It's such a shame that the ship went under. Surely, considering it was so close to a platform, and the calm sea, someone in authority could at least have had the presence of mind to have it towed to the platform and lifted out of the sea with a crane. Or at least secured upright on the water by the crane until they'd been through their hazard analyse's.
Anyway, that aside. I wonder what the PF/PNF procedures are for arrival at the bottom of an instrument approach in poor weather. Does the PF hand over to the PNF before the minima if the PNF calls visual, and remain on instruments until landing. Thus the PNF for the approach becomes the PF for the landing. Or once visual is called, do both pilots look outside from that point until landing?
