Wellington is weighing up the possibility of activating one of its Otago-class offshore patrol vessels (OPVs) to temporarily take on roles previously shouldered by its hydrographic and diving support vessel HMNZS Manawanui that has since sunk.
Manawanui sank after running aground while it was carrying out survey operations in Samoa on 5 October.
All 75 crew members and passengers who were on board the vessel were evacuated, and environmental damage mitigation and investigations into the incident are ongoing.
In response to questions from Janes, a New Zealand Defence Force (NZDF) spokesperson has confirmed that a process to size up the Otago class's suitability for these operations is ongoing, and that an update on this can be expected soon.
“The NZDF and its industry partners are currently assessing the amount of work required to bring an offshore patrol vessel, either HMNZS Otago or HMNZS Wellington, to an operational level of capability,” said the spokesperson.
“That assessment work will be complete by the end of the month and will determine the timeframe for subsequent regeneration,” he added.
The Royal New Zealand Navy (RNZN) operates a fleet of two Otago-class OPVs that were commissioned in February and May 2010 respectively.
Each 85 m vessel displaces about 1,900 tonnes at full load and the class is known to have taken on military hydrography operations after the RNZN's sole dive tender HMNZS Resolution was retired in 2012.
