OSTI ID:6160888
This invention concerns a seabed device to support tubing connected to a wellhead. The device comprises a flange at the bottom end of the tubing, fitting into a rigid frame attached to and detachable from a framework located on the seabed, the said flange being connected to the wellhead by the same number of flexible pipes as there are passages in the tubing, with a connection-disconnection device to attach these flexible pipes to the wellhead. This device relieves the wellhead of stresses transmitted by the tubing.
