Polskie LNG Completes Roof Air Raising Operation (VIDEO)

Polskie LNG , a PGNiG unit, has provided a video on raising the roof of the first liquefied natural gas storage tank in the LNG terminal being built in Świnoujście.

The roof of the LNG storage tank having the capacity of 160 thousand m3 was raised on the airbag, consisting in a controlled change in air pressure generated under the roof dome. The whole operation lasted exactly 188 minutes. The roof was lifted at a speed of approximately 20 cm / min. The total weight of the roof is 600 tonnes, which is comparable with roughly three Boeing 747 aircrafts. Its surface equals the area of more than two “Orlik” football pitches amounting to 4717 sq. m.
