Research & Development
Contribution to the global environment
Friction resistance is mainly attributed to the roughness of coating surfaces. Normally roughness control of ship bottom paint surface is conducted by measuring the roughness height (peak height). However, double cylinder tests conducted by Tokyo University of Science, flow simulations by Tokyo University of Agriculture and Technology using a supercomputer, and tank tests by National Maritime Research Institute (NMRI) using ultra high precision parallel plates indicate significant contribution of the roughness wavelength (distance between peaks) to the friction resistance.
Reducing fuel consumption by ships contributes to the preservation of finite resources on the earth and reduction in CO2 emissions. CMP further progress fuel-saving effects by using the FIR Theory as the indicator.arine factors involved.
Reducing friction resistance of the hull bottom leads to fuel saving.
The reduction technology of friction resistance by anti-fouling paint is gaining more expectations under the circumstances of environmental regulations for ships, e.g. EEDI (IMO: Energy Efficiency Design Index), since it is claimed that the friction resistance is about 60-80% in total hull resistance which greatly affects the fuel consumption of vessels.
Correlation between roughness, wavelength and fuel-saving effect
Our R&D activities always aim to reliable and environment-conscious products. Core products are manufactured and supplied worldwide. We develop products taking in global ideas at our technical research centers in China, Singapore.
Always looking ahead to the future, our R&D covers from basic research on materials to brand new coating technologies. Feedback from customers received through Sales Department are positively reflected in our product developments.
Doing thorough experiments and making full use of advanced inspection equipment, the company conducts research into basic/applied coating technology, promoting mid/long term research activities in areas ranging from material science to the development of high performance, and quality products. In order to reflect customers’ product-related requirements, which are necessary in effective R&D, information is actively exchanged with the Sales department. The results of R&D are applied widely in new product innovation, environment protection, and improvements in existing products.
Unveiled "Premium range of new CMP AF"
Chugoku Marine Paints, Ltd. (CMP) unveil new products, utilising new biocide technologies.
Chugoku Marine Paints, Ltd. (CMP) unveil new products, utilising new biocide technologies. The initial phase of the R&D program focusing upon the new biocide technologies was finalized well over 10 years ago, hence since half way through the last decade over 100 trial applications with the new biocide technologies were continuously carried out on commercial ships and are now resulting in 10 years of ship outturn experience and data providing the confidence to introduce the new products emanating from such technologie.
FIR Theory
We have established FIR theory which can estimate the Friction Resistance by measuring and evaluating roughness(Rz) and wavelength(RSm) of the paint surface, and have been carrying out the evaluation of fuel saving effect with more accuracy.
