T-ESD and ESB Class Alteration Design Support

The Department of the Navy Military Sealift Command anticipates procuring T-ESD and ESB Class alteration design support services and is conducting market research through a sources sought notice with capabilities submissions due September 14, 2026. No set-aside is anticipated.

The contractor must develop three TRANSALT (Transportation Alteration) work packages over a 32-week period, delivering engineering design and technical documentation across naval architecture, electrical, mechanical, and structural disciplines. Work includes detailed ship checks on one T-ESD Class vessel and one ESB Class vessel, followed by comprehensive packages containing engineering calculations, contract guidance drawings, bills of materials, cost estimates, weight reports, test procedures, technical manuals, and spare parts lists. The three specific projects involve upgrading ESB Class sludge transfer pumps to double capacity using air-operated positive displacement pumps; modernizing engine room bridge crane components by replacing obsolete rotary limit switches; and replacing two-stage reciprocating piston starting air compressors with rotary screw compressors featuring remote operation capability from the IACMS system.

All deliverables must comply with American Bureau of Shipping rules, USCG regulations, SOLAS/IMO requirements, and applicable federal standards, with drawings prepared in AutoCAD LT 2021 and technical documents in MS Word 2016. The contractor must assign qualified key personnel: a Project Manager with minimum 5 years multi-disciplinary shipboard experience and B.S. degree; Lead Electrical Engineer with B.S. in Electrical Engineering and 5 years marine electrical design experience; Lead Mechanical Engineer with B.S. in Engineering and 5 years marine mechanical experience; Lead Naval Architect/Structural Engineer with B.S. in Naval Architecture/Structural Engineering and 5 years related experience; and a separate QA Engineer with 5 years related experience (non-dual-hatted). Small businesses, Service-Disabled Veteran-Owned Small Businesses, HUBZone firms, Women-Owned Small Businesses, and 8(a) Small Businesses are encouraged to submit capabilities packages not exceeding 10 pages.
