6310, Appendix C (Authorized Coatings for Use on Cutters and Boats).

3.3.2 Coating colors and system color schemes. The Contractor must obtain a written KO authorization to deviate from any coatings required in SFLC Std Spec 6310 Appendix C before work.

3.3.3 In-process quality control measures. The Contractor must abide by all the safety, preservation, and quality control requirements specified in SFLC Std Spec 0000, paragraph 3.2.4.2 (In-process QC measures for “critical-coated surfaces”).

3.3.3.1 Quality control requirements. The Contractor must abide by the following when performing preservation related inspections. The following measurements must be randomly spaced throughout for the purposes of providing a representation of the entire prepared or coated surface.

3.3.3.1.1 Surface profile measurements. One surface profile measurement must be taken for every 200 square feet for the first 1000 square feet; for each additional 500 square feet or less, one profile measurement must be taken.

3 (Rev-0)

Profile measurements must be taken in accordance with SFLC Std Spec 6310, paragraph 3.1.8.3 (Surface profile measurements). A “measurement” for surface profile is defined as follows:

• ASTM D4417, Method B: One profile measurement is the average (mean) of 10 individual readings.

• ASTM D4417, Method C: One profile measurement is the average (mean) of 2 individual readings.

3.3.3.1.2 Soluble salt conductivity measurements. 5 conductivity measurements must be taken every 1000 square feet. For submerged (immersed) applications conductivity measurements must not exceed 30 microsiemens/cm.

For non-submerged (non-immersed) applications conductivity measurements must not exceed 70 microsiemens/cm. If a conductivity check fails, clean the surface in accordance with SFLC Std Spec 6310, paragraph 3.1.8.5 (Soluble salt removal).

3.3.3.1.3 Coating thickness measurements. Three area measurements must be taken for the first 1000 square feet;

for each additional 1000 square feet, perform an additional area measurement. A “measurement” for coating thickness is defined as follows:

• SSPC-PA 2 defines an area measurement as 5 separate spot measurements randomly spaced throughout a 100 square foot area.

• SSPC-PA 2 defines a spot measurement as 3 gage readings and each new gage reading the probe must be moved to a new location within a 1.5-inch diameter circle defining the spot.

3.4 Welding and brazing requirements. The Contractor must perform all welding and allied processes, and NDE in accordance with SFLC Std Spec 0740.

3.4.1 HY-130 material substitution. The Contractor must be aware that HY-130 steel plating is no longer commercially available. For the purpose of performing flight deck repairs on US Coast Guard WMEC-270 “B-

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 must 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 evaluation (NDE) in accordance with

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

NOTE

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 are considered the same as those for welding HY-130.

3.5 Environmental protection requirements. The Contractor must adhere to the following environmental protection requirements in accordance with the SFLC Stand Spec 0000:

4 (Rev-0)

3.5.1 Contractor operated (non USCG) facilities. The Contractor must provide and maintain environmental protection as defined in SFLC Std Spec 0000 Appendix A, Requirements for Environmental Protection at

Contractor Operated (Non USCG) Facilities, as applicable, during the performance of this availability. Contractor must plan for and provide environmental protective measures to control pollution that develops during normal practice, as well as plan for and provide environmental protective measures required to correct conditions that develop during the project. Contractor must comply with applicable Federal, state, and local laws, codes, ordinances, and regulations in their entirety. Any reference to a specific portion of a Federal, state, or local law, code, ordinance, or regulation in this or any other item must not be construed to mean that relief is provided from any other sections of the law, code, ordinance, or regulation.

3.5.1.1 USCG Generator status. The activity Generator Status for the Coast Guard Facility is small quantity conditionally exempt.

3.5.1.2 Plans and permits. The CG Facility has unit specific permits including the following:

3.2.7 All lifting equipment; chain blocks, rope, nylon slings, wire rope slings, and any other equipment must be washed clean prior to use to prevent dirt or paint chips from falling into the open reduction gear casing.

3.2.8 All disconnected lube oil piping must be blanked immediately after opening to prevent dirt or foreign particle intrusion.

3.2.8.1 Some MDE exhaust piping is removed for interference. Blank off the resulting opening that leads to turbocharger to prevent dirt or foreign particle intrusion into the turbocharger.

3.2.9 All parts must be thoroughly cleaned prior to reassembly of the reduction gear.

3.2.10 Observe and implement all the precautions detailed in CG Tech Pub 3253, for opening and protecting parts, equipment, and personnel. Note in particular the following:

3.2.10.1 Avoid damage to all joint surfaces. Prevent the forming of burrs or ridges that will result in oil leakage. Protect joint flanges with clean canvas and wooden blanks or sturdy plastic wrap.

3.2.10.2 Mark or tag parts to aid in correct reassembly. Place these parts in clean containers for temporary storage. Match mark parts as necessary where indexed relationships between parts exist for proper fit or operation of the equipment.

3.2.10.3 Treat thermometers and sight flow indicators, when removed, with care and blank exposed pipe and flange ends to prevent contamination. Sections of oil supply and drain piping should be removed from the-immediate area to prevent damage, bending or other casualty which may hinder proper reassembly.

3.2.10.4 Protect all pipe openings with clean, canvas covered tapered wooden plugs, caps , or bolted blanks. Do not use rags or waste for this application.

3.2.10.5 Covers, end covers and other portions of the housing, when removed, must be placed and supported to fully protect the flange joints. Support heavy parts on wooden blocks or inverted, whichever is easier and allows the better protection in the available space. Pinions and gears, if removed should be supported on clean wooden blocks and must be covered with clean canvas.

NOTE

Contractor may request to suspend some components from the overhead, either short term or long term. Those request (suspending parts) must be agreed to by USCG.
