The increasing adoption of advanced autonomous underwater vehicles (AUVs) and uncrewed surface vessels (USVs) for subsea inspection, survey, and data acquisition represents a clear emerging threat. Companies specializing in these highly automated solutions offer significantly lower operational costs, reduced carbon footprints, and minimal personnel exposure compared to Oceaneering's traditional work-class remotely operated vehicle (ROV) operations that typically require a large, crewed support vessel. This shift towards more efficient and autonomous subsea operations could erode demand for Oceaneering's established ROV services market as clients increasingly prioritize cost efficiency and environmental impact.
