xinmin evening news (reporter ye wei, correspondent he baoxin, duan xueqiong) recently, one of the most influential german hamburg maritime exhibitions (smm) in the world opened at the hamburg international exhibition center. five high-quality ship types independently developed and designed by china shipbuilding industry corporation's china ship and marine engineering design research institute (maric), including the 150,000 cubic meter ultra-large liquid ammonia carrier (ulac) and the 16,000teu ammonia-fueled large container ship, received the approval in principle (aip) certificates issued by internationally renowned classification societies, which attracted widespread attention in the industry and demonstrated maric's strong innovation capabilities and leading effect in the field of green and low-carbon ship research and development.
the 150,000 cubic meter 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 the norwegian classification society (dnv). the ship has a total length of 278 meters and a beam of 44 meters. it uses a type a independent liquid cargo tank with a cargo tank volume of 150,000 cubic meters. the ship is equipped with an lpg dual-fuel main engine and has reserved the ability to use ammonia fuel, which can meet the most stringent emission requirements while maintaining the best economy. it adopts the upright bow line type independently developed by maric, and further improves the rapidity index by adopting energy-saving devices. in addition, this ship type also meets the latest effective network security requirements.
maric's independently developed new generation hercules 16000teu ammonia fuel-powered large container ship has been awarded the aip certificate by china classification society (ccs). the ship is equipped with an independent b-type ammonia tank with a capacity of 16,000 cubic meters. its cruising range can support one-way voyages on the asia-europe route and other mainstream routes in the world. by using ammonia as ship fuel and combining it with exhaust gas treatment technology, the emissions of sulfur oxides and nitrogen oxides can be significantly reduced, and zero carbon emissions can be achieved.
the 20,000 cubic meter ammonia fuel bunkering ship has obtained the aip certificate issued by china classification society (ccs) and lloyd's register (lr). the ship is 157.9 meters long and 25 meters wide, and can be used for ammonia fuel bunkering operations in major ports around the world. the ship type scheme adopts two single-cylinder c-type cargo tank schemes for breakthrough, which has a series of advantages such as lower boil-off rate (bor), more flexible boil-off gas (bog) management, higher tank capacity utilization, fewer domes (dome), higher safety and reliability, and simpler operation. three manifolds and two folding arm cranes are set up to match different scales of receiving ships in a wider range. the hull lines of this ship have been deeply optimized. while having ultra-high fuel (gas) efficiency, the flat sideline range is expanded as much as possible, so that fenders can be arranged in a wider range and the bunkering matching capability can be improved. the ship is also equipped with ammonia leak detection, ammonia capture, nitrogen oxide (nox) and nitrous oxide (n2o) catalytic reduction systems. it is a green and environmentally friendly ammonia fuel bunkering ship with large single bunkering volume, good ship type matching, good maneuverability, high reliability and excellent economy.
the 82,000 cubic meter ammonia fuel bulk carrier has obtained the aip certificate issued by the french bureau of shipping (bv). the ship is the largest single-propeller-driven ammonia fuel-powered kamsar-type bulk carrier, suitable for global navigation. the ship is equipped with two c-type tank ammonia fuel tanks, which are arranged on both sides of the superstructure. the fuel preparation room is arranged in the area below the fuel tank. the ammonia filling station is arranged in the cargo hold area. it is an open structure and a protective device is installed to prevent cargo from falling and being damaged. the total volume of the fuel tank is about 3,200 cubic meters. the economic speed endurance in gas mode can reach 19,000 nautical miles. at the same time, a larger fuel tank is retained, and the endurance in fuel mode exceeds 23,000 nautical miles. an open scrubber is used as an alternative to reduce fuel costs. in addition, the ship is integrated with an intelligent system that can provide assistance to ships in route planning, energy consumption monitoring and ammonia fuel system monitoring.
the largest suez product tanker powered by ammonia fuel with a deadweight of 162,000 tons has been awarded the aip certificate by the american bureau of shipping (abs). the ship is 274 meters long, 50 meters wide, and has a structural draft of 17.15 meters. the ship is single-engine and single-propeller propulsion, and the propulsion main engine is an ammonia dual-fuel main engine, which meets the requirements of unlimited navigation areas. the ship's ammonia fuel tank is semi-cold and semi-pressurized, and the main deck is equipped with two c-type independent ammonia fuel tanks made of carbon manganese steel, with a cruising range of up to 12,000 nautical miles. in addition, the ship has the characteristics of low fuel consumption and high cargo capacity, and adopts a variety of energy-saving measures, including upright bulb bow line optimization, energy-saving devices, large-diameter propellers, etc., and is equipped with shaft-belt generators.
as a pioneer in the field of research, development and design of chinese civil ships, maric focuses on "green, intelligent and low-carbon" and digital technologies, and continues to tackle key technologies such as green ships, intelligent ships and polar ships. it has successively launched a full range of dual-fuel container ships, bulk carriers, oil and chemical ships, gas carriers and other ship solutions, and continues to optimize and iterate.
