Pieces Still Missing from the Jigsaw Puzzle
Sparing continues between the ERRV Owners
Association and BP on the merits or otherwise of the ERRV or the helicopter
as means of rescuing people from the sea. BP of course has a more difficult
task than the ERRV owners since they most somehow promote the advantages of
the new scheme without being too nasty about the existing facilities.
Everyone would be in bad trouble if BP managed to prove that the standby
vessels were no good at all.
There is no doubt at all that some of the
standby vessels operating today are first class vessels, new well designed
and well found, some of them with excellent towing gear. We might think that
is it almost a waste of a good ship to have them just floating around
installation doing nothing in particular. Or is that lending weight to the
BP argument?
The latest salve in this war has been fired
by the ERRV who have published BPs answers to their original list of
advantages, with their own answers to the answers. The full list can be
found at www.errva.org.uk and all of
it makes interesting reading. But there are a few areas which are worthy of
particular comment.
To the ERRVA claim that their vessels were
always available and ready, BP responded that the ships did not provide a
rescue service in weather conditions above 47 knots and 7 meter seas, and in
any case crew safety should be considered. Good point, but we thought that
helicopters had a start-up limit of about 55 knots, so not too much
difference there.
The ERRVA reposted with facts about the West
Gamma rescue carried out by an FRC from one of the Esvagt ships, which is
true, but Esvagt have special techniques and special FRCs which allow them
to operate in very rough weather, while the rest of the market has tended to
move towards larger daughter craft which would be difficult to launch and
impossible to recover in adverse weather..
Later in the discussion there is an exchange
about back-up by other vessels, where BP claim that standby vessels have a
slow response speed, as little as four knots in adverse conditions. This is
slightly shaky ground for all operators, who make all sorts of
justifications for sharing ERRVs between more than one platform or between
an platform and a rig. At one point they do use the words "...well
beyond the two hour performance standard we have to meet."
This is where it all gets a bit difficult to
understand. Can anyone imagine what it would be like to be in the North Sea
for two hours? And even if you can, would you expect your employers to
actually plan to leave you in the water for that
long?
