Legal and Practical Aspects of MARPOL Port State Control Inspections

This research investigates the legal and practical dimensions of Port State Control (PSC) inspections as mandated by the International Convention for the Prevention of Pollution from Ships (MARPOL). Utilizing a qualitative methodology, the study integrates comprehensive document analysis, semi-structured interviews with maritime stakeholders, and illustrative case studies to evaluate the efficacy of PSC inspections in ensuring regulatory compliance and environmental protection. The findings indicate a relatively stable compliance rate of 94.1% to 95.7% over a five-year period, with recurring deficiencies primarily identified in Oil Record Book discrepancies and sewage treatment systems. Significant regional variations were observed, wherein European ports demonstrated stricter enforcement mechanisms compared to those in other regions, highlighting disparities in global implementation practices. Challenges such as resource constraints, inconsistent inspector training, and limited collaboration between port states and flag states were identified as critical barriers to effective enforcement. The study emphasizes the necessity of targeted training programs, enhanced inter-regional cooperation, and the integration of advanced technologies to improve inspection processes and foster a uniform enforcement regime. These findings contribute to the discourse on maritime governance by offering evidence-based recommendations for policymakers and regulatory bodies aimed at strengthening the effectiveness of PSC inspections and advancing marine environmental protection.
