New Vessel for Hydrographic and Diving

The New Zealand government has approved NZ$103 million for the purchase and refit of a second-hand multi-role offshore support vessel that will be used as a dive and hydrographic support vessel by the Royal New Zealand Navy.

Following purchase, the 85-meter Norwegian-built survey vessel MV Edda Fonn will be outfitted with the dive and hydrographic systems required by the defense force.

MV Edda Fonn will replace hydrographic ship HMNZS Resolution and dive support ship HMNZS Manawanui. The two vessels were decommissioned from the RNZN in 2012 and 2018 respectively, following several decades of service.

“This vessel will ensure that the current capability gaps for diving and hydrography are filled as quickly as possible, with a proven, well tested platform,” says Minister of Defence Ron Mark.

The ship is scheduled to be delivered to Devonport Naval Base in May 2019. It will feature a 100t salvage crane, a remotely operated vehicle and a contemporary dynamic positioning system, which will allow Navy’s specialist divers to achieve greater levels of effectiveness and safety, in a greater range of conditions.

The New Zealand Navy was initially scheduled to receive a custom, new-build vessel but an NZ$148 million cost blowout in the country’s frigate upgrade project forced the government to consider a used vessel.

Defense officials identified the MV Edda Fonn, owned and operated by Norwegian company Østensjø Rederi, as the most suitable option from an initial list of over 150 candidate offshore and subsea support vessels.

“Defence officials have subjected the Edda Fonn to considerable scrutiny ahead of purchase,” says Ron Mark. “We have been assured by independent experts that it is in excellent condition, and will handle well in the operations the Defence Force will use it for,” says Ron Mark.

The vessel generally operates in the North Sea, and is under lease until the end of 2018, following which the modification process will begin.

Once delivered, final modifications will be undertaken in New Zealand. It is expected that New Zealand industry will be involved in this part of the project. The ship is expected to be in service with the Navy by November 2019.

The NZ$103 million project budget is for the purchase, modifications and introduction into service. Thanks Red M for the article.

The deck equipment includes two Effer 17tm cranes that can carry out a 1.62t lift at 10.29m and a Heila 15tm provision crane that can lift 1.1t at 14.76m. It has a 10t Karmøy tugger winch and a Hydramarine 1.1t 2,500m wire transponder winch. There are two anchor windlass/mooring winches forward and two Karmøy capstans aft.

In order to maintain stability there are three anti-rolling tanks and an automatic / manual active heel system with a capacity of 2,000m³/h.

The accommodation includes 41 cabins with 66 beds. This breaks down into four state cabins, 18 single berths with bathroom, 11 double cabins with separate bedroom and shared bathroom and eight double berth with bathroom.

There is an on-line data room, an off-line room, six offices, a conference room, an enclosed ROV hanger / workshop and an ROV transformer room.

There is also a gymnasium, sauna, sunbed, three dayrooms, duty mess, mess room and galley.

Within the vessel is a 7.2m x 7.2m moonpool as well as a 1,200mm diameter mini-moonpool prepared for a multibeam echo sounder. The helicopter deck is designed for Super Puma (9.3t).

    The navy originally wanted a vessel that had a moon pool, centred within the ship which has direct access to the sea for operating the submersible and divers in all weathers. Does the “contemporary dynamic positioning system” cover that?

    The big question – white or grey. It’s currently looking very grey, guess that means fresh drop of top coat white.

  5. Jim D says:

    The last two ships that were hydrographic and diving (Manawanui and Resolution) were painted grey. The last ships painted white were Monowai, Takapu and Tarapunga.

    Nik,
    Have a look at the current photos on the link in franks input, I think you’ll find the Grey picture has been photoshopped, as the Edda Vonn is a very nice Orange and yellow colour scheme at the moment working off Portsmouth!!
