Understanding the Challenges of LNGC Systems and Boil-off Gas Management
The management of boil-off gas in LNG Carriers (LNGC) is a complex process due to the intricate relationships between cargo aging, consumption, and reliquefaction systems. Predicting the impact of these interrelated systems on cargo condition during voyages can be challenging, hindering accurate performance measurement and tracking. Operations and Technical teams face the task of balancing various factors like shaft speed, reliquefaction rate, fuel mode, and Gas Combustion Unit (GCU) to effectively manage boil-off gas. This becomes even more complex when trying to minimize LNG consumption while meeting specific Estimated Time of Arrival (ETA) and terminal requirements. Suboptimal boil-off gas management can lead to significant financial losses with thousands of dollars in lost LNG cargo per voyage.
