The ship's construction contract was awarded 20 February 1987 to VT Halter Marine, Inc. of Moss Point, Mississippi, under then name Intrepid. Her keel was laid down 26 February 1988, she was launched 17 February 1989 and commissioned as USNS Tenacious on 29 September 1989. The renaming was prompted by protests from veterans of the Essex-class aircraft carrier, who felt that the surveillance ship was not a fitting vessel to carry on the carrier's name.[1]
During the Cold War, Ocean Surveillance Ships patrolled the world's oceans searching for Soviet Navy submarines. Data was collected using the Surveillance Towed Array Sensor System (SURTASS), consisting of listening devices and electronic equipment that transmit the acoustic data via satellite to shore for analysis. SURTASS is a linear array of 8575feet deployed on a 6000feet tow cable and neutrally buoyant. The array could operate at depths between 500feetand1500feetft (andft).
Tenacious was stricken from the Naval Vessel Register and sold to New Zealand on 6 February 1997.
On commissioning into the RNZN on 13 February 1997, the ship was renamed HMNZS Resolution, after the sailing sloop, used by James Cook during his second and third voyages of exploration, in recognition of the extensive hydrographic survey work done by Cook. Resolution replaced HMNZ Ships and as the navy's primary survey and acoustic research vessel. She undertook various marine survey tasks, including for the Land Information New Zealand agency. SMB Adventure was operated by Resolution as a tender and survey motor boat.
Resolution sponsored a scholarship for under-privileged high school students to participate in a 10-day passage on the sail training ship Spirit of New Zealand. On occasion, university and high school students were embarked aboard Resolution as part of the 'Students at Sea' programme.
On 22 February 2011, Resolution was underway off Christchurch when the 2011 Canterbury earthquake occurred. NZ Navy Today said later : '..the feeling onboard was that the engines had been set in full astern with associated shuddering and shaking. It was only when a dust cloud over Christchurch was observed and chatter on VHF soon alerted the bridge team of the enormity of the disaster. With Captain Dean McDougall (CTU 654.0.1, Captain Fleet Operational Support) in an established headquarters on HMNZS Canterbury in Lyttelton, Resolution reported for duty and was subsequently called in to conduct a hydrographic confidence survey of the main channel into the Port of Lyttelton.[2]
Resolution was decommissioned at Devonport Naval Base on 27 April 2012.[3] She was subsequently sold to EGS Group, a private surveying company, and renamed RV Geo Resolution. Following the sale she left Devonport Naval Base for the final time on 11 October 2014.[4]
