大型高速圍網漁船之開發

Development of a Super Class High-Speed Purse Seiner

本文開發出滿足漁業界迫切需求之大型高速圍網漁船，以維持我國在遠洋漁業發展之優勢。在初步設計方面，首先廣泛蒐集類似船資料，利用迴歸公式快速擇定出適合的主要尺寸及漁艙容積。船型設計方面，應用了勢流分析方法進行線型擇優，並在台灣大學進行船模阻力推進試驗與實船紊流場計算，以驗證其速度性能。在一般佈置設計原則方面，在實務上通盤考量漁法、作業及艙間需求，並以人體工學為出發點，考量漁獲裝卸、搬運動線及住艙佈置等，以期達到發揮人的潛力，使人一機（船）系統整體效率達到最大值。 A high speed super class purse seiner was developed to meet the requirement of the Taiwan's fishery and maintain it's superiority in the pelagic fishing. In the basic design, the datas of similar purse seiners were collected firstly. Then, the regression method was applied to analyze the collected datas and to derive the empirical formulas. The principal dimensions of designed purse seiner were determined from the regression formulas. In the design of hull form, the potential computational fluid dynamics code was used to optimize the lines. Then, the model tests of resistance and self-propulsion were conducted in the towing tank of National Taiwan University to validate the designed propulsive performance. Also, the viscous flow field computation of full scale ship was done by Comet code to verify the nominal wake and wave patterns. The general arrangements of the purse seiner, such as the fishing method, operational and compartment requirements, the loading and unloading of fish, the moving path, and humanistic cabin, were designed based on the principles of human factor and ergonomics. The maximum efficiency of human-ship system was expected in this design by developing the human potential.
