Video: Shell completes Prelude subsea structures installation

LNG giant Shell informed that as its Prelude FLNG facility is being built at Samsung Heavy Industries’ Geoje in South Korea, the project’s development has moved to the seabed at the Prelude gas field off Australia.

In a recent video update, Shell reveals the work has been completed on the subsea network that will control the flow of gas, consisting of christmas trees, manifolds and flow lines that will all be connected to anchor piles, 200 kilometres (around 125 miles) off Australia’s north-west coast.

Once the construction of the systems has been completed, the construction vessel North Sea Atlantic set sail for the Prelude gas field on February 8 where the installation of the systems began.

The campaign of positioning the anchor piles, installing Prelude’s manifolds, setting the christmas trees on wellheads 250 meters bellow surface has been completed within 21 days by the contractor Technip.

Once the Prelude FLNG facility arrives at the gas field it will be connected to the subsea system and when in operation, the Prelude FLNG facility will produce at least 5.3 million tonnes (mtpa) per annum of liquids: 3.6 mtpa of LNG, 1.3 mtpa of condensate (equivalent to 35,000 bbl/d) and 0.4 mtpa of liquefied petroleum gas (LPG).
