Sheringham Shoal Offshore Windfarm

Cable Route Development

The Project

The work carried out on this project was part of a larger project with total costs of €110m. OceanIQ® and Visser and Smit formed a Joint Venture to install the export and array cables at Sheringham Shoal, an element of this service was to design and engineer the final cable routes.

90% of this cable route development work was carried out by OceanIQ® and involved an understanding of the installation and engineering required to protect the cable, maximisation of cable burial and installation methodologies required for this shallow water site and wind turbine foundation connections.

OceanIQ® provided final route position lists (RPLs), cable length calculations including HDD ducting sections and interfacing with all other package contractors, UXO avoidance and archaeologically significant area avoidance. Reporting was provided on the route development and routing rationale and criteria.

The export cables were 132kV (AC) Cu XLPE and array cables were 33kV (AC) Cu XLPE, supplied by Nexans.

Determining reliable cable ampacities for marine high voltage cables.

Determining reliable cable ampacities for marine High Voltage Cables is currently the subject of significant industry and academic reassessment in order to optimise the operation (ampacity), design (cross-sectional area) and subsequent efficiency, longevity, CAPEX and profitability of both submarine power cables and their dependencies (Enescu et...
