Cargo Compressor (Screw) · Gas Carrier Cargo Systems
This equipment is commonly found on liquefied natural gas (LNG) and liquefied petroleum gas (LPG) carriers, where it plays a crucial role in the efficient handling and transfer of gas cargo. Designed as a single-screw compressor with variable capacity, the Vilter VSG Screw is part of Emerson's product line. Its single-screw design ensures reliable operation under demanding conditions. However, like any mechanical system, it can encounter common issues such as star-rotor wear, bearing failure, shaft seal leaks, and capacity control malfunctions. To address these potential issues, spare parts are available directly from Vilter (Emerson), though lead times can range from 3 to 8 weeks. It is recommended to keep critical spare parts, including seals and valve inserts, on board to minimize downtime during maintenance or repairs.
