Both ships were eastbound off Port Dickson.
The Ostende Max was in ballast for Singapore.
The Formosaproduct Brick was loaded with 58,000 tons
(some say 53,000) of naptha for Korea,
but intended to bunker at Singapore.
The collision occurred in the Precautionary Zone
off Port Dickson;
but we don't know if the Ostende Max
was leaving Port Dickson
and entering the eastbound lane.
The starboard bow of the Ostende Max
hit the port side of the Brick,
just forward of the bridge at a fairly shallow angle.
The time was 2052; weather was reported clear.
There was an immediate intense fire
that engulfed the port side of the accommodations.
The bulbous bow of the Ostende Max was
pushed way to port.
Quotes from the Brick survivors hint
that they were surprised by the collision.
There appears to have been no communication.
Videos taken while the ship was still on-fire
show little or no wind.
9 killed on the Brick, others hospitalized,
and 2 or 3 seriously hurt on the Max.
Several reports say "no spill" but videos
show an extensive burning slick,
and the Brick ended up with an 11 degree port list.
The damage extends for the deck to below the waterline.
In this situation, you will loose
everything in at least one tank,
and there will be very little side capture.
This ship has a 2x6 tank arrangement,
so one tank wouldhave been about 4800 tons.
For now CTX is ball-parking the spill at 5000 m3.
It is likely that almost all of this naptha burned.
Sounds like Ostende Max was attempting
to enter the eastbound lane from Pt Dickson,
but this is just a guess.
Fortunately, the Ostende Max was
registered in the Isle of Man,
so we should get a rare, meaningful flag state report.
Fire/smoke may have been pulled thru the accommodations
by HVAC system.
