Allianz Middle East Ship Management of the UAE has struck a deal to buy most of the OSV fleet of restructuring Singapore owner Swissco Holdings.

The Swissco judicial managers said Allianz is paying $20.5m for 21 vessels, including six anchor-handlers, tugs, barges and workboats.

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

Two of these are going to other buyers: Newport Marine Services is acquiring the 4,815-hp laid-up AHTS Swissco Sapphire (built 2007) for $0.83m
