Hamburg-based Stella Marine Services has lost management of two products tankers to V.Ships and says future investment to replenish the fleet is unlikely unless markets improve.

Martin Strothmann, who founded the company 14 years ago, confirms the Guangzhou Shipyard-constructed, 37,800-dwt Port Louis and Port Russel (both built 2002) have switched managers after new investors acquired them.

He declines to confirm the new owners, although TradeWinds earlier reported that Port Louis was rumoured as sold to Soechi Lines of Indonesia, which works closely with oil major Pertamina.
