Abstract
A releasable connection comprising a first member removably inserted in a second member with space between adjacent opposing surfaces of the members; a solid mass of a material, in the space between the members, which firmly joins the members together; said solid material having substantial compressive, tensile and shear strength, and being convertible by heat at a sufficiently high temperature to a physical state in which it has much lower compressive, tensile and shear strength; and, apparatus associated with at least one of the members for supplying heat to the material. The material, for example, may be ice, a low melting metal or a polymeric material. The releasable connection can be used onshore or offshore. It can be used to releasably secure an offshore structure to a seafloor, such as in the artic, using ice as the material.
