MSHS Pacific Power Group

What MSHS Pacific Power Group does

MSHS Pacific Power Group is a private industrial MRO service provider specializing in the servicing, design, and sale of power and propulsion systems for power generation, industrial, marine, and national security customers. Founded in 1958 as Pacific Diesel Power Company in Portland, Oregon, the company evolved through multiple rebrands and acquisitions, integrating as MSHS PPG in 2022 and being acquired by Industrial Service Solutions (a Wynnchurch Capital portfolio company) in February 2026. The company operates 10+ full-service workshops across Alaska, California, Florida, Hawaii, Louisiana, and Washington, supported by 450+ technical and staff and 150+ OEM authorizations including Rolls-Royce (MTU), Woodward, Volvo Penta, Napier, and Bergen.

The company's core technology portfolio spans 2-stroke and 4-stroke diesel, gas, and multi-fuel engines; generator sets; turbochargers; governors and actuators; control systems and automation; fuel/oil/water/air management; emission abatement systems; and auxiliary components. Service offerings include field, onsite, and workshop-based maintenance, repair, overhaul, technical support, training, engineering design, predictive maintenance, diagnostics, and upgrades/retrofits. Revenue is generated through professional services (labor-based MRO), parts and component sales under unit pricing, and government contracts — notably an IDIQ contract with the U.S. Navy's Military Sealift Command carrying a ceiling of up to $759 million through June 2031.

The go-to-market motion is enterprise field sales and direct account management, organized around three primary business segments: Power Generation & Industrial (power plants, utilities, data centers, hospitals, pulp and paper mills, supermarkets), Marine (yachts, tug/push boats, container ships, cruise ships), and National Security (U.S. and international military vessels, defense facilities). Pricing is quote-based and not publicly disclosed; customers are billed under 30-day payment terms for credit-approved accounts, with a $200 Fast Lane surcharge for urgent orders processed within 24 hours. The company is led by President/CEO David A. Santamaria, CFO Shaun Fuller, VP Marine & Defense Douglas Schwedland, and VP Power & Industrial Pete Jacobs.

Broad incumbents

• Rolls-Royce Power Systems (MTU): OEM of MTU diesel and gas engines for marine, power, and defense applications. Also a core partner of MSHS PPG for authorized servicing; competes via its own global service network while relying on MSHS PPG for regional MRO coverage in the U.S.
• Volvo Penta: OEM of marine and industrial diesel engines with a global authorized service dealer network. Both a partner of MSHS PPG and a competitor for Volvo Penta engine MRO in marine and power generation applications.
• Cummins: Global manufacturer of diesel and gas engines, generator sets, and power systems with extensive direct service capabilities. Competes with MSHS PPG in standby/prime power, marine, and industrial engine MRO across commercial and defense end markets.
• Caterpillar Marine Power & Energy: Caterpillar's marine and power generation engine division sells and services heavy-duty diesel/gas engines for vessels, offshore, and prime/standby power, directly overlapping MSHS PPG's product lines and competing in the same end markets through Caterpillar's dealer network.

Direct peers

• Fairbanks Morse Engine: U.S.-based manufacturer and service provider for heavy-duty diesel and dual-fuel engines serving naval, marine, and power generation markets. Direct overlap with MSHS PPG's National Security and Power Generation segments, including military vessel propulsion MRO.
• Goltens: Independent global provider of marine engine and component MRO services serving commercial shipping, offshore, and naval customers. Closest independent-MRO analog to MSHS PPG with comparable field service and workshop capabilities for diesel/gas engines and auxiliaries.
• Wärtsilä: Finnish global OEM and service provider for marine engines and power generation, directly competing with MSHS PPG in ship propulsion MRO and power plant engine services. Wärtsilä also operates lifecycle service agreements that overlap with MSHS PPG's maintenance offerings.
• MAN Energy Solutions: Major marine engine OEM and service provider serving the same commercial shipping, naval, and power generation customers as MSHS PPG. Operates a global PrimeServ service network that competes directly with MSHS PPG's marine and power generation MRO capabilities.

Others
