6.2.3 Features of Ship as a Product Traditionally product development procedure starts with initial design of a product and stops at completion of its manufacturing [Storch et.al 1995]. However in shipbuilding context, product development t is a continuous process which extends Table.6.1 Major Outcomes of the proposed Design for Recycling on End-of-Life Activities Elements Design for Recycling • Development of knowledge base on components/equipme nt • Implementation of product standards such as modular design, unit assembly • Efficient access, lighting and ventilation plan • Reduction of total number of dissimilar equipment/componen ts. • Minimize use of hazardous materials. • Design proper layout for machines / equipment/ components • Coding of components and equipment • Develop recycling plan Stages of Product development Preliminary design Detailed design, purchase and construction Detailed design and construction Preliminary design and detailed design Detailed design Detailed design and construction 118 Primary Outcome Secondary outcome Easy reuse Easy dismantling process Smooth recycling pre processing Efficient and ecofriendly recycling Easy dismantling by adjusting connection tolerances & working space. Identification of potential reusability of onboard materials and systems Design for recycling document Efficient and safe handling of parts Mass purchase & efficient storage Support for after sales logistics No legal tangles Efficient administration Trouble free operations in other life cycle stages Replacements and modification are made
well beyond the new shipbuilding activity. Ships when compared with other industrially designed and manufactured products are quite extraordinary in a sense that the four stages in life cycle of ships viz., design, production, operation and dismantling which are to be examined in detail to arrive at a comprehensive life cycle system. Each of these stages has more than one sub stage and these stages have an influence over the product development. The unique characteristics of product development of ships have been identified by Sivaprasad [1993] and are listed below: a. One off kind product status b. Active customer involvement c. Multi functional product design attributes d. Multi user product requirements e. Extensive and sometimes contradicting rules and regulations f. Proactive presence of classification and statutory agencies g. Longer life cycle h. Extensive repair and modification requirements These characteristics together with the massive and complex nature of ships make them a vast engineering product. 6.2.4 Review of the Life Cycle Stages of Ships Among the four life cycle stages mentioned earlier thrust is given on operation part, since it is the only life cycle stage with financial profit. Ship is over utilized as a transport mechanism and generally profit maximization is the motivation behind this. Traditionally shipbuilding is a customer driven industry and the involvement of ship owner in design and development of the product design is more dominant compared to any other engineering products [Sivaprasad 1993]. In earlier periods, the naval architects and ship designers did not consider disposal of a ship as one of the life cycle stages as it did not figure in the owners requirements. Alkaner et al 2 [2006] have stressed the requirement of incorporating ship recycling as one of the important life cycle stages in shipbuilding and the model proposed by him can be represented as given in fig.6.1 Design Spiral Construction Operation Fig 6.1 Modified Model of Life Cycle Stages of Ships Alkaner [2006] 119 Repair & Maintenance Recycling
