Current test contains Seagull CBT questions on the subject «Oil Tanker Training System». Those questions can be used for competence verification specialist capable of preventing accidental situations related with transporting safety, or also for self-examination.
«Oil Tanker Training System» subject includes theoretical and practical information about advanced training for work on any type of vessel. The test evaluates both knowledge and skills for safe operations on crude and product tankers, in compliance with international regulations. It includes multiple-choice questions on cargo properties, tanker design features and specialized systems like inert gas generators and vapor recovery units. Candidates must demonstrate their understanding of guidelines for oil tanker operations. Scenario-based questions assess decision-making during critical operations, including cargo transfers, tank cleaning and emergency shutdown procedures. Practical components test proficiency in spill response protocols, gas detection equipment use and enclosed space entry procedures specific to tanker environments. The exam covers hazard mitigation strategies for static electricity, oxygen deficiency and hydrocarbon exposure risks during routine operations. Questions on pollution prevention measures evaluate knowledge of slop management, ballast water treatment and discharge control systems. Successful completion certifies competence in advanced tanker operations, ensuring compliance with STCW requirements and enhancing safety in the petroleum shipping sector.
