Water Condition Monitoring

Increase Safety on board.

Minimize risk to the crew.


Offshore facilities and vessels have a variety of systems that require monitoring for optimal performance, compliance with current or future legislation, and minimizing risks to the crew or the health and safety of the visitor on board. With that in mind, an exciting new line of CMT Aquamarine Kits has been developed to support and fulfill the above requirements.

Non-conformity inspections or failures may result in vessel detention.

Marine boiler and cooling water test kits

This line of CMT kits will allow the ship’s engineer to monitor scale and inhibitor levels accurately. Regular testing will let quick corrective actions take place, maintaining optimal operating conditions, minimizing downtime, and reducing costs.

Potable water test kits

CMT Marine Hygiene kits were developed to offer platforms and vessels the complete solution for monitoring their drinking water systems. Adequate control schemes with adequate testing and monitoring will help to comply with the current IHR (2005), ILO 178 (2009), and ILO MLC (2006). These test kits provide real-time analysis and simple-to-perform tests.

Sewage Water Test Kits​

Ultimately, the CMT Wastewater Kit will help with MARPOL Annex IV compliance, especially for initial/renewal inspections and spot checks for certification. The sewage effluent testing kit will provide simple and accurate testing for BOD, chlorine (free), COD, coliform bacteria, pH and total suspended solids. Regular testing will allow quick corrective action to take place if necessary, helping to maintain optimal operating conditions, minimal downtime and reducing costs.

We keep top notch materials

The highest quality materials provide the highest quality products.


International regulations regarding the Potable Water Quality Monitoring and Control were driven by the World Health Organization (WHO) via its International Health Regulations (IHR). And soon enough adapted for on-board potable water, as part of the overall Ship Sanitation Certificate. MLC 2006 does apply to all seagoing vessels and is in force since the 20th August 2013. Monitoring and control compliance procedures are laid out in the Guide for Ship Sanitation detailing:

> The systems that require monitoring

> The method and frequency

> The record keeping requirements

Simple regular assessment and testing of the potable water system for microbiological activity, biocide (disinfection control) and implementing a correct control scheme (i.e. temperature monitoring), will ultimately reduce the risk of a disease and save lives.

The CMT Potable Water Test Kit enables ships staff to monitor the quality of the drinking water on board the ship by providing tests for important operational control parameters and verification tests for bacteria that can be of risk to human health. The range of tests can be used on the ship either as a standalone control solution or as a supplement to laboratory analysis, dependant on flag state guidelines.

CMT is offering 2 different versions of the Potable Water Test Kit. The standard version includes tests for Aerobic Bacteria as well as E Coli. The Full Potable Water Test Kit extends the standard test kit with tests for Enterococci and Pseudomonas bacteria. Both Test Kits include a Digital Incubator to ensure consistent results with same conditions on every test.

To test the discharge of Sewage treatment plants CMT offers a quick and easy drop test for testing the free chlorine content

ISPPC (International Sewage Pollution Prevention Certificate) are issued upon successful inspection and are valid for 5 years.

For renewal and random inspections, maintaining the system operating requirements in line with the effluent standards will be required. With this in mind, the CMT Marine Sewage Effluent Test Kit will provide simple and accurate testing. 

Nowadays tests in the market are complicated and comprehensively. The Chief-Engineers almost need to have a chemist-degree in order to understand and execute the time consuming tests. The CMT Sewage Effluent Test Kits are simple and very user-friendly. To test the discharge of Sewage treatment plants CMT offers a quick and easy drop test for testing the free chlorine content.

CMT offers three different versions of the Sewage Effluent Test Kits to better suit your needs.

> Sewage Effluent Test Kit 1 complies with MEPC 2(VI) Commission before 2010.

> Sewage Effluent Test Kit 3 complies with MEPC 159(55) & 227(64) for all passenger ships.

Regular testing will allow rapid corrective action to take place if required, helping to maintain optimum operating conditions, minimum down-time and reducing costs. Ultimately the Marine Sewage Water Test Kits will aid compliance with MARPOL Annex IV.

Ballast Water Test Kit

As everyone in the industry knows, ballast water exchange is an important process, but it’s one which involves several complex processes. There are guidelines which need to be followed in order to ensure the water is as safe and hygienic as it can possibly be.

The presence of any harmful bacteria, viruses and invasive species on a ship can have catastrophic effects, so our highly developed ballast water test kits are vital. Easy to use and reliably accurate, the kit enables user companies to remain compliant with current and future legislation and guidelines.

Engine cooling systems contain carefully blended additives that prevent scale deposits and corrosion of engine waterways. It is very important that the concentration of the additive is maintained at the correct level for optimum protection.

Although coolants are formulated to help prevent these problems from occuring, regular coolant testing and routine maintenance can help you achieve maximum system efficiency and save you time and money in less downtime, fewer repairs and determining proper drain intervals.

Marine Boiler and Cooling water kits will provide simple and accurate testing.

A boiler water system supplies steam for various processes such as pumping, heating, cooling, cleaning and hot water for accommodation.

