Advanced Subsea Services offers commercial diving and marine-construction support for pipelines, outfalls, cables, structures and vessels. Its published scope includes surface-supplied air, mixed-gas and saturation-diving services; underwater cutting and welding; repair and salvage; structural and video inspection; non-destructive testing; potable-water tank cleaning; and contaminated or confined environments. The project determines the personnel, equipment and procedure requirements.
A separate 16-foot mobile diving trailer is described for emergency ship-husbandry, repair and inspection callouts. The equipment list includes a decompression chamber, mixed-gas panel, communications, bailout equipment, HAZMAT gear, video and lighting, and cutting/welding tools. Its listed 300-foot umbilicals are diving-package dimensions, not a Falcon ROV depth rating. Company statements about WCB/CSA compliance and coded welding are not accompanied by current certificate or individual qualification scopes in the reviewed material.
Metro Vancouver's August 2024 award identifies C$78,700 for Crescent Beach discharge-pipe replacement diving services. For a historical delivery example, CADC's Summer 2017 feature describes the company's internal inspection assignment on a 9.5-kilometre North Surrey sewer and months of preparation for the hazardous and confined-space setting. The case supports relevant experience, while staffing and procedures for a new job need a current project package.
