#1 Regulatory Compliance and Safety Standards

When it comes to flag states, regulatory compliance and safety standards are paramount. Each flag state enforces a unique blend of international regulations, including SOLAS, MARPOL, and ISM, which directly affect the ship’s operational requirements. A flag state’s reputation for compliance also influences how often its vessels are inspected and detained, impacting overall operational efficiency.
