BREAKING NEWS: The world’s largest dual-fuel TSHD launched in China
A launching ceremony of the world’s biggest and China’s first dual-fuel powered trailing suction hopper dredger (TSHD) Xin Hai Xun took place in Qidong, east China’s Jiangsu Province, today.
With a liquefied natural gas (LNG) clean energy capacity of 15,000 cubic meters, the vessel (ordered by CCCC Shanghai Dredging) boasts a total length of 155.7 meters, a breadth of 32-meters, a depth of 13.5 meters, and a structural draft of 9.9 meters.
This is coupled with a large hopper capacity of 17,000 cubic meters.
Independently developed in China, the ship uses LNG clean energy as its primary power source. In the event that LNG filling conditions cannot be met, the vessel is equipped with a backup diesel power system.
The ship, built by Shanghai Zhenhua Heavy Industry Co., Ltd. (ZPMC), is also kitted with cutting-edge technology, and features China’s “one-key dredging” system.
This system enables the vessel to use the “dredging and driving in one” approach, facilitating “unmanned dredging” functionality under typical working conditions.
Scheduled for delivery in September 2024, the Xin Hai Xun will mainly be used for dredging, reclamation, and coastal maintenance projects within coastal ports and deep-water channels.

Hydropower — electricity generated by turbines capturing energy from moving water — was for many years the primary contributor of renewable energy to the U.S. electricity grid. Its growth was rapid into the 1970s, and since then has offered a stable supply of power, while a declining share of all generation. For many years, hydropower was seen as clean energy and an unalloyed good, but a greater understanding of the impact of dams on ecosystems and wildlife has led to the removal of some dams. As of 2019, hydropower trails wind as a renewable source of power generation.
