Re: US citizen working on foreign-flagged vessels #2
OS jobs can be found through the seafarers international union, the oilfield in the gulf has been in fits and starts but jobs on supply boats can be found. Also tug companies anywhere in the US.
Is there a reason you want to work specifically on non US flagged vessels?
I worked on Marshall Islands flagged vessels but only as an engineer in the AMO. The non licensed crew members were foreign. The dynamically positioned drilling rig I worked on was MI registered but utilized Americans as OS and AB.
