Swire Blue Ocean (SBO) and Siemens Gamesa Renewable Energy (SGRE) have installed a mobile workshop on Pacific Orca’s deck. The vessel remains on a maintenance and service agreement with SGRE until February 2021, servicing wind farms located in the North, Baltic and Irish Seas.

The new workshop is designed to support SGRE’s Heavy Lift team to repair various types of SGRE nacelles directly at the offshore locations. SBO stated this new system makes the repair process much faster, as it prevents the need for trips between the offshore sites and the port for repair of nacelles onshore. This option is also expected to reduce fuel consumption.

The workshop is 10-metres-high, 13-metres-wide and 30-metres-long and weighs 58 tonnes. It has a retractable roof which opens to allow for placement of the nacelle inside for repairs, providing SGRE’s team with a workspace which is protected from the offshore weather conditions. The workshop was originally designed by OSK for SGRE, and SBO’s engineers secured it to the vessel and will remain stable on
Pacific Orca’s deck, especially during rough weather conditions.

“We are glad that we can safely accommodate the workshop on Pacific Orca as it will improve the efficiency of operations. Beyond that, it increases the flexibility of Pacific Orca as a maintenance and service tool. Now, SGRE can repair nacelles directly on site,”
says Ulf Gjendal, Head of Projects, SBO. “Luckily, we managed to find a good timing for the installation and cooperated very efficiently with SGRE to ensure a smooth mobilisation,” he adds.


“In SGRE we are always in pursuit to optimize time when the vessel is at the wind farm, to minimize down time for the turbine and loss of revenue for our customers. Together with SBO we managed to take advantage of a weather standby period and install the workshop – one team spirit and job well done,”
says Jacob Ib, Senior Marine Operations Manager, SGRE.
