Norwegian shipowner PGS will bank $100m from the sale of a survey ship into Japan.

It won a tender in November to offload the 102-loa Ramform Sterling (built 2009) to Japan Oil, Gas and Metals National Corporation (JOGMEC), an administrative agency of the ministry of economy, trade and industry.

Negotiations then started over a final deal.

The owner has now signed a definitive contract, it said on Tuesday.
