Research On Equipment Building Technique Of Large-Scale Suction Dredger Vessel

The paper focuses on the present dredger vessel building technique couldn't be satisfactory to the requirements of domestic markets. Comprehending and command the technique property of main equipments to large-scale dredger vessel such as big diameter suction channel doors, big diameter suction tubes and the sling systems etc. Base on the technique experience of building large-scale suction dredger vessel in shipyard, put forward the technology procedure of specific manufacture technology processes, control technique of precision and the technique of installed on vessel by the way to the technique of analysis the structure characteristic suction channel doors, suction tube and sling system, research key construct technique. At the same time succeeded apply on real vessel. The experiences are accumulated for shipyard to research dredger vessel equipment for the future.The main research works and conclusions of the paper:(1) The article researches facture and fitting technology technique of bottom doors, suction tubes and suction tube hangers. Analysis the key building technique of control accuracy degree and welding technology etc. Marking good regulations of the technology technique.(2) Accumulates the experience for shipyard to research dredger vessel equipment for the future through research the key building technique and technology technique which have succeed apply on the real vessels. And also win the good economic benefit for the shipyard.
