Subsea gas link planned for western Denmark

The Danish Energinet Gas-TSO has contracted Royal Boskalis Westminster to lay a new four-kilometre (2.5-mile), 36-inch subsea gas pipeline from Jutland in western Denmark to the island of Funen.

Boskalis’ work scope includes pre-trenching, pipe-pull, cofferdam construction and post-lay rock installation to protect the pipeline. In addition, the company will apply a guiding roller system to ensure a bend in the pipeline, as stipulated in the contract.

The programme will require a trailing suction hopper dredger, fall-pipe vessel and backhoe dredger.

Boskalis has also won an order to provide scour protection of the turbine foundations of the Yunneng wind farm offshore Taiwan, on behalf of Yunneng Wind Power Company.

This will involve installing rock on the sea floor around 71 monopile foundations serving as scour protection. Local quarries in Taiwan will supply a total of 325,000 tons of rock which Boskalis will install using a fall-pipe vessel.

All work should be completed late next year.
