LNG feeder vessel
The FKAB L2 design is tailor made for regional distribution of Liquefied Natural Gas (LNG). The LNG is stored in three insulated cargo tanks of bilobe type, classified by IMO as ”Independent Type C”. They have spherical heads and a design pressure of 4.1 barg. Each tank is equipped by two submerged deep well pumps for easy discharging. The discharge capacity is 6 x 300 m3/h.
The FKAB L2 main fuel is boil-off gas and regasified LNG from the cargo tanks. This will reduce fuel cost when operating the vessel. Despite this the L2 is designed to be as energy efficient as possible with amongst other a slender hull and a heat recovery system. These measures reduce costs further but will also reduce the environmental footprint of the vessel. To maintain flexibility and for emergency use the machinery is of dual fuel type and the vessel has capacity to carry MGO as fuel also.
