A pipe for drawing up cold water for a marine thermal energy plant is produced from a composite material including glass fiber reinforcements and a thermosetting resin.

Pipe for drawing up cold water for a marine thermal energy plant

A plant for manufacturing a rigid pipe for drawing up deep water within an offshore platform includes a floating platform on which a continuous production device is installed in the vertical axis of the pipe, and including:

Plant for manufacturing a rigid pipe for drawing up deep water within an offshore platform

This plant for manufacturing a rigid pipe for drawing up deep water for a marine thermal energy plant is characterized in that it comprises a floating platform on which there is installed a continuous production device in the vertical axis of the pipe, including a first stage of winding webs of fibers impregnated with resin about a winding roll for the partial crosslinking thereof, said wall being formed by modular elements in the form of plates, which are connected together so as to form a strip that moves in a spiral and repeating in the upper part of the roll so as to form a winding surface for the webs.

Plant for manufacturing a rigid pipe for drawing up deep water

This offshore installation for producing electrical energy from thermal energy of the oceans includes a floating platform supporting a generator for producing electrical energy from the temperature difference of the water at the surface and at a depth and associated with a pipe for drawing up water from a depth, is characterized in that the pipe for drawing up water from a depth include three portions, including a first formed with a rigid pipe, the lower end of which is immersed at a great depth and the upper end of which is immersed in midwater at a reduced depth, a second portion formed with flexible pipes for connecting the upper end of this rigid suction pipe to a third portion forming a suction pipe, formed with rigid pumping pipes structuring a lattice of pipes attached under the platform.
