Howard Allson Delivers Edvard Grieg Helideck

Description

The Edvard Grieg field is located in the Utsira High area in central North Sea, where Lundin Norway’s main focus area is located. Edvard Grieg is a 7 floor living quarters module for Lundin’s Topside with an area of 2600 m² and a capacity of 100 single cabins, administration centre, central control room and all other facilities required for operation of an offshore hotel.

The living quarters and helideck are both constructed in aluminium, which features low weight, minimum maintenance in operation and environmental friendliness. The total weight of the living quarter and helideck is 1250 tons.

Our Norwegian partners, Apply Leirvik A/S, built the aluminium living quarters while Howard Allson Ltd was awarded the project to design and build a 26.1m XD standard helideck incorporating an approximately 5m high aluminium support truss with a full perimeter walkway. The helideck is designed to cater for Sikorsky S92A operations and is in compliance with Norsok C-004. This is the first Howard Allson Ltd project where we employed a fitted bolt design with locknuts for all primary structural bolts in the helideck structure. This design effectively reduces structural movements, possible joint slippages and loosening of fasteners.

This helideck was lifted into place in May 2014.
