QuantiParts

What QuantiParts does

QuantiParts B.V. is a Dutch OEM (Original Engine Manufacturer) parts supplier headquartered in Hattem, Netherlands, that delivers genuine spare parts and lifecycle support for classic Wärtsilä engines. Established in May 2015 as the only Wärtsilä-established company with a complete independent organization dedicated to classic engine support, QuantiParts is a wholly-owned subsidiary of Wärtsilä Corporation. The company serves operators of aging diesel engines across three verticals: marine operators (commercial vessels, cruise ships), power plant operators (stationary power generation), and railway operators (diesel-electric locomotives and railcars). Its portfolio covers 13 engine brands and more than 50 engine types, including Bolnes, Deutz KHD/MWM, Stork Werkspoor Diesel (SWD), Sulzer A/S, Poyaud, SACM, Wärtsilä Vasa 14/24, Vasa 22/26, Wärtsilä 200/220, Nohab, Wichmann, Crepelle, and GMT engines.

The company's core capability is long-term lifecycle support for legacy engine platforms that Wärtsilä and its predecessor builders (Stork, Sulzer, Deutz, Poyaud, SACM, Bolnes, Nohab, Wichmann, Crepelle, GMT) historically produced. QuantiParts maintains an extensive inventory of new, remanufactured, and pre-owned genuine parts at a single central warehouse in Hattem with 24/7 order availability, and complements parts supply with a modern engine test bench facility (280–2200 kW, 1000–2350 rpm) for Factory Acceptance Testing and engine validation, plus field services delivered through its global distributor base.

QuantiParts generates revenue primarily through one-time sales of OEM spare parts, supplemented by professional services revenue from engine testing and field engineering work. Pricing is quote-based and handled through direct sales engagement. Distribution combines direct enterprise field sales organized regionally (Americas, Asia, Africa, North Europe, Middle East & Mediterranean) with a global network of dedicated QuantiParts Distributors and the parent Wärtsilä's service network. The company employs 51–100 people and relocated from its original Zwolle site to new, larger premises in Hattem in April 2024 to accommodate expected portfolio growth as additional Wärtsilä engine types are added to product responsibility.
