PNSY Diesel Generator Maintenance
DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSEA.NAVSEA SHIPYARD.PORTSMOUTH NAVAL SHIPYARD GF · Response deadline: Thu, 15 Oct 2026
What the government is buying
The Portsmouth Naval Shipyard in Kittery, Maine, is soliciting offers for diesel generator maintenance. This is total small business set-aside procurement for repair and maintenance services on equipment critical to naval shipyard operations.
NAICS code 811310 covers Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance. This industry classification includes establishments that repair and maintain commercial and industrial machinery such as engines, turbines, and power transmission equipment. Diesel generators at a naval shipyard fall squarely within this scope—organizations in this field typically service prime movers, auxiliary power units, and related components that support shipboard or facility electrical systems.
As a NAVSEA shipyard facility, Portsmouth Naval Shipyard performs nuclear submarine maintenance, repair, and modernization. Diesel generators serve as essential backup and auxiliary power sources for shipyard operations, dry dock facilities, and potentially for submarines undergoing maintenance. Work of this nature generally involves routine servicing, troubleshooting, parts replacement, overhaul, and compliance with naval technical specifications.

Who can bid
Only small businesses under NAICS 811310 can compete for this award. The Small Business Administration size standard for this code is typically $8.0 million in average annual receipts (verify current thresholds at SBA.gov).
To qualify, your business must:
- Be registered and active in SAM.gov with 811310 in your profile
- Be classified as "small" under SBA receipts-based standards
- Demonstrate relevant diesel engine or generator maintenance experience, preferably in maritime, industrial, or federal environments
- Hold or be able to obtain any required facility clearances, trade certifications, or Navy-specific qualifications
If you are a veteran-owned, woman-owned, HUBZone, or 8(a) small business, you may still bid under this total small business set-aside, though no specific socioeconomic preference beyond small business status is indicated in the metadata.
How to put together a competitive bid
For shipyard machinery maintenance contracts, successful bids typically emphasize technical capability, past performance, and operational readiness:
- Personnel qualifications: Highlight certified diesel mechanics, marine engineers, or Navy-experienced technicians. MILSPEC familiarity and security clearance capacity are often evaluated factors; see the solicitation for specific requirements.
- Past performance: Reference comparable contracts—especially NAVSEA, other military shipyard, or commercial marine generator work. Include contactable past performance references with similar scope and complexity.
- Technical approach: Address how you will perform maintenance with minimal operational disruption. Shipyard schedules are mission-critical; demonstrate understanding of production pacing, emergency response capability, and parts availability.
- Pricing strategy: Combined synopsis/solicitation notices often involve simplified acquisition procedures. Review whether this is an RFQ with line-item pricing or a more complex RFP requiring cost narratives.
- Compliance: Verify your SAM registration expiration, confirm small business size status representations, and ensure any required OSHA, environmental, or specific Navy certifications are current or obtainable.
