Case Study: Flare Boom

Stands and flare boom.

Designed to allow removal, offshore transit and onshore storage of two flare boom structures these fabrications were designed and analysed by the Ardmore Craig team to support an offshore semi-submersible that was working in the North Sea.

Working from as built drawings from a foreign yard and survey photographs from the rig, the team developed a design to allow the boom structure to be removed without having to break it down into the original parts when it was first installed on the rig.

The fabrication and associated seafastening arrangement was designed to allow installation on a range of vessels of opportunity and was modular in construction for road transportation.

The 20 tonne units were designed for offloading with the booms lashed in place and for long term quayside storage.
