The classification survey of ship machinery is a critical process aimed at verifying the operational safety, reliability, and compliance of key mechanical systems, including propulsion engines, generators, pumps, and auxiliary equipment.

Conducted in line with the International Register of Shipping (INTLREG) Rules and Regulations, these surveys evaluate mechanical integrity, performance under load, maintenance records, and adherence to applicable standards. Surveys are performed during new construction, periodically throughout the vessel’s life, and following any significant repairs or modifications.

INTLREG ensures each machinery component meets the required safety and performance thresholds while minimizing downtime and operational disruption. Through a balance of technical precision and service responsiveness, INTLREG supports shipowners in maintaining consistent performance and regulatory compliance, helping vessels operate efficiently across global waters under increasing industry demands.
