Specification Feedback

The intent of this section is to inform all users that a spec feedback mechanism is in place, and is located on the MLCA Naval Engineering Division’s website. Spec feedback is a very important part of our overall continuous improvement process, and is crucial to specification development. It will allow spec writers to capture all specification-related lessons learned, and avoid mistakes or ambiguities in follow-on availabilities. All feedback will be reviewed, evaluated, and responded to in a timely manner.

If you have access to the CGWeb (Intranet), please use the following link, which will connect you to the MLCA(v) Naval Engineering website, for submitting your feedbacks:

http://webapps.mlca.uscg.mil/vdiv/specifications/feedback/default.cfm

If you do not have access to the CGWeb (Intranet), you may still submit your feedbacks, using the following web link:

3. REQUIREMENTS

3.1 General. The Contractor shall conform to all requirements specified in Std Spec 0000_STD and in this item, as applicable, during the performance of this availability.

NOTICE!

The requirements of paragraph 3.1 (General) applies to all work under the scope of this contract, whether explicitly stated in work items or not, and also to all other work subsequently authorized by changes, modifications, or extensions to the contract.

3.2 Contractor-provided fire watch personnel. The Contractor shall provide fire watch personnel and equipment.

3.3 Welding and brazing requirements. The Contractor shall perform all welding and allied processes, and nondestructive inspection (NDI), in accordance with Std Spec 0740_STD.

3.4 Term substitution - COTR for COR. The Contractor shall be aware that the term "COR" (Contracting Officer's Representative) has been discontinued in favor of "COTR" (Contracting Officer's Technical Representative); consequently, whenever "COR" is encountered in this specification package, including referenced standard specifications and other referenced documents, it shall refer to "COTR", explicitly.

Page 1 (Rev-1)

3.5 Small boat storage. When a small boat (Motor Surf Boat (MSB)/Motor Cargo Boat (MCB)/Rigid Hull Inflatable (RHI) boat) is removed as interference to Contractor-work, the Contractor shall provide a suitable pier side storage cradle, for safely storing said boat.

3.5.1 Cradle design. Ensure that the temporary cradle meets the following criteria:

• Structure is templated from the geometry and arrangement of the contact support areas of the existing cradle onboard the vessel, to provide same or more support area as that which is provided by the existing cradle.

• Arrangement will allow ship’s force to perform maintenance on the small boat, without modification of the cradle.

• Structure is manufactured using the most economical methods and materials available, and is capable of supporting the full weight of the small boat under normal conditions experienced during routine maintenance.

• Contact surfaces are no harder or rougher than the contact surfaces for existing cradle onboard the vessel.

3.5.2 Boat accessibility. Ensure the storage is located in the vicinity of the vessel, and is unrestricted, to allow for ship's force to complete maintenance during normal working hours for the entire performance period.

3.5.3 Boat protection. Provide full protection that can be safely and completely secured when the small boat is left unattended (e.g. watertight cover, storage in a warehouse or shop, etc.), in addition to isolating the boat from the elements.

3.5.4 Boat transportation. Transport each small boat to its storage area within one week of docking the vessel and back to the vessel prior to the end of the performance period.

4. NOTES

4.1 Access to COMDTINST M10360.3. The COMDTINST M10360.3 may be accessed at the following URL address:

Measure soluble salt conductivity (5 measurements per 1000 sqft) - maximum threshold: 70 microsiemens/cm for non-submerged surfaces and 30 microsiemens/cm for submerged surfaces.

CHECKPOINT 6 - PRIMER COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Verify proper mixing and stand-in (induction) times.

Ensure no paint is applied when the temperature is expected to drop to freezing before the paint has dried.

Ensure surfaces are completely dry, unless otherwise allowed by the Coating Manufacturer(s).

Verify wet film thickness at random, to prevent under or over application.

Brush out all runs, sags, drips, and puddles.

Perform visual inspection for holidays and other defects.

CHECKPOINT 7 - STRIPE COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer's instructions.

After primer coat (mist coat after inorganic zinc), brush-apply un-thinned coat of same primer paint over edges, weld seams, cut-outs, and areas of complex geometries @ 3-4 mils wet film thickness (WFT).

CHECKPOINT 8 - TOP COAT APPLICATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure overcoating window is as per manufacturer's instructions.

Verify proper mixing and stand-in (induction) times, as applicable.

Verify wet film thickness at random, to prevent under or over application.

CHECKPOINT 9 - FINAL INSPECTION

Verify final system dry film thickness.

Verify system cure for service resumption - U/W Body surfaces: 5-8 hours @ 77 degrees F; Potable water tanks: 7 days @

77 degrees F.

Ensure potable water tank exhaust ventilation is maintained continuously from and during coating application through final system cure (minimum 7 days @ 77 degrees F.), to exhaust all solvent to the atmosphere and to prevent solvent entrapment.

3.2 Pre-straightening inspection. Prior to initiating straightening processes, determine the location, magnitude and type of bend in the shaft, with the entire shaft supported on centers in a lathe, as follows:

• Before taking shaft runout readings, spin the shaft on the lathe for approximately two hours to eliminate any sagging that may have occurred during handling and storage.

• Conduct a dial indicator survey of shaft runout at stations spaced every two feet of shaft length to determine the magnitude and location of the bend.

• At each station, mark the position of maximum runout on the periphery of the shaft.

Page 22 (Rev-1)

NOTICE!

Be aware that the marks on the shaft periphery will be in a straight line if the shaft contains a simple bend, and will spiral part way around the shaft, if the shaft is both bent and twisted.

• Plot the maximum runout to an exaggerated scale, in order to locate the center of the bend, and to determine the extent of straightening required.

• Submit a CFR including locations and magnitudes of the bend.

3.3 Straightening procedures. Straighten the shaft to equal or less than 0.005" total indicator runout, using the localized heating (hot spotting method for carbon steel shafts, in accordance with MIL-STD- 2191, Section 11.2.2.2 and sub-paragraphs).

3.4 Post-straightening inspections. After completion of straightening procedures, accomplish inspections, and submit a CFR:

• Conduct non-destructive inspection of all straightened areas in accordance with Std Spec 0740_STD, Appendix C.

• Recheck the shaft surfaces, as specified in paragraph 3.2 (Pre-straightening inspection).
