subsea
Beneath ocean surface
Subsea describes things located or occurring beneath the surface of the sea, particularly in the context of offshore oil and gas operations: subsea pipeline, subsea drilling equipment, subsea wellhead.
The term is technical and industry-specific, distinguishing underwater infrastructure from surface platforms or onshore facilities.
The company specializes in subsea engineering.
