ABSTRACT:
In the connection of a relatively inflexible pipe to a submerged well head at a depth which may be greater than that to which divers can descend, a pipe placing structure is first locked onto the well head and the pipe is then lowered and automatically connected to the placing structure, a bell housing a sub-assembly including the master valve is next lowered onto the well head and locked thereon by a bearing structure to which the bell is attached. A crew is transferred to the bell to connect the sub-assembly to the well head and to a connector which is automatically connected to the pipe.
