MARPOL Annex VI regulations for the prevention of Air Pollution from ships assign Sulfur Oxides (SOx) Emission Control Areas (ECA) with more stringent controls on sulfur emissions. Starting January 1st 2015, the rules to use fuels with 0.1% maximum sulfur content will be extended to include all ECAs.

According to the Coast Guard, ship operators must document their fuel use with bunker delivery notes — for those over 400 gross tonnage, as well as take fuel oil samples at the time of delivery and have discrete written fuel oil changeover procedures, showing how and when the fuel oil changeover is to be done to ensure that only compliant fuel oil is burned within a designated ECA. In addition, a fuel oil changeover logbook must document the volume of compliant fuel oil in each tank as well as the date, time and position of the ship when any fuel oil changeover operation is completed before entry into or commenced after exit of a designated ECA.
A direct improvement of air quality will be gained, particularly in densely populated coastal regions, but as we all know, while the sulfur content of fuel does create emissions that pollute, it also has a lubricating property that is beneficial to engines. Removal of it tends to lead to abrasive wear. Reducing the level of Sulfur compounds in the Marine Fuel Oils can reduce the ability of the oil to lubricate the injection system of the engine, causing the fuel injection pump of the engine to fail. Lower lubricity can significantly increase wear of fuel pumps, valves and injector nozzles over an extended period of use. It is clear that operators need to act decisively and take measures to protect their equipment. We at MARICHEM MARIGASES have the ultimate solution:


  • Provides superior lubricity properties to the HFO, MDO & MGO.
    One additive for all kinds of fuel.
  • Prevents wear on contacting metal surfaces and their fail.
  • Reduces significantly injector deposits.
  • Protects fuel systems against corrosion and will not separate in the fuel tank.
  • Contains dispersants and anti-corrosion agents.
  • Well dispersing product into the fuel.
  • Does not contain chlorinated solvents.

F.O.T.–LS provides superior lubricity properties to the marine fuel oils. Furthermore contains detergent and dispersant additives to prevent problems associated with the accumulations of injector deposits. F.O.T.–LS significantly reduces injector deposits and therefore has a positive effect on emissions (smoke, carbon monoxide, unburned hydrocarbons and particulates). Additionally, the fuel system is protected against corrosion.
F.O.T.–LS should be dosed directly in the fuel storage tank, preferably prior to bunkering.
