Win More Shipping will ask Hong Kong's High Court to order the flag administration there to take action to secure the release of a tanker detained for suspected violation of North Korean sanctions.

The 16,000-dwt Lighthouse Winmore (built 1975) has been held at the South Korean port of Yeosu since December 2017.

Win More outlined its grievances in a two-day court hearing as part of its attempt to bring a judicial review of the flag state’s failure to take action to secure the ship's release.
