Design of Marine Monitoring Floating Standard Based on RAO Analysis

Abstract

With the development of science and the progress of society, human beings are gradually developing their use of the ocean, so pollution, especially in nearshore zone, becomes more serious. Thus, effective monitoring of the ocean is particularly important. Marine buoys which are the main means of marine monitoring are widely used in marine hydrological and meteorological data collection due to their high reliability, good stability, and high efficiency. Coastal water is mainly monitored by using small-sized buoys of 3 meters. The quality of current prevalence traditional marine buoys product is not good because they are easily influenced by the wave of oscillation which has certain extent effects on its normal work. With the help of the research project of the Shanghai Science and Technology Commission of Science and Technology Innovation Action Plan "the mechanism of the Arctic Ocean observation buoy failure and the service safety study (11JC1404700)", This research is based on the 3-meter buoys in China's offshore, and use AQWA of the ANSYS software to analyze three hydrodynamic characteristics of buoys, The hemisphere-type floating body which is more suitable for the coastal marine environment is selected by comparing the value of the roll response and the heave response, and actual sea trials were conducted.
