HMNZS Otago (P148)

HMNZS ''Otago'' (P148) is a in service with the Royal New Zealand Navy. The development of the OPV design based on an Irish Naval Service OPV class was very contentious, with the RNZN arguing for the need for a limited combat suite for effective training and patrol work with a 57 mm–76 mm light frigate gun and associated fire control, radar and electronic warfare systems at least compatible with current 2nd light RN OPVs. The government and Cabinet preference was to use the space and extra finance available to incorporate ice strengthening and provision of extra coastal patrol vessels. The RNZN view was that adding ice strengthening was unnecessary for Southern Ocean patrols, distinct from operations in the Ross Sea, and the extra weight and complexity would stress and shorten the life of the hulls from 25 to 15 years. She was launched in 2006 but suffered from problems during construction and was not commissioned until 2010, two years later than planned. Soon after commissioning ''Otago'' encountered problems with both her engines which delayed her arrival at her home port of Port Chalmers. She has served on several lengthy patrols of the Antarctic, though she lacks the capability to operate in heavier levels of ice-coverage which has led to the cancellation of at least one planned operation.

Name

The ship is named in honour of the New Zealand province of Otago, associated with the city of Dunedin. The previous , was a that served in the Royal New Zealand Navy from 1960 until 1983.

Construction

The ship was built by Tenix as part of the New Zealand government's Royal New Zealand Navy plans, and was expected to enter service in late 2008. She was launched in Williamstown, Victoria on 18 November 2006 and sponsored by Dame Silvia Cartwright. The first commanding officer of ''Otago'' was Lieutenant Commander Simon Rooke MNZM.

''Otago'' suffered delays in delivery. In late 2008, it became known that the vessel was not considered to meet all contract specifications, and exceeded her design displacement. The initial crew stationed in Melbourne to commission the vessel returned to New Zealand while the build was completed. On 18 February 2010, the ship was accepted into the RNZN after the builders claimed that being slightly overweight would not stop her from patrolling in Antarctic waters. In mid March 2010, the vessel developed problems in both engines during sea trials, and had to limp back into port in Australia, instead of arriving in Auckland as originally planned. HMNZS ''Otago'' eventually arrived in Auckland in April 2010, nearly two years after the original target date.

Service

HMNZS ''Otago'' made her first visit to her home port of Port Chalmers on 22 July 2010. On her maiden voyage ''Otago'' encountered trouble when sea water contaminated her bunker fuel. She suffered further technical difficulties in December 2010 during a visit to Campbell Island with her engineers having to make temporary repairs to both engines prior to an early return to Devonport Naval Base for repairs. Governor-General Sir Anand Satyanand and cabinet minister Kate Wilkinson who were on board at the time were transferred to to continue their tour.

Lieutenant-Commander Robert McCaw assumed command of the vessel on 12 September 2012. Since then she has served on lengthy patrols of the Antarctic, though a planned mission to monitor fisheries in the Southern Ocean had to be cancelled because the vessel lacked the capability to operate in that level of ice cover. Her duties have included fisheries protection, conservation and transportation of scientific staff. The scientists carried by ''Otago'' discovered 90 new species of seaweed on a single Sub-Antarctic island. The vessel has also conducted two search and rescue operations.

In August 2019 ''Otago'' proceeded to Samoa and American Samoa, where she met with the US Coast Guard cutters and . The three vessels worked together as they visited ports together.

Upgrades

Both ''Otago'' and ''Wellington'' have recently gone through minor upgrades, including sensors and weapons, and replacing the 25 mm Bushmaster with the Rafael Typhoon 25 mm stabilised naval gun. Full compatibility trials with the updated Seasprite SH2G1(l)s, ex RAN were conducted in 2016 and the much more capable helicopters are now deployed from ''Otago''Lt Cdr A.
