Tycoon Oystein Stray Spetalen's SD Standard Drilling has increased its ownership in six platform supply vessels (PSVs) formerly controlled by collapsed World Wide Supply (WWS).

It said it had struck a deal with Royal London Asset Management to acquire 2.5m shares in New World Supply (NWS), set up by bondholders to take over the fleet.

This corresponds to approximately 7.7% of NWS shares.
