IMMERSUB LIMITED is a specialized maritime contractor providing commercial diving and subsea engineering services. Based in the Indian Ocean region, the company is recognized as the oldest established commercial diving entity in Mauritius. Since its incorporation in 2004, it has evolved from a family-run operation into a key regional provider of underwater ship husbandry and emergency marine support. Founded by a former merchant ship captain and a certified commercial diver, the organization combines deep operational knowledge of dry-dock management with technical subsea expertise.
The company primarily supports shipowners, vessel management agencies, and maritime insurers by maintaining the operational efficiency and safety of vessels. Its core activities center on underwater hull cleaning, propeller polishing, and general maintenance, which are critical for optimizing fuel consumption and reducing vessel drag. IMMERSUB LIMITED has adopted environmentally conscious practices, utilizing advanced remotely operated vehicle (ROV) technology to perform hull cleaning without releasing biofouling or pollutants into the marine environment. This focus on eco-friendly solutions aligns with global regulations regarding invasive species and marine preservation.
Beyond routine maintenance, the company conducts comprehensive underwater inspections and surveys. It holds certifications from multiple members of the International Association of Classification Societies (IACS), allowing it to perform class-approved in-water surveys, damage assessments, and pre-sale inspections. These operations often involve real-time CCTV monitoring and digital imaging to provide transparency to remote surveyors and superintendents.
IMMERSUB LIMITED also plays a significant role in emergency response and salvage operations within the Indian Ocean. The company maintains readiness to assist with casualties, including grounding incidents and collision damage. Its teams are experienced in underwater cutting, welding, and sea chest blanking, as well as complex tasks such as oil spill containment. During major maritime incidents in the region, the company has deployed resources to install containment booms and conduct pollution control measures, serving as a first responder for environmental protection.
With a strong emphasis on safety and compliance, the company manages a team of certified divers and technicians who execute both inshore and offshore projects. By integrating traditional diving skills with modern hydraulic equipment and robotic systems, IMMERSUB LIMITED supports the continuous flow of maritime commerce through the strategic waterways of Mauritius and the surrounding ocean.
