<p>A bending-restricting anchoring arrangement for anchoring a flexible pipe (1a,1b,1c) for the transport of a fluid between a seabe d (8) and a sea surface consists of first (2) and second (3) holding sleeves, which, spaced from each other, are adapted to hold a section of the flexible pipe near the seabed. The first holding sleeve (2) is secured via a rigid connecting member (5) to a fixed point on the seabed, while the second holding sleeve (3) is movable in a well-defined manner relative to the first connecting sleeve. In an embodiment, the second holding sleeve (3) is secured to a support (9) movable on the seabed. The first and second holding sleeves are connected to each other by means of a mechanical coupling (11) which may be formed by a plurality of rigid members (5, 16, 17, 18), which maintain a fixed distance between the holding sleeves (2, 3) and thereby the geometry of the pipe section disposed between the holding sleeves, in several different ways, via connections between the first and second holding sleeves and/or via connections between their respective rigid connecting mem bers. The invention ensures that the forces acting on the flexible pipe because of sea currents, tensile stresses, etc. which occur because of buoyancy when the reinforced pipe is immersed into water, or because of tensile forces that occur because of the use of floating members, are absorbed in the most optimum manner and without any risk of overbending of the section of the pipe (1b) between the connection sleeves (2, 3).</p> |
