In-depth | CHINA SHIP NEWS Outlook on China’s green future


Weng Zhenping, director at China Ship Scientific Research Center talks about the development of shipping technology, writes Wang Sun


T


he director from China Ship Scientific Research Center, Weng Zhenping, illustrates


how cutting-edge green shipbuilding technology will be integrated with conventional shipping equipment, and how it should dynamically combine functional and performative demands with that of energy saving and environmental protection. In the whole life cycle of a vessel,


including ship-design, manufacturing, operating and scrapping, the industry must conserve energy and resources, reduce or eliminate environmental pollution, guarantee the safety and health of manufacturing staff and users with new technology. This concept is universally accepted in the industry, exemplified by the various newly promoted international conventions, standards, and norms, all of which have higher demands for design, manufacturing, energy consumption and performance. Many western countries already have strict requirements on the exhaust standards of vessels moored in a harbour. Te above environment pushes different


ship research institutes and shipbuilding enterprises dedicated to R&D, to produce new technology, new vessels and new energy sources that are in accordance with the ‘green ship’ concept. Weng Zhenping says that within


this decade the shipping industry in China has gained great impetus for development and formed the competence for R&D, design, production and support systems. “Our production size and


comprehensive competence have continuous ly expanded, wi th conspicuous advantages in the research and development sector. We are now the most powerful shipbuilding country in the world with the competence of building most of the current vessel types while maintaining high production efficiency. But in terms of

green shipping, China is still lagging behind Japan and South Korea. On the one hand, Japan and South Korea are outperforming us in terms of the average energy consumption, material consumption and pollution emissions; on the other hand, we rely on our overseas partners’ design support for the high-tech and high value-added vessels. Furthermore, we have not yet totally localised the current equipment while the new generation of green equipment has come to the stage, which challenges us greatly.” For the above problems, Weng


Zhenping offers his insight by putting emphasis on green technology. “Our scientific research efforts should be concentrated on green vessel types, green power, and green supporting technology, and our manufacturing competence should be correspondingly developed. Green shipping can be nurtured out of the existing shipping industry cluster so that we can finish the transformation from size and tonnage


advantage to a technology-and-profit- driven pattern, thus finishing our transition from big manufacturer to competent manufacturer.” In his joint study with Wu Yousheng,


a member of the China Academy of Engineering, Weng Zhenping says that in the first instance to integrate green shipping systems through the optimisation of key technology in terms of vessel types, power, supporting equipment, manufacture, operation, maintenance and scrapping, we can reduce emissions of NOx and SOx by 90%, and CO2


by 30%. In the energy


conservation and emission reduction of new concept vessels, by developing optimised vessel types, utilisation of non-polluting and light-weight materials, and the recycling of resources, there can be a realisation of the goal to operate zero emission ships. In addition to developing vessels with


high-performance, improved Energy Efficiency Design Index (EEDI) and Energy Efficiency Operating Index
