Bunga Kelana 3 had 62,000 tons of light Bintulu crude on board
which meant she was loaded to about the 12 m waterline,
about 3 m below the full load waterline of 14.92 m.
This double hull Aframax has a 2x6 cargo tank arrangement.
MPA's current estimate of the spill is 5000 m3.
The impact was on the port side of BK3, just forward of the manifold.
The cargo tank breached was almost certainly 3P.
We have some good photos of the damage including the midships draft marks,
from which we can roughly scale off the damage.
The damage is a wedge.
The top of the wedge is one meter below the deck,
and about 13 meters wide longitudinally.
The bottom of triangle is below the 12 m waterline.
The penetration extends at least 5 meters into the hull.
With this kind of damage, there was no way they could
avoid losing at least one tank's worth of cargo,
which would have been roughly 5000 tons.
It looks like the damage extends just forward of the 2/3 bulkhead,
but 2P cargo was probably not breached.
If the ship had been single sided,
this probably would have been a two tank spill.
It looks like the impact angle was maybe 60 degrees off the BK bow,
Photo of Waily bow indicates she was loaded
which is consistent with the top of the wedge
being below BK3 deck.
Very fortunate to avoid a fire.
Inerting may have been a big help here.
No info yet on cause. BK3 was coming from Sarawak to discharge
at Singapore, so she should have been in the north (westbound) lane.
Guessing Waily was eastbound, but we will have to wait and see.
