Friend at OSG gave me inside scoop on pay over there for mates. 3M pay is pretty much directly from the company when he got hired last summer. 2M and CM pay are from what he was told. 3M/2M vacation 27:30. CM/Capt 30:30.
Probationary 3M: $618/day ($311 for holidays)
3M: $731/day ($355 for holidays)
2M: $850/day
CM: $1050/day
Capt: not too sure at all but probably around $1250-$1350
Probationary period is for first two trips so give or take about a year before regular 3M pay including vacation time.
