Apparatus and methods for the launch and recovery of craft from and to a host ship

摘要

A system and method for determining and displaying the suitability of water conditions in a zone for the launch or recovery of a smaller craft (10) from or to a host ship (12) is disclosed. The system and method detect one or more external environment parameters such as the height, direction and period of the swell, and one or more parameters relating to the ship operating conditions such as the heading, speed, pitch and roll angles, and processes these to determine the suitability of the conditions for launch or recovery.

主权项

1. An apparatus for providing an indication of a suitability of water conditions in a launch/recovery zone for launch or recovery of a smaller craft from or to a host ship, the apparatus comprising:
one or more sensors for detecting one or more parameters relating to an external environment of the host ship including:
swell height;swell direction; andswell period; one or more sensors for detecting one or more parameters relating to the host ship including:
current ship heading;current ship speed;ship pitch angle;ship roll angle; and a processor for receiving and processing the one or more detected parameters relating to the external environment of the host ship and the one or more detected parameters relating to the host ship, and for providing a signal indicative of the suitability of the water conditions in said launch/recovery zone.
