Abstract
A device (6) for monitoring an anchor (4) for a water vessel is disclosed. The device comprises an accelerometer (32) for measuring acceleration of the device to yield acceleration data, means (38) for processing the acceleration data to yield roll angle data, means (34) for processing the acceleration data to yield velocity data, and means (52, 54) for transmitting the roll angle data and the velocity data from the device to a receiver unit (13) for use with the water vessel. This may allow the setting of the anchor and its reliability to be monitored in an efficient and cost-effective way. A corresponding receiver unit is also disclosed, along with techniques for transmitting the data through a rode.
Claims20
A device arranged to monitor an anchor for anchoring a water vessel, the device comprising:
- an accelerometer arranged to measure acceleration of the device to yield acceleration data;
- a processor arranged to:
- process the acceleration data to yield roll angle data, the roll angle data indicating a roll angle of the anchor;
- and
- process the acceleration data to yield velocity data;
- and
- a transmitter arranged to transmit the roll angle data and the velocity data from the device to a receiver unit for use with the water vessel.
A receiver unit adapted for use with a water vessel connected to an anchor, the receiver unit comprising:
- a receiver arranged to receive anchor roll angle data indicating a roll angle of the anchor and anchor velocity data indicating a velocity of the anchor from an underwater device;
- and
- a processor arranged to determine whether the anchor has set based on the anchor velocity data and the anchor roll angle data.
A method of monitoring an anchor for anchoring a water vessel, the method comprising:
- measuring acceleration of a device attached to the anchor to yield acceleration data;
- processing the acceleration data to yield anchor roll angle data, the anchor roll angle data indicating a roll angle of the anchor;
- processing the acceleration data to yield anchor velocity data;
- transmitting the anchor roll angle data and the anchor velocity data from the device to a receiver unit for use with the water vessel;
- and
- determining whether the anchor has set based on the anchor velocity data and the anchor roll angle data.
