MV Ocean Recovery is a 43-metre dive support vessel, with berths for 28 people and a displacement of about 1000 tons, (gross tonnage  498 tons).  She has a beam of 9.2 meters, a draft of 3.2m and cruising speed of 9 knots. She has an afterdeck cargo capacity of 150 tons. 

She has a recompression chamber, dive bell and a surface air system to supply divers to 30m. The crane can lift 15 tonnes alongside, and 5 tonnes fully extended.  A four-point anchoring system enables her to hold precise position when moored.  She is SOLAS compliant.  Twin Caterpillar engines are rated at 455kw each.


Built in 1979  as a North Sea oil rig support vessel, HMNZS Manawanui served with distinction in the New Zealand Navy.

In July 2018 Major Projects Foundation acquired the vessel and sailed her to her new home port of Newcastle, Australia. 

In early 2019, the vessel was officially renamed MV Ocean Recovery. 

She is undergoing refit, systems update, registration and refurbishment before undertaking projects under the direction of the foundation.
