3.1.1 Upon completion of the work, contact SHIPSUPT and ensure that each temporary cofferdam has been cleared by Diver.

3.2 Accomplish the requirements of ENCLOSURE (T) for cleaning of each ballast tank listed in 1.3.1 using 2.2 and 2.3 for guidance.

3.3 Accomplish an air test of existing piping listed in 1.3.2 to verify tightness of existing piping listed in 1.3.2, using clean air at 50 (+1/-0) PSIG for a minimum of 30 minutes, using 2.4 and 2.5 for guidance. Allowable leakage: None.

(V) "REPORT"

3.3.1 Submit one legible condition report listing results of the requirements of 3.3 to SUPERVISOR.

3.4 Accomplish the requirements of 009-032 of 2.1 for cleaning and preservation of each new and disturbed surface to match surrounding areas.

4. NOTES:

4.1 Initial Condition - During ships recent AMW CERT, Ships force discovered multicable penetration to be degraded causing sea water from the ballast tank to leak by into the space. When ships force attempted to pressurize the tank to remove sea water the assembly came out completely making the tank OOC. Tank is heavily relied upon for ballast and DEBALLASTING evolutions and is crucial to ships mission.

4.2 SRF tool room will issue each torque wrench and pressure gauge when required.

4.3 Each Cofferdam will be installed and removed by ICN 38KFA12321 H0l for the ballast tank.

4.4 Degaussing coil removal and installation work will be conducted under

38KFA12321 H02.
