Liquefied Natural Gas (LNG) is stored and transported in tanks as a cryogenic liquid. Due to a variety of processes at the terminal, LNG continuously evaporates at temperatures above its boiling point generating Boil-Off-Gas (BOG).
BOG must be either removed from the process or recovered back into the system to prevent the over pressurisation of plant equipment and ship storage. The quantity of BOG depends on the design and operating conditions of storage tanks and ship’s cargo tanks.
BOG is generated at the terminal through:
OSL has experience in design and engineering of the different options to handle BOG. These include:
We also have experience in the design of BOG system equipment including BOG Compressors, BOG Recondenser Columns, send-out Pumps and flare systems.
At OSL we will apply our Clever Thinking® culture to understand and deliver cost effective solutions to challenges associated with the generation of BOG in LNG transportation and storage, and to optimise the management of BOG produced across the different units throughout the system.
