Join Our Telegram (Seaman Community)

Welcome to the website where you can pass online the CBT test on the subject «Marine Fuel Properties (CD Module 0011)». Practice like this will help you as a marine specialist improve your knowledge with the help of online studying and appraisal practice. CBT based on practical information and marine specialists experience.

CBT tests developed for evaluating seaman basic knowledge by Seagull Company (rebranded as «OTG»), is an evaluating online-tool, used for revealing any professional preparation needed in specific fields of knowledge, defined by STCW.

CBT 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. Ocean Technologies Group use various subjects for question creation, which includes:

  • Crowd and Crisis Management;
  • Integrated Navigation System (INS);
  • Ballast water management;
  • Handling and Stowage;
  • Vessel operation management and safety;
  • Marine engineering;
  • Maintenance and repair, etc.

Current test contains Seagull CBT questions on the subject «Marine Fuel Properties (CD Module 0011)». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.

«Marine Fuel Properties (CD Module 0011)» subject includes theoretical and practical information about advanced training for work on any type of vessel. This test covers essential aspects of fuel characteristics, including viscosity, density and sulfur content, crucial for vessel operation. The course provides in-depth knowledge of fuel combustion processes and their impact on engine performance and emissions. Participants learn to analyze fuel quality, detect contaminants and apply corrective measures to ensure safe and efficient vessel operation. Advanced training includes studying alternative marine fuels like LNG, biofuels and hydrogen to meet environmental regulations. Proper fuel handling, storage and treatment techniques are emphasized to prevent machinery damage and operational failures. The course aligns with IMO standards, including MARPOL Annex VI, to ensure compliance with global emission regulations. Practical simulations and case studies help trainees understand real-world challenges in fuel management on different vessel types. Upon completion, seafarers gain the expertise to optimize fuel consumption, reduce costs and minimize environmental impact.

On this site Crew Evaluation System Test on the subject «Marine Fuel Properties (CD Module 0011)» contains 7 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. Enjoy!
