The Singapore high court has approved a restructuring plan that will see OSV owner Swissco Holdings sell most of its fleet.

At the end of last year, Allianz Middle East Ship Management of the UAE struck a deal to buy 21 ships for $20.5m.

These include six anchor-handlers, tugs, barges and workboats.

Swissco also has an option to sell another four anchor-handlers (AHTS) for an extra $8.5m.
