About Western Branch Diesel, LLC

Western Branch Diesel, LLC, doing business as Western Branch Diesel Inc., is a for-profit limited liability company headquartered in Portsmouth, Virginia, that has been registered as a federal contractor since January 2002. The company specializes in the sale, service, and remanufacturing of marine diesel engines, transmissions, generators, and related equipment, with a particular focus on supporting federal maritime agencies. Western Branch Diesel maintains ten service locations across six states and serves as an authorized dealer for major marine equipment manufacturers including Detroit Diesel, MTU Friedrichshafen, Allison Transmission, and Volvo Penta. The company has established itself as a critical supplier and service provider to the U.S. Coast Guard, Department of the Navy, and other federal maritime agencies, leveraging specialized expertise in engine overhaul, remanufacturing, repair, and technical support to maintain operational readiness of federal vessel fleets.

Western Branch Diesel has demonstrated extensive capability in delivering diverse marine equipment and technical services through its federal contract portfolio. The company has received numerous purchase orders and delivery orders for engine repair, overhaul, and remanufacturing services, including Series 60 engine work, Detroit Diesel 6V92 engine remanufacturing, MTU engine overhauling, cylinder head inspection and repair, and propeller and gearbox services. Generator procurement and rental services represent a significant component of the company's federal work, with multiple blanket purchase agreement calls for generator rentals supporting submarine squadrons and naval facilities operations. The U.S. Coast Guard has been the primary funding agency for Western Branch Diesel's contract awards, with the Department of the Navy Naval Facilities Engineering Command and Naval Sea Systems Command also issuing substantial orders. Additional funding has come from the Air Mobility Command, U.S. Fleet Forces Command, and the National Oceanic and Atmospheric Administration. Western Branch Diesel has received contract awards both as a prime contractor and as a subcontractor to Lockheed Martin Corporation. The majority of awards have been firm fixed-price contracts without small business set-aside designations; however, the company has also been awarded several contracts designated as total small business set-asides, reflecting its qualification as a small business entity. Contract values have ranged from nominal amounts under one dollar for warranty programs to multi-million-dollar delivery orders, with individual orders frequently exceeding $100,000 and several exceeding $2 million.

Western Branch Diesel currently holds four active indefinite delivery contracts (IDCs) and blanket purchase agreements with federal maritime agencies. The company's largest IDC is a $26,097,716.36 multiple-award contract with the U.S. Coast Guard, awarded March 14, 2024, with an ultimate completion date of February 28, 2030, for the overhaul of MTU 60 series marine engines and attached Twin Disc reduction gears. Multiple delivery orders have been issued under this IDC, including orders valued at $2,048,445.00 for open inspection and reporting of engine mandatory parts and $2,192,603.18 for the overhaul of 18 engines. The company also holds a $5,638,350.02 multiple-award IDC with the Coast Guard, awarded January 27, 2022, expiring January 26, 2025, for the remanufacturing of MTU Detroit Diesel 6V92 Series marine engines. A single-award IDC valued at $2,640,540.95 was awarded by the Coast Guard on December 5, 2022, designated as a total small business set-aside, for the remanufacturing of MTU 60 series engines used on 45-foot RB-M vessels, with base and option periods extending through November 30, 2024. Additionally, Naval Sea Systems Command awarded Western Branch Diesel a $665,000 multiple-award Blanket Purchase Agreement on October 1, 2023, expiring September 30, 2028, enabling on-demand procurement of marine diesel engine sales, service, and technical support. These IDVs provide the Coast Guard and Navy with flexible, long-term contractual vehicles to procure critical engine maintenance, remanufacturing, and technical services necessary for maritime fleet operations and readiness.
