OSB-W3 (DG) type buoy system for offshore wave
The OSB-W3 (DG) type buoy system for offshore wave is our proposed product, it is suitable for application in sea area of our country.
The diameter of floating buoy is 1.3m with cake shape, the material thickness is 2.5mm 304 stainless steel, and four brackets are fixed with 15KG of stable balancing weight. The anchoring method can be used for two ocean current environments: if it is used in river mouth area with 7 knots of ocean current or more, the pair anchor system can be adopted, the middle floater of which is a 1.4m of hollow steel ball; if it is used with 7 knots of ocean current or less, the direct anchorage with bridle chain can be adopted. This system can supply all parts and structures utilized for above two methods. The offshore environment is often intricate, there are more ships besides ocean current, and the man-made Destruction is also frequently happened..
The seaborne target is largish and can be found easily and the collision of ships can be reduced;
The illumination of riding light is large, it has high position and 4 sea mile of range, the accident at night can be reduced;
The design of anti-collision ring with thick rubber,
The cake shape buoy has better motion response than other general buoys, it is favorable for wave directional measurement;
Various communication antennas, such as satellite, GPRS and radio station, can be easily fixed on;
The data received by Shore Station every time include safety parameters of floating buoy, battery voltage, latitude and longitude, hatch cover, riding light, water leakage and so on;
With stronger charging capability, the solar battery can not be replaced or recharged with continuous usage for four years;
The remote control command is plentiful;
The advanced time correction system by satellite is adopted;
With advanced calculation software of wave height and wave direction, the system can supply wave-height spectrum and directional spectrum.
