Wire-spiralling machine

It is of the type comprising a corrugated and sealed internal metal tube (1), a pressure vault (2) wound at a short pitch and having an internal surface which faces the corrugations of the corrugated internal tube, an intermediate sheath, at least two groups of inner and outer armoring layers (3, 5), the armoring layers being wound at a lay angle of less than 55.degree., and an outer-sheath (6), and it is characterized in that the intermediate sheath (4) is sealed and is arranged between the two groups of armoring layers (3, 5), the said inner group of armoring layers (3) bearing directly on the pressure vault (2).

Flexible pipe for great depths

Stiffener comprising an elastic member made of elastomer which surrounds a elongate body to be stiffened, the elastic member being integrally attached to one end of a housing support. It comprises, inside the elastic material (4), a reinforcement (8) extending over a portion of the length of the elastic member (4) from the end, the reinforcement being integrally attached by fastening (7) to the housing support (2, 6).

Device for laying tubular conduits comprising a submerged mobile pincer

A device for mounting a flexible line including a curvature limiter. The device for mounting a flexible line on a structure, including a hollow rigid member forming part of the structure or fixed to the structure, and which the flexible line passes through after having been pulled with the aid of a pull cable fixed to one end of the flexible line, in particular on the end fitting mounted on the latter for connecting it to the structure, and a curvature limiter engaged on the flexible line and secured to fixing means able to interact with fixing means secured to the hollow rigid member for fastening the curvature limiter to the structure. The device further includes means for immobilizing the curvature limiter on the flexible line at a distance from the end of the latter during a first phase of pulling the flexible line at the end of which the curvature limiter is brought to the level of the mouth zone of the hollow rigid member for the purpose of fastening it, the hollow rigid member comprising, at least during the first pulling phase, a flared mouthpiece.

Device for depositing and recovering a heavy load on the ocean floor

A lower portion of a subsea oil delivery hose is held taut between bouyant devices installed on the hose and a stationary point on the subsea floor. A portion of the lower part of the hose, connected to the stationary point, has a curved portion that is concave in the direction of a wellhead to which the hose is connected.

Apparatus for transferring fluid between subsea floor and the surface

Connector for quick release under load, particularly for pipes for transporting fluids such as hydrocarbons, characterized by the fact that it comprises, between two opposite structural elements (1, 2) or between two parts of an element connecting the two structural elements, at least a connecting device comprises an internally shaped annular ring (7) consisting of at least two segments of complementary shape, a rod (4) equipped with an outside shaping corresponding to the inside of the ring, engaged internally in said ring and extending over at least a part of its height and an annular sleeve (6) engaged on said nut and able to be moved axially in relation to it under the effect of an actuating element, such as a cylinder (12) acting directly or indirectly on said sleeve.
