About this opportunity
The Department of the Navy Military Sealift Command intends to issue an out-of-scope modification to contract N3220525C4019 on a limited-sources basis to add a harbor tug for a tow mission at Naval Submarine Base Charleston, South Carolina, outside the contract's authorized geographical region of Kings Bay, Georgia and Mayport, Florida.
The contracting officer determined that only three East Coast providers possess purpose-built harbor tugs with the specialized submarine-fendering and propulsion systems required for naval vessel movements: Moran Towing Corporation, Thames Towboat Company, and Alpha Marine Services. This limited pool was further consolidated in October 2025 when Moran Towing acquired Bisso Towboat Company. A Sources Sought notification posted to SAM.gov on April 24, 2026 identified no additional responsible sources capable of meeting the requirements. The tug will be needed for 5–7 days including travel time, with the actual towing operation estimated at 4–8 hours, anticipated for August 2026. The tug must be fully crewed and U.S. Flag with specialized nonmarking rubber fendering designed to protect submarines from hull damage. The contracting officer determined the anticipated cost fair and reasonable through comparison to previous purchases and independent government cost estimates per FAR 15.404-1(b)(4) and (b)(5). Place of performance is Charleston, South Carolina.
