They could make it so that any vessels involved in the construction of offshore wind-farms can keep their non-American crew for the time being, but they also must have an American on board for every rank, so the ship would essentially have two full crews on board, the non-Americans are the main crew members actually in charge, but they are just being shadowed by Americans who will eventually replace them.
The wind-farm installation companies will just use the excuse that they can’t find any Americans with wind-farm construction experience, because there probably aren’t many. It will be a never ending catch-22 cycle, Americans won’t be able to get jobs on the Windfarm installation vessels because they don’t have the experience, but how can they get the experience if no companies will give them the opportunity, even in American waters.
I’ve heard of European ships going to Canada having a European crew and Canadian crew for the duration of their charter in Canada so it is not unprecedented. Wind-farm installation vessels usually have a massive amount of accommodations so there would be plenty cabins.
On these kind of vessels I don’t think the ships crew actually do that much, most of the actual work is done by project crew, they would have to try and make the project crew American also.
How much more expensive would the wind-farms be if they have to pay everyone American salaries? I’m guessing it makes wind farms a lot more economical to build because they can use seafarers on low salaries on the vessels building them.
I think DEME Offshore’s officers are mostly from Eastern Europe with some from North Europe, I have have no idea where the ABs are from, I am guessing they might be Filipino.
