Marine four-stroke engines│Marine training course

Four-stroke engines form the backbone of auxiliary power generation and medium-speed propulsion across the global fleet. As shipping transitions toward greener fuels and smarter systems, understanding their operation within dual-fuel, hybrid and energy-efficient configurations is increasingly vital.

This 2-day course provides a practical and structured overview of four-stroke marine engines, focusing on performance monitoring, maintenance planning, and integration into evolving vessel power plant technologies.

Participants will develop an in-depth understanding of the configuration, operation and performance of four-stroke marine engines. They will be able to identify faults, plan maintenance activities, handle dual-fuel and hybrid systems, coordinate with class, OEM and shipboard personnel to ensure reliable and compliant operation of modern power-generation systems.

Introduction to four-stroke marine engines: purpose and application areas
Construction and operating principles of medium-speed four-stroke engines
Cylinder head, valve train, fuel-injection systems and crankshaft
Dual-fuel operation and alternative fuels (LNG, methanol, ammonia readiness)
Common Rail injection system
Turbocharging, air/fuel ratio control and exhaust systems
Integration of four-stroke units in hybrid and electric power plant configurations
Performance analysis and trending for four-stroke engines
Failure mechanisms and diagnostic techniques (cylinder condition, valve wear, combustion monitoring, turbo failures)
Maintenance and overhaul planning: major works, spare logistics, coordination with workshops
Class and statutory requirements for auxiliary engines and generators
Emission compliance (SCR-ΝΟR Systems)
Energy efficiency and load management strategies
Troubleshooting and case-study discussions from real fleet examples

This course is designed for marine engineers, technical superintendents, fleet engineers, ship repair supervisors and senior shipboard engineers who are responsible for four-stroke engines or auxiliary power plants. It also benefits professionals involved in performance monitoring, hybrid system integration or alternative-fuel operations.
