Welcome to the website where you can pass online the Seafarer Evaluation Training System (SETS) test on «Meteorology». 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 «Meteorology». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Meteorology» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test evaluates knowledge and skills related to the design, building and maintenance of various types of vessels. It covers essential topics such as ship structural components, materials used in construction and the principles of hull design for stability and strength. Candidates will be assessed on their understanding of construction standards, safety regulations and compliance with international maritime guidelines. The test includes practical tasks that simulate real-world scenarios, such as identifying structural defects, interpreting blueprints and planning repair procedures. Theoretical questions will focus on advanced concepts like load distribution, corrosion prevention and the integration of modern technologies in vessel construction. Successful completion of the test demonstrates the ability to contribute to the construction, inspection, or refitting of any type of vessel, from small yachts to large commercial ships. This assessment is designed to ensure that maritime professionals are equipped to uphold the highest standards of quality and safety in shipbuilding and maintenance.
On this site SETS on the subject «Meteorology» contains 100 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.
