Welcome to the website where you can pass online the CES CBT CD-0303, 0304 test on the subject «COLREG – lights, shapes and sound signals, conduct of vessels». 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 «COLREG – lights, shapes and sound signals, conduct of vessels». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«COLREG – lights, shapes and sound signals, conduct of vessels» subject includes theoretical and practical information about advanced training for work on any type of vessel. This comprehensive program delves into the International Regulations for Preventing Collisions at Sea (COLREGs), equipping participants with a thorough understanding of navigational rules and responsibilities. Participants will learn to identify and interpret various vessel lights, shapes and sound signals, enabling them to assess the situation and make informed decisions in accordance with COLREGs. The training covers maneuvering and conduct guidelines for different vessel types and encounter situations, including overtaking, crossing and head-on scenarios. Practical exercises will allow trainees to apply their knowledge in realistic scenarios, enhancing their ability to navigate safely and prevent collisions. This advanced training is essential for deck officers, watchkeepers and other maritime professionals responsible for safe navigation and compliance with international regulations.
On this site Crew Evaluation System Test on the subject «COLREG – lights, shapes and sound signals, conduct of vessels» contains 77 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.
