Apparatus for detecting position of an umbilical cable or wire rope attached to a load

摘要

An apparatus is provided for detecting position of an umbilical cable 104 or wire rope attached to a load, in which the umbilical cable or wire rope is routed around a sheave wheel 105 and through a snubber assembly 107 suspended from a deployment system 101. The apparatus comprises at least one sensor 701 mounted on the snubber assembly configured to output a signal indicative of the position of the umbilical cable or wire rope 104 relative to the snubber assembly 107. The apparatus may also comprise a sensor housing (802 figure 8) for surrounding the umbilical cable or wire rope 104. The at least one sensor may comprise one or more of a mechanical, ultrasonic, infrared, magnetometer or a hall effect sensor.
