The requirements in this WI applies to all work under the scope of this contract, whether explicitly stated in all following work items or not, and to all other work subsequently authorized by changes, modifications, or extensions to the contract.

3.1.1 The Contractor must conform to all requirements specified in SFLC Std Spec 5550 and in the Fire Protection and Response work item, as applicable, during the performance of this availability.

3.1.1.1 Fire Safety Plan submission. The Contractor must submit a copy of the CFR 1915, Subpart P, Fire Safety Plan with the Contractor’s bid when work will be conducted in a Contractor–owned facility. Include any MOA(s) with local firefighting facilities.

3.1.1.2 Fire Plan submission. The Contractor must submit a copy of the developed availability specific fire plan, with the Contractor’s bid.

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 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.

3 (Rev-0)

• 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.)

NOTE

NAVSEA drawings listed will be available FOR INSPECTION ONLY from the Coast Guard Port Engineer post-award. SFLC will not redistribute NAVSEA documents.

Contractors can apply to NAVSEA headquarters directly for copies.

3.2 Contractor-provided fire watch personnel. The Contractor must provide fire watch personnel and equipment.

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:

4 (Rev-0)

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:

5 (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.

3.5.2 Test and procedures. The Contractor is required to promptly conduct tests and procedures for the purpose of assessing whether operations are in compliance with applicable Environmental Laws. Analytical work must be done by qualified laboratories; and where required by law, the laboratories must be certified.

3.5.3 Regulatory notifications. The Contractor is responsible for all regulatory notification requirements in accordance with Federal, State, and local regulations. In cases where the Coast Guard must also provide public notification, such as storm water permitting, the Contractor must coordinate with the Contracting Officer or COR, and if work is being performed at a USCG Facility, the local Facility Engineer, or Engineering Officer. The Contractor must submit copies of all regulatory notifications to the Contracting Officer and the local Facility Engineer or Engineering Officer prior to commencement of work activities. Regulatory notifications must be provided for including but not limited to demolition, renovation, National Pollutant Discharge Elimination System (NPDES) defined site work, and remediation of controlled substances such as asbestos, hazardous waste, and lead paint.

3.5.4 Environmental manager. The Contractor must appoint in writing an Environmental Manager for the project, who is responsible for coordinating Contractor compliance with Federal, State, local, and station environmental requirements. The Environmental Manager must ensure compliance with Hazardous Waste Program requirements, including hazardous waste handling, storage, manifesting, and disposal; implement the Contractors’ Environmental Management Plan; ensure that all environmental permits are obtained, maintained, and closed out;

ensure compliance with Storm Water Program Management requirements; ensure compliance with Hazardous Materials including storage, handling, and reporting requirements; as well as coordinate any remediation of regulated substances such as lead, asbestos, and polychlorinated biphenyl (PCB). This may be a collateral position; however the individual must be trained to accomplish the following duties; ensure waste segregation and storage compatibility requirements are met; inspect and manage Satellite Accumulation areas; ensure only authorized personnel add wastes to containers; ensure all Contractor personnel are trained in 40 CFR requirements and individual position requirements; coordinate removal of waste containers; and maintain the Environmental Records binder and required documentation, including environmental permits compliance and close-out.

3.5.5 HW disposal. Contractor must comply with SFLC Std Spec 0000 Appendix A, Requirements For Environmental Protection At Contractor Operated (Non USCG) Facilities for HW disposal.

3.6 Local Policy. The Contractor must refer to site (e.g., Base) Regulations and Instructions for details regarding local policies (e.g., crane services, parking, or facility usage).

3.1 General.

3.1.1 CIR. The Contractor must submit a CIR for the inspections listed in the following paragraph(s):

3.6. Submit all initial inspection reports.

3.1.2 Tech Rep. None.

3.1.3 Protective measures. The Contractor must furnish and install all protective measures in accordance with SFLC Std Spec 0000, paragraph 3.3.3 (Vessel component, space, and equipment protection).

3.1.4 Interferences. The Contractor must handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).

3.1.5 Refer to all references in Section 2 above.

3.2 Propeller inspections. The Contractor must perform the following to each designated propeller (i.e.

marked “YES” in Table 1 above, if marked “NO” then do not perform this work). These inspections may be performed without removing the propeller from the shaft.

3.2.1 Visual inspections. Clean the propeller to a bright metal finish. Visually inspect the propeller in its entirety to identify all discrepancies (e.g. bends, deformation, torn material, and/or missing material, out-of-tolerance discontinuities per ABS Part 7 Appendix Section 10 Table 1, etc.) and any other abnormality that may negatively affect operation.

3.2.2 3-dimensional (3-D) scans. Using a portable 3-dimensional coordinate measuring machine (CMM), accurate to within 0.001”, scan all visible hub and blade surfaces of the propeller. Then accomplish the following:

obtain all required propeller design dimensions needed to calculate all required ISO 484/2 Class I tolerances using the Government-furnished propeller CAD model.

calculate all Class I tolerances for each required dimension over 48 stations (equally spaced) per blade (refer to Sections 7a, 7b, 7c, 7d, 8, 9, 11, 12.2, 12.3, 13 in ISO 484-2). Pitch radii must be measured at 0.3 R, 0.4 R, 0.5 R, 0.6 R, 0.7 R, 0.8 R, 0.9 R, and 0.95 R.

generate a report that shows each Class I design dimension and the calculated Class I tolerance for each dimension indicate on the report each corresponding measured/calculated dimension from actual propeller, and indicate which dimensions are not in tolerance of Class I make a list of all noted discrepancies and recommended repairs.

provide colored “heat map” images of actual dimensions superimposed over the CAD model showing where each measurement deviates from the CAD model dimensions by color gradient.

