The «Deck Management Bulk Carrier» subject provides both theoretical and practical knowledge on safely working with electrical equipment. Mastery of this material is a clear indicator of an employee’s competence in their role aboard a vessel. A bulk carrier is a specialized type of ship designed to transport large quantities of loose bulk cargo, such as coal, grain, ore, or cement. These ships are distinguished by their large size, with a high freeboard (the vertical distance from the waterline to the deck) and a broad, flat deck. Bulk carriers come in various types, categorized by size, cargo capacity, and hull design, including Handysize, Supramax, Panamax, Capesize, and Valemax. They play a critical role in the global shipping industry, transporting raw materials and commodities between ports.
