Sanhanggong 9, an 18,000-tonne lifting-capacity semi-submersible barge, was named and delivered on 12 February at Ningbo Port in China’s Zhejiang Province, marking its entry into the core fleet of CCCC Third Harbor Engineering Co., Ltd.
With an 18,000-tonne lifting capacity, the vessel is designed to transport and submerge 12,000-tonne concrete caissons for installation. It can also handle large offshore components such as wind turbine jackets, supporting multi-mission deployment across heavy marine transport, deep-sea engineering equipment mobilisation, and emergency response operations in complex sea conditions.
Independently designed in China, Sanhanggong 9 measures 105 m in length, 43.5 m in beam, and 7.5 m in depth. The barge incorporates a detachable stern tower configuration intended to improve operational flexibility.
For diving operations, the vessel is equipped with a one-button diving system and a box-type energy storage device. The company said the configuration improves energy utilisation, reduces energy consumption and exhaust emissions, and enables automated control of submerging and resurfacing procedures.
Following delivery, Sanhanggong 9 will be deployed to offshore construction work. CCCC Third Harbor Engineering Co., Ltd. said the vessel will strengthen equipment support for deep-sea engineering market expansion, enhance offshore engineering capability, and support major national strategic projects.
