This is a U.S. Coast Guard Computerized Maintenance System (CMS) form for documenting underwater zinc anode replacement maintenance on WPC-154 class vessels (Revision dated 05/31/23).

The document provides comprehensive procedural guidance for replacing sacrificial zinc anodes across multiple vessel systems including the bow thruster gear case, bow thruster tunnels, sea chest grates, stern tubes, and propeller hub covers. The maintenance procedure is designated CMS Code B10018 with CEINUM P3-B000-001 and requires completion by professional divers only. Key preliminary steps mandate equipment lockout/tag-out compliance per COMDTINST 9077.1 and placement of Red Danger Tags on approximately 18 specified electrical systems and mechanical components throughout the vessel. The procedure specifies detailed parts requirements including multiple anode part numbers (P/N 1081226 for gear case, P/N 2002416 and CM2000Z for tunnel anodes, P/N GA-4 for sea chest grates, P/N Z0020202H3 for stern tubes, and P/N 950733 for propeller zinc plates), along with associated hardware such as self-locking nuts, washers, screws, and safety wire. Hull-specific variations are documented, distinguishing between Hulls 1101-1132 (originally welded anodes retrofittable to bolted style per MPC B10017.D), Hulls 1133-1144 (12 bolted tunnel anodes per side), and Hulls 1145-on (6 bolted tunnel anodes per side). The form includes technician man-hour tracking fields for nine different military specialties (MK, DC, EM, ET, IT, GM, BM, FN, SN, ME) and requires Quality Assurance review where indicated. Final steps include removal of lockout tags, return of operating components to normal positions, equipment readiness restoration, and submission of anode deterioration rate documentation to the Engineering Program Officer (EPO). Two supporting forms are provided: Form 1 (CG-4491 Parts & Material Request/Use Form) for ordering required components and Form 2 (Service Request Form) for coordinating contracted diver services through the Program Depot Maintenance organization.

A PRELIMINARY STEPS

NOTE: Hulls 1101-1132 were originally equipped with welded anodes in the B/T tunnel. If you do not have the retrofit on your hull do not order the B/T tunnel anodes. Hulls 1133 and on will have the B/T tunnel anodes bolted on to provide the capability to replace while the cutter is waterborne. Hull 1145 and on will have six anodes per hull, three anodes per side. The same hardware is used on all bolt-on anodes.

NOTE: MPC B10017.D provides the authority to retrofit hulls 1101- 1132 to the new bolted style as the cutters are dry-docked. Once completed the cutters configuration will be updated for tracking pur-poses.

NOTE: Self-locking nut has a unit of issue of 25 each. The MPC total required is 36 each. Only two are required to be purchased.

NOTE: Sea chest grate anode screw has a unit of issue of five each.

The MPC total required is four each. Only one is required to be pur-chased.

NOTE: Parts should be ordered by removing and using the parts re-quest Form 1 of this MPC. Draw a line through any parts that may not be required. Fill in the remainder of required information including quantity and forward the parts request to your Asset Material Man-ager (AMM) or Supply department for processing.

1. Complete the parts request form, (Refer to Form 1).

NOTE: Services should be ordered by removing and using the ser-vice request Form 2 of this MPC. Fill in the required information and the forward service request form to your ProgramDepot Maintenance (PDM) (APM) for processing.
