Ocean Engineering is a multidisciplinary engineering field aimed at solving engineering problems associated with working in the ocean environment and wisely exploring and harnessing the ocean’s resources.
Ocean engineers design, build, operate and maintain ships, offshore structures and ocean technologies as diverse as aircraft carriers, submarines, sailboats, tankers, tugboats, yachts, oil rigs, underwater robots, and acoustic sonar.
Ocean engineers study the oceans to determine the effects of waves, currents, and the salt water environment on ships and other marine vehicles and structures.
They develop methods and materials to withstand wave forces and protect against corrosion. Ocean engineers are involved in development and use of manned and remotely operated sub-surface vehicles for deep-sea exploration and resource recovery.
