Abstract

Shipbuilding industry is considered to be a thrust sector in the economy of Bangladesh. In the shipbuilding process, CNC cutting is used to cut steel plates according to the ship design. The objective of this thesis is to measure the performance of the CNC section. To do this, Overall Equipment Effectiveness (OEE) is selected; a tool of Lean Manufacturing widely used to measure the efficiency of a manufacturing plant in terms of availability, performance and quality and also identify the major productivity losses. Data were collected from the CNC shop to calculate the OEE percentage. The amount of three OEE losses i.e. downtime, speed loss and quality loss was measured and the liable factors behind these losses were identified. It is found that the Overall Equipment Effectiveness of CNC cutting section of Western Marine Shipyard Ltd. is 35.01%. Finally, some recommendations were given to improve efficiency of the CNC section by eliminating these factors.
