"Kong Haakon VII", Delivered 07 aug 1969. At this time the biggest ship ever buildt in Norway,
the biggest ship in the Norwegian Fleet.

Three of the world`s biggest tankers blow up within two weeks.

On 12th December 1969 the Marpessa, a new giant tanker of over 100,000 gross tons, was off Africa,
returning to the Arabian Gulf in the Middle East to pick up her second cargo of crude oil. Suddenly, a massive
explosion occurred in one of her centre tanks, killing two of her crew and injuring others. Because of damage
to the lines on deck that carried water, it was impossible to put out the fire. Marpessa began to flood, and with
her bulkheads giving way under the enormous pressure of water, she sank on 15th December. When two other
huge tankers suffered similar explosions in the same area within the next two weeks, Mactra and Kong Haakon
VII, it was apparent that this was no coincidence.

All three tankers were cleaning their tanks at the time of the explosions. It was decided that the equipment used
to wash the insides of the tanks with water had somehow ignited the dangerous mixture of air and gas left when the
crude oil had been pumped out. Perhaps it was just a spark caused by metal grinding on metal, but one theory
held that the massive tanks of these vessels could create their own weather conditions. It is possible that the
equivalent of a thunderstorm had occurred, with catastrophic results. As a result, tank-cleaning equipment was
modified. In addition, an inert gas - carbon dioxide from the ship`s engines, which will not support a fire - is
pumped into the hold during tank cleaning.
