ZTT is proud to announce the successful launch of their cutting-edge self-propelled full rotation crane vessel, 'Zhongtian 39', on October 29, 2023.




The 'Zhongtian 39' is a wind power construction vessel that measures an impressive 215 meters in length and 51.8 meters in breadth. It combines exceptional transportation and construction capabilities, setting new industry standards.

Notable features of the 'Zhongtian 39' include:

The vessel has two main hooks: a full rotation 3500-ton hook and a fixed stern crane with a lifting capacity of 5,000 tons. This enables it to lift 3200-ton wind turbine foundations and 4500-ton topside modules of substations. Equipped with a MENCK 3500kJ hydro pile hammer, it is well-prepared for piling operations. Utilizing a DP-1 dynamic position system, the vessel ensures precise manoeuvrability within offshore wind farms. The deck can accommodate one complete jacket structure or two monopiles, each with a diameter of 10 meters and a length of 120 meters.

The 'Zhongtian 39' is a highly versatile vessel that can be used for various purposes. It is capable of constructing offshore oil platforms, erecting large cross-sea bridges, hoisting heavy structures, and salvaging large sunken ships and objects. In addition, the vessel can efficiently carry out essential tasks such as port loading, marine transportation, and foundation pile installation for all units of 10MW and above.



The 'Zhongtian 39' by ZTT will undoubtedly play a pivotal role in driving the progress of wind power and offshore construction projects, making a significant contribution to the sustainable development of the industry.
