Abstract
Apparatus for monitoring the laying of a deep sea cable or flexible pipeline (1) from a vessel (22). The apparatus comprises a sleeve threaded on the cable or flexible pipeline and having sliding means (4) tangential to said cable or pipeline and measuring means (3A) for measuring variables indicative of the position of the sleeve and for transmitting their values, positive buoyancy means (8) mechanically connected to the sleeve, an auxiliary small chain (19) suspended from the sleeve and extending down to the sea bed, the mass per unit length of the chain, and the masses and volumes of the sleeve and of the positive buoyancy means being such that the sleeve is maintained around that part of the cable which is situated at a substantially constant height above the sea bed (21), which height is relatively small compared with the depth of the sea bed.
