Vessel maintenance activities must comply with various international and national regulations, classification society rules, and industry standards. Regular inspections and surveys by classification societies and flag state authorities ensure that vessels meet regulatory requirements for safety, environmental protection, and operational integrity. Periodic dry docking of vessels is necessary for more extensive inspections, maintenance, and repairs that cannot be performed while the vessel is afloat. Special surveys conducted during dry docking assess the structural integrity and overall condition of the vessel, ensuring compliance with regulatory standards and identifying necessary repairs or upgrades. Comprehensive records of maintenance activities, inspection reports, repair history, and compliance documentation are maintained to demonstrate regulatory compliance, track equipment performance, and inform future maintenance planning.
