Korean shipbuilder DSME has failed in a legal bid to overturn arbitration awards against it in a $373m row over delays to Songa Offshore rigs.

The UK high court struck out DSME's application for permission to appeal the arbitration decisions on the basis the company took too long to file an application.

DSME was also refused permission to appeal the court's judgment and Songa Offshore was awarded its costs relating to the Songa Equinox and Songa Endurance claims.
