Swire Blue Ocean has started work under a maintenance and service agreement with Siemens Gamesa Renewable Energy. The agreement runs until February 2021 and covers windfarms in the North, Baltic and Irish Seas
Pacific Orca was mobilised on 24 June 2019 to Meerwind Süd/Ost offshore windfarm, off the north-western coast of Germany, and Galloper offshore windfarm, off the south-eastern coast of England, where wind turbines were originally installed by SBO.
Visits to Sandbank windfarm and three other windfarms are already scheduled, with other sites following.
SBO chief executive officer Mikkel Gleerup said, “This is our largest maintenance and service venture to date, and we are delighted to partner with SGRE on this project. We are building on extensive experience in wind turbine installation and are reinforcing our expertise in maintenance and service to better respond to our customer’s needs. We are more than ever prepared for further development within the O&M market.”
Pacific Orca was suited to undertaking the contract servicing different types of turbines without any need for modification. With its large cargo area and high capacity deck loading, the vessel provides considerable flexibility and availability. Mobilisation time can be reduced from 12 hours to three or four hours, if required.
The vessel is fitted with six legs to increase jacked stability and a high-redundancy diesel-electric power system to reduce the risk of breakdown.
Some of the sea fastening equipment used on the Beatrice offshore windfarm project is being reused on the project. Since the Beatrice components are the largest expected during the service agreement it was possible to slightly modify and reposition the sea fastening, enabling the embarkation of larger and smaller parts. It is not always possible to reuse sea fastening from a previous project, but doing so enables cost savings, especially as most sea fastening is produced with an operational life of around 15 years.
