This is an extremely instructive casualty.
The Polar ships are a nearly unique attempt
at fully independent engine rooms.
They meet ABS's highest requirements for redundancy.
But the crew apparently felt they did not have enough excess
power on one side to run a 300 HP IG fan????
This is obviously a design fault.
So they tied the engine rooms together,
and they still did not have enough power,
even though none of the loads listed by Levine are unusual.
If fully independent means anything,
this should not be possible.
And clearly the ship needed more electrical power both sides.
CTX would not be surprised
if this were common practice on the ship.
It is doubtful if the ship was able to restore pwoer
to both engine rooms in a minute.
It is certain that power was not available
to the steering system continuously,
since there is a delay between the loss of power
and the emergency generator coming on line.
If the State DOE report is correct,
the pilots summary is at best misleading.
This casualty should have been studied carefully by the USCG,
and the detailed results published.
Instead 8 months later in November, 2002,
the SF Bay Harbor Safety Committee
which includes USCG reps reported that "The Polar Endeavor,
with a fully redundant system, has operated for one year
with escorts. The vessel has proved itself and has now
invoked its right to exemption from tug escorts."
