Drydocks World completes largest turret mooring system
Drydocks World has successfully completed the world’s largest turret mooring system for SBM Offshore, Technip and Shell.
At almost 100m high and weighing more than 11,000 tons, the 26m diameter turret will ensure the Prelude floating liquefied natural gas (FLNG) facility can operate safely in the most extreme weather conditions.
Prelude is the world's first floating liquefied natural gas plant as well as the largest offshore facility ever constructed. She will be used in the Prelude and Concerto gas fields in the Browse LNG Basin, 108 nautical miles off the coast of Australia.
Drilling and gas production are expected to begin in 2016 and she is being built in South Korea with a planned life expectancy of 25 years. She is one of the largest vessels are built, with a full-load displacement five times that of a Nimitz-class aircraft carrier.
The turret mooring system for the massive 300,000-gross ton (unladen) vessel was built over the course of 5-million man-hours without any lost time injury (LTI), underscoring “Drydocks World’s position as a leader in turret fabrication”, the company said in a release.
Drydocks World has delivered 5 modules for the Shell FLNG turret mooring system with delivery of module 5 representing the completion of the project, with the turret being the heart of Prelude FLNG.
Prelude FLNG is a truly global project, with her turret mooring system alone having been designed in Monaco, constructed in Dubai, and shipped to South Korea for use off Australia.
