On March 3rd, the 14,000TEU dual-fuel container ship “Xinfu 90” built by Yangzi Xinfu successfully completed its trial berth at the Yangzi Mitsui in Taicang. The 8-day oil and gas test at sea was a success.
It is reported that the ship is the largest dual-fuel container ship completed and completed by Yangzijiang Shipbuilding Group. After the ship is delivered, it will be the first dual-fuel container ship put into operation by Mediterranean Shipping (MSC). The total length of the ship is 335.00m, the length between the two columns is 324.60m, the width of the ship is 51.00m, the molded depth is 29.90m, and the maximum draft is 7 meters. Since the maximum height above the keel is 73 meters, it is much higher than the navigation limit of Jiangyin Bridge. Through planning and research, the ship’s 5-story superstructure and part of the chimney were divided and placed on the hatch cover before the sea trial. On January 7, the giant ship was towed by 6 high-horsepower tugboats, forming a 665-meter towing formation, and safely sailed into the Yangtze River from Yangzi Xinfu to Yangzi Mitsui.
According to the command center of Taizhou Maritime Safety Administration, the towing operation is the longest and most difficult towing operation in the history of Yangzijiang Shipping. It has refreshed the historical record of navigation in the Yangtze River. In order to complete this towing operation, the Jiangsu maritime department invested 22 coast patrol boats, 4 security maintenance boats, more than 50 maritime law enforcement personnel, and set up 10 emergency tugboat standby points along the way to fully ensure the formation and navigation of towing vessels. Safe berthing.
Starting from January 8, leaders at all levels of Yangzi Mitsui, Greathorse International Ship Management (GISML), NK, C-LNG, CSSC Hengyu Energy, and other relevant personnel worked together to overcome the short time, heavy workload, and labor force. Due to the many impacts brought about by shortages and repeated epidemics, the company worked overtime to complete a large number of outfitting and commissioning work after re-installation and hoisting, LNG bunkering work, and equipment commissioning work, creating conditions for the trial sailing as planned.
On February 24, it was carefully maintained by the Taicang Maritime Safety Administration, and it went out to the river for a trial voyage safely. On March 3, the ship successfully completed the trial voyage and berthed at the Taicang Yangzi Mitsui Wharf, setting a record for the shortest trial voyage time for the same ship type in the industry.
The ship uses the world’s largest C-type fuel tank, selects the LNG low-pressure gas supply system first designed by C-LNG and the first 9X92DF main engine designed by WIN-GD to meet Tier III, the first largest single-chamber C-type tank as a super The fuel tank of the large container ship adopts clean energy LNG, which can reduce 99% of sulfur dioxide, 91% of particulate matter emissions and 92% of nitrogen oxide emissions, and the energy efficiency index meets EEDI, Phase III. Under the SMCR condition, the CO2 emission per hour of the main engine is reduced by 24.3% compared with the traditional fuel mode.
该船使用了全球最大的C型燃料罐，选用了C-LNG首次设计的LNG低压供气系统以及WIN-GD设计的首台9X92DF主机，满足Tier III, 首创最大单气室C型罐作为超大型箱船的燃料舱，采用清洁能源LNG，可减少99%的二氧化硫，91%的颗粒物排放和92% 的氮氧化物排放，能效指数满足EEDI，Phase III。主机在SMCR工况下，每小时CO2排放量相对传统燃料模式下降24.3%。
