Our personnel

Completing our mission 365 days per year requires the best from our crews.

At N-O-S we have a unique personnel policy for our crews: We have two crews for every CTV. All crewmembers are employed full-time by N-O-S; no one starts their shift tired from their other part time job. At N-O-S the phrase “our employees is our most valuable asset” is not a cliché.

Our fleet

High performance, multipurpose CTV: s.

Northern Offshore Services offers you access to a fleet designed to meet the highest standards. This is of course true for our newest vessels but also for the older members of our fleet: we continuously update our fleet with rebuilds and conversions.
