Welcome to the website where you can pass online the Computer Based Test (CBT) also known as Crew Evaluation System (CES) on the subject «Electric Propulsion, Power Electronics». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CES/CBT based on practical information and marine specialists experience.
CES & CBT 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.

- Integrated Navigation System (INS);
- Ballast water management;
- Handling and Stowage;
- Vessel operation management and safety;

- Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Electric Propulsion, Power Electronics». These questions can be used to test the competence of a person capable of performing their duties in working with electric motors on a ship, as well as for self-testing.
«Electric Propulsion, Power Electronics» subject includes theoretical and practical information about advanced training for work on the ship. Knowledge of this information directly indicates the competence of the employee holding the relevant position on the ship. Many modern ships are equipped with electric propulsion systems. The general trend is the use of AC electric propulsion systems, which is due to the more reliable design of the asynchronous motor and somewhat better weight and size indicators.
The combination of an internal combustion engine and an electric motor has numerous advantages and is particularly attractive for shipping. For example, in addition to a significant reduction in fuel consumption (up to 28 %!), noise and vibration levels are also significantly reduced.
