Sarens lifts for BiFab

July 13 - Sarens has transported an offshore wind farm jacket for Burntisland Fabrications (BiFab) in Methil, Scotland.

The offshore wind farm jacket, which weighed over 1,000 tonnes, was transported 76 m using 60 axle lines of self-propelled modular transporters (SPMT) and six power pack units.

Once the offshore jacket was in the horizontal position at the up-ending location, the Sarens team attached the lifting tackle to the lifting points and removed the lashing so that two main lift cranes - a Demag CC9800 and CC8800-1 - could begin hoisting the jacket for the 90 m lift.

With the main lift cranes in operation, tail cranes then began to hoist, slew and track towards the main lift cranes.

As the offshore jacket became more vertical and the load was transferred onto the main lift cranes, the tail cranes began to slew the offshore jacket into its final position until the load was shared between the main lift cranes.

"The greatest challenge during the lifting operation was to coordinate the functioning of the two main lift cranes and two tail cranes," explains operations manager Andrew Hunt.

BiFab is manufacturing 26 jacket substructures for the Beatrice offshore wind farm in the North Sea, located off the coast of Scotland. As part of its contract with engineering, procurement, construction and installation (EPCI) contractor Subsea 7 and its subsidiary Seaway Heavy Lifting, BiFab will deliver the first ten substructures this August and the remainder in April, 2018.
