Class” cutters, Weldox 900 steel plating has been approved as a replacement for HY-130. Due to the similarity in material properties and weldability of HY-130 and Weldox 900, all welding procedures and welder qualifications for welding Weldox 900 shall be the same as those outlined in NAVSEA TP 1688 as applicable for welding HY-

130.

3.4.2 Standard spec modification. For any welding involving HY-130 on the flight deck of WMEC-270 “B-Class” cutters, perform all welding and allied processes, and non-destructive testing/inspection (NDT/NDI) in accordance with NAVSEA TP 1688. The Contractor shall be aware that the welding requirements specified in this document take precedence over paragraph 3.3.6 of SFLC Standard Spec 0000 for the purpose of welding involving HY-130.

3.4.3 Approval to weld HY-130. To obtain Coast Guard approval to weld on HY-130 steel for WMEC-270 “B-

Class” cutters, the Contractor shall provide written Performance Qualification Records (PQR’s) for each process to be used. The PQR’s shall be approved by one of the regulatory agencies affirming that the WPS meets the welding requirements of NAVSEA TP 1688. In addition, the Contractor shall ensure that all subcontractors, prior to performing welding operations, have qualified procedures by meeting all the requirements set forth in this document.

3 (Rev-0)

NAVSEA approval is NOT required for welding procedures submitted but the procedures must be reviewed and shown to satisfy the requirements set forth in

NAVSEA TP 1688, by a welding regulatory agency. The requirements for welding

Weldox 900 shall be considered the same as those for welding HY-130.

3.5 Cleaning requirements. The Contractor shall clean all interior and exterior heat transfer surfaces to a state free of all debris, scale and surface contaminants in accordance with the heat exchanger manufacturer’s recommendations, and in compliance with all Federal, state, and local environmental regulations. Ensure that chemical cleaners do not damage the environment, heat exchanger or the vessel.

14 (Rev-0)

Historically, chemical cleaning has been necessary to thoroughly clean most heat exchanger tubes.

3.6 Pipe flushing. The Contractor shall flush all new and disturbed piping with clean fresh water until all debris is removed but no longer than five minutes. Ensure flushing fluid is directed to move scale and foreign debris away from installed machinery to prevent possible damage upon operational testing.

Submit a CFR documenting date and time of flushing process and level of pipe cleanliness.

3.6.1 Dispose of flushing fluid in accordance with all applicable Federal, state, and local regulations.

WARNING

Do not drain any fluids including fresh water, into any space, bilge, or exterior location.

3.7 Reassembly. After authorized repairs, if any, the Contractor shall reassemble each heat exchanger.

3.7.1 Renew all software (seals, gaskets, O-rings, lantern rings).

3.7.2 Renew isolation fittings/mounts and fasteners if disturbed. Apply silicone rubber sealant conforming to CID A-A-59588 around all fasteners, nozzles or gaskets that penetrate the hull.

3.7.3 Renew all hoses, thermostats and anodes as applicable.

NOTE

See related work item “Lube Oil Heat Exchangers; Clean, Inspect And

Hydro” so work can be coordinated to minimize loss/renewal of jacket water.

3.7.4 Refill all heat exchanger fluid levels, including all jacket water in all disturbed engines and piping, in accordance with manufacturer and vessel specifications. Prior to recirculation through the engines, the

Contractor shall test the jacket water for chloride and nitrite concentrations in accordance with manufacturer recommendations in the presence of the Coast Guard Inspector. Submit a CFR.

3.8 Reinstallation. After completion of testing and all authorized repairs, if any, the Contractor shall reinstall each cooler (if previously removed). Where applicable, renew all zinc electrode plates, gaskets, and recessed hex-head bolts in accordance with the manufacturer's specifications. Apply a copper-based anti-seize compound on all bolts, and torque in accordance with manufacturer’s specifications.

3.9 Touch-up preservation. The Contractor shall prepare and coat all new and disturbed surfaces to match existing adjacent surfaces in accordance with SFLC Std Spec 6310, paragraph 3.1.13 (Touch-ups and minor coating repairs.)

3.10 Cleanliness requirement. The Contractor shall visually inspect and ensure that all cleaned surfaces are completely free of debris and surface contaminants. Submit a CFR.

CAUTION

Extreme caution must be taken to not exceed manufacturer’s recommended test pressure during hydrostatic testing.

15 (Rev-0)

3.11 Pressure test. After all authorized work is complete and prior to reconnecting the heat exchanger(s), the Contractor shall pressure test each heat exchanger to the manufacturer’s recommended test pressure in accordance with the applicable Coast Guard drawing listed under Section 2 (References). In the absence of a specified test pressure noted in the Coast Guard drawing, the Contractor shall pressure test each heat exchanger in accordance with paragraph C2.7 (Heat exchangers and fluid coolers) of SFLC Std Spec

5000. Ensure zero leakage from or permanent deformation of pressure-containing parts by repairing all leaks, deformations, and discrepancies. Submit a CFR.

3.12 Label plates. The Contractor shall attach an anodized aluminum test data plate to each heat exchanger using epoxy resin cement. Ensure that each plate is engraved with ¼-inch high letters, stating the following:

Test pressure.

Test date.

Testing facility.

NOTE

If the heat exchanger design makes mounting a test data plate impractical, the

Government reserves the right to request written documentation of the above-listed testing data in lieu of a test data plate, at no additional cost to the

Government.

3.13 Leak test. After reconnecting the heat exchanger(s) on the vessel (and post undocking, if applicable), the Contractor shall perform an operational test of the heat exchanger and associated system piping for one hour using the system fluid at normal operating pressure. Ensure zero visible leakage from or deformation of mechanical parts by repairing all leaks and discrepancies. Submit a CFR.

4. NOTES

4.1 Contractor furnished equipment. The following parts list is provided to assist the Contractor in identifying some of the parts that may be required to accomplish the work detailed above for each fin stabilizer heat exchanger. This list may not reflect the most recent part number changes by the manufacturer; and this list is not fully comprehensive of the parts required to accomplish this work item.

The Contractor shall verify all part numbers and quantities with the manufacturer, prior to ordering. The

Contractor is cautioned to verify the cost of all materials required to complete this work item prior to submitting a bid price.
