Sustainable Seaport Development and Strategic Modernisation of Maritime Transport Infrastructure

Background. Effective strategic management of maritime transport infrastructure development is impossible without creating conditions for sustainable development. The main risks to Ukraine’s strategic management of maritime transport infrastructure development under martial law were examined, and prospects for its development were based on sustainable development principles. Purpose. This study aims to examine strategic management in the maritime transport infrastructure of Ukraine, focusing on an indicative sustainability framework for ports and identifying the primary components of a performance-management system for sustainable development. Findings. This study analysed the key factors influencing the competitiveness of Ukraine’s maritime transport infrastructure and forecast potential developments for 2026–2030. Security factors account for 44.0% of strategic management issues, and environmental factors account for 9.0%, resulting in a low connectivity index for Ukraine’s liner shipping industry (12.6% lower than the EU average). The analysis validated an indicative-integrated assessment model that includes two complementary systems: port sustainability indicators and management key performance indicators. The estimated Integrated Sustainability Index of the Port System for 2024 is 0.816 (high level), indicating adaptive stabilisation under martial law. The Sustainable Development Management Performance Index for the port system in 2024 is 0.768 (moderately high), confirming consistent policy implementation and adaptive capacity. The key performance indicators include an 8.5% increase in cargo turnover, a 6.0% increase in revenue, a 17.8% share of green investments, and a digital maturity level of 0.68, indicating operational stability and the potential for further sustainable development. Implications. The current risks in the strategic management of Ukraine’s maritime transport infrastructure development are predominantly security-related. However, risks require continuous monitoring of sustainable development and the effectiveness of its management, considering the potential negative impact of maritime transport infrastructure on environmental safety. A vision of the strategic development mechanism for maritime transport infrastructure in the context of sustainable development was formulated, and a quantitative assessment mechanism for the sustainable development process and its management effectiveness was defined.
