Second, the decks are not covered in ice. Are they heated? Otherwise, I have my doubts about that. Here's what Claude says:
Yes, the decks of oil platforms in the North Sea can get covered with ice, although it is not a widespread or catastrophic problem for the region. Sea spray can loft water onto decks when waves exceed 10 meters in height, creating slippery fall hazards. However, the North Sea's reputation for severe weather has historically not created significant icing problems for these platforms, with ice loadings on rigs typically ranging between 225 and 450 metric tons. That's a lot of ice.
While yours is a fair answer, somehow though, I just don't see decent people not risking their necks to save others. IOW, you do depend upon them but won't admit it.
The ice is not on the deck. It’s around the pilings.
The concern is not a person slipping. The concern is the ice catches waves and rips out your moorings and you go adrift.
