VESSEL REVIEW | Jia Ruishun – Versatile crane vessel for Chinese coastal and offshore waters

China’s Jiangmen Hangtong Shipyard recently handed over a new crane vessel to local company Guangdong Jia Ruishun Marine Science and Technology.

Classed by China Classification Society, Jia Ruishun (嘉睿顺) was designed by Wuhan Jinding Ship Engineering Design as a non-self-propelled, double-bottom single-deck vessel.

The newbuild has all-steel construction, an LOA of 128 metres (420 feet), a beam of 40 metres (130 feet), a design draught of 4.8 metres (16 feet), a depth of 8.6 metres (28 feet), and a six-point anchoring system. The shallow draught will enable operation in inland and nearshore waters while the anchoring system will facilitate safe deployment in deeper offshore regions.

The bow meanwhile has four deckhouses with cabins for the 80-strong crew.

Suitable for construction and emergency response

The main deck crane is a fully rotating unit with a maximum lifting capacity of 2,200 tonnes. The crane has a maximum slewing radius of 80 metres (260 feet) and a maximum lifting height of 115 metres (377 feet) above the main deck.

The lifting height means the vessel can be used to install large offshore structures such as wind turbine generators and their associated components, though it can also support other activities such as bridge construction, salvage, and rescue.

The vessel adopts some of the latest engineering design concepts and advanced technical systems. It boasts an automatic load adjustment system and loader, which has excellent operational performance and reliability when performing full-swing lifting tasks.

The hull structure and towing stability are designed to permit operations in offshore navigation areas, and these attributes can be upgraded according to construction needs in the future.
