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.

NOTE

Electric equipment must be defined herein as equipment which is used to convert, control, or utilize electrical power, such as: switchboards, power panels, load centers, motor controllers, and bus transfer switches.

3.3 Equipment loading. The Contractor must perform the thermal imaging survey while the electrical distribution system is fully loaded and energized and only after the vessel’s equipment has been energized and under load for at least 30 minutes prior to the inspection.

NOTE

Coast Guard personnel will perform start up and operational test of all shipboard machinery and equipment requiring to be energized and running for thermal imaging inspections.

3.4 Operational test, initial. Prior to commencement of any work, the Contractor must witness Coast Guard personnel perform an initial operational test of all items or shipboard devices to be disturbed, used, repaired, or altered, to demonstrate existing operational condition. Submit a CFR.

WARNING

Take all necessary precautions to prevent injury due to electric shock and potential arc-flash. Only necessary personnel (contracted or Ship’s Force) must be present in the compartment while energized panels are open. Only authorized personnel, and no Coast Guard personnel, must break the plane of the arc flash boundary.

3.5 Thermal imaging inspections. Prior to opening an electrical enclosure, the Contractor shall establish an arc flash boundary of at least four (4) feet from the electrical plane of the equipment. Clearly mark and erect a barrier to prevent the access of unauthorized personnel. Establish visible safety boundary at all entrances to the space where work is being performed using red danger tape or signage. Maintain this safety boundary until all thermal inspections are completed and all electrical covers are reinstalled within the space.

21 (Rev-0)

3.6 Infrared thermal imaging system (IRTIS) equipment. The Contractor must use Infrared Thermal Image System (IRTIS) equipment/camera in performance of this survey that meets or exceeds the following performance criteria:

Accuracy: +/- 1.5% or 1.5°C (2.7°F)

Object temperature range: 4 to +380°C (40 to +716°F)

Display Type: Color

Digital Image Type: Color and Grayscale

Color Palettes: Hot Iron, Rainbow, Grayscale

3.7 Test equipment calibration and operational checks. The Contractor must ensure the IRTIS equipment is calibrated and certified per manufacturer. The IRTIS equipment must be adjusted each time equipment is energized. Initially and when the IRTIS test equipment is operated continuously for long periods of time, a grey scale check must be made in accordance with the IRTIS manufacturer’s instructions.

3.8 Operator thermal imaging certification. Possession of a current ANSI/ASNT LEVEL I certification (or higher) meeting SNT-TC-1A: Personnel Qualification and Certification in Nondestructive Testing criteria is preferred. Otherwise, the Contractor shall describe all relevant thermal imaging skills and experience, as directed elsewhere in the solicitation.

3.9 Scan procedure. The Contractor must perform detailed thermal imaging scan of all wiring, connections, bus work and all current carrying components that are accessible without breaking the electrical plane of the electrical equipment being surveyed while observing the monitor for hot or cold spots. When a potential hot or cold spot is found, the contractor must determine the temperature difference between the hot or cold spot and surrounding equipment reference temperature.

NOTE

Fahrenheit (F) = Celsius (C)*(9/5) + 32, and C = (5/9)*(F-32)

Hot spot: A hot spot is a relative temperature related to the equipment which is surveyed. A general rule of thumb considers a ‘hot spot’ 18°F / 10°C or more above the equipment reference temperature.

Cold spot: A cold spot is any area of the equipment which is surveyed where the temperature is satisfactory, but exhibits an open connection, component fault, or some other similar problem.

3.9.1 Scan spot criteria. When detecting a hot or cold spot the Contractor must determine the temperature difference between the hot and cold spot in accordance with the IR test equipment OEM procedures manual. For a temperature difference of 70 degrees Celsius and above (Severity Code IV), imminent failure is expected, and must be reported immediately to the ship’s Engineering Officer and Contracting Officers Representative (COR.) Contractor must follow all criteria and all reporting actions on Table 2 excluding making repairs.
