According to China Shipbuilding Industry Association (CANSI), this is the “world’s first” fifth-generation Changheng Series 174,000 cubic meter large-scale LNG transport ship. The LNG carrier will work for China’s energy giant CNOOC.
Compared with the previous generation ship, the new vessel’s carbon emissions for a single day’s voyage are estimated to be curbed by more than 10 tons. Adopting the WinGD 5X72DF2.1 dual-fuel main engine installed with the intelligent control exhaust gas recirculation ( iCER ) system technology, the vessel is said to be the first ship of the ‘CNOOC mid- and long-term FOB resource supporting LNG carrier project.’This is divided into two phases, building 12 LNG ships of 174,000 cubic meters in total. If these ships are put into operation, about 7 million tons of LNG will be transported back from all over the world every year, which is estimated to have the potential to meet the needs of 54 million families for nearly a year.
The Lv Neng Ying LNG ship is perceived to be an important piece of China’s plan to ensure the safety of energy transportation, improve the independent controllability of its LNG transportation industry chain, lending a helping hand to the country in building up its manufacturing and maritime power. Hudong-Zhonghua has undertaken a total of 34 Changheng Series LNG carriers so far.
With LNG tanks fitted with GTT’s NO96 Super+ containment system, the evaporation rate is expected to be 15% lower than the previous generation L03+ system, reaching a boil-off rate of 0,085% V/d, which is anticipated to provide a wider range of oil and gas balance speeds for low-carbon navigation intervals.Given the weight of previous generation vessels, the new LNG carrier of 174,000 cbm is said to have lost more than 1,500 tons of weight, but comes with a higher cargo hold loading rate and can load 800 cubic meters more LNG per voyage.
As outlined by CANSI, the vessel can be equipped with an optional reliquefaction system of 1.5 to 2.3 tons, which can adapt to the various balanced utilization requirements of evaporation gas in different routes, such as short-distance, medium-distance, and long-distance.
