Abstract
A leg mating unit for installation of offshore structures. A housing has a ram movably mounted in the housing. Elastomeric material is received in the housing immediately below the ram. An open space below the elastomeric material is filled with a disposable, granular material such as sand. A drain valve for selectively releasing the disposable material is provided on the housing. A load absorbing ring is engaged with the ram. A stop ring is rigidly mounted on the leg of the topside structure and engages the load absorbing ring during installation of the topside structure onto its lower supporting structure. The housing is removably mounted on the lower support structure such that the leg mating unit is removable and reusable.
