Accuracy Control In Hull Construction of Ships - A Case Study

摘要

Accuracy control can be defined as the use of statistical techniques to monitor, control and continuously improve shipbuilding design details, planning, and work methods so as to maximize productivity. Accuracy Control essentially is based on the basic fact that there is no such thing as absolute accuracy. A study on the implementation of Accuracy Control System was carried out in a shipyard. To achieve this high degree of unit accuracy, the guidelines for systematically monitoring the production process was set. For implementation of accuracy control system, it is necessary to have an accuracy control data base. This gives the statistical history of the accuracy of the work processes employed. It is the quantitative measure of normal performance at every work stations. Each piece of data in accuracy control data base is associated with a particular work process. Based on these findings, a proposal was recommended to the shipyard on how Accuracy control system (ACS) can be initiated. It is inferred that with these recommendations, the quality of ship produced can be improved along with reduction in production cost and thereby increased competitiveness. After implementation a pilot study was conducted to ascertain the benefits accrued in the sub assembly area of Hull fabrication from the introduction of accuracy control. The present work focuses on implementation of Accuracy control in plate preparation stage in hull fabrication of Ship building.
