List of Critical Inspection Items

The following is a list of work items, which contain Critical Inspection reports, which the Contractor must complete within the first 25% of the availability contract period (see Std Spec 0000_STD, paragraph 3.6.2 (Inspection report particulars)):

Work Item Title Perform Ultrasonic Thickness Measurements (D) Perform Ultrasonic Thickness Measurements (O) Inspect RHIB Notch Skid Pads (D) Remove, Inspect, and Reinstall Propeller Shafts (D) Renew Sea Valves and Inspect Associated Piping and Strainers (D) Remove, Inspect, and Reinstall Rudder Assemblies (D) Preserve Stern Tubes (O) Modify and Preserve the Forepeak (EC 087-A-033) 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.

WARNING!

Prior to performing welding, Ship’s Force will take precautions to isolate all electronic equipment installed on the cutter from welding current. Do not perform welding until proper isolation has been verified.

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.

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:

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.
