The current test includes Seagull CES questions on the topic of «Deck, Management, Oil Tanker». These questions are designed to assess the competence of specialists in preventing accidents related to transport safety and can also be used for self-assessment.
The «Management» subject provides both theoretical and practical knowledge essential for advanced training on any type of vessel. Proficiency in this area is a direct indicator of an employee's competence in their specific role on a vessel. On an oil tanker, the Deck Management Officer is responsible for a wide range of duties that ensure the vessel's safe operation and compliance with international standards, including command, navigation, and cargo management. The specific responsibilities for deck management on an oil tanker can vary depending on company policies, as well as international regulations and standards governing maritime safety and operations at sea.
