Diaphragm

Diaphragm Closures are most important and critical installation aid for launching of Offshore Jacket. The critical function of these Diaphragms is to withstand very high hydrostatic pressure while launching the offshore jackets. Diaphragm closures seal the platform legs and skirt sleeves to provide buoyancy during the installation of substructures. These closures are attached to the legs and skirt sleeves by means of fastening ring/flanges that also hold the rubber diaphragms. They are made from highly reinforced rubber and are designed to withstand the hydro-static pressure during jacket flooding operations.
