ASI Group

ASI Group operates as a prominent engineering and marine services provider, originally established in Canada under the name Aquatic Sciences Inc. Since its founding in 1987, the organization has dedicated itself to the assessment, maintenance, and rehabilitation of underwater infrastructure. Unlike generalist maritime firms that focus on surface logistics, this company occupies a specialized technical niche at the intersection of marine engineering and biological management. Headquartered in Ontario with additional operations across the United States and South America, the firm addresses the complex challenges associated with submerged assets in both coastal and inland environments. The core of the company's identity revolves around its capability to access and inspect difficult-to-reach marine structures. To achieve this, the firm utilizes a hybrid operational model that combines commercial diving teams with advanced robotic systems. Their fleet includes remotely operated vehicles (ROVs) and autonomous underwater vehicles designed for specific tasks, such as long-range tunnel inspections and deep-water surveys. These robotic assets allow the company to navigate hazardous marine conditions, including confined spaces and zero-visibility environments, to gather critical structural data using sonar and video telemetry. When physical intervention is required, their certified commercial divers execute underwater welding, concrete repair, and hyperbaric construction tasks. A defining characteristic of their role within the maritime and industrial sectors is their specialized expertise in biofouling management. The company has developed extensive protocols for controlling invasive aquatic species, particularly zebra and quagga mussels, which frequently colonize water intake structures and ship piping systems. This biological focus complements their engineering services, as they not only repair physical damage but also design and implement treatment systems to mitigate the environmental factors that degrade marine assets over time. The organization serves a diverse client base that includes power generation utilities, heavy manufacturing industries, and municipal water authorities that rely on large-scale marine intake and outfall systems. By integrating hydrographic surveying with mechanical and biological intervention, ASI Group provides a comprehensive approach to underwater asset preservation. Their workforce consists of a multidisciplinary team of marine biologists, professional engineers, and technical specialists who collaborate to ensure the continuous operation of essential facilities submerged in aquatic environments. Through these specialized activities, the company plays a vital role in extending the lifespan and safety of critical underwater infrastructure.
