.

A Quick Guide to Sewage Effluent Testing

Sewage Effluent Testing

Sewage pollution from shipping has always been in the spotlight. Without comprehensive checks on Sewage Effluent, it can have catastrophic effects on the environment and the wellbeing of both human and aquatic life. To combat this, Sewage Effluent regulations have been in effect for over a hundred years and they will continue to get more and more stringent in the future as public awareness grows.

However, some of the terminology and procedures involved with sewage effluent testing can seem impenetrable to anyone not familiar with the inside of a laboratory. To help with this we’ve put together a quick guide to help with the key elements that you need to know.

We’ve also compiled an ebook, ‘A Guide To Marine Sewage Effluent Testing’ which explores the topic, regulations and solutions in more detail. If you would like to claim a free copy please fill in this form

PV

The Permanganate Value (PV) helps to determine the oxygen requirement of sewage and sewage effluent before it’s discharged. The waste can then be classified to make sure it’s within the necessary limits.

The PV test is designed to show the oxidation of organic material that occurs in natural waters by using potassium permanganate under acidic conditions to accelerate the process. The measurement is usually represented as the quantity of oxygen consumed per litre of water: mg/L O2 or ppm O2.

COD, BOD and TOC

Chemical Oxygen Demand (COD) measures the amount of dissolved oxygen needed to break down the organic material in a water sample.

The Biological Oxygen Demand (BOD) is similar – both measure the presence of compounds – but the BOD value is more detailed as it provides a value for the oxygen needed specifically by bacteria. The higher the BOD value, the larger the amount of food available for oxygen-consuming organisms.

TOC stands for Total Organic Carbon and measures the amount of decaying matter in water. It has been used to analyse water quality and sewage effluent since the early 1970s.

You can estimate a sample’s COD, BOD and TOC values by converting the results of the PV test. Although the results are not definitive, it’s a simplified and low-cost way of carrying out the most essential quality control checks.

pH

Chemical and biological reactions in sewage greatly depend on the amount of acid or alkaline present – the pH. Therefore, regular checks on the pH in your sewage effluent are essential.

These tests are carried out with a Universal test tablet and a printed colour strip that covers a pH range between four and ten. The expected level for your sewage effluents should fall between six and eight.

Free, Combined and Total Chlorine

Chlorine is useful for disinfection as it kills bacteria and viruses – it’s been used in water treatment since the early 1900s. However, it can have a harmful effect on the environment and marine life when released in wastewater.

Free Chlorine is residual chlorine contained in water either as dissolved gas, acid or ions. Combined Chlorine is the concentration of chlorine that has already gone through a chemical reaction – usually with ammonia or organic materials. The Total Chlorine is made up of both of these measurements together.

Bacteria Plate Test
As bacteria aren’t generally visible to the naked eye, a plate test is a way to estimate how many are present in a water sample.

It uses a plate containing a nutrient which allows bacteria to colonise and grow. These will show as a red colour which can then be counted. By using a specific measured amount as a sample, you can then scale up the results to infer the overall content of the effluent.

E.Coli

Escherichia coli (E. coli) is a type of bacteria found in the stomachs of humans and other warm-blooded animals. There are many different strains – most of which are harmless – but some can cause diarrhoea, abdominal pain, fever and vomiting. It can also be fatal for people with weakened immune systems. Checking for E.Coli in sewage effluent is therefore vital.

Testing works in a similar way to the bacterial plate. You take a sample, add specially designed chemicals and then wait for the results which will be either positive or negative. If they’re positive, you should super-chlorinate your water supply and seek further guidance.

Turbidity and Suspended Solids

The turbidity of liquid means how clear it is. Individual particles of suspended solids will cause water to lose its transparency and become murky in a similar way to smoke in the air.

The suspended solids may not be visible to the naked eye so testing the turbidity will give a measure of their content. The test will also keep you informed about the day to day variations in the quality of your wastewater and sewage effluent.

The Royal Commission Standards for Effluents recommend that the suspended solids content of sewage effluent should not be more than 30 mg/l.

Temperature

Sewage Effluent discharge should always be as close as possible to ambient temperatures as some biological processes are dependent on heat. Chemical reactions – as well as marine life – are very sensitive to even minor variations in temperature.

Checking the temperature of your wastewater is particularly important when it comes to industrial processes as well as the use of hot water in showers, dishwashers, washing machines and other regular domestic appliances.

Sewage Test Kit

If you carry out regular tests of your vessel’s sewage, you can identify issues much earlier and correct them with the minimum of difficulty. This is much more efficient than waiting until a problem develops as repairing faults could have a major impact on your operations.

