Servicing Siemens' windfarms

Havyard Ship Technology's newbuild 119 'Esvagt Faraday', a Havyard 832 SOV windfarm service vessel, is the second to be delivered to Esvagt. The first, newbuild 118 'Esvagt Froude' was delivered in the middle of February. The German company Siemens Wind Power has hired both vessels on long-term contracts to service their offshore windfarms. 'Esvagt Froude' is on a five-year contract for Siemens and will service the windfarm Baltic 2 in the Baltic Sea, while 'Esvagt Faraday' will be on a ten-year contract and will service the Butendiek project in the northern part of the German sector of the North Sea.
The feedback from the first windfarm service vessel 'Esvagt Froude' is good, and the shipping company and the operator are looking forward to putting 'Esvagt Faraday' into operation.
The contract for the first two Havyard 832 SOV windfarm service vessels was entered into in July 2013. Esvagt has also ordered an additional Havyard 832 SOV from Havyard. It will be under contract for Dudgeon windfarm, which is operated by Statoil.

Development and testing
The Havyard 832 SOV is a new Havyard designTM in what is a new market for Havyard. The basis for developing a new design of this kind is the wide-ranging expertise and experience Havyard has in designing and building advanced offshore and fishing vessels.
'There will always be challenges in connection with the development and production of new products, which was also the case when we built the first windfarm vessel,' says Lasse Stokkeland, head of Havyard Ship Technology AS. 'The advantage of being in control of both the design and building of new types of vessels is that it gives us an opportunity to test new solutions and identify any changes that need to be made before other vessels are built, either at our own yard or at an external yard. Although the second vessel followed hot on the heels of the prototype, a lot was learned during the building of the first vessel, which was a great advantage during the execution of the second project. We are very well equipped to build even more ships for this exciting market, or to provide support to other yards that want to build our design,' concludes Stokkeland.

Control of the value chain
Build 119 was fitted out and completed at Havyard Ship Technology AS in Leirvik in Sogn.
Havyard Design & Solutions in Fosnavåg has delivered the design and detail engineering for the production of the vessel. In addition, Havyard Power & Systems, which is based in Ålesund, delivered the electrical engineering, automation and alarm systems, and Havyard ConceptBridgeTM.
Havyard Ship Technology now has fishing vessels, live fish carriers, offshore vessels, icebreakers and service vessels for windfarms under construction for shipping companies from Norway, Iceland, Denmark and Russia.
In addition to designs for the building of ships at Havyard's own yard, Havyard Design & Solutions also has orders for the delivery of design and equipment packages for the building of ships of Havyard designTM in Brazil, Spain, Singapore, India and China. Since 2005, 79 vessels of Havyard designTM have been built or are under construction.

The shipping company
ESVAGT was formed in 1981 and its head office is in Esbjerg in Denmark. It operates in the fields of emergency response and anchor-handling vessels, safety training, oil spill response and personnel transport and service for offshore accommodation modules and wind farms. ESVAGT has a fleet of 39 ships and additionally five newbuilds, including the three vessels under construction at Havyard.

Havyard 832 SOV
The Havyard 832 SOV design has been developed by the Herøy-based design company Havyard Design & Solutions. The design for this contract has been specially adapted to meet the requirements in the assignment description from Statoil for Dudgeon offshore wind farm. The ship's main job will be to provide accommodation for and carry personnel and equipment for the performance of service and maintenance on offshore windmills. Among other things, this means that the ship has a specialised gangway system that makes it possible to transfer personnel from the ship to the windmills in harsh weather conditions. Otherwise, emphasis has been placed on good facilities and comfort for the personnel on board, the ability to stay in position by the windmills, and environmentally friendly and economical transit between onshore bases and the windmills offshore. Havyard 832 SOV has a foreship designed to have good properties in both calm and rough seas and a stern with twin skegs that improve the performance of the hull and propellers and their operating economy.
