摘要:
A guide system (1) for guiding a pipeline (2) from a laying vessel (5) onto the bed (3) of a body of water (4) has a float unit (8); a trolley (12), which is housed inside the frame (11), is selectively connectable to a pipeline (2) spanning a given path (P) between the laying vessel (5) and the bed (3) of the body of water (4), and is designed to roll along the pipeline (2), parallel to the given path (P); and at least one motor (30) connected to the trolley (12) to selectively adjust the distance between the float unit (8) and the laying vessel (5).

The present Invention concerns a clamp (20) for mounting upon an elongate member such as a riser (24) to be deployed underwater. The clamp may for example be intended to prevent movement of a buoyancy module along a riser. The clamp comprises a plurality of clamp bodies (22) to be placed at circumferential intervals about the elongate member. A strap (42) is provided which is to be placed around the clamp bodies and tensioned to urge the clamp bodies toward the elongate member, enabling the clamp to resist movement along it. The clamp bodies comprise respective spring elements (28) which are arranged, when the clamp is assembled and mounted, between the clamp bodies and the elongate member. The clamp bodies and the spring elements are shaped to permit them to be used in clamps having a range of different diameters and having a differing number of clamp bodies.

The invention relates to a method for installing a self-supporting tower. According to the method, an anchoring mechanism (32) is provided and installed on said bed, and a float (18) and a tubular pipe (68) are provided. Next, said float (18) and said tubular pipe (68) are submerged, then said float (18) and the tubular pipe (68) are driven towards said bed (12) in order to hitch one of the ends (72) of said tubular pipe to said anchoring mechanism (32), while said float (18) is securely fastened to the other (70) of the ends in order to keep said pipe (68) vertical above said anchoring mechanism (32). According to the invention, said tubular pipe (68) and said float (18) are supplied separately, and the float (18) is kept submerged at a distance away from said anchoring mechanism (32); and said tubular pipe (68) is suspended from said float (18) via said other (70) of said ends.

An object of the present invention is to provide a marine hose of which a limit mechanism does not work unnecessarily at the time of being wound up to a reel. In the marine hose of the present invention, protruded parts (14a) are provided at each axial direction end of the axial direction ends of the hose bodies (10), said each axial direction end is located at both sides in the axial direction of the connection portion (20) which is provided with limit mechanism (30). By this, when the marine hose is wound up to the reel, the protruded parts (14a) of the hose bodies (10) contact the outer surface (RE) of the reel, the outer surface of the limit mechanism (30) does not contact the outer surface (RE) of the reel. Thus, large amount of the bending force is not added to the limit mechanism (30).

The invention relates to an assembly of support buoys (12) for a flexible submarine pipeline (10) which is designed for the transport of hydrocarbons. The inventive assembly of buoys includes: a plurality of buoys (12) which can be installed gradually on at least one portion of the flexible submarine pipeline (10) and fixing means which can be used to block the translational movement of the buoys (12) on said portion of the pipeline (10). According to the invention, the fixing means include: a coupling line (14) which connects each of the buoys (12) successively to one another, the translational movement of each of said buoys being gradually blocked on the coupling line (14); and connecting means (16, 18) which maintain the coupling line (14) taut along said portion of the pipeline (10).
摘要:
It consists of a parallelepiped body (1) comprising a lower zone (2) provided with supports or legs (3) located in the corners, on which an upper parallelepiped zone (4) is connected, said upper zone having a trapezoidal section and with a lower central rectangular projection (6) and an upper rectangular recess (5). Both zones (2, 4) have the same length, but are offset linearly in order to define complementary tongue-and-groove coupling means for in-line assembly. The rectangular recess (5) define the bed for laying the submarine outfall or pipeline, the bed being covered with slabs (9) which are fixed to the upper zone (4) with rods. The elements or bodies (1) are also fixed to one another with vertical rods (15).
