What Turbo Service International does

Turbo Service International (TSI) is a privately held UK-headquartered specialist in the repair, overhaul, and parts supply of marine and power-station turbochargers, founded in 1989 and operating from Southampton. The company serves two primary customer segments — international ship operators and management companies (covering main engines, auxiliary engines, and generator sets) and power-station operators — through purpose-built workshops in Southampton, Rotterdam, Houston, Genoa, and Malta, supported by sales offices in Glasgow, Piraeus, and Cyprus and strategic partners in Dubai, Hong Kong, Shanghai, Singapore, Turkey, and Cyprus. TSI's service portfolio combines OEM-standard maintenance and troubleshooting, a comprehensive parts inventory of new and reconditioned components, an exclusive worldwide NTN-SNR bearing distribution agreement in place since 2013, and a 24/7 emergency breakdown response with door-to-deck logistics.

TSI monetises through three revenue streams: professional service fees for repair and overhaul labour at OEM-trained engineer rates; hardware sales of new and reconditioned turbocharger components (rotors, cartridges, casings, bearings, pumps) backed by a 12-month worldwide warranty; and an exchange-cartridge program where customers return used units within two months for credit, preventing engine downtime. Distribution is hybrid: direct enterprise field sales from global offices, complemented by regional channel partners (SSRS Ltd in Greece, FactorShip in Germany, Brobs Marine partnership announced January 2025). The proprietary technical differentiators are specialist weld-repair and hot-metal-spray methods that restore turbine blades and shafts to original specifications at materially lower cost than OEM replacement, plus the exchange-cartridge inventory model. Headcount is reported at 11-50 employees, and the company is privately held with no disclosed funding rounds, parent company, or audited revenue.

Recent moves13 records

Expansion highlights5 records

Direct peers

• Accelleron (formerly ABB Turbocharging): Accelleron, spun off from ABB in 2023, is the world's largest independent turbocharger OEM serving marine, power and industrial markets. It is TSI's primary direct competitor, particularly in OEM-authorized service, new unit sales, and digital condition monitoring for installed fleets.
• KBB (Klein, Buse & Co.): KBB is a long-established independent German turbocharger specialist providing repair, overhaul and replacement units for marine and stationary applications. Closely comparable to TSI in product scope, customer base (shipping operators, power stations) and independent service positioning.

Broad incumbents

• MAN Energy Solutions: MAN Energy Solutions is a major German manufacturer of large two-stroke marine engines and turbochargers with a global service network. TSI frequently services MAN-designed turbochargers via OEM-trained engineers, so MAN's PrimeServ aftermarket network is both a feeder of work and a competing service channel.
• Mitsubishi Heavy Industries Turbocharger: MHI manufactures turbochargers used on many marine engines and operates an OEM service network. As a broad incumbent, it competes with TSI for high-end turbocharger service and parts, particularly on Japanese-built engines.
• IHI Charging Systems International: IHI is a Japanese turbocharger OEM with global marine and industrial coverage. Comparable to TSI as a turbocharger manufacturer and service provider, with broader scale and a stronger OEM-authorized service footprint.
• Wärtsilä: Wärtsilä is a Finnish marine energy and services major providing lifecycle service agreements that cover turbocharger maintenance alongside engines. Competes with TSI for integrated service contracts with ship operators, though its offering extends far beyond turbochargers.
• Caterpillar Marine: Caterpillar supplies marine engines and OEM turbocharger service through its global dealer network. Overlaps with TSI's customer base (ship operators, power stations) and competes on turbocharger repair and parts for Cat-powered vessels.
• BorgWarner: BorgWarner is a large US turbomachinery supplier with marine and industrial turbocharger exposure, primarily in medium-speed and high-speed applications. Comparable on technology and parts supply, though much broader in scope across automotive and industrial markets.

Regional players

• HD Hyundai Heavy Industries: HD Hyundai is a major Korean shipbuilder and engine manufacturer with growing marine service operations in Asia. Comparable as a regional service provider for marine engines and turbochargers, with strong coverage in Korean and Asian shipbuilding hubs where TSI relies on agents.
