On 6 June 2014, Scaldis Marine Contractors NV, under contract to Wintershall Noordzee B.V., conducted a heavy lift and installation operation utilizing their HLV Rambiz, a self-propelled crane barge.
Scaldis notes the installiont of the L6-B platform was particularly tricky as it involved a dual crane lift while attached below the center of gravity of the structure.
Utilizing a special tool to enclose the platform mast, the lift was successful and the platform was subsequently installed at block L6 25 nm northwest of Terschelling in the Dutch sector of the North Sea in 35 meters of water.
Suction piles were used to secure the platform to the seabed and were sunk to a depth of 10 meters below the mud line.
