BAM Clough has taken delivery of the new built jack-up “IB-914” and transport barge “IB-924” from COSCO Shipyard in China, earlier this month.
Both units, designed by Gusto MSC, departed China in mid August on their maiden voyage. This is the third Gusto MSC SEA-1250 jack-up built and it is the first design with Tubular legs.
The “IB-914” will be employed for works on the Chevron-operated Wheatstone Project LNG product loading facility and tug berths near Onslow. The contract, awarded to BAM Clough by Bechtel last year, is valued at approximately A$400 million.
Upon arrival to the project location in Australia, the “IB-914” will be used for the construction of an LNG jetty and will be installing the foundations and pre-fab elements.
The new Gusto MSC SEA-1250 design dimension is 46.5m long, 30.3m wide, has a depth of 4.5m and is carrying a 300t pedestal crane. The initial leg length is 55m and can be extended in the future to 65m. The jack-up unit is able to operate in water depths up to 30 m. New in this design is the tubular leg of 2.5m diameter in combination with the “classic” jacking system.
Wheatstone
The Wheatstone onshore foundation project, located at Ashburton North, 7.5 miles (12 kilometers) west of Onslow on the Pilbara Coast, is a joint venture between the Australian subsidiaries of Chevron (operator 73.6%) , Apache (13%), Kuwait Foreign Petroleum Exploration Company (KUFPEC 7%) and Shell (6.4%).
The foundation project will be fed with natural gas from the Wheatstone and Iago fields, which are operated by an Australian subsidiary of Chevron in a joint venture with Shell and represents 80 percent of the plant’s foundation capacity.
The unique Wheatstone hub concept was developed to provide foundation infrastructure for the commercialization of Chevron’s vast natural gas resources as well as a destination for third-party gas. Under the hub concept, Apache and KUFPEC will provide the remaining 20 percent of the natural gas from their Julimar and Brunello fields.
