Rapid turnaround for Brave Tern at Damen Shiprepair
The ability to carry out a double-quick major crane refit secured the order for Damen Shiprepair Amsterdam. The upgrade means Brave Tern is fully ready to install and maintain the next generation of wind turbines.
Brave Tern, the 132-metre jack-up operated by Fred. Olsen Windcarrier AS, underwent the insertion of a 20-metre section into the main boom of the vessel’s 800-tonne crane, allowing it to reach a height of 120 metres. All crane wires had to be unreeved before the crane boom could be dropped down to rest on a specially constructed support structure. The boom was then cut in two and the new section inserted and secured using flanges. Following the completion of the new boom the wires were re-reeved and a series of load tests conducted before the crane was certified ready for operations; a total of 30 days.
Fast turnaround time
A ‘no compromise’ on quality or attention to detail fast turnaround was required to secure the order at Damen Shiprepair Amsterdam (DSAm). As it turned out, the actual order was only received the day before the vessel arrived at the yard. It was this ability to both initiate and implement projects at exceptionally short notice (plus its reputation for quality and a convenient location) that convinced Fred. Olsen Windcarrier that DSAm was the ideal yard for this refit. This was the first visit by the Brave Tern to DSAm.
The upgrade of the Brave Tern is part of a wider programme by Fred. Olsen Windcarrier to bring both its Jack-Ups up to the standard required to meet the needs of the new generation of 8MW plus wind turbines. It is not only the crane booms that have been extended, the legs on both vessels have also had an additional 14-metres added.
Following the works at DSAm, the Brave Tern is now ready to install the latest, high capacity wind turbine generators such as the 8MW MVOW V164. The vessel can carry four complete units (tower, nacelle and blades) per loadout.
