Oil-free high-pressure gas supply to MAN B&W ME-GI engines and partial reliquefaction system. Your benefits Completely oil-free gas compression No need for cylinder lubrication, no risk of oil carry-over to cargo and equipment. Gastight No loss of cargo to atmosphere as all piston rod packing leakages are contained and recycled within the compressor system. Zero venting All gas will be routed back to the cargo tanks when stopping the compressor – no venting of gas to atmosphere during stop and emergency conditions. Smooth operation Simultaneous gas supply to main engine, dual fuel generators and reliquefaction system. Proven technology More than 2 million operating hours at sea. Proven reliability Documented product availability proving reliability above 98%. Highest availability Well established marine service network. Features Multi-stage gas compression Cryogenic design on 1st stage: Labyrinth sealing technology (design temperature -160°C) Dry-running ring sealing systems for higher stages Redura® sealing solutions In-house developed and produced Persisto® materials for oil-free, dry-running gas compression up to 350 bar Lowest vibrations The fully balanced crankgear ensures perfectly balanced forces and moments protecting the ship's structure Environmentally friendly Mechanical shaft seal enables gastight crankgear Tailored solutions 300 bar fuel gas supply and BOG handling systems for LNG carriers with ME-GI propulsion MSO compressor and BOG handling systems for Floating Storage and Regasification Unit (FSRU/FSU) Standardized skid mounted compressor packages Technical data Standard packages for LNG carriers with ME-GI (discharge pressure 300 bar) 5-stage gas compression Rated power kW *Typical mass flow kg / h l x w x h m 4LP250V 1'500 3'100 11.5 x 7 x 5.5 5LP250V 1'950 5'000 11.5 x 7 x 5.5 6LP250V 2'300 5'700 11.5 x 7 x 5.5 *Suction capacity at gas inlet temperature +20°C For FSRU / FSU (discharge pressure 30 – 110 bar).

Contact us Downloads Laby®-GI compressor brochure EN pdf 5.38MB More languages No other languages available Technologies Labyrinth sealing Ring sealing system 100% Mass balancing Labyrinth sealing In the piston and piston rod gland many tiny throttling points create a friction-less sealing effect. The avoidance of mechanical friction and the contactless cylinder results in an extremely long lifetime of sealing components with unmatched reliability and availability. Resulting benefits No mechanical wear due to contactless seals For cryogenic gas suction temperatures without pre-heating of the gas nor pre-coaling of the compressor Suitable for oil-free compression Enables longest lifetime Lowest maintenance costs Ring sealing system Redura® sealing system These patented ring sealing systems are successfully applied in a wide range of applications. The vertical alignment of the Laby ® -GI compressor provides low wear of the sealing and guiding elements on the piston and the piston rod. Leading to highest durability of these wear parts. In-house tribology research and the use of latest material technology result in high pressure sealing elements designed for minimum wear and optimized gland performance - as proven in our test facility. Resulting benefits Dry-running oil-free compression For pressures up to 350 bar Longest lifetime Low maintenance costs 100% Mass balancing 50x less total forces and 5x less free moments The fully balanced crankgear leads to a smooth running compressor. The compressor will not stimulate the connected offshore structure or interfere with the structural analysis of the naval architecture. Vice versa neither roll or pitch nor engine vibration, for example on a LNG carrier, will have the slightest influence on the compressor system and its auxiliaries Resulting benefits no free forces and moments no influence on supporting offshore structure Applications Boil-off-gas onshore Marine Our services offering Agreements Installation and commissioning Training Contact your gas compression expert Unlock efficiency.
