The vessel, supplied instarted working in the Northsea in and was named M. However the operators demanded better performances for drilling in deeper water. In a new rig, based on the Amethyst, was designed with drilling capacities for deep water applications - m. Wikimedia Commons has media related to Semi-submersibles. At face value the size appears similar to typical narco-subs, but the cargo capacity was much smaller at just 1. The diving work would consist of hyper baric welding, installing templates and spool pieces etc.

    Taxonomy There are many ways to categorize, divide up and "slice and dice" these craft. The heavy lift vessels use this capability to submerge the majority of their structure, locate beneath another floating vessel, and then deballast to pick up the other vessel as a cargo.

    This way, the lower hull is well submerged.

    This steel double-hulled Russian designed boat is by far the most sophisticated example yet discovered.

    Offshore drilling in water depth greater than around meters requires that operations be carried out from a floating vessel, since fixed structures are not practical. The capacities of this new design should match with those of a large drilling vessel. There doesn't seem to be any evidence of successful operation of this type but analysis of circumstantial evidence suggests that these are increasingly employed.

    Later types reverted to fiberglass or in some cases sheet-steel construction. It was originally designed for the installation of subsea wellheads and for the first 5 years of the vessel's life it was used in diving support mode, with a split level 18 man saturation diving system installed onboard.
