Welcome to the website where you can pass online the Computer Based Test (CBT) also known as Crew Evaluation System (CES) on the subject «High Voltage, Fundamentals». 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.
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 «High Voltage, Fundamentals». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«High Voltage, Fundamentals» 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. The main parameters of the ship’s electrical power system are the type of current, voltage and frequency. Together with other parameters, they determine the reliability, weight, dimensions, cost and performance of the electrical equipment of the ship’s electrical power system. The rated voltage accepted for ship electric power systems depends on the installed power of the ship power plant and the distances over which it is necessary to transmit electricity to ship consumers. The use of the highest possible voltage gives a tangible gain in the mass and cost of the ship’s cable network. Therefore, on large ships, where there are long lines with powerful consumers at the end, the maximum possible voltage is usually chosen, equal to 380 V for alternating current and 220 V for direct current.
However, it should be borne in mind that an increase in voltage is associated with an increase in the likelihood of electric shock to people.
On this site Crew Evaluation System Test on the subject «High Voltage, Fundamentals» contains 45 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.
