Welcome to the website where you can pass online the Seafarer Evaluation Training System (SETS) test on «EO1: Use Hand and Power Tools for Fabrication and Repair». 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 «EO1: Use Hand and Power Tools for Fabrication and Repair». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«EO1: Use Hand and Power Tools for Fabrication and Repair» subject includes theoretical and practical information about advanced training for work on any type of vessel. This test assesses a candidate’s proficiency in selecting, operating and maintaining a wide array of hand and power tools common in a shipboard environment. Participants must demonstrate a thorough understanding of safety protocols, including the correct use of Personal Protective Equipment (PPE) and hazard mitigation for specific tools like angle grinders and welding equipment. A key component of the evaluation involves performing precise fabrication tasks, such as measuring, cutting and joining metal pieces to create or repair a shipboard component. Candidates will be evaluated on their ability to conduct pre-use inspections on power tools to identify potential defects, wear or safety hazards before operation. The exam includes scenarios requiring the proper selection of tools for specific maintenance jobs, such as disassembling a pump using correct wrenches and pullers or threading a pipe. Practical skills in using cutting tools (e. g., plasma cutters, oxy-acetylene torches) and shaping tools (e. g., hydraulic presses, drills) for steel repair are rigorously tested. Knowledge of post-operation procedures, including proper tool cleaning, storage and the reporting of any malfunctions, is a critical part of the assessment. Successful completion validates the advanced competency required to perform safe, effective and efficient fabrication and repair work on any type of vessel using both hand and power tools.
On this site SETS on the subject «EO1: Use Hand and Power Tools for Fabrication and Repair» contains 172 questions you need to answer with no possibility to go back to previous question.
