The ship is scheduled to be delivered to ESVAGT ultimo 2017. It will be used under a contract with the Danish wind power company Vestas to service the windfarms Nobelwind and Belwind.

New niche
The windfarm service design Havyard 831 SOV was developed in close cooperation between Havyard Design & Solutions and ESVAGT, and it is aimed at a new niche for vessels of this kind. Vice President Sales Gisle Vinjevoll Thrane of Havyard Design & Solutions sees a great potential in delivering more such designs in the time ahead. 'The market for big service vessels for offshore windfarms is a relatively new one, and, in cooperation with ESVAGT, we have entered this market at an early stage,' says Vice President Sales Thrane. 'The windmills used to be serviced by small, fast-moving boats that transported personnel and equipment daily to and from the shore. More and more windfarms are now serviced by bigger ships where the service personnel work and live on board for prolonged periods and access the windmills by means of a gangway installed on the mother ship or small boats launched from the mother ship. This is a safer and more profitable way of servicing the windfarms, particularly those far offshore.'
'Havyard 831 SOV was developed to fill a new niche in this market, namely smaller windfarms. The new design is smaller than the ships built so far. It is compact and efficient, but at the same time has ample capacity to transport service personnel and equipment. This design will make it profitable to service even smaller windfarms, and we see a potential to deliver many designs to this segment. Havyard Design & Solutions, in cooperation with ESVAGT, is once again among the first to launch a new idea, and we believe that this will give us a good head start in relation to our competitors in this market,' concludes Senior Vice President Sales Gisle Vinjevoll Thrane.

Good cooperation
Havyard sold the design and building of the first windfarm service vessels to ESVAGT in July 2013. The ships in question were of the Havyard 832 SOV type, and were delivered by Havyard Ship Technology's shipyard in Leirvik in Sogn during the first quarter this year. The shipyard has an order for another such design for ESVAGT, which is scheduled for delivery in September 2016. In addition, Havyard Design & Solutions has sold a design and equipment package for a Havyard 931 CCV crew change vessel that will be built for ESVAGT at the Spanish shipyard Astilleros Zamakona.
ESVAGT's COO Kristian Ole Jakobsen says that they have developed good and close cooperation with Havyard through the delivered projects and ongoing collaborative projects. 'ESVAGT has extensive experience of operating offshore vessels, particularly specialised standby vessels,' says Jakobsen. 'Our primary focus is on delivering safe and efficient support services for our clients. We have now used this experience and expertise to establish a position for ourselves in the market for service vessels for offshore windfarms. By combining operating expertise with Havyard's expertise in designing and building state-of-the-art vessels, we can deliver service vessels that give our customers an effective and safe platform for servicing their windmills.'
'We are very satisfied with our cooperation with Havyard and with the quality of their deliveries. It probably also helps that we are a demanding customer that will only accept the best,' says a smiling Kristian Ole Jakobsen. He also believes that the new design developed in cooperation with Havyard has great potential.

Turkish connections
The Turkish yard Cemre Shipyard will build the Havyard 831 SOV windfarm service vessel for ESVAGT. Havyard knows this shipyard very well, since it has delivered the hulls for more than 30 of the newbuilds Havyard has delivered since 2005. Through these hull deliveries, Havyard has developed close cooperation with Cemre, a cooperation that will continue and develop now that the yard is to build its first Havyard designTM. In recent years, the shipyard has also delivered completed newbuilds for both Norwegian and international customers, including cargo vessels, fishing vessels and seismic support vessels.

Havyard 831 SOV
When developing this design, the emphasis has been on developing an efficient platform for servicing smaller offshore windfarms. The ship has a spacious and comfortable interior with sufficient capacity to accommodate windmill service personnel in addition to the ship's own crew. It has also been designed with good storage capacity for equipment and tools below deck and for containers on deck. The ship is equipped with three small boats that can be launched to transport service personnel to the windmills. The diesel-electric propulsion system that ensures economical and environmentally friendly operation, both in transit and when the ship is in position at the windfarms. The hull has been designed to ensure low fuel consumption and to move in a way that ensures maximum comfort for the crew and service personnel on board. The ship has sufficient fuel capacity etc. for at least 30 days' operation between port calls.
