Sheringham Shoal
The Sheringham Shoal Offshore Wind Farm is a large-scale wind project located off the coast of Norfolk in the UK. It consists of 88 offshore wind turbines and is known for being one of the earlier major offshore wind developments in the region.
Semar supported the Sheringham Shoal Offshore Wind Farm development through detailed engineering, feasibility studies and structural design work related to the installation of the 88 offshore wind turbines. Our involvement included both design-office engineering and close follow-up of marine operational planning.
The project contributed to building Semar’s long-standing competence in offshore wind installation engineering. The work strengthened our portfolio in:
Structural and mechanical design
Sea fastening and heavy‑lift preparation
Turbine transport & installation planning
Offshore wind construction methodology
The experience from Sheringham Shoal continues to support Semar’s role as a trusted partner in offshore renewable energy projects.
Installation vessel “Nora” loaded with 8 wind turbine generators
Scope of work summary
- Planning and design of deck layouts for transportation and installation of all 88 wind turbines
- Feasibility studies for turbine installation methods and deck configurations
- Design of support structures for 24 wind turbine blades
- Design and strength calculations for sea fastening grillage for transportation and installation of two offshore substation platforms
- Design of Container grillage used for securing 5–14 containers, depending on operational phase
- An access platform for a telescopic gangway intended for safe personnel transfer during installation operations
Key figures
Client: Master Marine / Statoil
Operator: Statoil
Project duration: 2008-2011
Project characteristics: Feasability studies, deck layout planning, design of steel structures and design of hydraulic systems.
Construction in Batam.
Our scope in the Sheringham Shoal project was completed and fabricated ready for delivery ex.works Batam on schedule, but due to delay in vessel delivery, the end client Statoil terminated the contract.
In connection with structural design, our Design department delivers comprehensive 3D models and detailed engineering and fabrication drawings.
