About this opportunity
The Department of the Navy Military Sealift Command intends to issue an out-of-scope modification to contract N3220524C4021 to add harbor tug services for tow mission 626 at Naval Prospective Training Unit in Charleston, South Carolina, on a sole-source basis to Moran Towing Corporation.
The modification addresses a tow mission scheduled for August 2026, anticipated to require 5 to 9 days including travel time, though the actual operational mission will span 4 to 8 hours. The requirement calls for two fully-crewed U.S. Flag submarine-fendered tugs to provide undocking and river transit support; the Paul T. Moran is identified as the only known commercially available vessel meeting specifications.
The justification rests on severe scarcity of specialized equipment. Only three East Coast providers—Moran Towing Corporation, Thames Towboat Company, and Alpha Marine Services—possess purpose-built harbor tugs with non-marking rubber fendering below the waterline required to protect submarines from hull damage. This limited supply was further consolidated when Moran Towing acquired Bisso Towboat Company in October 2025. A Sources Sought notice (SS-26-098) posted to SAM.gov April 24–28, 2026, yielded responses indicating only one responsible source could fulfill the requirement; two other offerors expressed interest but failed to propose suitable vessels or provide adequate documentation. The Contracting Officer determined fair and reasonable pricing through comparison to historical prices paid and market research per FAR 15.404-1(b)(2). Authority cited is 41 U.S.C. 1901. Place of performance is Charleston, South Carolina, outside the contract's defined geographic region of Norfolk, Virginia.
