2、ip design The term basic design refers to determination of major ship characteristics affecting cost and performance. Thus, basic design includes the selection of ship dimensions, hull form, power (amount and type), preliminary arrangement of hull and machinery, and major structure. Proper selection

Furthermore, it includes checks and modifications for achievement of required cargo handing capability, quarters, hotel services, su

Basic design encompasses both concept design and preliminary design. It results in the determination of major shop characterist

Contract design, as its name implies, develops plans and specifications suitable for shipyard bidding and contract award. Well prepared contract pla
6、ns and specifications will be clear and in sufficient detail to avoid costly contingency items and protect bidders from obscure or inadequate description of requirements. Detail design is the shipyards responsibility for further developing the contract plans as required to prepare shop drawings used
7、 for the actual constructions of the vessel. An understanding of the entire design sequence is essential to anyone seeking to develop a basic design. The four steps involved are illustrated in the Design spiral,Evans(1959) as an iterative process working from mission requirements to a detail design,
8、 Fig.1.1. These steps are amplified further below: a. Concept design The very first effort, concept design, translates the mission requirements into naval architectural and engineering characteristics. Essentially, it embodies technical feasibility studies to determine such fundamental elements of t

The selected concept design then is used as a talking paper for obtaining approximate construction costs, which often determine whether o

Contract design The contract design stage yields a set of plans and specifications which form an integral part of the shipbuilding contract document. It encompasses one or more loops around the design spiral, thereby further refining the preliminary
