There is described a method and associated apparatus for connecting a structure to equipment underwater, in particular for connecting a flange to a pipe under water. The pipe is provided under water, and a welding machine is provided in a welding space provided through a section of the pipe, and used to weld the flange to the end of the pipe, for example by internal metal inert gas welding.

Underwater connection operations

A hot tap clamp. The clamp includes a first clamp part, a second clamp part, a fastener for stable fastening of the clamp parts around a section of a pipeline provided with a hot tap coupling, a pipe socket fixedly integrated with one of the clamp parts at an inner end and extending outward from the clamp part to an outer end, a hub on the outer end of the pipe socket, the pipe socket at the inner end going through the clamp part abutting the surface of the pipeline, such that the pipe socket can be sealingly welded to the pipeline by internal welding.
