One of the largest crane vessels in the world arrived in Lerwick Harbour today after working on the Clair Ridge project 75km west of Shetland.
Thialf had been involved in installing “jackets”, or platform legs, at the developing oil field on behalf of BP. Each of the jackets weighs in at roughly 22,000 tonnes and the platform’s “huge capability” was needed to install them.
BP spokesman Matt Taylor told The Shetland Times the vessel was stopping in Lerwick for a crew change and minor repairs before embarking back to the oil field to install the second of the jackets. Thialf is expected to be staying in Lerwick for a week.
The Clair Ridge project which the Thialf is working on is the second phase of development for the Clair oil field, which targets the area to the immediate north of the existing field. BP recently invested £4.5 billion into the development, which could potentially yield 640 million barrels of oil.
Gas and oil produced from the project is set to be taken to the BP oil terminal in Sullom Voe for processing.
The Thialf is home to two 144 metre cranes which tower above the ship. In addition to the cranes, the ship holds 736 berths and is capable of performing numerous tasks within the oil industry – from foundation laying to installing pipelines.
