<p>Personnel evacuation apparatus (10) for use with an offshore platform (11) comprises a launching ramp (12) that is mounted to the platform by a gimbal (33) and is stowed in a vertical position with a survival vessel (14) secured at the entry end of the ramp. A release mechanism (18) activatable from the deck of the platform (11) enables flotation members (24) secured to the exit end of the ramp, to pivot the ramp about the gimbal to its deployed position. In a preferred embodiment the gimbal (33) further permits the ramp to maintain a usable orientation inspite of inclination of the deck of the platform by 25 DEG due to pitch, roll or yaw. The exit end (20) will pivot under wave action so as to gravity launch the survival vessel (14) downwind and, upon release of the boat securement, carry the vessel safely away from the platform.</p> |
