Prelude FLNG

Oil and gas company Shell has selected Emerson Network Power as the main uninterruptible power supply (UPS) systems provider for the company’s Prelude floating liquefied natural gas (FLNG) project.

The FLNG project is under construction in Korea at present for deployment to the Browse basin off the coast of Western Australia.

Emerson will help provide standby power for critical process functions, such as the main automation systems, fire and gas detection systems, as well as telecommunications.

Emerson has awarded a contract worth around €1m to Alcad to design, manufacture and supply eight large battery systems, featuring ultra low-maintenance nickel-based technology to provide the power.

The battery systems consist of Alcad cells and will be installed in four battery rooms on the floating facility to provide power for the main automation systems, fire and gas detection systems, telecommunications and emergency lighting.

Designed to ensure total reliability in the exacting industrial applications, such as found in the offshore oil and gas industry, the batteries will provide between 60 minutes to four hours of autonomous operation, in the event of a loss of power from the main generators.

"The company’s chloride industrial-grade UPS systems have been designed to supply backup power in the demanding environments for a lifetime of more than 20 years."

The Alcad cells also feature an ultra low-maintenance design with controlled gas recombination and a valve regulated venting system, and feature a compact design enabling the battery systems to offer a high-power and energy capacity within a small installation footprint.

According to Emerson, the company’s chloride industrial-grade UPS systems have been designed to supply backup power in the demanding environments for a lifetime of more than 20 years.

Emerson Network Power business leader Scott Barbour said mission-critical facilities on the FLNG facility require the highest levels of availability, and to make sure infrastructure remains always-on, backup power supplies serve as key components.

"This is a great opportunity for us to join our colleagues at Emerson Process Management to put some of our best solutions and services into practice, in an extraordinary application," Barbour said.
