To prevent pollution from ships, the Energy Efficiency Design Index (EEDI) is a mandatory guideline for all new ships. The Ship Energy Efficiency Management Plan (SEEMP) has also been applied by MARPOL to all existing ships. SEEMP provides the Energy Efficiency Operational Indicator (EEOI) for monitoring the operational efficiency of a ship. By monitoring the EEOI, the shipowner or operator can establish strategic plans, such as routing, hull cleaning, decommissioning, new building, etc. The key parameter in calculating EEOI is Fuel Oil Consumption (FOC). It can be measured on board while a ship is operating. This means that only the shipowner or operator can calculate the EEOI of their own ships. If the EEOI can be calculated without the actual FOC, however, then the other stakeholders, such as the shipbuilding company and Class, or others who don't have the measured FOC, can check how efficiently their ships are operating compared to other ships. In this study, we propose a method to estimate the EEOI without requiring the actual FOC. The Automatic Identification System (AIS) data, ship static data, and environment data that can be publicly obtained are used to calculate the EEOI. Since the public data are of large capacity, big data technologies, specifically Hadoop and Spark, are used. We verify the proposed method using actual data, and the result shows that the proposed method can estimate EEOI from public data without actual FOC.

为了防止船舶污染，能源效率设计指数（EEDI）是所有新船的强制性指南。MARPOL还已将《船舶能源效率管理计划》（SEEMP）应用于所有现有船舶。SEEMP提供了能效运营指标（EEOI），用于监控船舶的运营效率。通过监视EEOI，船东或运营人可以制定战略计划，例如航线，船体清洁，退役，新建建筑物等。计算EEOI的关键参数是燃油消耗量（FOC）。可以在船上操作时在船上进行测量。这意味着只有船东或运营人才能计算其自己船舶的EEOI。但是，如果可以在没有实际FOC的情况下计算EEOI，则其他利益相关者（例如造船公司和Class）或其他没有FOC测量值的人，可以检查其船只与其他船只相比运行的效率如何。在这项研究中，我们提出了一种无需实际FOC即可估算EEOI的方法。可以公开获取的自动识别系统（AIS）数据，船舶静态数据和环境数据用于计算EEOI。由于公共数据具有大容量，因此使用了大数据技术，尤其是Hadoop和Spark。我们使用实际数据验证了该方法，结果表明该方法可以在没有实际FOC的情况下根据公开数据估算EEOI。可以公开获取的自动识别系统（AIS）数据，船舶静态数据和环境数据用于计算EEOI。由于公共数据具有大容量，因此使用了大数据技术，尤其是Hadoop和Spark。我们使用实际数据验证了该方法，结果表明该方法可以在没有实际FOC的情况下根据公开数据估算EEOI。可以公开获取的自动识别系统（AIS）数据，船舶静态数据和环境数据用于计算EEOI。由于公共数据具有大容量，因此使用了大数据技术，尤其是Hadoop和Spark。我们使用实际数据验证了该方法，结果表明该方法可以在没有实际FOC的情况下根据公开数据估算EEOI。
