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.

• 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 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 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.

3.5.2 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.

None.

15 (Rev-1)

3.1.2 Tech Rep.

Not applicable.

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, (Interferences). Known interferences include, but are not limited to the following:

• Deck plates

• Work bench

• Piping

• Engine room machinery

3.2 Removal. The Contractor must disconnect and remove the flexible connections between the main engine and the connected fluid systems for fuel, oil, lube oil, jacket water and seawater in accordance with the Coast Guard drawings and publications listed in Section 2 (References).

3.3 Alignment between coupling flanges. The Contractor must inspect each expansion joint piping flanges for axial, lateral, angular, and torsional alignment prior to installing new flexible connections and control rod assemblies, as follows. Submit a CFR.

NOTES

1. Piping misalignment in the system should not exceed a maximum of plus or minus 1/8 inch.

2. Axial alignment measurement should correspond to the expansion joint’s face to face dimension otherwise an axial misalignment is indicated.

3. Lateral misalignment is indicated by any variation in the measured dimensions and an inconsistency in the level.

4. Angular misalignment is indicated by any variation in the measured dimensions.

5. Torsional misalignment is indicated by any bolt holes on each flange not lining up to each other.

3.3.1 Axial alignment. Measure from inside of one mating flange to the inside of the other, to include the area in which the expansion joint is to be installed.

3.3.2 Lateral alignment. Place a level on the outside edge of the mating flanges and measure the distance across. Repeat the measurement an additional three times to obtain a total of four measurements evenly distributed around the circumference of the mating flanges.

3.3.3 Angular alignment. Measure from the edge of one mating flange to the same corresponding spot on the opposite flange. Record this value and then repeat the same measurement on the opposite side of the flange (180 degrees from the initial measurement). Repeat these measurements to obtain a total of at least four paired measurements evenly distributed around the circumference of the flanges.

16 (Rev-1)

3.3.4 Torsional alignment. Check the flange bolt pattern on each mating flange to ensure the bolt holes on each flange line up to each other.

3.4 Pipe hanger inspection. The Contractor must inspect the condition of each of the associated pipe hangers and other support devices in the vicinity of the flexible expansion joint being renewed, to ensure they are adequately supporting the weight of the piping systems and in accordance with MSS SP-58.

Significant movement of the piping system when the expansion joint is removed indicates the pipe hanger arrangement is insufficient. Submit a CFR.

3.5 Installation. The Contractor must install new flexible expansion joints, control rod assemblies, and Integral Tie Rod (ITR) plates after all alignment measurements have been verified to be within tolerance or corrected via a change request authorized by the KO, in accordance with Coast Guard Drawings and Tech Pubs listed in Section 2 (References). The Contractor must renew all grade eight fasteners, flat washers, lock washers and nuts.

3.5.1 ITR plate position. The Contractor must secure the ITR plates in place with the flange bolting.

Position the ITR plates as shown below. Install the flange bolt head and flat washer against the ITR plates.

3.5.2 Control rod assembly adjustment. The Contractor must ensure the following.

• Control rods are evenly spaced around the joint.

• Inner control rod nuts are adjusted to allow zero joint compression.

• Outer control rod nuts are adjusted to allow approximately 1/8 inch joint expansion.

NOTE

Coast Guard personnel will operate all shipboard machinery and equipment.

17 (Rev-1)

3.6 Operational test, post repairs. After completion of work, the Contractor must thoroughly test, in the presence of the Coast Guard Inspector and demonstrate all items or shipboard devices that have been disturbed, used, repaired, altered, or installed to be in satisfactory operating condition. Submit a CFR.
