Intelligent fiber rope termination
A cable termination including an integral instrument package providing intelligence. The instrument package may assume many forms and may serve many purposes. In a preferred embodiment, the termination includes a position-determining system and an on-board processor. The processor determines a current location in space for the termination based on the information it is receiving. This positional information may then be transmitted to an external receiver. In the scenario where the termination is attached to a payload, the positional information may be used by an external positioning device (such as a crane) to control the motion of the termination and thereby place the payload in a desired position. The termination also preferably includes load-monitoring and recording features. The termination may also carry one or more ROV's/AUV's.
