The «Deck Operational Oil Tanker» subject provides both theoretical and practical knowledge on safely working with electrical equipment. Mastery of this information is a key indicator of an employee's competence in a relevant position on a vessel. As the 3rd officer on an oil tanker, your primary responsibilities would include assisting senior officers in the safe navigation and operation of the ship. You would be tasked with maintaining accurate navigational records, performing regular safety inspections, and ensuring compliance with all relevant maritime regulations. Additionally, you would supervise the deck crew, oversee cargo operations, and conduct regular safety drills and training exercises. As a junior officer, you would be expected to learn from and support the more experienced crew members while gaining valuable experience for future roles in the maritime industry.
