	abstract = {The paper argues for the necessity of a combination MMR methods (questionnaire, interview) and sentiment/opinion techniques to personal satisfaction analysis at the maritime and training education and proposes a generic, but practical research approach for this purpose. The proposed approach concerns the personal satisfaction evaluation of Engine Room simulator systems and combines the speech recording (sentiment/opinion analysis) for measuring emotional user responses with usability testing (SUS tool). The experimental procedure presented here is a primary effort to research the emotion analysis (satisfaction) of the users-students in Engine Room Simulators. Finally, the ultimate goal of this research is to find and test the critical factors that influence the educational practice and user?s satisfaction of Engine Room Simulator Systems and the ability to conduct full-time system control by the marine crew.},
