On May 9, the world's first 100,000-ton offshore floating oil and gas production unit float assembly operation was successfully completed in the southern waters of Dalian, Liaoning Province, and slowly dragged away from the operating waters under the escort of the "Haixun 0301" ship.

The assembly project is the world's heaviest and most difficult offshore engineering operation, with the participation of large engineering vessels such as Asia's largest unpowered deck barge "Haiyang Shiyou 229" and deepwater flagship "Haiyang Shiyou 691".

The assembled floating oil and gas production unit is divided into two modules, the upper module and deck support frame weigh 36,000 metric tons, and the lower module weighs 39,686 metric tons.

In order to do a good job in the safety and security of navigation of the offshore assembly operation of the project, the Dalian Maritime Safety Bureau intervened in advance, optimized the site selection of the project, and took into account the special needs of the project such as water depth, tides, and currents, as well as meteorological conditions, route distribution, and fishing vessels obstructing navigation, so as to optimize the assembly operation point for the construction unit, delineate the safe operation area, and ensure that the assembly operation meets the navigation safety requirements. The bureau has also established a special work class to track and strictly control the operation risk throughout the process, implement precise policies to ensure the safety of construction operations, and provide technical support for the safe, orderly and efficient development of the project.(This article is from the official website of Seetao www.seetao.com.
