Motortech Consulting

What Motortech Consulting does

Motortech Consulting d.o.o. is a Croatian privately held limited liability company founded in 1994 as a spin-off from Uljanik strojogradnja's high-speed engine production department, headquartered within the Uljanik shipyard in Pula. The company manufactures diesel-electric generator sets in a 30 to 2,500 kWe power range for both marine programs (emergency and auxiliary power systems for cargo ships, ferries, cruise vessels, offshore platforms) and land programs (banks, sports venues, public buildings). The technical architecture pairs Isuzu, MAN, Mitsubishi, Deutz, MTU, and Caterpillar diesel engines with Stamford, TESU, Sincro, and Leroy Sommer generators, integrated with Vulkan couplings, Danfoss/Bedia sensors, ComAp engine monitoring, and Schneider electric equipment; the company also produces its own MT-branded heavy-duty marine engine on an Isuzu technology base (e.g., MT 2.2 IDI, 49 hp at 2,600 rpm).

The business operates four revenue streams: (1) project-based diesel-electric generator manufacturing under Bureau Veritas-classified tenders, with individual contracts often exceeding €1 million (GMKH Limited Malta at €3.5M plus a €0.9M follow-on, Lukoil Caspian Sea at €1.1M, Greek Fire Service at €1.2M+); (2) marine and nautical equipment sales via a Pula retail showroom and authorized dealerships for Isuzu marine engines across Southeast Europe and Griffin filtration products in Croatia; (3) servicing, diagnostics, testing, installation, and reconstruction for diesel engines, generators, high-pressure fuel pumps, turbochargers, and marine equipment, supported by mobile service; and (4) equipment rental including resistive load banks and portable diesel power generators (100 to 500 kW). Customers span shipbuilders (Tehnomont Pula, HALONG Vietnam, 3. Maj Shipyard), offshore oil and gas operators (Lukoil on the Vladimir Filanovsky Field), government and defense (Greek Fire Service, Brijuni National Park), banking and commercial real estate (Zagrebačka banka, Privredna banka, Arena Zagreb), and luxury yachting (Ecstasea, Pershing, Prince of Venice). Approximately half of revenue is international, spanning 40+ countries, with co-developed hybrid diesel-electric propulsion (with Tema d.o.o.) and active positioning at METSTRADE Amsterdam, NEVA St. Petersburg, and the Genoa International Boat Show. Motortech also executive-organizes the Pula Boat Fair and holds a regulatory moat through its Bureau Veritas Mode II Scheme and HRB certifications.
