I looked into this a couple of years ago, thought it might be a nice change being a subsea lumberjack in Canada rather than latching onto trees(sic), staring at pipelines or collecting crane hooks and being screamed at be ex bubble heed OCM’s but money was a joke 190 GBP a day supervising, so phone went down sharpish, you were on shore every night though, which ment your laughable money went nowhere, think your accomodation was a log cabin in the middle of nowhere.
