LNG bunker vessels are used for refueling LNG-powered vessels at sea. Since gas evaporates continuously from the LNG, the tank pressure increases and must be controlled within the tank design pressure specifications. Burckhardt Compression’s Marine Compressor solutions offer easy and efficient BOG handling while dealing with limited space.

Marine Compressor Solutions for LNG Bunker Vessels

Burckhardt Compression’s Marine Compressor solutions are used to deliver up to 350 bara injection pressure to dual-fuel engines that operate in the Diesel-cycle. The Marine Compressor can deliver up to 20 bara to dual fuel engines that operate in the Otto-cycle. Side streams at each stage allow multi-purpose compression feeding e.g. auxiliary engines or (if applicable) re-liquefaction processes.

The compact design offers the chance to install redundant compressors even if space is very limited. The compressor solutions are designed for easy service that allows the on board crew to do the service. The lubricated Marine Compressors offer longest mean time between overhaul (MTBO). Included oil filtration units maintain the fuel gas quality at a high level to help the operator to meet the exhaust gas emission requirements.
