SYSTEM FOR CONTROLLED LOWERING OF A TUBE OR CABLE

摘要

System for controlled lowering of an elongated body such as a tube or cable (14), from a relatively high level, especially the (sea)water level to a relatively low level, especially the (sea)bottom, comprising an elongated tubular guide (18) which is connected to one or more buoyancy bodies, and means for braking the movement of said elongated body through said tubular guide, whereby the braking means (22) comprise a number of braking units incorporated in said tubular guide and distributing over the length thereof, the braking units are under control of a central control unit by means of which the braking force applied by each braking unit can be controlled.
