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

Tankers Management

OSM’s experience counts more than 200 tankers of all types.
Currently, OSM has a tankers' fleet of approximately 100 ships under full management and more than 3500+ active positions onboard.

We believe that quality management can be achieved only by highly skilled and trained seafarers in combination with top-of-the-notch systems/platforms, experienced shore employees, and well-defined processes. All these are ingredients that can lead only to a single result: Quality Management for our tankers!

shuttle tanker crew and technical management by OSM Maritime-min


OSM has the longest experience as a shuttle tanker operator. OSM Ship Management AS was previously named Rasmussen Maritime Services AS (founded in 1977), until OSM acquired Rasmussen MS in 2003. Rasmussen MS has been a shuttle tanker operator since 1979; Polytrader and Polytraveller were the first shuttle tankers in the world and they were operated by Rasmussen MS. These ships, and many more other shuttle tankers, were still in the fleet when OSM acquired Rasmussen MS.
