The first domestic dual-fuel powered trailing suction dredger with a cabin capacity of 15,000 square meters, the "Xinhai Sturgeon" successfully completed its sea trial

According to news from this site on September 1st, on August 30th, China’s first 15,000-square-meter dual-fuel powered rake-suction rake-suction vessel was invested by CCCC Shanghai Shipping Bureau, general contractor of CCCC Dredging Technology Research Center, and built by Shanghai Zhenhua Heavy Industry The dredger "Xinhai Sturgeon" returned from its trial voyage and successfully completed its LNG gas trial mission.

According to Shanghai Zhenhua Heavy Industry, the dual-fuel power design of the "Xinhai Sturgeon" has filled the gap in domestic clean energy dredgers. As the first dual-fuel powered dredger in China, LNG clean energy is the main power source. Its LNG ship power plant has basically the same power performance indicators as diesel engines, while reducing nitrogen oxides by 90% and carbon dioxide emissions by 20%. This vessel is equipped with the most advanced and intelligent “one-click dredging” and “dredging and driving” systems in China, realizing the “unmanned dredging” function under typical working conditions for the first time in China .

This LNG gas power trial successfully carried out the main engine and auxiliary engine fuel and gas switching test, the main engine endurance test in gas mode, the DP (ship dynamic positioning) function test, CPP (controllable pitch propeller) and its control Tests, as well as many important test projects such as dredging and bow blowing in gas mode, all key equipment and system indicators are excellent.

According to inquiries on this site, on December 24, 2023, the "New Sea Sturgeon" ship built by Zhenhua Heavy Industry, invested by China Communications Construction Company Shanghai Shipping Bureau and general contracted by the Dredging Technology Research Center, was launched in Qidong, Jiangsu. It is expected to be officially delivered in September 2024 and will be mainly used for dredging and coastal maintenance projects in coastal ports and deep-water channels.
