- Marine engineering;
- Maintenance and repair, etc.
Current test contains Seagull CES questions on the subject «Engine, Support level». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Engine, Support level» subject includes theoretical and practical information about advanced training for work on any type of vessel. Knowledge of this information directly shows employee’s competence who holds a relevant post on a vessel. On board a vessel, the technical maintenance of the engine is typically managed by a team of dedicated marine engineers or engine crew members. These professionals are responsible for ensuring the engine’s proper functioning, conducting routine inspections, and performing necessary repairs or adjustments. Maintaining an optimal engine support level is crucial for safe and efficient maritime operations, as it helps prevent breakdowns at sea and ensures compliance with industry regulations, ultimately safeguarding both the vessel and its crew.
On this site Crew Evaluation System Test on the subject «Engine, Support level» contains 86 questions you need to answer with no possibility to go back to previous question.
