Improvement of directional wave information and quality control before real-time telemetry of heave-pitch-roll metocean buoys

Abstract

The transmission of metocean data collected in real-time is essential for marine operations. Due to the high cost associated with satellite communication, the complete characterization of sea state is impaired. The moderns single boards computers, enables the development of dedicated modules for processing and quality control of the collected series, allowing to perform more complex tasks and transmitting additional information relevant to the characterization of sea states. The main goals of this work is to increase the reliability of real-time data, transmitted by heave-pitch-roll buoys and verify the efficiency of a single board computer to execute the traditional wave processing by Longuet-Higgins and DAAT, including automatic quality control. This new wave data processing system allows a deeper evaluation of the information that can characterize a sea state of a time series that was stored inside the buoy and was not transmitted in real-time.
