The «Deck Support Level Oil Tanker» subject provides both theoretical and practical knowledge on safely working with electrical equipment. Understanding this information is a key indicator of an employee's competence in their role aboard a vessel. Deck support on an oil tanker primarily involves assisting the ship’s officers with tasks related to the maintenance and operation of the deck and cargo systems. Responsibilities may include overseeing the safe loading and unloading of cargo, monitoring weather conditions, maintaining navigational equipment, conducting safety drills, and regularly inspecting the ship’s structural integrity.
As an officer, it's also essential to be ready to take command in emergency situations and collaborate closely with other crew members to ensure the safety of the vessel and everyone on board.
