Quad lift for Hinkley Point

Detailed multi-body (3) heavy lift analysis involving a quad-crane-lift operation and fully coupled mooring response in extremely shallow water and high current conditions.

As a part of the cooling system of a nuclear power plant; large concrete intake and outfall heads had to be installed on the seabed. The lift was performed by Scaldis with the Rambiz and Gulliver heavy lift vessels. Both equipped with two cranes, using all four cranes to perform a quad lift operation.

A total of 26,000 tons was installed within tolerances of centimeters under the challenging tidal range and currents of the Bristol Channel. Mocean performed extensive mooring and lifting analyses of this operation to ensure a safe installation of these critical components.
