The world's largest! The first domestically produced dual fuel trailing suction dredger begins its dredging operation journey

On the evening of September 27th, the "New Sea Sturgeon", the first domestic and world's largest dual fuel power drag suction dredger with a capacity of 15000 cubic meters built by Shanghai Zhenhua Heavy Industry, sounded its horn and untied the cable at Zhenhua Qidong Offshore Port, and sailed to Yangshan Port in Shanghai for dredging operations, paying tribute to the 75th anniversary of the founding of New China with practical actions.

The "New Sea Sturgeon" has a total length of 155.7 meters, a width of 32 meters, a depth of 13.5 meters, a full load draft of 9.9 meters, and a maximum mud tank capacity of 17000 cubic meters, equivalent to six international standard swimming pools. The design adopts a streamlined hull made of welded steel with dual stern fins, equipped with dual propellers, dual rakes, dual guide pipes, dual engine one trailer two composite drive, dual fuel (light diesel and LNG), with a full deck, bow tower, and bulbous bow.

As the first domestically produced and world's largest LNG clean energy powered trailing suction dredger, this vessel is a culmination of the dredging field, achieving multiple pioneering innovations: it can switch between using liquefied natural gas and diesel fuel as power systems at any time, and LNG power related technologies fill the gap in clean energy use and green low-carbon aspects of dredging ships in China; Through the most advanced "power control center", the "one to two" composite drive mode is used to meet the power needs of ships in various working conditions such as navigation, dredging, mud throwing, and shore blowing; Meet the emission requirements of IMO Tier III of the International Maritime Organization, with significant characteristics such as "green, environmentally friendly, energy-saving, and safe". The ship's performance, environmental indicators, and technological level have all reached the international leading level; Equipped with the most advanced and intelligent "one click dredging" and "dredging driving integration" systems in China, the "unmanned dredging" function under typical working conditions has been achieved for the first time in China.

The ship is equipped with a comprehensive intelligent management platform, which integrates intelligent engine room, intelligent navigation, intelligent energy efficiency management and other systems. Through the integrated design, installation and control of the entire ship, the intelligent management level of the entire ship is effectively improved, making operation more convenient, construction more efficient, and navigation safer.

The "New Sea Sturgeon" is another "dredging tool" delivered by Zhenhua Heavy Industry after the "island building artifact" - Asia's largest and most advanced 6600 kW cutter power heavy-duty self-propelled cutter suction dredger "Tiankun". It is a pioneer in the operation of clean energy power ships in China's coastal areas, with a localization rate of over 90%. The ship's performance, environmental protection indicators, and technical level have reached the international leading level. After being put into operation, it is mainly used for dredging, reclamation, and coastal maintenance projects in coastal ports and deepwater channels.

The successful construction of the "New Sea Sturgeon" vessel has further strengthened the green background of high-quality development in the dredging industry, setting an example for promoting the development of new quality productivity, advancing dredging technology innovation, and improving and developing the LNG supply chain construction of ships.
