Abstract

A capsize alerting apparatus (40) for a maritime vessel (10) is provided. The capsize alerting apparatus comprises an antenna (15) which is fixed on the maritime vessel in an orientation which permits communication with a receiver when the vessel is in a capsized state. The antenna is further operable when the vessel is in the capsized state to transmit a capsize alert message indicating that the vessel has capsized. Accordingly, by fixing an antenna to the vessel in an orientation which permits communication with a receiver when the vessel is in a capsized state, the vessel is able to communicate a capsize alert signal to a receiver (20) even though the vessel is in a capsized state in which a conventional communications system will not function.

Claims

1-20. -20. (canceled)

21. A capsize alerting apparatus for a maritime vessel, the capsize alerting apparatus comprising:

an antenna being fixed on the maritime vessel in a position and an orientation which permits the antenna to communicate with a receiver when the vessel is in a capsized state, the antenna being further operable when the vessel is in the capsized state to transmit, from its fixed position on the maritime vessel, a capsize alert message indicating that the vessel has capsized.

22. A capsize alerting apparatus according to claim 21, wherein the antenna is positioned adjacent to a hull of the vessel.

23. A capsize alerting apparatus according to claim 21, comprising a positioning device operable to determine the geographical position of the vessel, and wherein the capsize alert message includes information indicative of the determined geographical position.

24. A capsize alerting apparatus according to claim 21 comprising a capsize detector for detecting that the vessel has capsized and controlling the antenna to transmit the capsize alert message in response to the detection.

25. A capsize alerting apparatus according to claim 21, wherein the capsize alert message comprises an indication of the identity of the vessel.

26. A capsize alerting apparatus according to claim 21, wherein the antenna is operable to transmit further capsize alert messages while the vessel remains in the capsized state.

27. A capsize alerting apparatus according to claim 21, wherein the antenna is operable to receive an acknowledgement message communicated to the vessel in response to the capsize alert message, and wherein the capsize alerting apparatus is operable in response to the acknowledgement message being received by the antenna to provide an indication that the capsize alert message has been received.

28. A capsize alerting apparatus according to claim 21, wherein the antenna is fixed to the outside of the vessel.

29. A capsize alerting apparatus according to claim 21, wherein the antenna is fixed within the vessel.

30. A capsize alerting apparatus according to claim 21, wherein the antenna is integrally formed with a hull of the vessel.

31. A maritime vessel comprising a capsize alerting apparatus according to claim 21.

32. A method of alerting of a capsize of a maritime vessel, comprising the steps of:

fixing an antenna on the maritime vessel in a position and an orientation which permits the antenna to communicate with a receiver when the vessel is in a capsized state; and

transmitting, from the antenna in its fixed position on the maritime vessel, a capsize alert message when the vessel is in the capsized state to indicate that the vessel has capsized.

33. A method of alerting of a capsize of a maritime vessel according to claim 32, comprising the steps of

determining the geographical position of the vessel;

and

providing information indicative of the determined geographical position within the capsize alert message.

34. A method of alerting of a capsize of a maritime vessel according to claim 32, comprising the steps of

detecting that the vessel has capsized;

and

controlling the antenna to transmit the capsize alert message in response to the detection.

35. A method of alerting of a capsize of a maritime vessel according to claim 32, comprising the step of

providing an indication of the identity of the vessel within the capsize alert message.

36. A method of alerting of a capsize of a maritime vessel according to claim 32, comprising the step of

transmitting further capsize alert messages while the vessel remains in the capsized state.

37. A method of alerting of a capsize of a maritime vessel according to claim 32, comprising the steps of

receiving an acknowledgement message communicated to the vessel in response to the capsize alert message

providing, in response to the acknowledgement message being received by the antenna, an indication that the capsize alert message has been received.

38. A method of alerting of a capsize of a maritime vessel according to claim 32, wherein the antenna is fixed to the outside of the vessel.

39. A method of alerting of a capsize of a maritime vessel according claim 32, wherein the antenna is fixed within the vessel.

40. A method of alerting of a capsize of a maritime vessel according to claim 32, wherein the antenna is integrally formed with a hull of the vessel.

41. A capsize alerting apparatus for a maritime vessel, comprising:

antenna means, fixed on the maritime vessel in a position and an orientation which permits the antenna means to communicate with a receiver when the vessel is in a capsized state, for transmitting from its fixed position on the maritime vessel, when the vessel is in the capsized state, a capsize alert message indicating that the vessel has capsized.
