Another one here..... I work for Subsea7 with ROVs (remotely operated vehicles for those not in the offshore game) 6 years now.
Mainly on Semi-submersible drill rigs, but sometimes boats, jack-ups etc.... most of the time working from Aberdeen in the northern sector, west of Shetland etc but do occasionally work in Congo, West Africa, Norway and the southern north sea.
Currently on the GA3 semi-submersible, been on here for about 3 years now doing 3 weeks on,3 off.
Don't like being away from the family but love the the job, pretty interesting. Love the time off!! (and the money)
