Join Our Telegram (Seaman Community)

Welcome to the website where you can pass online the CES CBT CD-8539 test on the subject «Exi Verification and Documentation». 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 Verification and Documentation». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.

«Exi Verification and Documentation» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test is designed to provide training for personnel working on ships of various types. The course provides comprehensive training for maritime professionals seeking to enhance their qualifications for working on different types of vessels. This advanced training program covers essential documentation procedures and verification protocols required for safe vessel operation. Sailors learn about international maritime regulations and standards that govern various types of ships and their documentation requirements. The course includes knowledge and exercises to ensure proper understanding of verification processes aboard different vessels. Participants study the specific documentation requirements for cargo ships, passenger vessels, tankers and other specialized marine transport. The training program emphasizes the importance of proper record-keeping and verification procedures in maintaining maritime safety standards. Participants gain expertise in handling emergency documentation and verification procedures across different types of marine vessels. The test prepares maritime professionals to effectively manage and verify essential documentation regardless of the vessel type they work on.

On this site Crew Evaluation System Test on the subject «Exi Verification and Documentation» contains 32 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.
