Enhancing maritime transportation security: A data-driven Bayesian network analysis of terrorist attack risks.

Maritime terrorist accidents have a significant low-frequency-high-consequence feature and, thus, require new research to address the associated inherent uncertainty and the scarce literature in the field. This article aims to develop a novel method for maritime security risk analysis. It employs real accident data from maritime terrorist attacks over the past two decades to train a data-driven Bayesian network (DDBN) model. The findings help pinpoint key contributing factors, scrutinize their interdependencies, ascertain the probability of different terrorist scenarios, and describe their impact on different manifestations of maritime terrorism. The established DDBN model undergoes a thorough verification and validation process employing various techniques, such as sensitivity, metrics, and comparative analyses. Additionally, it is tested against recent real-world cases to demonstrate its effectiveness in both retrospective and prospective risk propagation, encompassing both diagnostic and predictive capabilities. These findings provide valuable insights for the various stakeholders, including companies and government bodies, fostering comprehension of maritime terrorism and potentially fortifying preventive measures and emergency management.

Is geopolitics a threat for offshore wind energy? A case of Indian Ocean Region.

The aim of this paper is to drive the discourse towards the increasing shift to renewables, especially offshore wind energy generation, in the emerging international energy order. The Indian Ocean Region (IOR), despite its increasing contribution to onshore wind energy generation and impending policies on offshore wind energy, is reluctant to invest in the latter. Hence, this paper highlights four important aspects that challenge IOR's offshore wind energy development: Indian Ocean's strategic location, environment impacts, blue economy and maritime terrorism. In the background of the geopolitical rivalry existing in the Indian Ocean Region (IOR), with the increasing presence of China and the USA in the Indian Ocean, this paper aims to study if these geopolitical challenges are hindering offshore wind energy generation in IOR. The key findings of the paper include the necessity of addressing the geopolitical rivalry in IOR as an important hindrance in huge investments needed in OWE farms, so that a regional cooperative mechanism is arrived at especially from the point of view of policies towards OWE generation.
