HARDSUIT™ ADS

 

OceanWorks International offers offshore subsea intervention services using the HARDSUIT™ Atmospheric Diving System (ADS).

      

 

OceanWorks is a member of the International Marine Contractors Association (IMCA) and operates the ADS in compliance with IMCA guidelines and requirements. 

 

       

 

The HARDSUIT™ ADS has been used extensively in both commercial and military applications, and offers a unique and cost effective solution for completion of many underwater tasks in depths of up to 360 meters (1200) feet. US Navy versions of the HARDSUIT™ have been configured for depths of 610 m (2000 ft). Smaller crew sizes, reduced training requirements, no decompression, unlimited vertical excursions, system portability, and lower capital equipment costs are some of the advantages the ADS has over traditional diving. 

The ADS also has many advantages over ROV technologies. It provides better access to confined spaces, 3D perception, improved dexterity, and has the ability to use standard diver tools and equipment without the expensive pre-engineering required for ROV operations.

 

 

The HARDSUIT™ maintains the operator in a safe, one atmosphere environment throughout the water column, eliminating significant physiological factors that affect saturation divers. The HARDSUIT™ also allows for the following capabilities:

•Maintain clear voice communication at all times

•Make unlimited vertical excursions without concern for decompression

•Return to the surface at any time to consult with supervisory personnel and then return to the job site without changing pilots or losing time for personnel change over.

•Return to the surface immediately on completion of the task without decompression delay

•Consume smaller deck space on surface vessels, with lower weights than saturation diving or ROV systems

Certification and Safety Reccord 

All systems, pilots and technicians are trained to internationally recognized standards. OceanWorks maintains an alliance with the Underwater Centre Fermantle (UTCF) for provision of fully accredited ADS personnel training. A typical ADS crew for a 12 hour shift consists of six people (one Supervisor, two pilots and three Technicians). For projects requiring 24 hour per day operation, one Superintendent is added to coordinate the two six person shifts. Additional project management, equipment, specialists and engineers are added as required depending on the scope of work.
