Agricultural engineers are also concerned with the processing, transporting, and storing of agricultural products. Computer engineering involves the development and improvement of computers, storage and printout units, and computer information networks. Computer engineers design the features of computer systems to suit particular operations. Marine engineering concerns the design, construction, and repair of ships and submarines. Marine engineers also work to develop port facilities.
Ocean engineering involves the design and installation of all types of equipment used in the ocean.
The products of ocean engineers include oil rigs and other offshore installations, marine research equipment, and breakwater systems used to prevent beach erosion. Petroleum engineering deals with producing, storing, and transporting petroleum and natural gas. Petroleum engineers locate oil and gas deposits and try to develop more efficient drilling and recovery methods. Textile engineering is concerned with the machinery and processes used to produce both natural and synthetic fibers and fabrics. Engineers in this field also work to develop new and improved textiles.
