Germany's Hartmann Group has sold its 11-strong anchor-handler (AHTS) fleet to Breakwater Capital and Hayfin Capital Management.

The family-owned company said the recapitalisation and long-term investment through the new partnership allows it to retain full management of the ships.

The deal has been agreed with its lenders to provide "immediate stability and the potential for growth," it added. Most offshore vessel owners have had to restructure in the sector slump.
