Laby-GI BOG Compressor

Burckhardt Compression Laby-GI ist der de-facto-Standard für BOG-Kompressoren auf LNG-Carriern. Der Labyrinth-Kolben-Kompressor verdichtet das Boil-Off Gas (BOG) aus den LNG-Tanks ölfrei und speist es in das Schiffsantriebs-System (Reliquefaction oder als Treibstoff für den Dual-Fuel-Motor). Burckhardt hat geschätzt 60-70% Marktanteil bei LNG-Carrier BOG-Kompressoren.
