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 as requested in the Fire Protection and Response work item, 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:

Describe all anticipated needs for fire detection/alarm, fire-fighting, and shipboard lighting and communication systems supplementation (see bulleted paragraphs below) and a description of the proposed remedies/solutions (include pricing for maintaining capability in pre-award quote).

Prior to performing weld repairs (or potentially the entire availability), the Coast Guard will be securing and electrically isolating the installed fire alarm system, in conjunction with performing other measures that will protect installed electronic systems that could be damaged by weld repairs; therefore the vessel’s installed fire alarm/detection system will potentially not be available during the performance period. Provide a supplemental temporary fire-alarm system while the installed system is down. Monitor that system for the duration of its installation.

Describe how any required temporary/supplemental fire detection/alarm systems will notify fire responders.

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 workday 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.

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.

4 (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, Strenx 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 Strenx 900, all welding procedures and welder qualifications for welding Strenx 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 Strenx 900 are considered the same as those for welding HY-130.
