3.1.1.3 SFLC-PBPL Availabilities (87 WPB, 110 WPB, & 154 WPC). The Contractor must conform to SFLC Std Spec 5550 with the following amendments and supplements:
• For contracts executed at a contractor’s facility, submit (pre-award) the facility’s Fire Safety Plan document described in 29 CFR 1915.502 – “Fire Safety Plan”. For planning assume that Coast Guard personnel will not be available to fight a fire.
• For all contracts at all facilities, submit the following information pre-award, taking into consideration how the maintenance/repairs specified in the work items will affect uninterrupted operation of the subject systems; make all necessary amendments to this submission after discussions with the COR at the arrival conference and during contract execution as emerging conditions warrant:
o Describe all anticipated needs for fire detection/alarm, fire-fighting, and shipboard lighting and communication systems supplementation (see below) and a description of the proposed remedies/solutions (include pricing for maintaining capability in pre-award quote).
o Describe how any required temporary/supplemental fire detection/alarm systems will notify fire responders.
o Describe all anticipated breaches of the cutter’s Fire Protection Boundaries and the proposed temporary solutions that will minimize impact on the Fire Protection Boundary’s proper function (e.g. removal of cables/hoses/etc. at the end of work day or installation of quick disconnects, installation of temporary fire curtains, etc.).
• Whenever maintenance/repairs described in work items or Change Requests necessitate securing, or making inoperable, all or part of the vessel’s fire detection or fire alarm system, submit a proposal to the COR/KO describing an equivalent method(s) for temporarily maintaining all lost functionality of the system(s). Select the
3 (Rev-0) most economical option(s) available (i.e. for extended loss of service of the entire system the temporary fire detections/alarm system described in SFLC Std Spec 5550 may be the best option, for shorter durations temporary watch standers may be more economical, etc.). After the COR has agreed to the proposal, maintain the capability of these systems for the duration of the contract to the greatest practicable extent.
• Whenever maintenance/repairs described in work items or Change Requests necessitate securing, or making inoperable, all or part of the vessel’s firefighting (e.g. fire main system, P100 and other dewatering systems, halon systems, portable fire extinguishers, etc.), lighting, and communications systems, submit a proposal to the COR/KO describing equivalent method(s) for temporarily maintaining all lost functionality of the system(s). Select the most economical option(s) available. After the COR has agreed to the proposal, maintain fire detection/alarm/fighting and lighting/communications capability for the duration of the contract to the greatest practicable extent.
• All Fire Protection Boundaries must be left intact and functional at all times to the greatest practicable extent. Notify the COR in writing whenever a breached Fire Protection Boundary will be left unattended outside of normal working hours (e.g. a door/hatch is made un-closable/un-securable due to repair work, an access cut is made into deck/bhd that is part of a Fire Protection Boundary, etc.). When a Fire Protection Boundary must be breached to facilitate contract work, minimize the impact using industry-standard methods (e.g. fire curtains, quick-disconnect fittings, etc.)
3.2 Fire watch requirements. The Contractor must refer to 3.3.1.3 (Fire watch requirements) of SFLC Std Spec 0000, in accomplishing the following task:
Provide portable fire extinguishers for Coast Guard fire watch personnel. Coast Guard fire watch is in lieu of contractor personnel during the hours of 0800-1600, Monday through Friday, and limited to two Coast Guard fire watch personnel.
Provide fire watch personnel and fire extinguishers for the duration of the availability period, during and beyond noted Coast Guard fire watch support.
3.3 Preservation requirements. The Contractor must accomplish all preservation tasks, including touch-ups, in accordance with SFLC Std Spec 6310.
3.3.1 Brand name approval. Ensure that all contractor-furnished coatings are in accordance with SFLC Std Spec 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.
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.
4 (Rev-0)
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.

17 (Rev-0)
Describe how RG feet will be removed and reinstalled onto rails, and how Chockfast liners will reinstalled. Describe what types of alignment jigs, instruments, and tools will be used (e.g. laser, dial indicator, strain gauge, etc.)
An “Operational Test Plan” containing an outline of all of the procedural steps required to fully prove a satisfactory install of the new RG.
A “Preservation Plan for F-Condition RG” that outlines the steps that will be taken to package, preserve, and seal-off the removed RG.
3.1.6 Operational test - initial. Prior to commencement of work, witness Coast Guard personnel perform an operational pre-test of all items and shipboard devices to be disturbed, used, repaired, or altered, to demonstrate existing operational condition. Inspect engine room bilge areas to determine extent of failed coatings. Prior to renewals submit a CFR that details any required growth repairs identified during the operational test based on the observed condition of the systems.
