DRAFT

STATEMENT OF WORK (SOW)

1. GENERAL INFORMATION:

1.1. GENERAL: This is a non-personnel services contract to provide thermal spray repair technical services to a submarine induction mast standpipe upon approved CFR. The Government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the Contractor who, in turn is responsible to the Government.

1.2. DESCRIPTION OF SERVICES/INTRODUCTION: The contractor shall provide all personnel, facilities, equipment, supplies, transportation, tools, materials, supervision, other items and non-personal services necessary to perform thermal spray repair services to the submarine induction mast standpipe as defined in this Statement of Work (SOW), except for those items specified as government furnished material, property and services.

The contractor shall perform to the standards in this contract.

1.3. BACKGROUND: Trident Refit Facility, Bangor, WA (TRFB), in support of the SSBN 737 USS Kentucky Extended Refit Period (ERP) maintenance availability, requires commercial thermal spray surface deposition repair services to restore the Induction Mast Standpipe outer surface as directed by Ref. 2.1. The outer surface of the Induction Mast Standpipe requires outer “wear” surface repairs due to wear and corrosion by products and defects that do not meet inspection criteria of the applicable NAVSEA Maintenance Standard document. Thermal spray repair of components removed from USN vessels shall only be conducted by thermal spray entities whose deposition processes and facilities have been certified by NAVSEA.

1.3.1. The Induction Mast Standpipe outer wear surface was previously repaired in 2012 via thermal spray repairs conducted by Norfolk Naval Shipyard (NNSY) per Ref.

2.1. When TRFB engaged NNSY in FEB 2026 to query as to their capability to assist with thermal spray repair services, NNSY responded that they do not currently have the capability. TRFB then surveyed other USN shipyards, which resulted with no activity having the requisite thermal spray capability, thus commercial thermal spray services are required.

1.4. SCOPE: Current baseline conditions: SSBN 737 USS Kentucky Induction Mast Standpipe is removed from ship and is in shop to facilitate engineering inspections, issuance of repair direction, and conduct of repair actions.

1.5. PERIOD OF PERFORMANCE: 01 MAY 2026 through 31 JUL 2026

1.6. LOCATION OF WORK: Contractor Facility; CONUS.

1.7. TYPE OF CONTRACT: Government will award a Firm-Fixed Price Contract.

1.8. TECHNICAL CLARIFICATION: All technical clarifications will be coordinated through the Contracting Officer’s Representative (COR).

1.9. GOVERNMENT POINT OF CONTACT: Contracting Officer’s Representative (COR) identified in contract.

1.10. SHIPPING AND DELIVERY: Coordinate delivery and shipment of Government Furnished Equipment (GFE) with the COR. See below for clarifying delivery and shipping information:

1.10.1. Freight and shipping, by traceable means, of the Induction Mast Standpipe from TRFB to the contractor is the responsibility of, and funded by, TRFB.
