Welcome to the website where you can pass online the Seafarer Evaluation Training System (SETS) test on «Rule of the Road and Buoyage». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. SETS based on practical information and marine specialists experience.
SETS tests developed for evaluating seaman basic knowledge by company “Naval Education Services” is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW Section A-V/1-2.
SETS 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.
Current test contains SETS questions in area «Rule of the Road and Buoyage». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Rule of the Road and Buoyage» subject includes theoretical and practical information about advanced training for work on any type of vessel. This subject covers the International Regulations for Preventing Collisions at Sea (COLREGs) that govern vessel navigation worldwide. Participants learn to interpret and apply navigation rules in various scenarios including overtaking, head-on and crossing situations. The course includes detailed study of the IALA buoyage systems (A and B) used in different regions of the world. Trainees practice identifying and understanding all types of navigational marks including lateral, cardinal, isolated danger and special marks. The curriculum emphasizes proper light recognition for vessels at night and during restricted visibility. Practical exercises include using buoyage systems for safe passage planning and hazard avoidance. Sailors learn sound signal protocols for communication and collision avoidance in poor visibility. The subject prepares mariners for real-world challenges in both open water and congested harbor conditions.
On this site SETS on the subject «Rule of the Road and Buoyage» contains 156 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.
