Commercial Diving
ADCO’s expertise in civils diving lies in our ability to carry out precision underwater work. We offer expert service to engineering companies and other clients, to carry out precise and intelligent underwater inspections and subsequent reporting. Our civils team comprises experienced commercial divers, diving engineers, and other specialist divers, offering unique capability to observe, record and survey built installations underwater, assess damage and scour, and record impacts and structural deteriorations and defects. As with all ADCO work, we expect and ensure the highest quality of work and product delivery.
In addition, members of our dive-team have worked closely with ESBI to develop capability in the inspection and underwater repair of subsea electricity cables. These ADCO specialists are certified saturation divers who are capable of working at depths of up to 400m+ to carry out such work.
