275 pounds is too heavy to be safe on a job-site in the North Sea.
How did you determine that? You have any idea how easy it is for a man 6 foot or taller to get over 275 if they work out or just work hard?
Honestly, it isn’t that hard, especially if you are over 6 foot. I am 6 foot myself and in my younger days of muscle work, over brain work I do now, I hovered between 270 and 285. In high school I was 190 before I even graduated and was a fit wrestler, as a boy / teen grows to real manhood that weight keeps increasing easily.
That was just from the calories needed and work required.

I’ve worked rigs on the North Sea and am over 275. Mind you, I am almost 7 feet tall. My waist is 33” and am in the low teens of body fat.
You just sign a waiver saying “you know you’re screwed”, take the training for the boats and move on with life.
