DONG acquires new crew vessel
A new service vessel, is to help DONG Energy reduce the cost of energy from Borkum Riffgrund 1 offshore wind farm in Germany. From 1 March 2015, the company has chartered a new vessel for crew transport at Borkum Riffgrund 1.
"The new vessel, named Wave Craft, has the potential to optimize our operation and maintenance of offshore wind farms and consequently reduce the price of energy from offshore wind. It is not only the availability of our wind turbines that will be increased since the vessel is more stable and less vulnerable to severe weather. We will also be more efficient because the vessel's speed makes it possible for us to reach the turbines much faster than before," says Niels Agner Jensen, Naval Architect and Lead Maritime Project Manager.
Operation and maintenance of offshore wind turbines typically accounts for more than 20 percent of the total investment in an offshore wind farm. One of the reasons is that turbine availability is often challenged by the harsh weather conditions that make it difficult to reach the turbines by boat quickly.
It will be different on Borkum Riffgrund 1 offshore wind farm in the North Sea with the new vessel, which uses a completely new air cushion technology that makes it possible for the technicians to sail to the wind turbines with higher speed, under more difficult weather conditions and in greater comfort.
DONG Energy has chartered the vessel for eight months from March 1, 2015 with the option to extend the contract for an additional four months.
The vessel is 26 meters long, 10 meters wide and has a total payload of four tons. Depending on, among other things wave height, the vessel has a cruising speed of +40 knots and an average range of +500 navy miles and can carry 2-3 crew members and 12 passengers.
The vessel will be tested with special equipment to record and monitor its performance so DONG Energy can compare it with the other vessels used in Borkum Riffgrund 1 offshore wind farm.
