Logistics Service Centers as Drivers of Innovation and Competitiveness in Nautical Tourism Ports – Case Study of ACI Marina Šimuni

This study investigates the integration of a Logistics Service Center (LSC) within ACI Marina Šimuni as a model for enhancing economic performance, operational efficiency, and environmental sustainability in nautical tourism ports. Specifically, the research provides an in-depth examination of how LSC implementation addresses service gaps, mitigates ecological impacts, and aligns effectively with Croatia’s strategic objectives for sustainable tourism development. The research combines qualitative and quantitative methodologies. Data collection involves a detailed analysis of marina infrastructure, operational capacity, and environmental effects, complemented by projections of revenues and costs. Financial viability is assessed using the payback period, net present value (NPV), and internal rate of return (IRR) methods. Environmental assessments focus on antifouling systems and wastewater management. The LSC requires an investment of 1.17 million EUR over two years, with cumulative net cash flow turning positive in 2031 and reaching 642,388.11 EUR by 2035. Service revenues are projected to grow from 360,000 EUR in 2026 to 430,233 EUR in 2035. Positive NPV and an IRR of 9.94% confirm long-term profitability. From an environmental perspective, advanced cleaning systems and eco-friendly antifouling technologies reduce copper leaching and biofouling, while facility enhancements, such as a modular hangar and travel lift, improve service quality and operational efficiency. The integration of the LSC at ACI Marina Šimuni demonstrates transformative potential in balancing economic growth with environmental stewardship. The project’s financial viability, supported by positive NPV and IRR values, underscores its attractiveness to investors. On an environmental level, the adoption of advanced waste management practices and antifouling technologies aligns closely with EU sustainability standards, thereby safeguarding marine ecosystems. Strategically, the LSC enhances the marina’s competitiveness, providing opportunity to position it as a leader in sustainable nautical tourism. The proposed integration model offers practical insights that can be scaled to other nautical ports, thus reinforcing Croatia’s broader strategy for sustainable maritime development.
