Definitions
- TITLE METHOD AND SYSTEM FOR HIGH SPEED
- a typical example is the delivery of remotely operated vehicles in cages or other devices so that
- the surrounding water provides resistance to the descent of the load beyond a certain speed.
- the object of this invention is to allow feedback to personnel on the vessel
- a tension sensor is placed adjacent the load and sends a
- the sensor will indicate a reduction in tension, giving a signal to the personnel at the surface that the payout rate is too
- the sensor measures directly the tension in the cable to prevent
- the present invention is directed toward a monitoring system for the deployment of loads
- the invention comprises a cable and an apparatus capable of paying out or taking out the cable from the surface.
- the invention further comprises a sensor
- Figure 1 is a side view of the system of the present invention showing the preferred location of the tension sensor.
- FIG. 2 is a block diagram of the control system of the present invention.
- a vessel 10 is shown floating in a body of water 12. It has an
- apparatus 14 which is able to take up and payout cable 16 over a boom 18.
- apparatus 14 which is able to take up and payout cable 16 over a boom 18.
- apparatus 14 is a winch mounted on the vessel. At the end region of cable 16
- tension sensor 20 which is located adjacent load 22, as shown in Figure 1.
- the tension sensor 20 is capable of measuring tension in the cable 16 at the
- the load 22 is connected adjacent one end of the cable 16.
- the power/signal line 24 can be included in the cable 16
- the invention comprises a processor 30 to receive a
- measurement signal 32 from the sensor 20 and to use the signal to regulate take up or payment
- the processor is capable of sending
- the processor 30 receives a signal from the sensor 20, via the signal transmission
- the winch 14 pays out cable 16 at the selected rate.
- the most desirable location for the tension sensor 20 is as close as possible to the load
- the location of the tension sensor 20 is less critical. If the cable 16 is being taken up at too high a rate, the sensed tension will rise at
