Havyard to construct hybrid battery powered Arctic PSV
Havyard has signed a contract for the construction of a Havyard 833 WE ICE platform supply vessel with Fafnir Offshore HF. The vessel is going to be designed by Havyard Design and Solutions in Fosnavaag and will be constructed at Havyard Ship Technology`s yard in Leirvik in Sogn, Norway. The vessel will become newbuild number 126, has a contract value of just above NOK 350 million and is due to be delivered in July 2015, the Group said in a press release.
Havyard 833 WE ICE is a newly developed platform supply vessel (PSV) design based on the most recent technology within fuel economy and environmental friendliness. This PSV is designed to operate as efficiently as possible and with the least amount of influence from exposed waters, in say, the Arctic region.
Hull lines that have recently been employed in a smaller PSV design (Havyard 832 L WE) and for windmill service vessels are developed for reduction of fuel consumption and increased comfort for crew both in calm and heavy seas. Design of the superstructure makes it easy to maintain an ice-free ship in Arctic areas. The vessel is designed according to the latest environmental demands such as Clean Design class; it has low emission engines and is prepared for catalysts. The greatest innovation onboard this vessel is that it is equipped with a hybrid battery powered diesel-electric propulsion system.
The idea of hybrid battery diesel-electric propulsion system is the same as for hybrid cars, namely to produce energy as efficiently as possible while also having access to necessary power whenever it is needed.
A typical PSV has large variations within its energy needs depending on the operation being carried out. Going from A to B demands a certain need for energy and a different need is created when it is operating by an oil rig. Weather and wind conditions, waves and currents, also play their part in the swift variations of energy requirements.
Arve Helsem Leine, Design Manager of Havyard Design & Solutions said: "The hybrid system for this ship was developed in close cooperation with Norwegian Electric Systems... This hull design combined with hybrid battery power ensure that a PSV in given operations uses 30 to 40% less fuel compared to a traditional PSV".
This latest contract is the second Havyard has signed with the Icelandic offshore shipping company Fafnir Offshore. On 4th April the hull of Havyard`s newbuild 120, Fafnir`s first newbuild, arrived the Leirvik shipyard in Sogn, Norway. Steingrímur Erlingsson is the founder and CEO of Fafnir. Erlingsson has a background as a fishing boat owner and he has amongst other things operated a shipping company in Canada. After selling off his fishing interests he was looking for fresh investment prospects and focus turned to the offshore oil industry.
General characteristics of Havyard 833 WE ICE:
Length: 89.7 m
Breadth: 19.6 m
Speed: 15 knots
Deck area: 1000 m2
