Bardex rises to challenge - California, US-based Bardex Corporation designed an unusual lifting system to hoist 350t steel catenary risers offshore on two buoys in the Gulf of Mexico

摘要

Spar buoys (which look like floating upturned logs) pose huge problems where lifting is concerned. The larger of the two has a hull over 200m in length and 46m in diameter. Spars provide buoyancy to support storage and "topsides" facilities, which, in this case, comprised oil production and processing facilities, a drilling rig and accommodation.
