Subsea Tech is one of the few ROV and USV inspection operators able to carry out a complete survey of a structure — water surface, submerged body and aerial section — in a single mobilisation. Our ROVs and USV catamarans are designed and manufactured in-house, ensuring the reactivity, reliability and data consistency that operators using third-party equipment cannot match. Our CATS-certified drone pilots also handle the aerial inspection of your structures.
Over 20 years of operations in France and internationally. More than 180 missions completed. Over 80 public and private clients trust us.
