ESVAGT to service the Dudgeon Offshore Wind Farm

Press release   •   Oct 06, 2015 12:00 CEST

Norwegian Havyard Ship Technology has designed the vessel. The hull will be built in Gdansk at the Nauta Shipyard and will be ready to tow to Leirvik in Norway for outfitting in January 2016.

From autumn 2016, a new ESVAGT SOV will be servicing the Dudgeon Offshore Wind Farm in the English sector. The vessel has been ordered from Havyard.

ESVAGT continues to consolidate its activities in the offshore wind energy market. The latest addition is the agreement made between the Statoil Dudgeon consortium and ESVAGT for the delivery of an SOV vessel to service the Dudgeon Wind Farm off Great Yarmouth in the English sector. Delivery is due to take place in September 2016.

The vessel will basically be the same Havyard design as the “Esvagt Froude” and the “Esvagt Faraday”, ESVAGT’s two other purpose built wind service operation vessels (SOV) that provide service for Siemens at the offshore wind farms, Baltic 2 and Butendiek.

”Our experience and our customers’ feedback from our start with the “Esvagt Froude” and the “Esvagt Faraday” have shown that both vessels live up to our expectations in full,” says Kristian Ole Jakobsen, Chief Operating Officer for ESVAGT:

“Design-wise we are in line with the original vessels. The changes that are to be made on the new SOV are partly to meet the specific requirements of the customer and partly to adjust and improve on a few minor areas, based on the practical experience we have now gained with the SOVs.” He says.

Changes and adjustments

Among the changes on the new SOV compared to the original is the introduction of a gangway system from an alternative manufacturer. The Ampelmann gangway system on board the other SOVs have been very successful but for the new SOV, the Norwegian manufacturer, UpTime, has been chosen. The position has also been moved to the starboard side of the vessel.

The home port of Great Yarmouth has no cranes that can lift containers from the quayside to the vessel, so this has to be done by the vessel itself. The new vessel will therefore be fitted with a crane at its aft that can lift 24 tons.

Other adjustments include increasing the hydraulic lift/elevator from 1T to 2T, increasing the AHC winch from 1T to 2T, placing an additional traversing crane on the M-deck, making a 5m draught possible under special loading conditions and increasing the capacity of the bow thrusters from 2 x 800 kW to 2 x 1000 kW.

The number of cabins will also be altered. The new vessel will have 58 single cabins with bath/toilet instead of the 60 on the “Esvagt Froude” and the “Esvagt Faraday”.
