The economic transportation of large quantities of Natural Gas from the producer to the customer can be achieved either by use of gas pipeline or, with the gas in a liquefied state, by ship (LNG tanker). For LNG ship transportation, a cryogenic receiving terminal is required at the port of destination. Huge installations are required for the safe and economic storage and handling of the LNG and the associated boil-off gases created during unloading and storage.

The technical features of these terminals, like those aboard the LNG tankers themselves, are fascinating in terms of both dimensions and the art of engineering. Safe and environment-conscious handling of the cargo, prevention of leaks, exposure of materials to cryogenic temperatures and bone dry gas, as well as rapid temperature changes, are of high concern to the designers. Among the rotating equipment used in this field are reciprocating compressors.

This paper presents the design features of Labyrinth-Piston Compressors specially designed for:
- Recovering LNG boil-off gas vapour in receiving terminals.
- Design and material selection of compressor parts exposed to cryogenic temperatures.
- Start-up and cool-down procedures with Labyrinth-Piston Compressors.
- Flexible capacity control for different flow requirements during ship unloading and storage.
- Operating experience and maintenance reports after periods of remarkable running hours.
