TSA is big enough to meet all your shipping requirements and small enough to care! Reliability, skill and efficiency are our trademarks.

Donsötank is a family company registered in 1953, and since then the business has grown and more vessels has been acquired. The company owns and operates five tankers and has around 140 employees at sea, and 14 at the office. We are a in-house vessel owner so the technical, crewing and commercial management are all in one place.
