52000QR260003330 USCGC Daniel Tarr Hull Cleaning and Zinc Renew Annual Inspection

Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the requirements for underwater body and appendages inspection and cleaning for U.S. Coast Guard vessels.

• Inspection: Detailed procedures for inspecting hull plating, sea chests, rudders, fin stabilizers, bow thrusters, propellers, speed probes, zinc anodes, and cathodic protection systems. This includes checking for marine growth, corrosion, damage, pitting, obstructions, and fastener integrity.

• Cleaning: Procedures for cleaning hull plating, sea chests, rudders, fin stabilizers, bow thrusters, propellers, and cathodic protection components, focusing on removing marine growth and obstructions.

• Anode Replacement: Annual replacement of underwater zinc anodes is required.

• Environmental regulations (EPA) regarding the release of copper-based antifoulant paint must be followed, minimizing visible clouds or plumes in the water.

• Use of appropriate cleaning methods and tools to minimize environmental impact.

• Photographs and video footage are required for the hull and appendage inspection.

• Fouling Ratings (FR) are to be determined and recorded using Table 1.

• The document specifies annual replacement of zinc anodes.

• Maintenance is performed on U.S. Coast Guard vessels.

• Compliance with COMDTINST 9077.1 (series) for Equipment Lockout/Tags-Plus.

• Compliance with COMDTINST M3150.1D (series) Diving Program Manual.

• Use of Engineering Operational Sequencing System (EOSS).

• Contractors are responsible for providing necessary tools and test equipment.

• Environmental considerations for cleaning are paramount, requiring specific methods to prevent pollution.

Statement of Work (SOW)

This SOW outlines the requirements for conducting an underwater hull inspection, cleaning, and zinc renewal for the CGC DANIEL TARR.

• Inspection: Survey the entire underwater hull, including plating, coating system, transducers/sonar dome, drive systems, appendages, and cathodic protection system. This involves checking for marine growth, damage, corrosion, coating defects, and anode condition.

• Cleaning: Thoroughly clean the designated underwater hull surfaces free of marine growth, debris, and contaminants without damaging the existing coating system or non-coated surfaces.

• Zinc Renewal: Renew underwater zinc anodes as per specified Maintenance Procedure Cards (MPCs), including 12 additional stern tube zincs not detailed in the current MPC.

• Period: Between March 2-10, 2026.

• Place: USCG Base Galveston, 3000 FT Point RD, GALVESTON, TX 77550.

• Personnel: Must have trained personnel, including a certified diver and dive tender.

• Documentation: Requires detailed written reports (including specific forms for bio-fouling, hull inspection, running gear, propellers, rudders, and zincs) and an audio-video report with narration and linear measuring devices for scale. Documentation must be submitted within 24 hours of inspection completion.

• References: Work must adhere to Coast Guard Maintenance Procedure Cards (MPC B10015.D for inspection/cleaning and MPC B10018.D for zinc renewal), Coast Guard Drawings, SFLC Standard Specification 0000, and 29 CFR 1910, Subpart T (Commercial Diving Operations).

• Safety: Requires advance notice for inspections, pre-diving clearance, continuous two-way communication with divers, and adherence to safety protocols. Mixed gas diving and live boating are prohibited.

• Government Furnished Property: Specific anodes and fasteners are listed as government-furnished property.

• Cutter: EMCS Jared Guss (409) 600-2401, Jared.A.Guss@uscg.mil

• Norfolk Office (COR): Kevin O’Brien (571) 610-7557, kevin.p.obrien@uscg.mil

Form / Attachment / Pricing Sheet

This document, "WPC-154 B10018.D REV'D 05/31/23," is a U.S. Coast Guard Computerized Maintenance System (CMS) form detailing the "UNDERWATER ZINC ANODE REPLACE" procedure. It serves as a maintenance procedure and parts list for replacing zinc anodes on specific Coast Guard vessels (WPC-154 class).

• Maintenance Task: Replacement of underwater zinc anodes, including those for the bow thruster gear case, bow thruster tunnels, sea chest grates, and stern tubes.
• References: Lists relevant instructions such as COMDTINST 9077.1 (Equipment Lockout/Tags-Plus) and the Engineering Operational Sequencing System (EOSS).
• Tools/Test Equipment: Specifies necessary tools like wire twisters.
• Expendables & Consumables: Provides detailed lists of specific part numbers (P/N), CAGE codes, and NIINs for anodes, nuts, screws, washers, and wire required for the replacement.
• Procedure Steps: Outlines preliminary steps (parts request, service request, lockout/tag-out) and detailed replacement procedures for each anode location.
• Figures: Includes diagrams and images (Figures 1-8) illustrating the location and arrangement of anodes, propeller hub covers, and hub zinc plate wiring.
• Forms: References "Form 1" (Parts & Material Request/Use Form) and "Form 2" (Services Request Form) for ordering necessary parts and services.

This document is highly relevant for potential bidders involved in marine maintenance, repair, and overhaul services, particularly those specializing in U.S. Coast Guard vessels. It clearly defines the scope of work, required materials (with specific part numbers), and procedural steps for a critical maintenance task. Bidders can use this information to:

• Understand the technical requirements for anode replacement.
• Identify the specific parts and quantities needed.
• Assess the complexity and duration of the maintenance task.
• Prepare accurate bids and proposals for similar maintenance opportunities.
