FLNG WATER INTAKE

RISERS

Floating Liquefied Natural Gas (FLNG) units require large volumes of seawater to boost the gas liquefaction process efficiency. In order to reach seawater sufficiently cold enough, seawater intake risers are utilised ; which are typically 120 - 300m long and designed for a minimum life service of 25 years.

GMC’s weldable connector material permits high strength and fatigue resistant large OD joints to be prefabricated in an onshore workshop, then clicked together safely and quickly offshore into full Water Intake Risers (WIRs).

Assembling WIRs offshore with GMC’s patented fatigue resistant connectors and 100% shop controlled welding, guarantees the maximum level of reliability and reduces offshore construction time.

Based on modern analysis techniques, GMC’s Water Intake Riser design is highly optimised to reduce stress concentrations and improve performance in both stand-alone and bundled configurations.

GMC’s WIR Connector is guaranteed to beat the competition on performance, price, and delivery lead times.

The GMC Connectors used for Water Intake Riser applications provide the following benefits:

• Non-Rotational Make-Up• Low Connection Make-Up Time• Retrievable for Maintenance and Inspection• Reusable Connections• Suitable for Large Diameter Applications (48”+)• No Elastomers (Multiple Metal -to-Metal Seals)• Manufactured from Corrosion Resistant Alloys• Extremely Fatigue Resistant

(10 X Better Fatigue Life Versus Welded WIRs)• Field Proven in High Load, High Fatigue

Applications• HDPE or Steel

GMC Water Intake Riser (WIR) offerings expand to

the provisions of a complete installation service

suited to your requirements.

GMC understands that the design and analysis of the

handling / make-up tooling is equally as important

as on the risers themselves. We employ the best

engineers and designers to offer conventional and

customised tooling that provides a safe, efficient,

and cost effective installation.

From stand-alone hang off tables, spiders, and make/

break tools, GMC also designs and builds complete

combination tooling and equipment that can be

operated from one power source and control panel,

which minimises footprint, saves space, as well as,

increases safety and efficiency.
