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:

General Requirements

1. SCOPE

1.1 Scope. This item describes the general requirements to be followed by the Contractor while conducting this availability.

2. APPLICABLE DOCUMENTS

Coast Guard Maintenance and Logistics Command Atlantic (MLCA), Standard Specification 0000_STD, 2006 Edition, General Requirements

Coast Guard Maintenance and Logistics Command Atlantic (MLCA) Standard Specification 0740_STD, 2004 Edition, Welding and Allied Processes

Coast Guard Commandant Instruction (COMDTINST) M10360.3 (series), Jun 2006, Coatings and Color Manual

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

Page 2 (Rev-5) encountered in this specification package, including referenced standard specifications and other referenced documents, it shall refer to “COTR”, explicitly.

3.5 Small boat storage particulars. 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 pierside storage cradle, for safely storing said boat.

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

• Be capable of safely supporting a boat weighing approximately 5100 pounds.

• Support the boat at the following locations:

o Along the full length of the flat portion of the keel.

o Forward and aft, in the locations similar to those provided by the shipboard davit cradle.

• Have the portions of the cradle directly contacting the hull or keel of the boat made from a homogeneous soft wood, such as Yellow Pine or Douglas Fir.

3.5.2 Boat protective cover. Provide a watertight cover with

raised wooden spreaders, to protect the small boat from nature, during the storage period.

3.5.3 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, if required.

4. QUALITY ASSURANCE

No additional requirements.

5. NOTES

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

http://www.uscg.mil/directives/cim.asp

5.2 QA inspection forms. QA inspection forms (QA-1 thru QA-5), required in Std Spec 0000_STD to be completed and submitted http://www.uscg.mil/directives/cim.asp

Page 3 (Rev-5) during preservation of “critical-coated surfaces”, are provided at the end of this item.

Page 4 (Rev-5)

QA-1: QUALITY ASSURANCE INSPECTION FORM - PRESERVATION CHECKLIST

CHECKPOINT 1 – COATING SYSTEM COMPLIANCE

Ensure all coatings are in compliance with COMDTINST M10360.3, Appendix C.

CHECKPOINT 2 - PAINT STORAGE

Ensure all coatings are kept at a temperature of 65 to 85°F at all times, unless otherwise specified by the coating manufacturer(s).

CHECKPOINT 3 - AMBIENT CONDITIONS

Ensure surface and surrounding temperatures are each between 50 and 90°F for water-based coatings, and 35 and 95°F for other coatings, unless otherwise specified by the coating manufacturer(s).

Ensure maximum relative humidity (RH) is as follows, from surface preparations through final curing of topcoat: 50% for tanks, voids, and vent plenum; and 85% for all other areas, unless otherwise specified by manufacturer(s).

Ensure surface temperature is at least 5°F above the dew point, unless otherwise specified by the coating manufacturer(s).

CHECKPOINT 4 - PRE-SURFACE PREPARATION

Remove surface contaminants (soluble salts, loose rust, mud, and marine growth) with low pressure fresh water wash down (maximum 5,000 psi). If oil and grease are present, perform solvent cleaning, as per SSPC SP-1.

CHECKPOINT 5 - SURFACE PREPARATION

Verify environmental conditions (see CHECKPOINT 3).

Ensure cleanliness of prepared surface is as per specification (i.e.: SSPC SP-12, SP-11, SP-10…).

Verify surface anchor profile (1.5-3.5 mils for abrasive-blasted steel surfaces; 1.0 mil (minimum) for power-tool cleaned surfaces; 1.0-1.5 mils for abrasive-blasted aluminum surfaces); and 1.5 –2.5 for surfaces to be coated w/single coat of inorganic zinc).

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).