3.1.7 Inspection/Verification Sign-off Sheet. The Contractor must print off and maintain the sign-off sheet shown beneath paragraph 4.1 titled “FRC Reduction Gear Change Out Inspection/Verification Form” (or create and maintain an equivalent sheet). Immediately after completion of the predecessor task notify the COR/PE of the pending inspection, show and describe to the COR/PE the items requiring inspection and approval, then pending satisfactory inspection by the COR/PE, have the COR/PE sign the sheet to certify satisfactory completion of the task. Proceed with follow-on tasks only after receiving COR/PE witness, approval, and signature. Submit the filled-out sign-off sheet with the final testing CFR (described beneath paragraph 3.2.8) as certification that a Government representative was present for all listed inspections.
3.2 RG Renewal Requirements. The Contractor must renew the RG by performing and abiding by the following. Refer to TP-8903, Chapter 2 and Chapter 14 for Shipboard Removal and Installation Requirements.
NOTE
Ship’s Force will perform electrical isolation, tag-out procedures, etc.
Coordinate with Ship’s Force and ensure all of this work is complete prior to performing any maintenance.
3.2.1 Conduct preliminary inspections and tests. Conduct the preliminary tests specified in TP-8903, Chapter 2.
3.2.2 Remove interferences and prepare for rigging evolution. While removing all interferences, and in conjunction with RG removal/reinstallation, perform the following.
3.2.2.1 General. Take all necessary precautions to prevent all environmental elements (e.g. rain, birds, dirt, etc.) from entering the skin of the cutter while the WERP deck plates are removed. This may involve temporary installation of cofferdams around accesses openings, tents/shelters, etc. or other equivalent methods.
3.2.2.2 Maintain cutter stability parameters. Throughout the entire contract 1) maintain, at a minimum, lightship stability conditions, and 2) maintain a list small enough to allow direct vertical rigging of RG out of the ship with no need to apply a significant horizontal force to guide the RG in/out (e.g.
pulling/guiding with tag lines, pushing RG, etc), refer to TP-8903, Chapter 2. This will involve
18 (Rev-0) installation and adjustment of shoring and weights, or an equivalent method. Main deck loading must not exceed 1000 lbs per sqft.
3.2.2.3 WERP removal and reinstallation requirements. Maintain the dimensions of the clear opening created after WERPs are removed by install temporary structural members that will prevent all deformation of the superstructure that may occur after removing WERP plates in accordance with the approved “Removal and Reinstallation Plan” (NOTE: Post WERP removal expansion of the clear opening has been noted in the past and must be prevented.). Coordinate with the COR/PE 24 hours in advance of inspection of the installed temporary structural members and prior to removal of any WERP plate weld joint material, proceed with WERP removal after satisfactory COR/PE inspection of temporary structure. Minimize damage to WERP plate and surrounding structure by only removing existing weld joint material that attaches the WERP plate to the 01 LVL Deck. First saw/grind down into the weld joint approximately 1/8”, then carefully sever the remaining weld (approx 1/16”) using a chisel or equivalent method/tool to release the WERP plate from the 01 LVL Deck. Inspect WERP foundation bar for any damage that will require repairs before final WERP installation. Submit CFR. At reinstallation employ control welding to the greatest practicable extent to ensure no latent defects (e.g. cracks, warping, etc. at a later date).
3.2.3 Prepare installed intake/exhaust ducts and RG for removal. Prior to disturbing engine intake and exhaust ducts, secure (i.e. “cage”) all spring-loaded expansion joints (e.g. clamp together with turn buckles, etc. or equivalent method) to prevent release from their pre-disassembly dimensions/adjustment and label their locations. Measure and record all exhaust hanger distances prior to disassembly to aid in efficient reassembly and exhaust alignment.
3.2.4 Inspect engine intake ducts and exhaust ducts. Coordinate with the COR/PE 24 hours in advance of the inspection. In the presence of the COR/PE, wipe-down and visually inspect all accessible interior surfaces of all intake and exhaust piping and mufflers. Inspect soot trap. Determine if further disassembly and cleaning is required. Submit a CFR describing findings and any recommended additional cleaning.
3.2.5 Remove old RG, install new RG. Perform the following.
3.2.5.1 Record existing engine flange to RG flange alignment readings. Coordinate with the COR/PE 24 hours in advance of the inspection, and after removing engine to RG coupling and obtaining alignment instrument readings, show those instrument readings to the COR/PE. Submit CFR.
