Inpex has announced that the roof of the second LNG cryogenic storage tank for the Ichthys project has been safely lifted at Bladin Point.
Measuring 90 m in span and weighing 1100 t, the steel structure was constructed on the tank floor and then raised using two powerful fans.
According to Inpex General Manager, Vince Kenny, the lifting of the roof to its final height of 32 m took just over 5 hr to complete and required only 0.3 psi of air pressure.
The project will use the same process to raise the roofs of two remaining cryogenic tanks at Bladin Point, including one propane tank and one butane tank.
Over 80 people were involved in the lift, including a team of 30 welders who ascended the tank to fix the roof to the outer walls.
Each of the project’s two LNG storage tanks will have a capacity of 165 000 m3 and will stand 46 m high and span 91 m.
When operational, the Ichthys LNG project will require three LNG carriers and one LPG carrier to export product from Darwin Harbour each week, as well as one or two condensate carriers per month.
