Join Our Telegram (Seaman Community)

Welcome to the website where you can pass online the CES CBT CD-8537 test on the subject «Exi Protection Concepts (Exi a, b, c, nl)». 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.

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 «Exi Protection Concepts (Exi a, b, c, nl)». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.

«Exi Protection Concepts (Exi a, b, c, nl)» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test is designed to provide advanced training for personnel working on ships of various types. Exi Protection Concepts (Exi a, b, c, nl) cover advanced training for personnel working on various types of vessels, ensuring they are well-prepared for any operational challenges. The training program includes components, providing a comprehensive understanding of safety and operational procedures. Exi a focuses on the fundamentals of explosion protection, including the identification and mitigation of hazardous areas on vessels. Exi b delves into the specific requirements and standards for electrical equipment in hazardous environments, ensuring compliance with international regulations. Exi c addresses the practical aspects of maintenance and inspection, teaching personnel how to handle and maintain equipment safely. Exi nl emphasizes the importance of non-electrical equipment and its role in maintaining a safe working environment on vessels. The test is designed to assess the knowledge and skills of personnel, ensuring they are competent in applying Exi Protection Concepts in real-world scenarios. Successful completion of this test training and test equips personnel with the advanced skills needed to work safely and efficiently on any type of vessel.
