Abstract: The growing cruise industry, marked by the increasing vessel sizes and exacerbated by the palpable impacts of climate change, is precipitating an imperative reevaluation of global port facilities. The phenomenon of rising sea levels, coupled with the unpredictability of weather patterns, underscores the inadequacies of many extant ports, which were conceived and constructed under now-obsolete standards. These facilities, facing the dual challenges of structural obsolescence and evolving industry demands, are at a crossroads: they must undergo either substantial upgrades or a comprehensive redesign to remain viable. In light of these pressing concerns, our study endeavors to chart a forward path, proposing an integrated methodology aimed at enhancing the layout of ports designated for cruise ship docking. This approach is centered on bolstering structural resilience and adaptability, thereby ensuring these critical infrastructures can accommodate the dynamic requirements of the modern cruise market.
The cornerstone of our research is a meticulous analysis aimed at optimizing the spatial arrangement of berths and the strategic placement of bollards within a specified locale. This investigation is driven by three principal objectives: the minimization of primary vessel movement, the reduction of forces exerted on bollards, and the alleviation of loads borne by mooring lines. To achieve these ends, our study meticulously examines the interaction of cruise ships, encompassing two distinct size categories, under static mooring conditions. This analysis is predicated on a comprehensive consideration of various factors, including the physical attributes of the vessels, the forces generated by wind and currents, and the unique environmental characteristics of the site, such as prevailing wind directions and current velocities.
Employing a multi-objective optimization framework, our research leverages surrogate-based modeling techniques to discern the most efficacious berth configurations. This surrogate model is instrumental in pinpointing the optimal locations for bollard placement and determining the most favorable orientations for the berths, all while taking into account the environmental parameters specific to the site. This avant-garde methodology is not only congruent with the contemporary exigencies of the cruise industry but also rigorously adheres to the stringent standards delineated by authoritative bodies such as the UFC (Unified Facilities Criteria) and the ASCE (American Society of Civil Engineers).
In addition to addressing the immediate practical concerns of port configuration and vessel accommodation, our study is animated by a broader vision. It seeks to contribute to the sustainable evolution of maritime infrastructure by incorporating resilience and flexibility into the design and layout of cruise ports. This perspective acknowledges the inevitable progression of the cruise industry toward larger ships and the concomitant need for ports that can efficiently manage increased passenger volumes and enhanced operational demands. Moreover, by integrating considerations of climate change and environmental sustainability into the optimization process, our research underscores the importance of forward-looking strategies in the development of maritime infrastructure.
