SPONSORS OF EAST OF SCOTLAND
SKANSKA, SMIT MARINE PROJECTS, GRONTMIJ JOINT VENTURE CAPABILITY AND EXPERTISE
The waters around the UK have some of the World’s best natural resources for wind, wave and tidal energy. Over the coming decades, the Offshore Renewable Energy market will grow to develop this potential.
The Skanska, SMIT Marine Projects & Grontmij Joint Venture has been initiated to serve the needs of the UK offshore wind energy market and brings together significant capability and expertise in construction, marine installation and offshore wind engineering.
COLLABORATIVE AND HOLISTIC APPROACH
They have adopted a collaborative and holistic approach in developing an efficient and economic concept design for a concrete gravity foundation (CGF), which is aligned with the requirements of the construction and installation teams and flexible for use in all areas in water depths from 30-60m, over a wide range of soil conditions and turbine loadings.
COST REDUCTION
Costs have been reduced through applying mass production principles using proven construction techniques and adopting a float-out-and-submerge strategy which, allied to operational flexibility through having a large in-house fleet of vessels and no requirement for anything bespoke, takes full advantage of weather windows. The availability of suitable ports on the East Coast of Scotland with close proximity to the sites and access to good local labour, materials and supply chain is another major factor in reducing costs.
RIGOROUS PROCESS
The design has been subjected to a rigorous process of analysis, simulation and risk assessment involving industry experts from all relevant disciplines resulting in a high degree of confidence in the viability of the CGF concept.
CGF ADVANTAGES
The CGF enjoys a great many environmental advantages over other

foundation types. No piling or other works that might cause noise and vibration to disturb sea mammals is required.
Concrete is an inherently durable material with good resistance to wind and wave fatigue loading, which conveys many benefits including reduced maintenance. Finally, the CGF can be fully decommissioned returning the seabed to its original condition and all materials used during construction can then be recycled.
