Abstract
For connecting an offshore structure to a submarine pipeline, a vertically-extending pipeline is built as an integral part of the structure and is provided with a receiver fitting at its lower end which is adapted to mate with a connector fitting provided on the end of the submarine pipeline. By means of special tools, all manipulatable from the surface, mating, locking, and sealing of the two fittings are accomplished, followed by pressure testing of the coupling between such fittings.
