Spherical articulation connecting pipeline to submerged well head - comprises flexible joint formed by stack of alternating layers of rigid and elastic material

摘要

A system for remote control and maintenance of a submerged satellite well head comprises a platform and a pipeline extending to the well head. The pipeline is connected to the platform by a connector and to the well head by a spherical articulation equipped with a flexible joint. The articulation can slide vertically relative to the well head and is rigidly connected to the well structure. The flexible joint is formed by a stack of alternating layers of a rigid material and an elastic material which adhere to one another. Remote control, maintenance or fluid injection of a submerged well head. The provision of the flexible joint permits relatively large angular displacements of the platform. Measuring and maintenance operations can be performed rapidly and at reduced cost since only an inexpensive small boat. Remote control of several well heads can be effected from a central station without having an energy distribution network on the sea bed.
