Reminder from Marshall Islands and the USCG about the importance of establishing effective fuel oil changeover procedures to comply with MARPOL Annex VI emission regulations.

The Maritime Administrator of the Republic of the Marshall Islands has issued the following attached Marine Safety Advisory (MSA) which concerns ultra low sulphur fuel oil and compliance with MARPOL requirements before entering and while operating within Emission Control Areas (ECAs).

See news attachment for MSAdvisory 9-15 Rev.1 (USCG-Ultra Low Sulfur Fuel Oil & Compliance with MARPOL Requirements).pdf

Indeed, the United States Coast Guard (USCG) has published Marine Safety Alert 13-15 (attached to this MSA and which updates Safety Alert 2-15, dated March 3, 2015) reminding vessel owners and operators about the importance of establishing effective fuel oil changeover procedures to comply with MARPOL Annex VI emission regulations.

This updated safety alert outlines the USCG’s strongly recommended measures that vessel owners and operators should take to ensure smooth operations and effective compliance and provides links to open internet sources for informational purposes.

Indeed, the Coast Guard strongly recommends that vessel owners and operators ensure the following measures are completed as part of their fuel oil switching procedures :

  • Ensure fuel oil switching is accomplished outside of busy traffic lanes and the ECA. Generally the ECA is 200 nm from the North American Coast and 50 miles from the U.S. Caribbean coast (e.g., the Commonwealth of Puerto Rico and the U.S. Virgin Islands);

  • Utilize their technical resources to develop safe operations and maintain full compliance with emission requirements;

  • Consult with engine and boiler manufacturers for fuel oil changeover guidance and to determine if system modifications or additional safeguards are necessary;

  • Consult fuel suppliers for proper fuel selection;

  • Ensure all sensors, controls and alarms (e.g., pressure, temperature, viscosity, differential pressure, and flow indicators) are operational and function as designed;

  • Ensure system piping, seals, gaskets, flanges, fittings, brackets, etc., are maintained.

  • Ensure detailed system schematics are available;

  • Review and update fuel oil changeover procedures as needed;

  • Establish a fuel oil system inspection and maintenance schedule;

  • Remember that the energy content of a given volume of ULS fuel oil may differ from residual fuel, such that existing throttle settings may not give the desired propeller shaft RPM or generator loads; performance and speed trials on ULS fuel oil may need to be conducted;

  • As part of the master-pilot information exchange (as required by 33 CFR 164.11(k)), discuss the vessel's maneuvering characteristics, including any change in RPMs associated with ULS fuel oil;

  • Determine if using ULS fuel necessitates amendments to the pilot card (see IMO RES A.601(15) and NVIC 7-89);

  • Review and update fuel changeover procedures based on lessons learned;

  • Provide initial and periodic crew training for accomplishing safe, effective and leak-free fuel switching; and

  • Anticipate that there may be many technical challenges for operators when beginning to use ULS fuel oil as a matter of routine and compliance. These range from excessive leakages of fuel system components, increased wear and tear on these components, lack of lubricity of the fuels and the need for possible changes in maintenance schedules, operational methods, etc.
