Three Swire Pacific Offshore (“SPO”) vessels have been assisting with the installation of foundations for 20 wind turbines off the coast of western Taiwan region, where construction of a 120-megawatt offshore wind farm kicked off in May and is expected to be completed by the end of the year. Pacific Warlock and Pacific Valkyrie have been chartered by Seaway Heavy Lifting to carry out anchor handling duties for the heavy-lift vessel, Seaway Yudin, while Pacific Liberty’s role is to deploy a ‘bubble curtain’ at the construction site. The pile-driving involved in installing turbine foundations results in significant underwater noise pollution, which can prove harmful to marine mammals, such as the endangered white dolphin. To mitigate this effect, each foundation site is encircled by a perforated tube filled with compressed air, which rises toward the surface, forming a circular wall of bubbles that contains the noise source. The project is a testament to the calibre of Swire Pacific Offshore’s vessels and their crews, who are playing a critical role in the inception of Northeast Asia’s renewable energy industry.
