Fuel Gas Injection
Laby® Fuel Gas Compressor Systems for Small WinGD X-DF Powered LNG Carriers and Bunker Ships
Burckhardt Compression offers a variety of compressor solutions for fuel gas compression that have been specifically designed for marine applications. Our X-DF fuel gas compressor systems are designed for BOG management on LNG carriers equipped with WinGD X-DF two-stroke engines.
The well-proven Laby® Compressors offer the most power-efficient solution for fuel gas compression and support the optimization of the ship’s operational costs (OPEX). The oil-free compressor system can supply gen-sets, the propulsion engine and the reliquefaction system. In addition, it can be operated in parallel to the pump vaporizer unit.
