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

3 (Rev-0) 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.)

In conjunction with, and incorporated into, the submission of the PD per paragraph 3.2.5 of SFLC Std Spec 0000, prepare and submit detailed removal and reinstallation plans that contain the following. After the final version of the PD is approved by the Coast Guard work may commence.

An “Interference Removal/Reinstallation and Access Cut Plan” containing a list of items that will be removed as interferences. Describe measures that will be taken to prevent contamination/water/etc. from entering the cutter, and measures that will ensure ship’s structure will not deform after removal of the WERP plates. Describe the control welding techniques that will be used to ensure the WERP plates and adjacent structure will not be warped or damaged, and that final weldment will not crack.

A “Cutter Stability Plan” containing a description of measures that will be taken to ensure the stability characteristics (described below in para 3.2.2.2 Maintain cutter stability parameters) are maintained.

16 (Rev-0)

A “Rigging Plan” containing type and rating of crane and a step-by-step description of the rigging evolution. Describe all lifting appliances (e.g. strong-backs, jigs, etc.) that will be used.

An “MRG Installation and Alignment Plan” containing a brief description of how the new MRG will be reconnected to all disturbed interfaces and how the new MRG will be aligned/connected to all hard-points (e.g. engine flange, main shaft, water ppg, etc.).

Describe how MRG feet will be removed and reinstalled onto rails, and how Chock-fast liners will be reinstalled. Describe what types of alignment jigs, instruments, and tools will be used (e.g. laser, dial indicator, etc.)

An “Operational Test Plan” containing an outline of all the procedural steps required to fully prove a satisfactory install of the new MRG.

A “Preservation Plan for F-Condition MRG” that outlines the steps that will be taken to package, preserve, and seal-off the removed MRG.

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 Main 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 MRG Renewal Requirements. The Contractor must renew the MRG by performing and abiding by the following. Refer to TP-8902A, Chapter 2 and Chapter 40 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.

Coordinate with Ship’s Force and the COR/PE to schedule pre-MRG removal sea trials for collecting preliminary test data on.

3.2.1 Conduct preliminary inspections and tests. Conduct the preliminary tests specified in TP-8902A, Chapter 2.

3.2.2 Remove interferences and prepare for rigging evolution. While removing all interferences, and in conjunction with R/G removal/reinstallation, perform the following.

17 (Rev-0)

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 MRG out of the ship with no need to apply a significant horizontal force to guide the MRG in/out (e.g.

pulling/guiding with tag lines, pushing MRG, etc), refer to TP-8902A, Chapter 2. This will involve 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 engines 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

18 (Rev-0) disassembly and cleaning is required. Submit a CFR describing findings and any recommended additional cleaning.

3.2.5 Remove old MRG, install new MRG. Perform the following.

3.2.5.1 Record existing engine flange to MRG flange alignment readings. Coordinate with the COR/PE 24 hours in advance of the inspection, and after removing engine to MRG coupling and obtaining alignment instrument readings, show those instrument readings to the COR/PE. Submit CFR.

NOTE

As of this writing, bilge coating condition does not warrant mandatory QP1 Certification or Independent NACE inspector. If, at the start of the contract performance period, bilge coating condition deteriorates past the thresholds specified in SFLC STD SPEC 6310 and SFLC STD SPEC 0000, these requirements will be invoked and additional associated preservation costs will be compensated by contract mod if necessary.

3.2.5.2 Clean and touch-up preserve bilges beneath MRG. Clean and pressure wash all engine room bilge surfaces to remove all loose contaminates and dirt. Submit a CFR describing the condition of bilge coatings and all discrepancies (e.g. failed coatings, rust, etc.), note all coating discrepancies in excess of 20 sqft total. Coordinate with the COR/PE 24 hours in advance of the inspection, and have the COR/PE inspect all preparation work prior to coating application. Touch-up preserve up to 10 sqft of failed or damaged bilge coating beneath the STBD RG and up to 10 sqft of failed or damaged bilge coating beneath the PORT MRG (i.e. include in pre-aMward quote), and apply one topcoat, up to 5mils, over all intact bilge surfaces. Additional coatings repairs will be authorized/funded by CR/mod to the contract.

See paragraph 3.2.11.1 below for coatings requirements.

3.2.5.3 Renewals. In addition to the Government-furnished MRG, renew the following components

All disturbed soft parts (e.g. seals, gaskets, o-rings, etc.).

All associated fluids (e.g. oil, grease, etc.)

All exhaust hanger rubber grommets.

Insulation Blankets covering the Exhaust Silencer only (do not renew blankets covering the exhaust pipe leading to and from the Exhaust Silencer, retain and reuse those blankets).

All disturbed hardware and fasteners (e.g. nuts, bolts, washers, studs, etc.).

All flex hoses and expansion joints leading to and from each affected RG.

The ASW expansion joint leading to the affected RG.

The ASW hose leading to each affected RG from the jacket water cooler.

All exhaust pipe gaskets.

3.2.5.4 Align engines to new reduction gearboxes. Align the engine output flanges to the MRG flanges in accordance with Coast Guard Drawing 154-WPC 085-201. Coordinate with the COR/PE 24 hours in advance of the inspection, and after completing the final alignment adjustments and obtaining satisfactory alignment instrument readings, show those instrument readings to the COR/PE. Submit CFR.

3.2.6 Repackage and ship removed MRG. Place the preserved F-condition MRG into the MRG container reusing the any protective foil bags from the “A” condition RG that may be present and accomplish the following:
