Abstract
Sphere of application: underwater oil production installations using electrical and hydraulic interconnections between the various assemblies of the underwater station such as well heads, control modules, manifolds and the like. A remote-controlled multiconnector-pod assembly 1a, 1b is located on an underwater base on which is anchored a hollow tube 10 having an upper edge 10a. A disconnectable tool is suspended at the support plate 20 and is provided by a connection jack 30 with a mechanical connector 40 designed to grip on to a mandrel 5 which is integral with the pod. The tool is anchored by jacks 23 and 24 and holes 10b, while the pod is locked into the tube 10 by bolts 6 which extend into the holes 10c of the tube. With this system it is possible to install the pod by remote control and then to raise the tool so as to prevent any danger of it being damaged by sea corrosion.
