Greetings- I see your asking for work and I feel for the many people trying to get by. I'm going to paste a chapter from my book "How to make money with boats". It's 50 small businesses run from a boat, but many of the ideas might be interchangeable with your skill set. This chapter contains all the ways I have seen people earning a living in the marine world working the welding trade. Hope this long post does not crash the system.
Might give someone some ideas.

Okay, the post exceeded the allowable length, so I put it on our website. Sorry no photos, but the text is there and it gives a series of small time money making jobs for welders. Not pipeline stuff, and aimed at boats but it might spark an idea or two.
