44 Apparatus for handling submersibles at sea US946369 1978-09-27 US4312287A 1982-01-26 Chengi Kuo
A ship or other vessel having a moonpool therein and an enclosed space above the moonpool is provided with a pontoon which floats on the surface of the sea within the moonpool. The effects of the enclosed space is that said sea surface is calm even when the ambient sea is subject to an adverse swell, and the effect of the pontoon is that it will remain substantially stationary and be independant of the vessels heaving motion, i.e. the pontoon is de-coupled from the vessel. Lifting gear mounted on the pontoon is used to lower and raise submersibles, sub-sea equipment, tethered bells or divers (tethered or free swimming). The pontoon may be used as a stable work area and for loading and unloading cargo; in the latter case, a housing forming the enclosed space above the moonpool has a double opening through which the cargo can pass, but only on opening at a time is opened so as to preserve the enclosed space above the moonpool.

50 Method of connecting of an undersea central station to a group of undersea wells and outflow pipes US565971 1975-04-07 US4023619A 1977-05-17 Roger Andre Marie Marquaire; Michel Georges August Curtis; Robert Edouard Schappel
A method and apparatus for connection of a central undersea station to a group of wells and outflow pipes is disclosed. The undersea station locks onto a platform which has a series of guides and locking devices to receive and lock the station relative to itself as well as to other locations for the installation of wellheads which are to be ultimately serviced by the station. The method essentially comprises that prior to the connection of the wells and the pipes a guide member is installed on the platform between the location of the station and each of the locations of the wells or pipes and then the central station is lowered and is provided a lateral connection device such that when the platform is locked into position, the lateral connection device is opposite the guide on the platform. Placing structures are lowered onto other locations and a connecting structure is generally lowered by means of a diving bell which rests in a watertight manner on a bearing surface of a connecting structure which orientates the bell so that the structure presents a lateral connection cooperating between the guide means of the platform and a connector which insures the water tightness of the well or pipe. Manual connections inside the bell of a subassembly to the lining of the well or pipe are achieved and at least one pipe system between the subassembly and the lateral connection on the structure to insure continuity of the lining or of the pipe with the lateral connection means is disclosed. When this lateral connection device has been joined with the connection structure of the station, the bell is then brought to the surface.

52 Method and apparatus for joining a subsea pipeline to an offshore platform riser US557121 1975-03-10 US3967462A 1976-07-06 Jan DeJong
Apparatus includes an offshore platform riser subtended by a joint chamber having port means for receiving a subsea pipeline and access means for a submersible capsule. The riser and chamber are attached to the platform in such manner as to provide for thermal expansion and to permit detachment when an abnormal loading is encountered. Platform winch means attached to cable means passing through the riser and chamber are used to pull an end of the pipeline into the chamber. Personnel utilizing the capsule then enter the chamber for completing the joining of the pipeline and riser. The joining and subsequent inspection operations are conducted at substantially atmospheric conditions in the chamber.
