Mitsubishi Heavy Industries Compressor Corporation (MCO), part of the Mitsubishi Heavy Industries (MHI) Group, has acquired all shares of AST Turbo AG, a Swiss company specializing in rotating equipment maintenance services, effective February 27, 2026. MCO said the deal is intended to strengthen its field service system in international markets.
AST provides maintenance, inspection, and field services for rotating equipment such as compressors and steam turbines that drive compressors. The company supports resource and energy development sites, including in the oil and gas sectors, and has executed projects in Europe, North America, the Middle East, and other regions worldwide.
MCO cited growing customer requests for shorter turnaround times for parts replacement, repairs, and inspections following turbo machinery installation, alongside shorter inspection intervals to improve equipment uptime. The company also pointed to increased demand for virtual assembly technology and the deployment of experienced technical supervisors.
AST’s engineering capabilities include virtual assembly technology using 3D laser measurement. MCO said it has a long-established collaborative relationship with AST and has jointly provided field service on several projects; following the acquisition, AST will continue under the leadership of its current management team while integrating MCO’s and the MHI Group’s technological expertise and know-how to enhance service quality and expand business operations.
MCO described the acquisition as an example of partnering initiatives promoted by the MHI Group and said it will continue to build strategic partnerships globally to incorporate external expertise and deliver its technologies, products, and services to a wider range of customers.
