Norway-based Havyard Ship Technology has entered into a contract agreement with Deep Ocean to undertake a major conversion of the subsea vessel Havila Phoenix.
Deep Ocean has chartered the ship from Havila Shipping for a period of seven years, plus four one-year options, for cable-laying and trenching operations.
The vessel’s operations are expected to begin once the conversion is completed in March 2014.
Havila Phoenix, which is based on the Havyard 858 design, was delivered from Havyard’s shipyard in Leirvik as a construction vessel in 2009.
As part of the conversion, the ship will be lengthened by 17.4m with nearly 700 tonnes of new steel, which will help accommodate new equipment for cable-laying and trenching.
The stern will be reinforced and a 250-tonne A-frame will be installed, operating together with the existing offshore crane for launching what is reportedly the world’s largest self-propelled trencher.
Extra equipment will be provided for launching smaller trenchers over the side.
A major part of the conversion would be the installation of the cable laying equipment, which includes the installation of a horizontal cable drum with capacity to store 2,000 tonnes of cable.
Havila Shipping COO Kjell Rabben told Dredging Today that the agreement is ‘a great contract’ and that ‘the company is looking forward to seeing the vessel begin operating for Deep Ocean’.
"We have good experience building vessels at Havyard and them knowing the vessel so well makes us sure that the quality of the conversion will the best we can get," Rabben said.
