On September 3, one of the most influential in the world, the Hamburg Marine Exhibition (SMM) in Germany opened. The 150,000 cubic meter liquid ammonia carrier (ULAC) and the 16,000 TEU ammonia fuel-powered container ship independently developed and designed by China Shipbuilding and Offshore Engineering Design and Research Institute (MARIC), a subsidiary of China State Shipbuilding Corporation (MARIC), have respectively obtained the Approval in Principle (AiP) certificate issued by internationally renowned classification societies, which has attracted wide attention in the industry and demonstrates the strong innovation ability and leading role of MARIC in the field of green and low-carbon ship research and development. Lu Lin, President of MARIC, and senior leaders of the headquarters of five internationally renowned shipbuilding classification societies attended the certificate awarding ceremony.
The 150,000 cubic meters liquid ammonia carrier (ULAC) is a new generation of extremely large liquid ammonia carrier independently developed by MARIC, and has obtained the AiP certificate issued by DNV. The ship has a total length of 278 meters, a width of 44 meters, and a type A independent cargo tank, with a cargo hold volume of 150,000 cubic meters. The vessel is equipped with an LPG dual-fuel main engine and is reserved for the use of ammonia fuel, which can meet the most stringent emission requirements while maintaining the best economy. The upright headline type, developed in-house by MARIC, has been adopted to further improve the speed index by adopting an energy-saving device. In addition, the vessel meets the latest cybersecurity requirements in force.
HERCULES series 16000TEU ammonia fuel powered container ship has been awarded the AiP certificate issued by China Classification Society (CCS). The vessel is equipped with an independent Type B ammonia tank with a capacity of 16,000 cubic meters, and its endurance can support one-way voyages on Asia-Europe routes and other mainstream routes in the world. By using ammonia as a marine fuel in combination with exhaust gas treatment technology, it is possible to significantly reduce sulfur oxide and nitrogen oxide emissions and achieve zero carbon emissions.
The 20,000 cubic meter ammonia bunkering vessel was awarded the AiP certificate by China Classification Society (CCS) and Lloyd's Register (LR) of United Kingdom. With a length of 157.9 meters and a beam of 25 meters, the vessel is suitable for ammonia bunkering operations in major ports around the world. The ship-type solution is a breakthrough with two single-cylinder C-type cargo tanks, which has the advantages of smaller evaporation rate (BOR), more flexible BOG management, higher capacity utilization, less DOME, higher reliability and simpler operation. With three header areas and two knuckle boom cranes, it can match a wide range of different sizes of injected ship types. The hull line of the ship has been deeply optimized to have ultra-high fuel (gas) efficiency while expanding the range of flat edge lines as much as possible, so that a wider range of bump pads can be arranged to improve the filling matching ability. Equipped with ammonia leak detection, ammonia capture, NOx and N2O catalytic reduction systems. This ship type is an ammonia fuel bunkering ship with large single bunkering volume, good ship type matching, good maneuverability, high reliability, excellent economy and green environmental protection.
The 82,000 dwt ammonia fuel bulk carrier received the AiP certificate issued by the France Bureau of Shipping (BV). The vessel is the largest bulk carrier of the ammonia-powered Kamsar with a single propeller drive and can be used for global voyages. The ship is equipped with 2 C-type tank ammonia fuel tanks, arranged on both sides of the upper building; The fuel preparation room is arranged in the area below the fuel tank; The ammonia filling station is arranged in the cargo hold area, which is an open structure, and protective measures are set to prevent the goods from falling and being damaged; Breathable masts are placed in the bow area. The total volume of the fuel tank is about 3,200 cubic meters, and the endurance of economic speed in gas mode can reach 19,000 nautical miles, while retaining a large fuel tank, the endurance of fuel mode is more than 23,000 nautical miles, and the open scrubber is used as an option to reduce fuel costs. In order to improve fuel economy, install energy-saving devices, inverter pumps, fans, and LED lights; In addition, the vessel is equipped with intelligent systems that can assist the vessel in route planning, energy consumption monitoring and ammonia fuel system monitoring.
The 162,000 dwt ammonia-fueled Suezmax product tanker was awarded the AiP certificate by the United States Bureau of Shipping (ABS). The ship has a length of 274 meters, a beam of 50 meters and a structural draft of 17.15 meters. The ship is single-engine single-propeller propulsion, and the main engine of propulsion is ammonia dual-fuel main engine, which meets the requirements of unlimited navigation area. The ship's ammonia fuel tank is semi-cooled and semi-pressurized, and the main deck is equipped with two C-type independent liquid tanks made of carbon-manganese steel, each with a capacity of about 3,000 cubic meters. It has a range of up to 12,000 nautical miles. In addition, the vessel has the characteristics of low fuel consumption and high cargo capacity, adopts a variety of energy-saving measures, including upright ball headline optimization, energy-saving devices, large-diameter propellers, etc., and is equipped with shaft generators.
As the pioneer of China's civil ship R&D and design, MARIC has always stood at the forefront of ship science and technology, adhering to the concept of scientific and technological innovation, focusing on "green, intelligent and low-carbon" and digital technology, continuing to carry out key technology research such as green ships, intelligent ships and polar ships, and successively launching a full range of ship type solutions such as dual-fuel container ships, bulk carriers, oil-chemical ships, and gas carriers, and continuing to optimize and iterate. MARIC will continue to closely track the development of the latest energy-saving and emission reduction technologies, ammonia/methanol/hydrogen/nuclear power and other new fields and technologies, and continue to deepen the research of key systems and technologies such as equipment technology system, overall conceptual scheme, energy-saving and emission reduction technology, and alternative fuel propulsion, so as to make unremitting efforts to lead the high-quality development of innovative shipbuilding technology in the mainland shipbuilding industry.
