Tidal Lagoon (Swansea Bay) has selected China Harbour Engineering (CHEC) as the preferred bidder for marine works contract for the £1bn tidal lagoon project in Swansea Bay, Wales, UK.

Tidal Lagoon (Swansea Bay) is a special purpose vehicle company launched to build, own and operate the 320MW tidal lagoon facility with an operational life of 120 years.

Under the £300m contract, CHEC will construct the bund wall and coffer dam, sourcing and transporting rock armor and materials.

The company will invest approximately half of the contract amount on a British workforce, local partners and a local supply chain.

For the main marine work at Swansea Bay, a fixed-price contract will be signed in near future with a risk and value engineering scheme, upon completing advanced works.

A UK subsidiary has also been launched by CHEC to manage investment infrastructure opportunities over the next decade.

CHEC president and CEO LIN Yi Chong said: "We will seek to grow our UK presence through significant investment into a subsidiary business and through a program of UK infrastructure investment and construction."

CHEC will also sign a memorandum of understanding with Tidal Lagoon Power to explore tidal lagoon projects in Asia and particularly along China’s coastline.

Tidal Lagoon Power engineering and construction director Andrew McNaughton said: "Tidal Lagoon Power’s vision is to create a new domestic industry, stimulating UK employment, GDP growth and future exports."

Tenders will be issued by Tidal Lagoon Swansea Bay through the summer for the construction of a Turbine Assembly Plant in Wales, and for the lagoon’s public realm and buildings work.
