Seaports are critical to the global supply chain, and as maritime trade grows with globalization, inefficiencies in port call processes and ship waiting times are increasing. This research develops a framework for Port Call Optimization (PCO) models to support collaboration and decision-making between stakeholders within the Nautical Chain (NC) and terminals. The Design Science Research (DSR) approach provides a systematic way to design a PCO tool for a port that is backed by a strong knowledge base. Integrating this approach with the co-design process involving user input ensures that the tool aligns with client needs and trends. This study uncovers a framework to assess the prerequisites for PCO tool implementation and develops steps to build a roadmap for PCO tools that incorporate the intricacies of different port governance structures. The findings from this research lays the groundwork for future research regarding the implementation of a PCO tool by bridging the gap between the fragmented research in this domain.

Collaborative Port Call Optimization (PCO) is a key strategy to improve port efficiency. This study aims to bridge existing research gaps by providing a holistic understanding of collaborative PCO adoption, emphasizing the complexities of multi-organization collaboration and the influence of emerging technologies within the nautical chain and Port Governance structures. The TOEI framework, a novel conceptual model that extends the Technological Organizational-Environmental (TOE) framework, offers a valuable tool for port authorities and operators, providing specific insights and recommendations to enhance port call processes collaboratively. The study targets not only academics but also policymakers, port authorities, and nautical service providers. The findings discovered through the empirical analysis and the development of the TOE framework provide valuable insights for ports seeking to enhance their port calls collaboratively, laying the groundwork for future research, encouraging further exploration of specific contextual factors, in-depth case studies, and the development of tailored strategies for diverse ports globally.

Carbon Capture and Storage (CCS) is considered an essential solution to reaching climate goals. The two main identified transport modes in CCS, pipelines and ships, are widely compared to each other in the literature. This research contributes to the literature about the evaluation of transportation modes in CCS chains, by determining to what extent electrified ships can play a role in CCS. This is not studied before. This research is executed by following the Systems Engineering approach, in particular the SIMIE process. In a proposed point-to-point network for onshore transportation, mainly general diesel-propelled barges would perform with the lowest costs per ton, whereby the distance ranges from 25 km up to 250 km. As longer the distances, more Tank-to-Wheel (TTW) emissions savings could be obtained if barge transport is electrified. Identifying the most accurate emissions reporting method and performing operational validation for modelling the transport modes and trajectories could provide the obtained results with more scientific and practical robustness.
