I'm a Chief Engineer. Apart from a brief spell of a bit over a year in the
Company office, I've only ever worked on ships, 25+ years now.
It can be a varied and rewarding career and there is a massive variety of vessels to work on. I work on North Sea supply boats - a floating version of CityLink. A guy I know left the company and has just flown out to a superyacht in Hawaii.
Well qualified and experienced people are in demand worldwide, there has been a deficit of recruiting / training over a number of years.
3 years(?) cadetship, a
starting rate of £25k ish and left to drive £30 million worth of boat. Sounds better than an apprentice plumber to me. I work a 4 weeks on/ 4 off rota, so lots of time off too.
Downsides: Personal relationships can be tough. There is a fair divorce rate. She
will miss significant anniversarys, birthdays, etc.
It's still a very male dominated industry, though that is changing slowly - I only know of 1 female engineer in 250 employees, though there are a good few more female deck officers.
I have a friend (Captain) who's son has just started a Cadetship. I think his largest problem was finding a sponsoring company to do the sea service time with - think this may be arranged via Clyde Marine but still down to individuals to satisfy the respective Company.
I've got no regrets over going to sea but it doesn't suit everyone. If she has any questions feel free to pm me.
