Sirius Coralius

5800 m3 LNG Bunker and feeder vessel

Sirius Coralius design is made for High grade of operational flexibility for bunkering ship to ship (STS) and trading as traditional Liquefied Natural Gas (LNG) feeder.

The LNG is stored in two insulated cargo tanks of bilobe type, classified by IMO as ”Independent Type C”. Torispherical heads and a design pressure of 4.5 barg are considered. Each tank is equipped by two submerged deep well pumps for easy discharging. The discharge capacity is 4 x 250 m3/h.

The FKAB L8 main fuel is boil-off gas and regasified LNG from the cargo tanks. This will reduce fuel cost when operating the vessel. L8 is also designed to be as energy efficient as possible with amongst other a slender hull, frequency controlled pumps and fans and further 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.