3.2.2.1 Do not perform a 3-D scan on a propeller that has failed a visual inspection; perform the scan on the new Government-furnished propeller after it has been installed on the shaft.

3.2.2.2 If requested by the KO, submit evidence proving that at least one on-site technician has successfully operated the scanning equipment in at least one prior similar contract, and has prior experience performing all the scanning tasks specified herein.

3.2.3 Report CD. Submit all measured and calculated data, and all associated images, using one or more editable/unprotected compact discs (CD). Record on each CD the propeller serial number and inspection date. Send each CD to the following address within 2 weeks of completing the inspections:

United States Coast Guard SFLC-Patrol Boat Product Line ATTN: SES Chief 300 East Main Street Norfolk, VA 23510

3.3 Shaft Remove/Reinstall. The Contractor must perform the following to each designated shaft (i.e. if marked “YES” in Table 1 above, if marked “NO” then do not perform this work). If requested by the KO, submit evidence that at least one on-site technician has successfully performed alignment measurements using optical or laser systems in a prior contract.

3.3.1 Shaft inspections. Remove the shaft from the vessel, mount the shaft on a machine supported on precision roller assemblies at two points, each no more than 24 inches from their respective end of the shaft. Slowly spin the shaft for at least 2hrs to remove all non-permanent bend/set (elastic hysteresis).

Identify all discrepancies and determine if the shaft is satisfactory for reuse or if renewal is warranted (e.g. significantly bent, journals damaged, etc.). Support findings by taking complete shaft journal dimensions and propulsion shaft run-out readings via dial indicator survey at the small and large ends of each taper, at the fore and aft ends of each bearing position, at three equally spaced locations between the bearings, and at three equally spaced locations between the intermediate bearing and coupling taper.

Mark each station at the position of maximum run-out on the periphery of the shaft. Record all data on the form at the end of this work item. All shaft inspections and measurements must be taken in the presence of the COR or the COR’s designated Coast Guard inspector. Polish shaft(s) IAW CG drawing 154B WPC 243-201, General Note 8 while removed.

3.3.1.1 Coupling Bolts/Nuts. IAW CG Drawing 154BWPC 243-201, Main Propulsion Shaft A&D, General Note 25: Socket head coupling bolts must be renewed and or stripped, Magnetic Particle tested and recoated with geometric coating. Renew all nuts.

3.3.2 Bearing inspections. Visually inspect all stern tube bearings staves for all discrepancies (e.g.

excessive wear, unusual wear patterns, etc.). Staves with greater than 0.025” wear must be renewed.

3.3.3 Alignment survey. Minimize thermal effects by performing measurements late in the evening or before sunrise. Take all measurements and record all data described in the forms at the end of this work item. Using optical or laser methods, establish a reference line square to, and through the center of, the reduction gear output flange. Measure and record on the forms at the end of this work item the vertical and horizontal offset of the centers of the following components from the reference line, and identify and record all discrepancies and repair recommendations (if any):

Shaft seal flange (“ADAPTOR PL”)

Forward end of the FWD stern tube bearing/housing

Aft end of the FWD stern tube bearing/housing

Forward end of the Prop End stern tube bearing/housing

Aft end of the Prop End stern tube bearing/housing

3.4 Shaft seal overhaul. The Contractor must perform the following to each designated shaft seal (i.e.

marked “YES” in Table 1 above, if marked “NO” then do not perform this work). Clean and visually inspect all non-expendable shaft seal components to identify all discrepancies. Renew all expendable shaft seal components. If the shaft is designated for removal in Table 1 above then use Service Kit “B” H76214-6 (non-split), otherwise use Service Kit “C” H76214-8 (split). If requested by the KO, submit evidence that one or more on-site technicians has successfully overhauled, renewed, or repaired the shaft face seal, or a similar model of face seal manufactured by the same company in a prior contract, and further describe all knowledge, experience, and training contributing to being qualified to disassemble/reassemble the shaft face seal.

3.5 Stern-tube component maintenance. The Contractor must perform the following to each designated stern tube (i.e. marked “YES” in Table 1 above, if marked “NO” then do not perform this work). Remove the rope guard and all stern tube access covers. Remove all growth and fouling from all accessible stern tube and shaft areas prior to performing inspections. Visually inspect all exposed surfaces (e.g. shafts, shaft bearing staves, stern tube surfaces and coatings, etc.) to the greatest extent practicable for all discrepancies (e.g. damage, corrosion, excessive and/or abnormal wear, failed coatings, etc.). Stern-tube coatings and structural inspections must be performed in the presence of the COR or the COR’s designated Coast Guard inspector. Renew all stern tube zinc anodes; if not already present install 12 each additional zinc anodes as shown in paragraph 4.4 (Arr & Dets stern tube zinc anodes) below. Renew the propeller zinc plate and associated fasteners.

3.6 Submit all initial inspection reports. For all inspections performed above, Submit a CIR detailing all findings, all discrepancies noted, and describe recommended repairs that will correct those discrepancies, with supporting justification. If components are satisfactory and no further repairs are recommended (e.g.

no prop/shaft renewal or repair required, no stern-tube coatings repairs required, etc.) then indicate that in the report, with supporting justification. Pending inspection results, a Change Request may be released by the KO to perform repairs.

3.7 System Restoration. After completion of all inspections, maintenance, and KO authorized repairs, the Contractor must re-assemble all disassembled components and restoring the entire system to its normal operating condition in preparation for testing.

3.8 Operational tests – post repairs. During sea trials, the Contractor must demonstrate proper operation of both propeller shaft systems via sea trials throughout the entire range of running speeds and directions.
