Green ship low carbon response strategy

2. The independent development ability of green ship supporting equipment and technology cannot meet the demand

The technical capability and environmental performance of ship supporting equipment greatly affect the "green" level of the entire ship industry. In recent years, a new generation of energy-saving, emission-reduction, low-noise green ship power, supporting mechanical and electrical equipment, ship environmental protection equipment and materials have been launched, becoming the mainstream trend of Marine energy-saving technology in the world, and promoting the development of emerging green ship technology and industry [19]. However, China has not yet carried out systematic research in the field of key supporting technologies for ship energy conservation and emission reduction, and scientific research forces in the directions of high efficiency and energy conservation, vibration and noise reduction, energy conservation and emission reduction, and new materials have not formed a joint force, and "skirmding" has led to small research forces and weak integrated innovation capabilities, making it difficult to achieve efficient transformation of scientific research results into productivity. The core technologies of some of the core supporting equipment of green ships, such as dual-fuel engines and thin-film envelope systems, still rely on foreign patent owners. Moreover, the green transformation of the shipping industry requires enterprises to make a large amount of investment, and the rise in operating costs may weaken its original market competitive advantage, which will affect the enthusiasm of enterprises to participate in the green reform of the shipping industry. In the context of increasing Sino-US trade friction, it is urgent to consider and solve the problem of breaking through the key supporting equipment and "blocking neck" technology of China's green ships as soon as possible, forming the ability of independent development, and building a healthy internal cycle of the green ship industry.

3. Green ship technology innovation and standards to lead the lack of power

Norway, Japan, the United Kingdom and other countries attach great importance to seize the international leading technology plateau with tight time arrangement and efficient technology research and development when formulating the development plan of green ships, so as to participate in the formulation of relevant standards and norms of international organizations and highlight their own voice. In terms of technology research and development, emphasis is placed on green design and innovation from the aspects of new alternative fuel, hull optimization design, green power propulsion, etc. Although China's green ship research and development and construction have made breakthroughs in some fields, but on the whole has not reached the international advanced level; The initiative of independent innovation of green ship design technology under the international Ship Energy efficiency Design Index is insufficient. Most of them are forced to meet the pressure of international conventions, new codes and new standards, through additional energy saving and emission reduction equipment and improvement based on the existing ship framework structure, and lack of pioneering green ship design concepts.

Second, countermeasures and suggestions

As an important participant in the United Nations action on climate change, China put forward its carbon emission reduction target for 2030 at the Paris Climate Change Conference in 2015. The development of green ships is an important way to practice international emission reduction commitments, and also an important opportunity to promote the transformation and upgrading of China's shipbuilding industry. 2020-2030 is the key period to accelerate the breakthrough of green ship core technology, only by fully grasping this key window period, can we prepare for the realization of green ship marketization and industrialization after 2030. It is recommended to plan the development strategy of green ships as soon as possible from the national and industry levels, reverse the situation of passive following, imitation, and import if it cannot be made, and fully evaluate the basic conditions in the field of domestic green research and development and manufacturing at the same time, give full play to the advantageous resources and strength at home and abroad to make breakthroughs in key "jam neck" technologies.

(1) Strengthen government leadership and formulate national and industry-level green ship development plans

1. Guide development direction with policy planning and promote resource integration

Green ships are an important opportunity for China's shipbuilding industry to enhance international competitiveness and ensure sustainable development. We should base on the development needs of the shipbuilding industry, benchmark domestic and foreign carbon emission reduction targets, establish the strategic position of green ship development from the national and industry level as soon as possible, and formulate a systematic and operable green ship development plan. Promote and guide the integration and utilization of research forces and resources of relevant domestic enterprises and research institutes with policy planning, reduce repetitive and low-quality inputs, focus on key development directions, and accelerate the breakthrough of the core key technology system of green ships.
