Haskoning supported TM Edison with detailed design review and optimisation of the Princess Elisabeth Island (MOG II) reference design. The work included reviewing technical aspects of the design, developing design iterations to optimise the island configuration, caisson geometries and wave walls for protection against North Sea conditions, and collaborating with TM Edison’s construction and project management teams to reduce material quantities and improve buildability. This design support was described as contributing to TM Edison’s winning bid for the EPCI scope of the Princess Elisabeth Energy Island.
