I’d always wondered how the NS was able to use contractors instead of full-time for that very reason: all the complexity of currencies, training, DG, HUET. Never saw contractors in other parts of the offshore world. Was explained to me as an end run around costly unionized restrictions that stalemated - unions not strong enough to displace contractors, and companies not strong enough to negotiate relief. Less safe of course, but that last percent of safe is an exponential curve costwise, and the reality is that we are “safe enough”.
