Dreggen cranes for Shell FLNG

Bergen Group Dreggen has been awarded with deliveries to the world’s largest floating offshore facility; Shell’s FLNG Prelude.

Bergen Group Dreggen was earlier this year awarded with a contract for delivery of 2 large cranes to the Shell FLNG project; Prelude located on the west coast of Australia. The scope of delivery represents one hose handling crane; DK 1650 to be delivered 4th quarter 2014 and one overhead thruster crane to be delivered in 2nd quarter of 2013.

The Hose handling crane is an offshore rated ATEX classified crane with a capacity of 40T at 30m. The thruster crane is an overhead travelling crane with 2 trolleys carrying individual winches of 120T capacity each.

The contract is entered with Samsung Heavy Industries’ Geoje Island ship yards in South Korea. The Samsung ship yard is one of the few yards in the world big enough to construct a facility of the size of Prelude.

Shell took final investment decision on the Prelude FLNG Project on 20 May, 2011. It will start building a floating liquefied natural gas (FLNG) facility to produce and export LNG off the coast of Australia at the site of the gas field.

Once constructed, the facility will be towed to its location, approximately 475 kilometers north-northeast of Broome, Western Australia. The facility will be moored and hooked up to the undersea infrastructure and the whole production system commissioned.

The floating facility will chill natural gas produced at the field to –162°C, shrinking its volume by 600 times so it can be shipped to customers in other parts of the world. Ocean-going carriers will load the LNG as well as other liquid by-products (condensate and LPG) for delivery to market.

The Prelude FLNG facility will be 488m long, 74m wide and will displace around 600,000 tons of water. It will be the largest floating offshore facility in the world.

The Prelude FLNG facility has been designed to withstand the most powerful tropical cyclones. It will remain permanently moored at the location for around 25 years before needing to dock for inspection and overhaul.

The LNG, LPG and condensate produced will be stored in tanks in the hull of the facility. LNG and LPG carriers will moor alongside to offload the products.
