FKAB has secured a contract for the design of a 2,400m³ trailing suction hopper dredger (TSHD). The concept de- sign was developed by the Ministry of Transportation and Communication?s Kaoshing Harbor bureau, which will own and operate the vessels. The order was acquired by the Ch- ing Fu Shipyard. The company won the contract in compe- tition with three other Taiwan-based companies. The Ching Fu Shipyard has commissioned FKAB for the basic and de- tail design contract based on the company?s experience and international standing in the shipbuilding industry. In order to improve the dredger?s performance, FKAB will review the concept design and provide the complete basic design package to the shipyard. FKAB will also de- liver the detail design and related production drawings. In order to complete the commission swiftly and ef ciently, FKAB has chosen Nupas-Cadmatic as their CAD/CAM system for the project. FKAB is part of the Swedish Mattson Gruppen, which is an independent engineering company mainly active in the marine and shipbuilding industries. With of ces in both China and Sweden and over 50 years of experience, it has established itself as a reliable partner. To date FKAB has completed various dredging designs, ranging from back- hoes, split barges and trailing suction hopper dredgers. Hopper dredgers are designed at the of ces in Sweden as well as at FKAB?s Shanghai of ce. The Swedish of ce created the basic design drawings and the FKAB China of ce will carry out detailed and pro- duction design with Nupas-Cadmatic. FKAB has owned Nupas-Cadmatic licenses for some years, but up until now the Nupas-Cadmatic design work has been done at the Dalian (China) of ce. The Shanghai of ce will now use the licenses for the complete design and production engi- neering of the dredger. The power supply of the dredger will be provided by two MAN 6L21/31 1290kW main engines, three 6090AFM75 222kW auxiliary engines and a single CAT3512C 1118kW dredging engine. The power supply enables the vessel to dredge to depths of up to 25 meters. This is suf cient for its main task; clearing the Kaoshing Harbor (Taiwan), the fourth largest port in the world. Nupas-Cadmatic: Ease of UseFKAB chose Nupas-Cadmatic for the job based on its ease of use and intelligence. This combined with the open interface to other systems and the advantages of Nupas- Cadmatic?s eBrowser, convinced FKAB that Nupas-Cad- matic could reduce engineering hours used in develop- ment and production. This is particularly evident in this case as the Ching Fu shipyard also uses Nupas-Cadmatic. Since FKAB will carry out all the design and production engineering for the dual class BV & CR dredger, the de- signers will extensively use the 3D modeling and produc- tion information advantages of Nupas-Cadmatic. The company has successfully used the software on design projects and will continue to do so in the future.
