New turbine installation vessel for A2SEA
Danish offshore wind installation and service solutions provider A2SEA recently announced a repeat order for a second newbuilding turbine installation vessel from COSCO Shipyard Group in China.
With around 20 new turbine installation vessels due to enter the market over the next few years, this recent repeat order from A2SEA is perhaps a sign that the industry is still considering when the installation vessel order pipeline will match anticipated demand from consented and planned windfarm projects. The vessels currently on order, or recently delivered, are predominantly based on jack-up designs, and with a number of DP vessel concepts based on established offshore industry hulls being offered, this thread of the story of development of offshore wind appears yet to be put to bed completely.
A2SEA is now a major player in the offshore wind industry, having experienced steady growth and now 51% owned by DONG Energy and 49% by Siemens Wind Power. This latest order, valued at $155m, is for another installation vessel identical to the Sea Installer, ordered in 2010 and currently under construction at COSCO, with delivery due later this year.
The vessel will be 132m LOA with a breadth of 39m, draft of 5.8m, and have a speed of 12 knots. Deck space of 3,200m2 and a loading capacity of 5,000 tonnes will allow the vessel to transport eight to ten offshore wind turbines (towers, nacelles and blades). Four double hydraulic system jackable legs, with a jacking speed of 0.5m/minute will allow operation in water depths of up to 45m and accommodation will be provided for up to 60 crew and installation personnel. The crane will be larger than that on the Sea Installer. A 900 tonne extended crane will be fitted (100 tonnes more than its predecessor), capable of meeting the demands of developments in the industry that will see larger turbines engineered for offshore use.
The order is seen by A2SEA as an important step towards the further industrialisation of the offshore wind industry to lower the cost of energy. Jens Frederik Hansen, CEO, of A2SEA said “With the fast growing offshore market in the Northern Europe, we can already today see that the demand for vessels for installation will grow dramatically. With the new installation vessel, we are well prepared to meet that demand and strengthen our position as supplier of installation services. It is very important to us that we are able to meet the demand of tomorrow, when the offshore parks along with the size of the turbines are growing in size. With the new vessel we take a big step in continuing to shorten the time of installation and thereby bringing down the cost of energy from offshore wind.”
Length overall: 132m
Crane capacity 900 tonnes
