LNG Fuel Gas Supply Systems (FGSS) Support
WCS provides service, technical support and spare parts for Klinger Westad cryogenic valves installed in LNG Fuel Gas Supply Systems (FGSS).
A large and rapidly growing number of vessels are operating with LNG fuel systems. Many of these systems have been engineered and supplied by major FGSS integrators, with valves and associated spare parts listed in the vessel's technical documentation under the system supplier's part numbers.
However, many of the cryogenic valves installed within these systems are manufactured by Klinger Westad — which means vessel owners and operators do not necessarily need to source replacement seals, spare parts, or valve-related service through the original FGSS system supplier.
WCS can identify the installed Klinger Westad valves and supply the correct spare parts and sealing components directly — providing a technically equivalent and significantly more cost-effective supply route.
Go directly to the valve specialist — extensive LNG cargo valve experience, now supporting LNG fuel systems worldwide.
Our FGSS support includes
- Identification and cross-reference of installed Klinger Westad valves
- Spare parts, seals and sealing components
- Valve inspection and overhaul
- Onboard service
- Technical support and troubleshooting
For vessels where only the FGSS supplier's part numbers are available, WCS can assist in identifying the corresponding Klinger Westad valve and required spare parts.

LNG Fuel Gas Supply Systems spare parts & service — frequently asked questions
Does WCS support LNG Fuel Gas Supply Systems (FGSS) directly?
WCS doesn't manufacture FGSS systems, but many of the cryogenic valves installed inside them are made by Klinger Westad — and WCS supplies service, technical support, and spare parts for those valves directly.
I only have my FGSS supplier's part number — can WCS still help?
Yes. WCS can identify the corresponding Klinger Westad valve and required spare parts from the FGSS supplier's part number or documentation.
Is this cheaper than going through the original FGSS system supplier?
Yes — WCS supplies technically equivalent spare parts and sealing components through a significantly more cost-effective route than sourcing via the original FGSS system supplier.
