Wärtsilä Cargo Handling for small LNG Carriers

There is a growing demand for small-scale transportation of LNG to end users that are located in areas where pipelines are not feasible or economically viable. Typically, such end users are power generation plants, land based industries, and suppliers of LNG as fuel for vehicles or ships. Wärtsilä has developed a Cargo Handling System, the design of which is based on the extensive experience that Wärtsilä Gas Solutions has accumulated in delivering such systems for LPG, LEG and LNG carriers. The available scope includes: 

  • Cargo handling system
  • Boil-off gas handling
  • Cargo tank design and complete tank delivery
  • Ship design
  • LNG fuel supply system

We provide designs for small size LNG Carriers carrying LNG only, or Multi Gas Carriers able to carry all types of gas cargo. Typically these ships are between 4 000 and 40 000 m3.

    Applications
    LNGC Shuttle Tanker

    LNG Shuttle Tanker

    Shuttle tankers for LNG are used to transport LNG to remote hubs and small scale import terminals. The typical size of these tankers is up to 40 000 m3.
    LNGC Bunkering Vessel

    LNG Bunkering Vessel

    LNG bunkering vessels are used for ship to ship bunkering operations in line with the increasing use of LNG as a marine fuel. The typical size of these vessels is up to 10 000 m3.
    LNG Barges

    LNG Barges

    Wärtsilä Gas Solutions can provide complete cargo handling systems for LNG barges, as well as the complete ship design package for such LNG barges.

    These barges can be built solely for transport/bunkering, or can also be equipped with Wärtsilä LNG Liquefaction, LNG Regasification, or fully integrated LNG power systems.

    Technical Data – Small-Scale Reliquefaction

    In addition to the complete cargo handling system design, Wärtsilä also offers a newly developed reliquefaction plant for seamless integration, suitable for the small-scale segment. The system offers cost-efficient reliquefaction of LNG boil-off and is modularized and scalable to cover a wide range of capacities and vessel sizes. The system is based on well-proved Brayton-technology and designed for competitive OPEX, ease of operation and minimal maintenance.
