Marine Engineering and Construction

Associated Diving Services has a fully trained and vastly experienced workforce that is able to work on any marine or river-based project. In tidal estuaries, such as the Milford Haven Waterway, a highly professional approach is paramount due to the hazardous nature imposed by limited exposure of work areas due to the tide and the risks of fast moving currents. Add into the equation that many coastal sites are exposed to extreme weather conditions, especially in the winter months, and it becomes evident why ADS’s 25 years of experience in the marine environment can be vital in any project.

All our divers are directly employed and trained to a minimum of HSE Part 3 or equivalent standard, and the company is a member of the Association of diving contractors.

All diving work is undertaken in accordance with the diving operations at Work Regulations and the Inshore/Inland ACOP.

Associated Diving Services has a long-established reputation and experience in the field of diving and Sub-Sea Engineering.
