ABSTRACT

The operational costs of ship recycling yards will increase since the new regulations require more stringent standards for preserving the occupational and environmental health and safety of the people involved in recycling activities. Improvement of the current operational procedures and current levels of productivity will be critical to survive in a competitive industry dominated by low-cost substandard yards. The main aim of this study is to increase the productivity of the yards through the improvement of processes. In this study, cutting operation in the secondary zone is investigated using discrete event simulation. Alternative cutting technologies have been tested in a simulation to assess their impact on production performance and operating costs. This study shows that plasma cutting is a good alternative to oxyfuel cutting. Overall research conducted in this study is significant contribution to the literature as a novel approach for modelling processes and for the implementation of cutting technologies.

摘要

由于新法规要求更严格的标准来维护参与回收活动的人员的职业和环境健康与安全，船舶回收场的运营成本将增加。改进当前的操作程序和当前的生产力水平对于在由低成本不合格码场主导的竞争性行业中生存至关重要。本研究的主要目的是通过改进流程来提高堆场的生产力。在这项研究中，使用离散事件模拟研究了次要区域的切割操作。替代切割技术已在模拟中进行了测试，以评估它们对生产性能和运营成本的影响。这项研究表明，等离子切割是氧燃料切割的良好替代品。