The equipment in our onboard Sewage Effluent Kit makes sure you meet the regulations in the most simple and effective way possible – the tests are based on those recommended by the Department of the Environment and the Water Research Centre.

10 reasons why you should be testing your sewage water

Marine pollution from sewage has always been one of the world’s most prominent ecological problems – in fact, reducing it was the first ever environmental initiative. New technology and regulations have been developing for over a century and will continue to do so in the future.

Here are ten reasons why testing sewage on your vessels is so important and how the new Sewage Effluent Testing Kit from Martek can help.

1.) Sewage water testing helps avoid health hazards

The pathogenic organisms, viruses and bacteria present in sewage can cause salmonella and hepatitis A and E as well as numerous gastrointestinal diseases and infections. Indirect contact is also harmful as many marine creatures filtrate seawater, retaining the dangerous particles which may then be passed on to those who eat them.

2.) Sewage water testing helps limit marine pollution

As well as the deeply unpleasant visual impact, sewage is also extremely damaging to sea-life – particularly in shallow seas and coastal areas. Because it uses up valuable oxygen in the water as it disintegrates, it can result in the suffocation of fish, coral, seaweed and micro-organisms essential to the eco-system

3.) Sewage effluent testing reduces downtime

If you carry out regular tests of your vessel’s sewage, you can identify issues much earlier and correct them with the minimum of difficulty. This is much more efficient than waiting until a problem develops as this may result in your system being out of action while it’s repaired.

4.) Sewage effluent testing reduces costs

Downtime means your vessel isn’t operating at maximum profitability. Repairing faults with your sewage system could have a major impact on your operations, something that can be easily avoided with regular testing.

5.) Sewage water testing ensures you’re compliant

More and more attention is being paid to sewage and its effects. This has resulted in more stringent quality standards and regulations – and these are likely to get even more comprehensive soon. A good sewage testing kit will keep you compliant with current legislation as well as helping to make sure you’re prepared for future changes.

6.) Testing your sewage is easy

The Sewage Effluent Kit from Martek provides a means of checking quality by using simplified methods of testing. To reduce wastage and keep your costs at a minimum, the kit contains only the most vital components that will allow you to carry out essential quality control checks.

7.) It’s quick to carry out a sewage water test

The kit provides simple tests for Permanganate Value, Ph, Suspended Solids, Probable BOC (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand) and TOC (Total Organic Carbon). The tests provide measurements rapidly to keep your time and your costs down.

8.) Our Sewage Effluent Kit adds on to your existing Martek equipment

If you’re already using DrinkSafe for your potable water, the sewage testing kit fits alongside it for a complete water testing solution – the first and only combined package on the market.

How to Recycle Your Gas Cylinders

In order to meet legal and industry requirements, and ensure safety in the workplace, it’s critical to that your gas-detection devices are functioning correctly. These gas detectors serve a vital role by monitoring environmental conditions and alerting us to potential leaks or hazardous conditions. Conducting frequent calibration tests means that you’ll be going through a lot of span gas—it also means you’ll be left with a lot of empty gas cylinders.

10 Reasons Why Access to Drinking Water is so Vital

We couldn’t survive without water. Around 60% of our body is made up of it and it’s essential to the processes that keep us functioning ¬– dehydration can be a contributing factor in life-threatening problems with your heart, lungs, kidneys and bladder.

However, we’re constantly losing water in a variety of ways – especially on board ship where the effects are increased further – so it’s crucial that we replace it to keep healthy. This isn’t always easy when you’re at sea and access to a supply of safe, potable drinking water can be complicated.

Here are 10 reasons why staying hydrated is so important:

1. Drink water for strength and endurance

Your muscles can’t contract and expand efficiently without water which will lead to a reduction in your physical abilities and a longer recovery time after exercise. The water you get rid of when you sweat also means that you’re losing valuable nutrients.

2. Drink water to think and concentrate

As well as other sensitive tissues, water cushions your brain and spinal cord. Without it, your brain cells shrink and the production of neurotransmitters is interrupted so your ability to focus on even the simplest of tasks will be affected.

3. Drink water to stay sharp

Failure to hydrate properly leads to fatigue and tiredness. Water is a much more effective drink than sugary energy drinks which might give you a sudden boost but will lead to an energy crash later.

4. Drink water to breathe

If you’re dehydrated, your body will restrict your airways to try and minimise water loss. This effects your ability to breathe and increases the impact of asthma, allergies, colds and viruses.

5. Drink water to stay cool

When your body heats up, the water that’s stored in the layers of your skin comes to the surface as sweat and cools you down. This water needs replacing to prevent heat exhaustion in a hot environment or during physical activity.

