VIDEO: Shell completes mooring for Prelude FLNG

Video chronicles efforts to secure largest floating facility ever built after its arrival in Australia

Anglo-Dutch supermajor Shell has shared a video documenting the mooring of its Prelude floating liquefied natural gas facility in the Browse basin off western Australia.

The giant vessel - touted as the largest floating facility ever built - arrived on site in late July after completing its 6000-kilometre journey from Samsung Heavy Industries' Geoje yard in South Korea. Construction began in 2012.

The vessel measuring 489 metres in length and 74 metres wide, with a dry weight of 256,000 tonnes. The weight will be 660,000 tonnes when fully loaded, according to the video.

Boasting "one of the strongest mooring systems ever built", Prelude will be attached to mooring piles embedded in the sea floor with 25,000-link chains, said to be one of the longest chains in the world.

The next step will be hooking up and commissioning the production system, which is expected to take between nine amd 12 months.

The vessel has total processing capacity of 5.3 million tonnes per annum, including 3.6 million tpa of LNG, 1.3 million tpa of condensate, and 400,000 tpa of liquefied petroleum gas. It is expected to have a life of 25 years.

Shell operates Prelude with a 67.5% stake and is partnered by Japan's Inpex on 17.5%, Taiwan's CPC on 5% and South Korea's Korea Gas Corporation on 10%.
