Between December 12 and 30, 1969 three 210,000 dwt tankers, "Marpessa," "Mactra" and "King Haakon VII," suffered severe damage as a result of cargo tank explosions. The "Marpessa" sank as a result of the explosions. All these accidents occurred under remarkably similar circumstances during washing of the center tanks. The first report of the committee investigating the accidents developed several conclusions. One is the need for better instruments to test gas concentrations in tanks. Next is to learn the possible source of ignition with particular emphasis on static electricity. Equally important was a recommendation to use the ICS interim tank washing guide in an effort to avert future accidents.
