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.
More and more merchant ships that are fueled by liquefied natural gas (LNG) enter the market. LNG tanks of different sizes are installed on those ships depending on the operation profile that these ships are designed for.
Reciprocating compressor solutions offer best in class fuel gas control due to the insensitivity of this technology to dynamic suction or discharge pressure and mass flow changes, gas temperatures and gas composition. The Laby®-GI Compressor fuel gas solution on top of that maximizes the operation flexibility due to the use of temperature insensitive, contactless and oil-free labyrinth sealed first compressor stages, eliminating the need for gas pre-heating or compressor pre-cooling. This enables the operators to immediately startup the compressor when needed.
Floating storage and regasification units (FSRU) are in many cases the most economical way of adding storage and re-gasification capacity to the local gas supply. Depending on the size of the tanks, the load level of the liquefied natural gas (LNG), the ambient temperature and the quality of the LNG tank insulation the amount of boil-off gas (BOG) per hour changes.
