On Sunday the 9th of September the last of the four export cables of the London Array Offshore Windfarm project has been landed ashore successfully by the marine department of VSMC. During each shore landing the CLV Stemat Spirit was positioned in the Swale, over a mile away from the duct entry underneath the sea defence wall. Local conditions (such as hardly accessible mudflats, an ultra shallow section near the beach with just 80 cm of water during high tide and over 3 knots currents during spring tides) demanded a highly engineered solution to bring the cables successfully ashore. Each shore pull required 2,5 km of cable to be made a float, using seaserpent as buoyancy device. A midsupport pontoon with a chute was used to reduce forces during the floating sessions and to position the cable accurately during the sinking. Alongside the regular crew of the Stemat Spirit 33 people were involved in the operation from different parties.
It is to be highlighted that excellent co-operation with crew and staff from VolkerInfra and VSHanab cable department has contributed significantly to the success of the shore pulls.
