Architecture and Engineering

Marine engineers and naval architects design, build, and maintain ships, from aircraft carriers to submarines and from sailboats to tankers. Marine engineers are also known as marine design engineers or marine mechanical engineers and are responsible for the internal systems of a ship, such as the propulsion, electrical, refrigeration, and steering systems. Naval architects are responsible for the ship design, including the form, structure, and stability of hulls.

Materials engineers develop, process, and test materials used to create a range of products, from computer chips and aircraft wings to golf clubs and biomedical devices. They study the properties and structures of metals, ceramics, plastics, composites, nanomaterials (extremely small substances), and other substances in order to create new materials that meet certain mechanical, electrical, and chemical requirements. They also help select materials for specific products and develop new ways to use existing materials.

Mechanical engineers research, design, develop, build, and test mechanical and thermal sensors and devices, including tools, engines, and machines.

Mechanical engineering technologists and technicians help mechanical engineers design, develop, test, and manufacture tools, engines, machines, and other devices. They may make sketches and rough layouts, record and analyze data, and report their findings.

Mining and geological engineers design mines to safely and efficiently remove minerals such as coal and metals for use in manufacturing and utilities.

Nuclear engineers research and develop projects or address problems concerning the release, control, and use of nuclear energy and nuclear waste disposal. Some of these engineers research new reactor designs. Others may specialize in the development of safety regulations related to the handling of nuclear materials or operation of nuclear power.

Petroleum engineers design and develop methods for extracting oil and gas from deposits below the Earth’s surface. Petroleum engineers also find new ways to extract oil and gas from older wells.

Surveying and mapping technicians collect data and make maps of the Earth’s surface. Surveying technicians visit sites to take measurements of the land. Mapping technicians use geographic data to create maps. They both assist surveyors, and cartographers and photogrammetrists.

Surveyors make precise measurements to determine property boundaries. They provide data relevant to the shape and contour of the Earth’s surface for engineering, mapmaking, and construction projects.
