Abstract: Method for preparing an elongated object (22) having a relatively high bending stiffness, such as an elongated tube or cable, before storing and/or transporting object, wherein a) the elongated object is provided with sufficient buoyancy capacity to enable the object to float on a liquid (14) with a predetermined specific gravity and that b) the elongated object (22), while floating on the liquid and carried thereby, is spirally wound into a flat monolayer spiral (36), the inner radius of which is preferably in the order of the diameter of the elongated body divided by the yield point (ratio) or larger of the most fracture critical material in the elongated object.
Abstract: A system for controlled lowering of an elongated body such as a tube or cable, from a relatively high level, especially the water level to a relatively low level, especially the (sea) bottom. The system includes an elongated tubular guide that is connected to one or more buoyancy bodies. The system also includes a braking device for braking the movement of the elongated body through the tubular guide. The braking device includes a number of braking units incorporated in the tubular guide and distributed over the length thereof. The braking units are under control of a central control unit which controls the braking force applied by each braking unit.
