Abstract

Abstract Since the implementation of Emission Control Areas (ECA) in 2015, investment decisions related to abatement technologies represent a crucial task in the maritime industry. Currently, the focus in the maritime sector is on Sulphur reductions due to SECA regulations and the legislative of Global Sulphur Cap that started in 2020. A special challenge appears in maritime fleet management where sets of ships have to be considered, representing portfolios of assets that have to be equipped with a variety of different options of abatement technologies. Modern portfolio theory has been applied to various economic decisions to achieve an optimal allocation of resources among different investment opportunities. The research investigates and discusses the application of the Markowitz´ optimization in the context of SECA regulations for maritime fleets. The optimal investment portfolios are taking into account the three most important compliance options based on the use of low Sulphur fuel, the use of LNG fuel and the use of HFO with a scrubber. The theoretical results are empirically validated by a case of a shipping line operating 10 vessels.

2020年全球限硫令背景下的可持续海运船队管理

自2015年实施排放控制区(ECA)以来，与减排技术相关的投资决策是海运业的一项关键任务。目前，由于SECA法规和2020年开始的全球硫排放上限立法，海事部门的重点是硫减排。在海事船队管理中出现了一个特殊的挑战，必须考虑到船舶组，代表资产组合，必须配备各种不同的减排技术选择。现代投资组合理论已被应用于各种经济决策中，以实现资源在不同投资机会中的最优配置。本研究调查并讨论了马科维茨优化在海上船队SECA法规背景下的应用。最佳投资组合考虑了三种最重要的合规选择，即使用低硫燃料、使用液化天然气燃料和使用带洗涤器的重油。以某航运公司10艘船舶为例，对理论结果进行了实证验证。
