The U.S. Coast Guard issued a marine safety alert today to remind vessel owners and operators to establish effective fuel oil changeover procedures during efforts to comply with MARPOL Annex VI emission regulations. The USCG said that several recent incidents of fuel leakages during changeovers prompted the alert. The USCG cited multiple unspecified incidents involving substantial machinery space fuel leakages that occurred while vessels were switching fuel oil to ultra low sulfur (ULS) fuel oil to ensure compliance with MARPOL Annex VI, Regulation 14.3.4. The new regulations, which came into effect on January 1, lowered maximum fuel sulfur content from 1.0% to .10%.
