Welcome to the website where you can pass online the Seafarer Evaluation Training System (SETS) test on «GMDSS». 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 «GMDSS». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«GMDSS» subject includes theoretical and practical information about advanced training for work on any type of vessel. The GMDSS (Global Maritime Distress and Safety System) test encompasses comprehensive training for maritime communication. It covers both theoretical and practical aspects of operating advanced communication equipment on various types of vessels. The course is designed to equip individuals with the necessary skills to handle distress and safety communications effectively. GMDSS training includes understanding the different components of the system, such as satellite and terrestrial communication methods. Participants learn about the various equipment used in GMDSS. The training also emphasizes the importance of proper communication protocols and procedures in emergency situations. By mastering GMDSS, individuals can ensure compliance with international maritime regulations and enhance safety at sea. Upon completion, trainees are prepared to operate GMDSS equipment efficiently, facilitating reliable and timely communication during emergencies.
On this site SETS on the subject «GMDSS» contains 26 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.
