Method intended for automatic control of an underwater pipe for connecting the lower end of the pipe to a wellhead, wherein the following stages are carried out:

Automatic control methods for positioning the lower end of a filiform structure, notably an oil pipe, at sea

Pipe for great water depths allowing transfer of a fluid between a floating support and a point situated below and at a distance from the water surface, characterized in that it comprises:

Hybrid riser or pipe for fluid transfer

A drilling and/or production riser includes on at least part of the length thereof, a stiffener suited to withstand strains induced by the stresses transmitted by the marine environment, those induced by said supporting and guide device, and the strains due to the weight of the loads supported by said stiffener. System intended for production of petroleum effluents from a production site, such as one or more production wells, to a floater having at least one assembly allowing transfer of the effluents from at least one of the production wells to the floater. The assembly includes a production riser equipped on at least part of the length thereof with a float and with at least one stiffener situated above the float and suited to withstand strains induced by the stresses transmitted by the marine environment, those induced by said supporting and guide device and the strains due to the weight of the loads supported by said stiffener.
