One point to add for those outside the north sea, is that the pilot flynig isn't always the Captain (PIC). If the rig (dependant on wind and other obstacles) is on the left then the Co-Pilot will do the talk down then actual landing with the captain flying the approach. This can be changed dependant on the experience of the crew, but would mean a more complicated hand over at the "bottom" (decision point).
I will echo HB about the fact we don't take chances or risks as we are taking people to work, not saving lives (i.e. SAR).
