Shanghai Zhenhua Heavy Industry (Group) Co., Ltd. built the “Dehe” salvage crane pipe-laying ship project for Yantai Salvage Bureau. The Yantai 5000T crane pipe-laying ship is the most difficult and technologically advanced ship undertaken by Zhenhua Company in the world. One of the marine engineering projects with the highest content. This project is a key investment project funded by the State Council and is currently the largest ship project invested in the salvage system of the Ministry of Communications. The ship is equipped with internationally advanced DP3 dynamic positioning, 10-point anchor positioning and 3,000-meter salvage functions. A large offshore engineering crane with a lifting capacity of 5000 tons for fixed cranes and 3,500 tons for full-slewing cranes is installed at the stern. At the same time, the ship is equipped with S-type pipe laying equipment and related underwater robot system interfaces. It is suitable for the rescue and salvage operations of underwater sunken ships and sunken objects. It has the ability to respond to emergencies, carry out the overall salvage of large-tonnage underwater objects, and quickly clear obstacles. It can also carry out large blocks, platform modules, and jackets at sea. Hoisting and hoisting of offshore engineering structures. At the same time, it has functions such as platform operation support and diving operation support.
The ship is a deep-sea development and construction ship with the main functions of offshore deep-water lifting, pipe laying, and underwater installation. The high-redundancy DP3 dynamic positioning system and 10-point mooring system enable it to meet the needs of deep and shallow waters worldwide. Lifting and pipe laying operations require that 398 people can be accommodated on the ship at the same time. At the same time, it enters the ABS/CCS dual class, with a total length of 199 meters, a molded width of 47.6 meters, and a molded depth of 15.0 meters. It is equipped with a DP3 dynamic positioning system, a 10-point anchoring positioning system and a pipe laying system.
The “Dehe” is the first cooperative project between Zhenhua Heavy Industry and Yantai Salvage Bureau. During the construction process, Zhenhua Heavy Industry and Yantai Salvage Bureau have both attached great importance to them. The project teams of both sides have overcome numerous difficulties and challenges and continuously improved communication. A deep friendship has been established with Mutual Trust. The smooth delivery of the project has laid a solid foundation for the in-depth and extensive cooperation between the two parties in the future.
