While on a ballast passage from Philadelphia to Curacao,
numerous explosions, followed by fires, occurred in tanks Nos 7 to 11
on board the Liberian OBO Saint Chris,
while gas-freeing in the Atlantic Ocean
off the east coast of the United States in lat 32.15N, long 70.52W
on February 27, 1979.
Of the 40 man crew, only the quartermaster was lost.
He disappeared while standing on the bridge wing,
and was never seen again, presumably having been blown
overboard by the force of the blasts.
According to the Master, the first explosion occurred
while washing tank No 9.
The blast blew the covers of tanks No 7 to 11 overboard
and also fractured the port side iwo of No 11 tank
and damaged the bridge and accommodation.
All but the master and three crew were evacuated
from the stricken ship, which was then towed to Jacksonville
by the tug Smit Pioneer.
