Entry Level Jobs?

I am interested in working offshore, I am probably over the age that companies would consider hiring me at 52 years old. I have worked in a lot of different industries, oil field construction, swamper on a winch truck, welder, dozer/backhoe operator and for the last 22 years I have worked in the manufacturing industry.
Are there any companies that would hire a 50 year old to a entry level position?
I have been behind a desk for the last 20 years looking at a computer screen, using AutoCAD detailing grating, and I’m about to lose my mind.
I am open to any entry level, rig, boat, barge
Any suggestions or tips from anyone?
