The tidal range in the Swansea Bay offers the opportunity for large scale hydro-power generation. A man-made lagoon is designed with bund walls which contain hydro turbines in it. Both with incoming (rising) and outgoing (falling) tides electricity is generated.
The Marine Works contract is part of a suite of contracts that is used to design, build and operate the lagoon, and it consists of the following scope:
- The permanent bund wall structure enclosing the lagoon (approx. 9.5 km)
- The temporary cofferdam structure including dewatering
- Reclamation areas within the lagoon
- Associated dredging, reclamation and rock works
