Kvaerner raises the roof in India - again

Press release 20/04/2000 00:00 CET

For the second time in a month Kvaerner has lifted the roof of one of the largest LNG tanks in the world into place using powerful electric fans. This lift took six-and-a-half hours and follows a similar lift which took place three weeks ago.

Kvaerner is currently constructing three LNG tanks – all bigger than London’s Royal Albert Hall – in the remote region of Dabhol south of Mumbai as part of an LNG facility. Working to a tight schedule the company has been aiming to complete the external construction of these tanks before the monsoons set in. With the roofs in position on Tank T-300 and Tank T-400 work on the internals can now proceed without disruption from the rains expected around mid-May. The final roof air lift is forecast for August.

The domed roofs are made from 600 steel sections inside the tanks while the tanks’ walls are being simultaneously constructed. Weighing 770-tonnes and measuring 80 metres across, they are air lifted 40 metres into position using compressed air.

Kvaerner is the main contractor with Whessoe providing design support on this US$278 million turnkey project for Enron affiliates, which are managing the construction of LNG facilities for the Dabhol Power Company. The contract is to supply, construct and equip facilities to offload LNG from ships in minus 160 degrees centigrade liquid form, pipe it to a storage centre where it is vaporised into gas and then pumped into a power station.
