Welcome to the website where you can pass online the CES CBT CD-8536 test on the subject «Ex Inspection and Maintenance». 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 «Ex Inspection and Maintenance». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Ex Inspection and Maintenance» 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. It involves the regular examination and upkeep of equipment and facilities to ensure they meet safety and operational standards. The primary goal of the test is to prevent equipment failures and ensure the safety of personnel and the environment. These inspections are crucial for identifying potential hazards and addressing them before they become significant issues. Regular maintenance activities include cleaning, lubricating and replacing worn-out parts to extend the lifespan of the equipment. The course procedures are often guided by regulatory requirements and industry best practices. Proper documentation of inspections and maintenance activities is essential for tracking the condition of equipment over time. Training programs are often implemented to ensure that personnel are knowledgeable about the inspection and maintenance processes. Effective test can lead to increased efficiency, reduced downtime and lower operational costs.
On this site Crew Evaluation System Test on the subject «Ex Inspection and Maintenance» contains 30 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.
