Stabilized offshore platform
Abstract
Abstract THE INVENTION RELATES TO A DYNAMICALLY STABILIZED, OFFSHORE PLATFORM SUPPORTED BY AN ELONGATED RIGID STRUCTURE HAVING THE LOWER END FASTENED INTO THE FLOOR OF A BODY OF WATER. THE STRUCTURE INCLUDES A SIGNAL GENERATING MONITOR SYSTEM ADAPTED FOR CONTINUOUSLY MONITORING THE DEGREE AND FREQUENCY OF THE STRUCTURE''S LATERAL DISPLACEMENT. THE DISPLACEMENT IS AUTOMATICALLY COUNTERACTED BY AN UNDER WATER REACTIVE FORCE PERIODICALLY APPLIED TO THE STRUCTURE IN A DIRECTION OPPOSITE TO THE DISPLACING FORCE, AND AT A MAGNITUDE AND FREQUENCY IN ACCORDANCE WITH THE GENERATED SIGNAL WHEREBY TO AVOID THE CREATION OF A HARMFUL RESONANT VIBRATION IN THE STRUCTURE DUE TO CONSTANT WAVE ACTION.
