An ocean engineer is a professional who designs and develops structures and systems that operate in or near oceans and other large bodies of water. Their work often involves creating solutions for challenges like underwater construction, marine transportation, and environmental protection. They may design structures such as offshore oil rigs, submarine cables, and coastal defenses. Ocean engineers use principles from various fields, including civil engineering, mechanical engineering, and environmental science. They often collaborate with scientists and other engineers to ensure that their projects are safe, efficient, and sustainable. Their work is crucial for industries like fishing, shipping, and renewable energy.
