Tankers’ Management with OSM maritime (Chemical, Products and Oil Tankers)


Tanker ship management with OSM is a wise choice. Our experience counts more than 200 tankers. Currently, OSM manages a fleet of 100+ Oil/Chemical/Product/LPG/LNG/Shuttle Tankers under full management. This requires more than 3,000 active positions onboard and the necessary crew to replace them, which we are able to provide anytime. OSM’s Tankers’ Fleet in Q3 2022 comprises tankers of all the DWT ranges.

In regards to Shuttle Tankers’ ship management, OSM is the world’s number one third-party shuttle tanker manager. We are practically involved in this business since 1979, through Rasmussen MS, a firm acquired by OSM back in 2003. Hence, we are today the technical managers of approximately 10% of the global shuttle tanker fleet.

OSM’s greatest “asset” in the Gas Carriers segment is its broad network of experienced seafarers. Their leading-edge expertise is obtained from projects which involve FRSUs, Gas to Power projects, full crew management on multiple Offshore units and LNG/LPG/Ethylene Carriers. We deliver this expertise at a competitive cost to our customers.
