Siemens Gamesa and Swire Blue Ocean have installed a mobile nacelle repair workshop on board Swire’s Pacific Orca jack-up vessel.
Swire said the new addition will speed up repair work on offshore turbines in the Siemens Gamesa fleet, which the vessel is undertaking until February 2021 as part of a charter deal inked last year.
The workshop is 10-metres-high, 13-metres wide, 30-metres-long and weighs 58 tonnes.
It has a retractable roof that opens to allow for placement of the nacelle inside for repairs, providing the Siemens Gamesa team with a protected workspace to fix generators.
The unit was designed by OSK-offshore and complies with onboard safety requirements.
“The workshop on Pacific Orca will improve the efficiency of operations. Beyond that, it increases the flexibility of Pacific Orca as a maintenance and service tool,” said Swire head of projects Ulf Gjendal.
The unit was added to the vessel last month amid weather downtime.
“We are always trying 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,” added senior marine operations manager at Siemens Gamesa Jacob Ib.
