Naval engineering is a branch of engineering that focuses on the design, construction, maintenance, and operation of ships, submarines, and other maritime structures. It encompasses a wide range of disciplines such as hydrodynamics, structural engineering, marine propulsion, and naval architecture. Naval engineers work to design and improve vessels in terms of performance, efficiency, safety, and sustainability. They may also be involved in developing new technologies for marine propulsion systems, navigation systems, and other shipboard systems. Naval engineering plays a crucial role in the maritime industry, military defense, and offshore oil and gas exploration.
