ABSTRACT:
An apparatus for attaching a flexible line, such as a multiconductor electric cable for power and control circuits, a single flexible hose, or conventional flexible cables to a subsea station by remotely controlled means and without the assistance of divers or diver capsules or submarines. The apparatus includes a cable connecting frame structure upon which is pivotally mounted a socket-like container means which receives a receptacle means connected at one end of a flexible power cable or line. The frame structure is adapted to be releasably attached to the subsea station. A plug assembly is receivable by the socket-like container for electrical engagement with the receptacle means, and lock means holds the socket-line container in a selected position with respect to the subsea station. A method of connecting a flexible line to a subsea station in which a cable connecting frame structure carrying a socket-like container receiving a receptacle means provided at one end the power line is lowered to the subsea station by a running tool which has latched engagement with the frame structure and holds latch members on the frame structure in release position for reception of guide posts on the subsea station. Release of the running tool from its latched engagement with the frame structure provides latching of the frame structure to the guide posts so that the running tool may be retrieved. A method in which the running tool may also be used for retrieving the frame structure for service of the electrical receptacle means carried by the frame structure.
