Abstract:

We design a big assembled buoy of 6 m diameter in view of the weak viability of a big overall oceanographic data buoy and the inconvenience of its manufacture and transport. We also employ Ship Static calculation method to determine such basic parameters of the buoy as molded depth of 2.2 m and height of gravitational center of 0.9 m. We then check the stability criteria of the assembled buoy based on the ship stability specification and obtain an assembled buoy satisfying the requirement of usage. The design provides a rational basis for the controllability of buoy manufacture quality.

Key words: buoy, depth of hull, height of gravitational center, stability criteria
