Recently, Shenda Hao, China's new-generation deepwater pipelaying vessel, was officially commissioned into service with the Shanghai Salvage Bureau of the Ministry of Transport of the People's Republic of China. Fitted aboard this 40,000-ton class deep-sea work vessel, the controllable passive tank stabilizer — independently developed and manufactured by Hunter Marine as core supporting equipment — delivers critical support for the vessel's operational safety and stability in harsh sea conditions.
Shenda Hao has an overall length (LOA) of 177.1 meters and a full-load displacement of 40,000 tons, making it a new-type deep diving support vessel independently designed and built in China. Deepwater pipelaying and emergency salvage and rescue operations impose extremely stringent requirements on hull stability. The controllable passive tank stabilizer supplied by Hunter Marine for this vessel is precisely the critical link that guarantees its deep-sea operational capability.
As the only specialized marine roll stabilization enterprise in China integrating independent design, manufacturing and full-cycle services, Hunter Marine has equipped its independently developed controllable passive tank stabilizer with two core technical highlights:
Technically, it integrates the superior advantages of both passive and active tank stabilizers. This device can operate effectively regardless of whether the vessel is navigating at low or high speeds, and delivers highly efficient suppression of hull roll.
By precisely controlling the phase difference of the water mass inside the tank stabilizer, it generates reverse anti-roll moment, significantly reduces the hull roll amplitude in complex sea conditions, and provides a stable offshore working platform for deepwater pipelaying, salvage and other operations.
The successful delivery of Shenda Hao is an important practice in China's advancement of the construction of a leading transportation nation. As the core technical supporting unit for the vessel, Hunter Marine has fully demonstrated its profound technical accumulation and innovation capability in the field of marine roll stabilization.
