Alfred Tennyson wrote:We are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.

Pieter Schelte is a platform installation/decommissioning and pipelay vessel built for the Allseas company, which is the world's largest.[1] The main construction is underway at Daewoo shipyard, Korea and final completion will be in The Netherlands. Main diesel power comprises eight MAN 11,2 MW engines with two engines each in four separate engine rooms[2] with 13 Rolls Royce 5.5 MW thrusters.[3] The vessel was designed by engineering company Deltamarin. Allseas¹ has committed to build Pieter Schelte at a cost of US$1.7 billion. It will be 382 metres (1,253 ft) long and 117 m (384 ft) wide.
Progress: Long-lead items, such as the power generation equipment and the thrusters, were ordered in March 2007.[4] In June 2008 the high-tensile steel for the jacket and topsides lift systems was ordered.[5] The hydraulic cylinders were installed by Apex Hydraulics on the A&R Winch reacting to a 480 bar test pressure.[6] According to Allseas, the conceptual design of Pieter Schelte and the basic design of the novel twin hulls was completed by Swan Hunter in Newcastle-upon-Tyne, England. The basic design of the lifting systems was completed by the end of 2008 and detail design of the hulls by May 2010.[7] In June 2010 the main construction contract was signed with South Korean shipyard Daewoo Shipbuilding & Marine Engineering Co Ltd at Geoje.[7]
In 2013 the hull was launched at Daewoo and is due for completion in late-2014 in the Alexiahaven, Maasvlakte 2, Port of Rotterdam.[8]

Prelude FLNG is the world's first floating liquefied natural gas platform as well as the largest offshore facility ever constructed. The Prelude is being built by Samsung Heavy Industries and Technip in South Korea for Royal Dutch Shell.[1] It is 488 metres (1,601 ft) long, 74 metres (243 ft) wide, and made with more than 260,000 tonnes of steel.[2] In operation, it would weigh more than 600,000 tonnes; more than five times the weight of the largest aircraft carrier.[3]
The hull was launched in December 2013.[4]

Operations
The Prelude FLNG system will be used in the Prelude and Concerto gas fields in the Browse LNG Basin,[5] 200 km off the coast of Australia; drilling is expected to begin in 2016.[4] and have a planned life expectancy of 25 years.[6]
Natural gas will be extracted from wells and liquified (by chilling it to –162°C). The ability to produce and offload LNG to large LNG carriers is an important innovation, which reduces costs and removes the need for long pipelines to land-based LNG processing plants. However, fitting all the equipment onto a single floating facility was a big challenge.
The system is designed to withstand Category 5 cyclones. It will produce 110,000 BOE per day.
The project is a joint venture with KOGAS and Inpex.[7]
