Maersk Supply Service has completed a vast fleet renewal programme, but a question mark still hangs over the company's future.

The offshore support vessel specialist is the last of AP Moller-Maersk's four energy businesses yet to find a plan to separate from the group as part of a major strategy shift.

In the past three years, Maersk Supply has divested 23 platform support vessels and anchor handlers (AHTS), and taken delivery of 10 new AHTS and subsea support vessels.
