MIT79 is wrong.
There was some communication,
but it did not involve all the parties.
It is nuts that two ships from the same company don't communicate.
Nuts that Oregon did not want to talk to HAR.
Nuts that HAR operator who was watching the whole thing unfold
did not try other channels to talk to Oregon.
In a sense this collision was very unusual in that at least
one ship tried to communicate with the other.
Invariably, unless pilotage is involved,
neither ship tries to talk to each other, at least prior to 2000.
CTX would like to list failure to communicate as a collision cause,
but it would be almost redundant.
OSIR puts the spill at 840,000 gallons of No 6 fuel oil.
Cahill has a pretty detailed description of this casualty.
It appears to be based on the USCG Investigation,
and like the USCG report, puts everything in terms of speed over the ground.
USCG says tide was 1.5 to 2 kts settingto the NE.
Cahill says eddies, etc right at the Bridge could push this locally
to as much as six knots.
