Abstract

Many shipyards today have made technological changes to their production facilities over the past decades. However, the building methodology has remained the same. Implementing a lean manufacturing approach to shipyards requires analysis of the present shipyard facilities. Likewise, the lean compliance level needs to be measured. After this, the steps for lean transformation are determined. In this work, a case study of a shipyard with a traditional panel-block assembly process is transformed to a lean one which follows one piece fl ow. The integration of group technology, a product work breakdown structure (PWBS) and lean manufacturing yields optimal results illustrated through risk analysis. This is best demonstrated through the analysis of man-hours in assembling a typical shipbuilding block ready for erection.
