Welcome to the website where you can pass online the CES test on the subject «Engine, Operational, Medium Speed». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CES based on practical information and marine specialists experience.
CES tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.
- Test type: STCW.

Current test contains Seagull CES questions on the subject «Engine, Operational, Medium Speed». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Medium Speed» subject includes theoretical and practical information about advanced training for work on any type of vessel. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel. An individual responsible for servicing a medium-speed engine on a vessel shoulders a range of critical responsibilities to ensure the safety and efficiency of the ship. This professional conducts regular technical maintenance of the engine, encompassing inspections, cleaning, and replacement of components, as well as the lubrication of bearings. Monitoring and adjusting operational parameters such as temperature, pressure, and fuel consumption to comply with established standards is also part of the job, ensuring optimal engine performance.
On this site Crew Evaluation System Test on the subject «Engine, Operational, Medium Speed» contains 120 questions you need to answer with no possibility to go back to previous question. Therefore, we recommend carefully reading each question and making decision with no hurry. In case you have some difficulty answering, you have also possibility to request a hint.
The test includes three modes. In the Training mode, you go through 60 questions with the option to take a hint, while in the Exam mode, this option is not available. We have also developed another mode – Wild, where you can answer all the questions available in the test at once. Enjoy!
