Response: U.S. COAST GUARD LTR: THIS RECOMMENDATION APPEARS TO BE SIMILAR TO SAFETY RECOMMENDATION M-68-10 ISSUED FOLLOWING THE CASUALTY TO THE SS GULFSTAG (MARINE BOARD - EXPLOSION AND FIRE ABOARD SS GULFSTAG WITH LOSS OF LIFE AND CAPSIZING OF VESSEL - 24 OCTOBER 1966). THE COMMANDANT'S REPLAY AND SUBSEQUENT CORRESPONDENCE TO THE SAFETY BOARD AT THAT TIME REVEALED THAT PROVISIONS TO RELIEVE EXPLOSIVE PRESSURES IN CARGO TANKS WERE BEYOND THE STATE-OF-THE-ART FOR MARINE CONSTRUCTION. WORK PERFORMED BY THIS TASK GROUP REVEALED NOTHING TO CHANGE THIS POSITION. THE TASK GROUP IS OF THE OPINION THAT THIS APPROACH IS UNFEASIBLE AND A BETTER METHOD OF PREVENTING EXPLOSION IS THROUGH IMPROVED SAFETY MEASURES AND MORE STRINGENT OPERATING REQUIREMENTS.

Response: USCG LTR: THE POSSIBLE VALUE OF PROVIDING FOR SOME OVERPRESSURE RELIEF FEATURES IN CARGO TANKS WHERE EXPLOSIVE VAPORS MIGHT BE EXPECTED TO ACCUMULATE IS BEING RECONSIDERED.
