If you can run a crewboat/workboat there’s work in Brazil. Tidewater, Chouest, Rigdon (Gulfmark), HOS have all been bringing US flagged vessel in like crazy. I know a lot of the guys that I work with (Tidewater) have a hard time getting off on time because there is no relief.
I ran crew and supply boats for years (before DP) and can still live boat tho I must admit its much easier with DP and I prefer that. I have applied to all of those companies in the past and none have even been good enough to reply that they’re not interested- why don;t they have any reliefs? probably because they aren;t interested enough in hiring anybody to return a phone call!
