Welcome to the website where you can pass online the CES test on the subject «Engine Ratings». 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.
- Version: 6.0.
- Test type: STCW.
- Department: Engine.
- Type: Ratings.
CES tests have proven themselves as good tools for the selection and recruitment process, as well as advancing the level of knowledge of the current officers and crew. Ocean Technologies Group use various subjects for question creation, which includes:
- Crowd and Crisis Management;
- Integrated Navigation System (INS);
- Ballast water management;
- Handling and Stowage;
- Vessel operation management and safety;
- Marine engineering;
- Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Engine Ratings». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Engine Ratings» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test evaluates both knowledge and skills required for working with marine engines on various types of vessels. It includes multiple-choice questions on engine components, maintenance procedures and troubleshooting techniques. Practical assessment tasks may involve diagnosing engine malfunctions or performing routine inspections. Candidates are tested on their understanding of fuel systems, cooling mechanisms and lubrication in marine engines. Safety protocols, such as handling hazardous materials and emergency shutdown procedures, are a key part of the exam. The test also covers regulatory compliance, including international maritime engine standards and environmental regulations. Advanced sections assess the ability to optimize engine performance under different operating conditions. This qualification confirms that a marine engineer is competent to operate and maintain engines on commercial or industrial vessels.
On this site Crew Evaluation System Test on the subject «Engine Ratings» contains 72 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.
