Ship had loaded 57,000 tons of AH at Ras Tanura, was approaching Ash Shihr SBM in Yemen
when hit by explosives detonated from a small craft alongside 4S.
Damage must have extended into one of the few loaded tanks
whose cargo caught fire.
The fire burned for 36 hours.
Main damage extended 2-3 m above waterline,
so no chance to trap oil in double sides.
See pictures at CEDRE link.
One of the CEDRE sources says 12,000 tons was burnt/spilt.
Seems high. Need confirmation.
