Subsea construction involves the installation and maintenance of structures and systems located underwater, primarily in oceans and large bodies of water. This field is crucial for the development of offshore oil and gas facilities, underwater pipelines, and renewable energy projects like offshore wind farms. Specialized equipment and techniques are used to ensure safety and efficiency during these operations. The process typically includes activities such as subsea welding, installation of subsea templates, and remotely operated vehicle (ROV) operations. Skilled professionals, including engineers and divers, work together to complete projects that support energy production and environmental monitoring beneath the surface.
