Based in the United States, Peterson Power Systems, Inc. serves as the authorized Caterpillar dealer for a strategic expanse of the West Coast, specifically covering Northern California, Oregon, and southwest Washington. This wide geographic footprint places the company at the center of several critical maritime hubs, including the San Francisco Bay Area, the Columbia River system, and the rigorous Pacific coastline. Within the marine industry, the organization functions as a primary provider of propulsion engines, auxiliary power units, and marine generator sets, serving as a backbone for regional vessel operations.
The company supports a diverse spectrum of maritime clients, ranging from commercial shipping lines and articulated tug-barge operators to high-speed passenger ferries, commercial fishing fleets, and government vessels. By supplying heavy-duty power solutions, Peterson Power Systems facilitates the continuous movement of cargo and passengers throughout the Pacific Northwest and California. Their involvement often begins early in a vessel's lifecycle, where they act as a technical partner for naval architects and shipbuilders, ensuring that power systems are integrated effectively to meet specific performance requirements and hull constraints.
Operational support constitutes a significant portion of the company's identity. Recognizing the financial and logistical impact of vessel downtime, the organization maintains a network of marine-certified technicians and engineering staff capable of rapid deployment. These teams execute dockside maintenance, emergency diagnostics, and comprehensive engine overhauls directly at ports and harbors. Furthermore, the company assists vessel operators in navigating complex regulatory landscapes, particularly regarding emissions standards and engine repower projects aimed at modernizing aging fleets to meet stricter environmental protocols.
Established in 1936 by Howard Peterson, the enterprise began as a single location and has steadily expanded its territory and technical capabilities over nearly a century. Throughout its history, it has remained a family-led business while evolving into a substantial regional entity. This long-standing presence has allowed the company to develop deep ties within the local maritime communities it serves. Today, Peterson Power Systems operates as a vital component of the West Coast’s marine infrastructure, ensuring the reliability and efficiency of vessels operating in some of the most demanding aquatic environments in North America.
