SD Standard Drilling has offloaded two more platform supply vessels in depressed markets.

The Oystein Stray Spetalen-controlled company's 28%-owned subsidiary Northern Supply has agreed to sell the 3,240-dwt FS Carrick and 3,270-dwt FS Aberdour (both built 2009) for $6.6m en bloc.

VesselsValue assesses the pair as worth around $4m each.

The FS Carrick is listed as idle by shipbroker Clarksons, while the FS Aberdour is laid up.
