Two conversion contracts

Nauta has signed two contract for major conversions of the vessels.
The first contract has been signed with a Norwegian client and is connected with the lengthening and fitting some of the elements of the new equipment on board subsea vessel  Havila Phoenix.


The vessel shall be used for cable laying and trenching for offshore wind mill installations. To enable the vessel for these operations it needs to be lengthened with 17,4 m to accommodate new equipment. The lengthening means that close to 700 tons new steel shall be installed.

There will be installed a lot of new equipment both on and below the cargo deck. The stern will be reinforced and a 250 tonnes A-frame will be installed, operating together with the existing offshore crane for launching the biggest trencher. This trencher is the world’s largest self propelled trencher.
Equipment for launching a smaller trencher over the side will also be installed.
A big part of the conversion will be to install the cable laying equipment. This includes installation of a horizontal cable drum with capacity to store 2000 tons of cable. Totally around 100 persons will stay onboard during the marine operations.
