Green eco-ships to become the mainstream trend of future development
Under global ecological, resource and environmental pressures, the international community has tasked the International Maritime Organization (IMO) with introducing a number of measures to curb greenhouse gas emissions from shipping, alien biological transfer, air pollution prevention, and marine plastic waste management. Green and ecological development has become an inevitable trend in the subsequent development of shipping and shipbuilding. It will be one of the focuses of future international policy and technical standards, and an important direction for future research and development and the application of new technologies.
“Green eco-ships”, taking safety as a prerequisite and environmental protection as a main target, putting ship energy efficiency at its core, recycling and crew working environments as auxiliary functions to further reduce the ecological impact on the ship’s operating environment, will inform ship safety, energy conservation, environmental protection, comfort and sustainable development levels, and will form the mainstream trends of future vessel development.
In addition to retaining the original green elements, the latest “Rules for Green Eco-ships” released by the China Classification Society (CCS) adds new “ecological” elements, incorporates the concept of circular and sustainable development, and uses low-carbon/zero-carbon green innovative technologies as the important support. These Rules will lead the healthy development of shipping toward a green, ecological and sustainable direction, and help CCS fulfill its social responsibility to serve shipping and promote energy conservation and emission reduction.
Providing solutions for the LNG water application industry chain
Preventing air pollution from ships drives the shipping industry to adopt advanced technologies to reduce emissions from ships. The new emission reduction technology using LNG fuel is being applied more broadly.
CCS promotes and guides the healthy development of LNG applications on water, and works closely with government authorities, energy companies, and universities and colleges to do research covering the entire industrial chain of LNG from transportation, bunkering to utilization. CCS has provided classification services for LNG powered ships, LNG bunkering pontoons, LNG mobile bunkering ships, and LNG transport ships newly built in China. With continuous technology accumulation and attention paid to customer needs, CCS provides customers with an integrated solution to each link in LNG application.
Promoting the application of pure battery power on ships
CCS began to study the rules and standards for the use of lithium-ion batteries on ships around 2010, and provided technical support for many new energy ships, including solar photovoltaic + lithium iron phosphate battery catamaran sightseeing ship on Yundang Lake of Xiamen, conversion project of a large car ro-ro ship, “COSCO TENGFEI” (adding solar photovoltaic system and lithium iron phosphate battery), 98-seat dual-power pure electric sightseeing ship on Suzhou River etc. Based on the research results, CCS formulated and issued the relevant standard “Guidelines for the Survey of Solar Photovoltaic Battery System and Lithium Iron Phosphate Battery System”. In order to provide better technical services for battery-powered ships, we have also been committed to the research work of relevant technical standards for pure battery-powered ships since 2018 and have issued “Guidelines for the Survey of Pure Battery-powered Ships”. At the same time, the relevant statutory requirements for lithium iron phosphate batteries have been included in the “Technical Rules for the Statutory Survey of Small Inland Ships” (2019 Amendment) and the “Technical Rules for Statutory Survey of Inland Ships” (2019).
At present, a complete standard system has been formed for electric ships powered by lithium iron phosphate batteries from the level of regulations, rules and survey guidelines, which can provide a basis for the design, plan approval and survey of the industry. Other batteries represented by ternary lithium batteries can also be used to provide services to the industry in accordance with the Guidelines for the Survey of Pure Battery-powered Ships of CCS.
