As many natural gas reserves are located offshore, major Energy companies have started developing LNG plants installed onboard ships. Known as Floating Liquefied Natural Gas (FLNG) facilities, this is where extracted gas is treated and directly liquefied on board and transferred to ocean-going carriers to deliver it, ready to use, to the market.
Prelude, the first FLNG facility, was, at the time of completion, the largest offshore facility in the world, representing a significant engineering challenge for all contributing parties.

We are proud to have contributed our Condensate Polishing Demineralization system, from design, construction, and supply, to commissioning and start-up.

The Condensate Polishing system removes traces of hydrocarbons in the recovered steam condensate, and the Demineralization unit produces ultrapure deionized water.
The mechanical and process designs were influenced by the particularly severe conditions of the installation site: a floating vessel that operates in an area subject to cyclonic events.
Our expert team developed specific construction solutions to be able to respect the process guarantees in the presence of significant wave motion.

The supplied packages were fully modularized to reduce the assembly time of the plants inside the ship’s hull. A considerable challenge consisted of the mechanical design of the structures that had to support the equipment’s weight and ensure stability during lifting, fitting, and operation with an overall weight of 150 tons and the capacity to withstand multidirectional accelerations.
