於船舶初步設計中，船型設計為決定船舶性能中重要的一環。理想的船型設計方式，是探討船型幾何變化對於船舶性能上的影響。於船型幾何的改良中，船型主要目及參數的選定對於推進性能上的影響，通常無法以線圖修改就可以補償的。所以目前船型設計的方式，以船型參數選定設計，用來決定產生船型幾何。利用船型變移方式得到船型資料，並對於船型幾何加以分析與改善以得到符合需求之船型資料。
目前資訊系統與網路通訊系統的進步，使得船舶設計能夠以協同專案設計的方式進行，達到設計流程分工與資訊分享，進而加速船舶設計時程。以網路資訊科技來提升船型設計的資訊管理方式，導入採用中性資料標準格式的船型資料格式，建立操作容易且包含設計歷史紀錄的船型資料庫，將可以縮短船型設計時間並可充分利用船舶設計資料。
本研究以網路運算技術的方式，來改善傳統船型設計流程的設計架構，以協同專案設計的方式進行船型參數化設計。利用船型參數變移方式得到船型幾何資料，並對於船型截面幾何加以傅利葉級數分析，作為船型變移基準以達到符合設計目標之船型。將其設計流程與結果結合目前資料傳遞文件XML的資料格式，作為其他計算流程之資訊交換。以專案管理方式將船舶資料加以管理。藉由網路協同專案設計，即可用於不同地點或其他平台上，促使設計知識分享，提升其設計競爭能力。

The conceptual design of optimal ship hull forms involves investigating the effects of hull geometry variations on hydrodynamic performance characteristics. The selection of the principal dimension and hull form parameter involves the hydrodynamic performance. In the ship design processes, generate hull form to get offset table data by selecting the principal dimension and hull form parameter. However, traditional hull form design which ship designer complete design is compact and difficult.
Due to the high-speed development in information technology and internet, designers use new technology to improve the information management of the conceptual design. An easily accessed hull form design database containing performance data on a wide range of previous designs can shorten the time required during early stage design to achieve the hydrodynamic performance goals of a given design.
So in this Project, we try to apply network computing improve traditional hull form design. A survey of existing and proposed hull form design systems worldwide suggests that the development of standardized neutral formats for digital data exchange would greatly improve the ship designer’s access to a wide range of existing hull geometry/ship performance data. Analysis Fourier Descriptor to improve hull geometry and ship performance .Using XML Standard for store hull geometry/ship performance data into hull form database. We express the same application will be extended to share design knowledge at anytime in anywhere.
