Latest event on Nordsee Ost

A fire broke out in the engine room of the wind farm service vessel World Calima whilst it was servicing the Nordsee Ost offshore wind farm. A distress signal was hailed at around 8:20am after the vessels' crew noticed heavy smoke. The fire was controlled with on-board resources by locking the engine room and flooding it with carbon dioxide. Another nearby wind farm service vessel, Windea Two assisted the World Calima, manoeuvring the vessel out of the wind farm to avoid a collision with the turbines. The rescue vessel, HERMANN MARWED arrived at 9.40am to assist. About 15 minutes later, a four-ship NATO naval unit followed. The rescuers determined that German mine-hunting boat Sulzbach-Rosenbergwould stay on the scene to assists with the vessels safe tow to shore. A daughter vessel of the HERMANN MARWEDE transferred the eight wind farm technicians and put them on the sea rescue cruiser. The vessels arrived in Helgoland at 4:45pm and the fire was confirmed to be extinguished. Read more

Comments According to the 2014 draft of the Offshore Network Development Plan, Nordsee Ost will have a grid connection of 288MW to HelWin1 indicating that the wind farm will be overpowered.

The foundations were planned to be delivered from Norway four pieces at a time by a standardised North Sea barge. Storage capacity at load-out harbour Bremerhaven has been secured for 6 months where the foundations can be directly loaded onto the installation vessel.In reality, troubles were had concerning limited space at both the factory in Norway and in Bremerhaven for an extended period of time; the jackets were stored on barges for as long as possible.

RWE also agreed a twelve month storage contract for the array cable at its manufacturing yard in Sweden, and faced challenges when this contract expired yet were not ready to install the cable. The 63km of delicate subsea cable was moved to Landskrona for temporary storage.
