Welcome to the website where you can pass online the Computer Based Test (CBT) also known as Crew Evaluation System (CES) on the subject «Flex Inert Gas Generator System». 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 «Flex Inert Gas Generator System». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Flex Inert Gas Generator System» subject includes theoretical and practical information about inert gas generator. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel, provides to understand purposes of an inert gas generator, how inert gases on a ship used, be able to maintain, and to work with.
On this site Crew Evaluation System Test on the subject «Flex Inert Gas Generator System» contains 16 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.
