Motorenrevisie Spaarnestad

What Motorenrevisie Spaarnestad does

Motorenrevisie Spaarnestad is a privately held Dutch diesel engine overhaul and repair specialist founded in 1986 in Heemstede and now operating from a purpose-built facility on the Waarderpolder industrial estate in Haarlem, Netherlands, with a 150-meter quay on the River Spaarne. The company serves maritime, superyacht, offshore oil and gas, industrial, and automotive customers with complete engine overhauls, maintenance, fuel injection service, and custom fabrication — most prominently on MTU, John Deere, Yanmar, Cummins, Bosch, Delphi, and Denso engine families. It operates a wholly-owned automotive subsidiary, BDC Spaarnestad Autoservice (formerly under Bosch Car Service from 2018 to 2025), and a Mediterranean service point in Palma de Mallorca for superyacht support.

The company's technical platform is built around in-house industrial equipment: a Rottler EM109H CNC machine (1700x6100mm bed) for line boring and surfacing of large engine blocks; five Hartridge and Bosch fuel injection test benches (EPS-200, DCI-700 up to 2500 bar, AVM2-PC, CRI-PC 4 Liner, EPS-815) for injector and pump calibration across common rail, in-line, and rotary systems; a 2400kW water brake test bench witnessed by classification societies BV, LR, DNV GL, ABS, RINA, and RR; a Narran laser cleaning system acquired in 2021; 3D scanning for exhaust system redesign; a Kardex vertical storage system installed in 2015 housing roughly 80% of parts inventory; and an in-house developed governor test stand for MTU1163 and MTU595 units. The firm holds authorized service center status with MTU, Bosch Diesel, Delphi, John Deere, Yanmar, Zenoro, and Balmar.

Revenue is generated entirely through professional services — engine overhauls, fuel injection testing and repair, governor rebuilding, field-service dispatch, and parts sales — supplemented by a small retail automotive lane at BDC Spaarnestad Autoservice. Pricing is quote-based and not publicly disclosed. The business is founder-led (Carl Scholtemeijer and Hans Kruijer), privately held with no external institutional investment, and operates with 11–50 employees. Geographic reach is anchored in the Netherlands with documented projects extending to Spain, the Middle East, and offshore North Sea platforms, supported by international courier logistics and field-service vans.
