Greek shipowner Interunity Management Corp has entered Hansa Tankers' chemical tanker pool with three ships.

The vessels are the 21,300-dwt Chem Bulldog (built 2010), the 20,600-dwt Chem Tiger (built 2003) and the 19,900-dwt Chem Wolverine (built 2006).

Magne Morken, managing director of the Bergen-based tanker operator, confirms the move.

It comes as shipowners have been moving ships in and out of the pool.
