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/defaul t.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 Intent. This item describes the general requirements to be followed by the Contractor while conducting this availability.

1.2 Government-furnished property.

None.

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.

Page 2 (Rev-0)

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.

3.5 Small boat storage. When a small boat 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:

1. 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.

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

3. 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.

4. 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.

inspection.

20.7 Void inspection.

20.8 Zinc anode inspection.

3.4.2 The Contractor shall be aware that the Coast Guard

Underwater Hull Inspection Board (UWHIB) will recommend the extent of underwater body coating system preservation required, based on the conditions found during the underwater hull survey.

3.5 Hull cleaning - removal of marine growth. The Contractor

shall start cleaning the hull within four hours after the vessel has been lifted, to facilitate marine growth removal. Complete all cleaning operations within 24 hours after the vessel has been lifted.

Page 11 (Rev-0)

3.6.1 Temporary protective coverings. As soon as practicable

after drydocking and underwater body surface cleaning, install protective coverings, over zinc anodes, hull fairing materials, rudder bearings, stern tube and strut bearings, fin stabilizer seals, all exterior deck drains and all overboard discharges.

Wrap all bearings and seals immediately after the vessel is drydocked to prevent entry of debris, abrasives, and paint during cleaning, surface preparation, and painting. Insert soft caulking material into the open ends of rudder and shaft stave bearings to prevent entry of grit or other foreign material.

NOTICE!

Do not remove protective covers except for inspection or accomplishing specific work items.

3.6.2 Overboard discharge channeling and plugging. Place drain channels in overboard discharges in use to direct discharges away from the hull. Provide and install wooden plugs or coverings in sea chest spool pieces and overboard discharges not in use to prevent entry of sandblast grit or paint.

4. NOTES

4.1 Drydock terms. As used in these specifications, all

references to drydock facilities include graving drydocks, floating drydocks, marine railways, building ways or vertical lifts.

4.2 Arrival conditions. The Engineering Petty Officer (EPO)

will advise the Contractor of the actual tank and draft readings when the vessel arrives, and will discuss with the Contractor any ballast requirements necessary to accommodate the vessel draft and trim.

4.3 Paragraph number relationships. The paragraph number for

each subsection listed herein relates directly to identical sub-paragraph numbers in Std Spec 8634_STD.

4.4 Cutter Characteristics. The data shown does not represent the arrival displacement or docking displacement of the cutter.

4.5 Cradles. Many of the cradles used to dock the 110's were

built to the early drawing 085-002. The newer cradles have been built to 085-010. The drawings show minor variations in dimensions. It should be noted that while the Standard Spec calls for the cradle to be built just to 085-010, a cradle built to 085-002 is acceptable.
