Ⅳ. Result of R&D

“Development of plastic buoy as 3m diameter module type for eco-friendly and easy-maintenance” carried out.
Making the two prototype model, which was proven via the reliability evaluation test. The result of the R&D are obtained such as Patent 1, PCT 1, international Proceeding 1, domestic proceeding 1, international published 1, master’s degree 3 person and sales record 2.

1. Modular Floats
The modular floats are manufactured pieces 6 divides designed as to ensure the durability and strength of the overall structure. In the research and development of mold technology and forming technology to produce a prototype. It manufactured rotor molding methode.
Plastic raw material PE was ensuring the reliability such as through accelerated weathering test of KATRI (SAE J 1960, 60 days) and photo degradation test in explosion-proof test (KS C IEC 60079-0, 1000 hours).
In addition to verifying the reliability evaluation test such as the weather resistance test and impact resistance test of the material.
The thickness of the modular floats are measured 7 point, were achieved at least 15.5㎜. In addition carried out an impact test in KOMERI secured the product strength reliability. Addition was completed, the development assembling jig and the assembly process for assembly ease.

2. Modular Mast
The modular Mast was designed and manufactured with a hexagonal shape to ensure visibility, the research and development was carried out two models. Wind pressure (60m/s) to perform a structural analysis after the flow analysis was obtained for the theoretical structural strength. Application of the Marine Grade aluminum for lightweight that Mast was modular in three for ease of assembly, Mast has developed a bolt fastening structure. The Mast material was secure reliability through the salt spray test (IEC 60068-2-52, about 30 days) in KOMERI.

3. Steel Structure
The steel structure was designed to assembly with two model of Mast structure. Since the load is concentrated on lifting eye and mooring rings, the structural strength analysis was to ensure the reliability. Surface Treatment of Steel Structure was the "Shot Blast Cleaning (SA2 1/2)" after the hot dip galvanization process (2 kinds, HDZ55, 550g / ㎡, film thickness over 77㎛).
This is to delay the corrosion by sea water and a long period of time, preventing the water pollution.

4. Parts(Top Mark, Light Support, Adjustable Ballast)
Top Mark was lighter in the rotational molding process using PE material. Light Support structure was designed in consideration of the stability and ease of assembly, this prototype was produced by Stainless Steel material.
Adjustable Ballast structure was designed as a half-moon shape, it was designed to be assembled and disassembled in Steel Structure.

5. Battery Case
The battery case compact design considering the ease of opening and closing for the inspectors. It was developed both waterproof structure design and air vent for preventing condensation. A prototype was produced by installing a safety valve at the external Battery Case for safety. To consider for corrosion by seawater applied the Stainless Steel material. in addition painted inside and outside. In addition, in the LED-Convergence Technology Center performs the waterproof test (KS C IEC 60529, IP-X6) secured reliability.

6. Stability design
After stability calculations for the two models of 3M Plastic Buoy (Type-1, Type-2) were selected mooring system specification of the chain, sink etc, on the basis of the result.
The light buoys weight, draft and resilience is to perform a comparative the onshore and offshore test results and test stability calculations were verified Light buoy design technology.

7. Derivation of 3m plastic light buoy standard(draft)
The standardization propulsion for special material buoy of Maritime Affairs and Fisheries. It proposes to derive a standard(draft) of the 3m plastic light buoy by KOMERI

8. Mooring Buoy
3m Plastic Modular Floats using the mooring buoys study was carried out.
This was the mooring buoy structure designed two models. The mooring rings that concentrate the load is ensure theoretical reliability by structural strength analysis

9. Goal Achievement
Quantitative performance targets and achieving value
Performance Target of metering and achieve value
