Abstract
A floatable oil/gas production platform assembly has a deck, disposed beneath the deck a zone including a plurality of adjacent stations for support of oil/gas flowlines/risers originating from beneath the platform, and a crane disposed in a space above the station zone but below the deck and moveable over at least some of the stations. Such an assembly enables two new alternative equipment arrangements to be provided in floating platforms for tensioning and supporting underwater well maintenance lines or 'workover risers' which require considerable tensioning forces and stroke capacity for safe support.
