We are back offshore, and this is the Sedco Energy
photographed by Jaksa Braksic off the coast of
Africa recently. This is an unusual class of
semi-submersible with the drill floor and the
derrick at one end instead of in the middle. There
are a couple of advantages in this layout. One is
that the open deck is much larger, for the storage
of all the stuff that accumulates on
semi-submersibles and the other is that the
accommodation is at the greatest possible distance
from the point at which a blowout might occur. On
the other hand the reason they put the derrick in
the middle is because the movement in adverse
weather is minimised. You take your choice, and it
might be significant that not many people have made
this one.
