Here is a taste of what it is about it is a special environment in special conditions, and everything related to it is special and limited.
I wonder if this is what drew the attention for the study, “the average weight of offshore workers had risen by almost 1st 7Ib (10kg) since 2008.”

Transcript
So we looked at how people’s uh weight predominantly but also their size
affects them from the moment they turn up at the helport, they step on the helicopter, they travel offshore. We
looked at aspects of normal offshore life like going up and down stairs and this affects everything like the beds,
the mattresses. Um we looked at um normal work, so confined space, working
at high areas which we have acute issues with. And then we looked at emergency response and that’s where we started
running into some particularly um challenging issues. So we looked at um
donut devices and other descent devices that get you off the platform and at the very last minute. We looked at um life
raft capacity, lifeboat, seat belts, lifeboat um you know capacity for the
number of people on board and there’s issues right the way across all aspects of offshore work. But one area which and
actually the coast guard wrote to us about which is common across every single installation whether uh no no
matter what type of installation is around the helicopter winch capacity that is in the um that’s on all of the
search and rescue helicopters both the industry one and the government search and rescue helicopters. and that winch.
Once you take off the average weight of a um rescue paramedic, their equipment,
When the industry realised weight was a problem
and the stretcher, then um you’re really only left with that 124.7, which we
rounded down to 124 to give us a nice uh safety margin there, but also a real
clear number that everyone could uh could understand. So, so the the number
itself is derived from the helicopter winching, but the risks that we’re mitigating are right across all aspects
