The current test includes Seagull CES questions on the topic of «Engine, Operational, Medium Speed». These questions are designed to verify the competence of specialists who are responsible for preventing accidents related to transport safety and can also be used for self-assessment.
The «Medium Speed» subject provides both theoretical and practical knowledge essential for advanced training on any type of vessel. Mastery of this information is a clear indicator of an employee’s competence in their role on board. A professional responsible for maintaining a medium-speed engine on a vessel has a range of crucial duties to ensure the ship’s safety and efficiency. This includes conducting regular technical maintenance, such as inspections, cleaning, replacing components, and lubricating bearings. Additionally, they monitor and adjust operational parameters like temperature, pressure, and fuel consumption to meet established standards, thereby ensuring optimal engine performance.
- Test type: STCW.
- Version: 5.2.7, 6.0.
