Abstract
The relevant regulations of classification societies, national governments, IMO resolutions are included in the ship design and production process. However, it was noted that the shipyard does not include seaman’s experiential perception to a higher level, coming from specific requests and observations during the operation and maintenance of the ship. Such requests are based on good marine practice, for which the shipyards do not have a sufficient level of experience and feedback which leads to additional works and alterations to customer requests and expectations. Therefore, the authors in this paper propose a methodology for the implementation of the feedback from the exploitation of the ship with the purpose of improving the ship design and production process to reduce costs and to improve ship efficiency in exploitation. In the first part of the proposed methodology, the collection and analysis of feedback is made using the expert approach and the relevant documentation in order to identify the most common groups of remarks. Such analysis was used as an input within the adjusted QFD method for identification and ranking of those ship design and production processes that affect mostly on such remarks. Furthermore, the matrix of quality control is proposed within relevant sub-processes, and the guidelines for the remarks solving within ship design and construction process are defined. In this paper, the authors have primarily analysed outfitting and equipment related issues which are often emphasised as more critical to a ship hull structure production, though, structure issues are set for further research. Finally, a typical example of such guidelines implementation for improving the ship design and construction process is given.
