Greek tanker and bulker operator Heidmar Maritime Holdings is moving into offshore shipping through a contract with North Sea wind farm giant TenneT.

A document filed to a European Union tender website reveals that the Athens-based pools and management group has won a deal for a platform supply vessel with a maximum call-off value of €100m ($109m).

Heidmar will also supply a crew to run the ship to offshore platforms in the German North Sea.
