  • Marine Monitoring of Gulf of Mexico Deepwater Floating Systems
    With a combination of wind, wave, and current data; platform surge, way, heave, pitch, roll and yaw; mooring line tensions; ballast tank levels ; and even ballast valve position data; a direct cause and effect relationship can be established. Different types of instruments are used to measure various marine parameters of interest. A brief description of the individual instruments/ sensors is given below. Typically, mechanical propeller type or ultrasonic wind sensors are used.