Condensate is steam that has been returned to its liquid state. Steam, which is manufactured in the boiler, is used for various shipboard processes. Control of the condensate system is critical to the overall operation of the boiler. If the condensate system is not protected, corrosion will occur. Corrosion eats away at the metal in the pipes and equipment in the system. This can cause leaks in process equipment that can result in a process shutdown and expensive system repairs.

CMT test kits are very simple to use and will enable the ship’s engineer to monitor scale and inhibitor levels accurately. Regular testing will allow rapid corrective action to take place, maintaining optimum operating conditions, minimise down time and reduce costs.

CMTs new Portable Incubator brings lab like conditions to the field of onsite testing of bacterial contamination.
To create reliable and repeatable incubation conditions when in the field has been a problem in the past because small and portable but on the other hand reliable and temperature stable incubators were not available.

A bacteriological analysis demands an incubator to create repeatable results.
CMT’s Digital Incubator offers a reliable, temperature stable environment for the incubation of bacteriological samples and that while being portable and affordable.

The reliability of an automatic fire sprinkler is very important.
To prevent malfunction during an emergency the water inside of the system needs to be monitored to control corrosion and other hazards.

The IMO has issued revised guidelines (contained in circular MSC.1/CIRC. 1516) for in-service testing of automatic sprinkler and automatic mist systems.
The amended guidelines advise shipowners, operators and system manufacturers to actively monitor and assess the effectiveness of automatic sprinkler and automatic mist systems on a planned periodical basis. Water quality testing should be performed on a quarterly basis and results recorded.

Corrosion can cause major catastrophic problems with these systems, potentially causing system failure and leakage (pin-hole size leaks). We have included within the test kit testing for pH, conductivity and testing microbiological levels (total count of bacteria & sulphate producing bacteria).

Salt water ingress normally occurs when the system has been used (fresh water) and once depleted is normally by-passed directly using sea water. If this occurs the system is flushed through with fresh water. A chloride test is provided to ensure the sea water is not present which can cause corrosion problems.

Any part of the system may be subjected to freezing temperatures in service. Anti-freeze (mono-ethylene & mono-propylene glycol) is used as standard to protect these systems from freezing. A glycol refractometer is supplied to ensure the systems are being maintained at the correct freeze point or percentage product

It offers fire safety professionals real time analysis so that the systems being tested are managed and calibrated correctly.

Application and Use:
It is suitable for testing to the following International Produced Foam Test Standards:
NFPA 11 2002 (paragraphs 10.6.2 and 3)BS5306
It is also suitable for use with AFFF, Protein and AR Foams.
Firefighting foam induction systems require regular performance testing and often as a result recalibration.
The Produced Foam Test Kit enables systems to be easily calibrated, without the need to send samples

Both IMO and EU policies require ship operators to reduce the sulphur emissions of their ship operations. Vessels operating in a Sulphur Emission Control
Area (SECA) need to use either low sulphur distillate fuels or have an approved exhaust gas treatment system installed onboard to capture sulphur

For those ship owners and operators who have opted for the exhaust gas treatment option, the installation of wet scrubbers is becoming an increasing trend.
Wet scrubbers can operate in three modes, open loop, closed loop and hybrid mode which is a combination of both open and closed loop.

When vessels are operating in SECAs, closed loop scrubbing is required. In order to maintain alkaline levels in the scrubbing water, and as either fresh or sea
water pH range can be 6.5 – 8.5, for the effective scrubbing sodium hydroxide (NaOH) in a 50% solution is commonly used.
This product is usually bunkered onboard via the vessel’s dedicated bunker lines via road tanker or by delivery in drums and IBC’s.
The determination of the % of caustic solution is critical for ship operators as dosing rates and system set up is setup according to the specific % of caustic

Problem resulting from off-spec caustic are:

> A lower % caustic solution will lead to increased consumption and costs.

> A lower % caustic solution may affect the scrubbing performance and thus lead to the vessel failing to remain within its emissions requirements.

This kit has been developed to simply and quickly allow the crew to sample and analyse the caustic soda during bunkering in order to validate the % solution supplied matches the supply specification and if not to adjust system dosing accordingly or reject delivery.

Cutting fluids are required in metal machining to improve tool life, reduce work piece thermal deformation, enhance surface finish and to flush chips from the cutting zone. These fluids degrade with time due to bacterial growth and contamination with tramp oil. Testing is not just essential, it is required!

Health risks exist for lathe operators by both fluid contact (dermatitis) and breathing of the mist/vapour (asthma, extrinsic allergic alveolitis and other breathing problems). Biocidal additives improve the life of the fluid and reduce the hazard to health.

Ongoing monitoring, inspection and maintenance is required in UK as part of an employers obligation under Section 2 of the Health and Safety at Work Act 1974. Similar work related mandates are in force across Europe.
The Cutting Fluid Test Kits measure the key parameters necessary to optimise cutting fluid performance and enable enumeration and safe control of microbiological contamination. The basic kit is supplied with tests for cutting fluid concentration, pH, & water hardness.
A deluxe version, incorporating a dip slide incubator is also available for accurate trend analysis over a number of months.
