ABSTRACT:
An inflatable underwater structure for providing an artificial environment around a work area, for example, at the sub-sea base of an off-shore oil platform, permitting such work as welding and the like; the structure is made up of one integral sheet of material for a custom job or a series of selected sheets fastened together about the structural support members; the material includes zippered sections so that the material can be placed about and around the structural members; in order to insure a substantially air-tight system, neck sealing means are included about the structural members at their intersection with the sheet material as well as air-tight means within the zippered sections; although the system could be used on land, it is particularly applicable to sub-sea situations.
