Ship Fuel Treatment and Testing

Ship Fuel

Ship Fuel is everying to a ship, poor quality fuel can lead to the poor efficiency of ship engines and even worse endanger the lives of the crew and the risk of losing the ships cargo, our ship fuel treatments and test kits have proved themselves time and time again, with ships all over the UK and world benifiting from better effiency, increased reliability and the life of ships engines extended.

Ship Fuel Treatments

ship fuel water absorbent Ship Fuel

Ship Fuel Water Absorbent

Fuel water Absorber Treatment

Fully concentrated additive for the removal of condensation or contamination water from fuel storage tanks which is a particular issue in a marine environment. May also be used for vehicle tanks with up to 1% water contamination.

•Mixes easily with all fuels
•Does not form gel deposits on contact with water
•Will not affect engine performance
•Rapid Action of the additive micronises the water thus reducing its total capacity and allowing it to be burned off in the fuel
• Compatible with all types of fuel
• Improves engine performance and fuel efficiency

To Use: First estimate the amount of water contamination, storage tanks are unlikely to have more than 1.0%, If possible drain off any larger volumes of water.

Add the Ship Fuel Water Absorbent to remaining Ship fuel and then mix or charge with new fuel.  Ship Fuel Water Absorbent will absorb into the fuel up to its own weight in water, e.g. a 30,000 litre storage tank with 400ppm water contamination (12 litres) will need approximately the same amount of additive.

Use of 250ml bottle to a standard fuel tank is usually sufficient and should be added prior to refuelling. Very high levels of water contamination should be drained off where possible.

Pack Size: 250 ml (also available in 25 litre drums for commercial use)

Ship Fuel Catalyst

Combustion Improver Treatment

Highly concentrated mixture of additives and low odour, high flash solvents which when mixed with Ship fuel will reduce ash deposits, improve burning, help emulsify water and reduce smoke emission. Enhances engine performance and cost efficiency in through a cleaner burn of heavier fuel particles which are then successfully consumed during combustion in marine applications. Ignition temperature is lowered and so combustion improved. Thus existing sludge is removed and dispersed. Reduces acid corrosion by reducing sulphuric acid formation in the cooler parts of the engine. These include cylinder liners, valve stems, exhaust trunking and funnel uptakes. The lubricity additive in the product reduces engine wear. Engine and exhaust components are kept cleaner with less maintenance and cleaning required.

Instructions for Use:

In normal Use: 250 ml will dose 1500 litres.

Dose directly into the ship fuel tank.

MBC Contaminated fuels: If the fuel has a low-medium level of MBC (check using dipslides) then a dose of 500ml per 1500 litres is required. This will allow easy burning of the ship fuel.

Use Aquabac 80 for heavy fuel contamination.

Ship Fuel Dipslide Test Kit

Contains 10 x Dipslides and instruction leaflet

Bacterial testing of systems should take place on a weekly basis and when bunkering/fuelling.

Incubate the dipslides for 24 hrs at 25-3O°C (see instructions in the kit boxes for variations on this dependent what bacteria is being tested for). Combination Dipslide for aerobic yeast & fungi (RBS) This is a basic test which identifies any contamination and the level of contamination. The dipslides can be incubated in an incubator which is available from Aquamarine, or for more indicative a warm environment will suffice for incubation, near a radiator or engine. More specific advice is available on this.

Bacterial Contamination in Ship Fuel Oil Systems – Background:

Yeast and Fungi:

These are less common than bacteria, but are one hundred times larger than bacteria and, therefore, only 10,000 yeasts will attack the chemicals and as much as 1,000,000 bacteria.

They are more resistant to biocide attack than bacteria and it is necessary that the biocide used in the oil will kill these as well as bacteria.

Ease of use and a wide range of applications make the Aquamarine Dip Slide range the ideal quick solution to easy identifation of MBC.

Disposal, use and background info is all found in the easy to use leaflet enclosed in the product box.



These exist mostly as small rods. They would almost certainly always be present in the bilges and easily cross contaminate to other systems, water, ship fuel and oil.

They are detected by the Aerobic Yeast & Fungi Dipslide. The colonies are easily seen.

Microbe Monitoring

In oil technology, microbes can be defined as comprising bacteria, yeasts and fungus. All these, when present, can attack additives in the oil and change them chemically so that they no longer function in the way intended and simultaneously there is a reduction in the quantity present.

In addition to the chemicals present in the fuel oil, extra food can be provided by the addition of leakages of any fluids waste and water draining into the system. This additional food causes the microbes to multiply more quickly. Quick identification of the presence of bacteria will mean that the problem can be treated before mechanical breakdown occurs. When testing with dipslides in oil dip the slide into the water phase of the fuel oil or preferably the oil/water interphase. When testing ballast water or drinking water it should first be fully agitated or tested at the bottom and top of the tank.


Useful Information:

The Key to clean ship fuel, oil and systesms is Good House-keeping. Keep the bilges clean, sterilise your drinking water systems and tanks annually, Check the fuel regularly for bacteria, clean up oil spills and minimise the amount of water in your ship fuel. Treat ship fuel with Water Absorber and Fuel Combustion Catalyst Additive and this will keep the system and your engines in tip-top condition.
