She was launched in 1979  as a North Sea oil rig support vessel, then in 1988 she entered service with the NZ navy as HMNZS Manawanui (A09).

In July 2018 Major Projects Foundation acquired the vessel and sailed her to Newcastle, Australia. In early 2019, the vessel was  renamed RV Ocean Recovery and entered commercial survey with Cook Islands.  Antifouled in 2020 and extensive bridge refit in 2022.