6. Drink water as part of a healthy diet

While water is no substitution for food, it can help with your eating habits – especially if you have it instead of sweetened fizzy drinks and juices. Drinking water before a meal will help your stomach to fill up and you’ll need less food to be able to function properly.

7. Drink water for your joints

The cartilage around your joints and spine allows bones to move freely against each other – its spongy texture is made up of over 80% water and prevents grating and rubbing. Without enough water, cartilage loses some of its shock-absorber effect so there’s more friction. This results in your joints aching and becoming painful.

8. Drink water for your circulation

Our blood is made up of over 90% water and if this concentration falls, it becomes thicker. This makes it harder for the heart to pump it around your body leading to an increase in blood pressure.

9. Drink water for your digestion

Your stomach and bowels need water to function properly and, if you aren’t getting enough, you run the risk of constipation, heartburn and stomach ulcers.

10. Drink water for your body waste

Saliva, tears and mucus all depend on having sufficient water and it flushes waste from your system when you go to the toilet. If you can’t maintain and regulate your body fluids, it will lead to problems with your kidneys in the long term.

Access to drinking water on board ship is not easy. With Drinksafe, you can make sure that your crews always have a good supply. As well as guaranteed compliance with water testing regulations, it’s one of the easiest to use and most cost-effective kits on the market.

That’s why the world’s largest shipping companies trust Drinksafe to take care of the well-being of their crew and passengers.

There have been gas detectors for as long as people have been aware of the harmful effects of gases in confined spaces. In the early days of mining, well before the development of electronic sensors, canaries were used.
They were taken underground in cages and if they stopped singing or died, then the miners would be alerted.

We’ve come a long way since the 19th and early 20th centuries. Now gas detection methods are much more precise – and much less harmful to animals.

How a modern gas detector works

Gas detectors use a sensor to measure the concentration of particular gases in the atmosphere. The sensor serves as a reference point and scale, producing a measurable electric current when a chemical reaction caused by a specific gas occurs. The sensor will monitor these currents and alarm the user when the presence of gas approaches an amount that is hazardous.

Early instruments were made to detect just one gas but now they can measure several at once – most commonly, oxygen (O2), flammable gases or vapours (LEL), hydrogen sulphide (H2S) and carbon monoxide (CO). These are the gases that a 4-gas detector monitors, the minimum requirements set out by SOLAS Regulation XI/1-7.

The sensor

Most portable gas detectors use a pellistor/catalytic bead LEL sensor. To function accurately, it requires a minimum of 10% oxygen in the environment to avoid the build-up of tar and unburned fuel on the activated ring.

Theoretically, the sensor can last up to four years but it is very sensitive and can easily break if the monitor is knocked or dropped.

Most sensors will be reaching the end of their life by the time they are three years old and will need replacing. This can be a costly process that will leave the detector out of action, so you also need extra instruments to make sure you’re covered while the repair work is being carried out. Other components like backlight screens and audio alerts will begin to develop faults too so it’s important to keep detectors well-maintained.

Calibration

Pellistor sensors can be poisoned by many things, including the gases they’re detecting.

Contaminated sensors may not register dangerous gas levels and will become gradually slower and more unresponsive over time. Their performance depends on thorough testing using calibration and bump-testing to make sure they’re always measuring the correct amount of gas to keep seafarers and vessels safe.

Infrared sensors

These don’t require oxygen so will work in completely inert atmospheres. This makes them ideal for confined space detection and taking samples from tanks where a lack of oxygen is an issue. They’re also immune to sensor poisoning so there’s no need for calibration to ensure the gas detector is functioning correctly.

A traditional pellistor sensor uses a heated aluminium coil that drains a large amount of power. However, gas detectors that use infrared sensors are much more energy efficient with batteries that won’t require charging as frequently.

MGC Simple+

The cutting-edge infrared technology in the MGC Simple+ means its battery lasts for three years without charging – a world first for a portable gas detector.

It doesn’t require calibration (although it can be easily set-up to do this to meet the specifications of a risk assessments or safe systems of work) and is rated IP68 so is protected from even the finest dust and can be submerged in water for 30 minutes at a depth of 1.5m.

MGC Simple+ also comes with a full warranty for three years so you’ll never incur extra repair costs.

At the end of those three years, you simply replace the detector – a much cheaper option than spending money maintaining an old instrument. Buying a new detector means that you’ll also have a new three-year warranty, the instrument will always be covered.

The MGC Simple+ is the future of gas detection – the world’s first ‘NO calibration’ portable multi-gas detector.

NO calibration. NO charging. NO cost.
