Based in Australia, Commercial Diving Services is a long-standing marine contractor specializing in underwater inspection, construction, maintenance, and salvage operations. Established in 1955 by Neil Johnson, the company is deeply rooted in the Australian maritime sector, having operated as a family-owned business across three generations. It is widely recognized for its pioneering role in the region’s commercial diving industry, evolving from early manual diving techniques to a modern operation utilizing advanced subsea technology.
The company primarily services the shipping, civil engineering, and offshore industries, providing a comprehensive range of underwater solutions. A significant portion of its operations focuses on ship husbandry and asset preservation. These services include underwater hull cleaning to improve vessel fuel efficiency, propeller polishing, and in-water class surveys that allow vessel operators to assess structural integrity without dry-docking. The company also handles complex bio-security inspections, ensuring vessels comply with environmental regulations regarding marine growth and invasive species.
Beyond vessel support, Commercial Diving Services manages substantial infrastructure projects. Its certified dive teams perform maintenance on marine structures such as wharves, bridges, and jetties, as well as inland assets like dams and reservoirs. Technical capabilities extend to underwater wet welding, thermal cutting, drilling, and concreting, allowing the company to execute heavy construction and repair tasks beneath the waterline. To support these activities, the firm utilizes a fleet of specialized equipment, including remote-operated vehicles (ROVs) for deep or hazardous inspections, hydraulic tools, and portable decompression chambers.
The organization maintains a high degree of mobility, designing much of its equipment for rapid deployment via road or sea to remote locations throughout Australia and the South Pacific. This logistical capability supports its 24/7 emergency response service, which is frequently engaged for marine salvage and urgent asset recovery. The company emphasizes strict adherence to safety and quality protocols, employing Australian Diver Accreditation Scheme (ADAS) certified personnel to mitigate the high risks associated with subsea environments. Through its decades of operation, Commercial Diving Services has maintained a continuous presence in the maritime sector, supporting both commercial shipping fleets and critical public infrastructure.
