The Client’s Energy Island project aims at developing and building new grid infrastructure, including offshore transmission infrastructure and cables, in the Belgian part of the North Sea. The project purpose is to create an energy hub – in the form of an artificial island – not only to provide an efficient, reliable means of connecting new Belgian offshore power to the mainland, but also to make optimal use of the power production areas in other parts of the North Sea by accommodating a connection point for (hybrid) interconnectors.
CDR has been assigned to prepare the Island Reference design for tendering purposes.
CDR International has been responsible for the preparation of the reference design for tender of the artificial island. These works included:

  • the specification of the functional- and performance requirements,
  • global hydraulic safety assessment,
  • island layout design, location assessment and dredging designs,
  • the design of marine protective structures (caisson-type Seawall, Breakwaters),
  • scour protection design, and
  • supervision of 2D physical model testing for overtopping and wave force measurements.

The artificial island design consists of a sheltered harbour, a caisson perimeter protection with parapet seawall, drainage system for (overtopping) water, reclamation, scour protection and dredging.
