3.2 Transducer renewal particulars. The Contractor shall accomplish the following tasks using Coast Guard Drawing FL-6713-201 for guidance:

3.2.1 Transducer removal. Disconnect and remove the existing fathometer transducer. Retain the mounting hardware for reinstallation. Dispose of the removed transducer.

NOTE

Do not discard any hull ring adapter(s). They are to be reused with the new transducer(s).

3.4 Post installation tests. After completion of work, the Contractor shall accomplish the following tasks, in the presence of the Coast Guard Inspector:

3.4.1 Preliminary leak test. If not waterborne, inspect and perform a water hose test of all affected boundaries in accordance with SFLC Std Spec 0740, Appendix C. If waterborne, slowly back off the emergency cover plate bolts and allow seawater to flood the transducer well. No leakage allowed. Submit a CFR.

3.4.2 Not waterborne. Replace the hull ring set screws with new Monel fasteners, coating the threads with anti-seize compound. Recess the set screws ⅛” and cover with beeswax tallow.

3.4.3 Waterborne. Using a diver, remove and retain the hull ring set screws. Install an emergency cover plate and gasket over the transducer to be renewed. If available, the vessel’s emergency cover plate may be used; otherwise a new cover plate shall be fabricated and turned over to the vessel at the completion of the work.

3.4.3.1 Slowly back off the fasteners that normally maintain the transducer pressure boundary to sea. Ensure that any leakage through the emergency cover plate pressure boundary is minor prior to proceeding with transducer removal.

3.4.3.2 Upon completion of work and preliminary leak testing, completely remove the emergency cover plate. Clean all vacated tapped holes of anti-seize compound and beeswax tallow. Chase all threads. Install new Monel set screws in each hull ring, coating the threads with anti-seize compound. Recess the set screws ⅛” and cover with beeswax tallow.

3. 5 Leak repairs. The Contractor shall observe each transducer for leaks during the vessel re-floating process (if drydocked) or emergency cover plate removal (if waterborne). Repair all leaks detected. Submit a CFR.

3.6 Operational test – post repairs. After completion of work, the Contractor shall thoroughly test and prove the transducer(s) to be in satisfactory operating condition. Submit a CFR.
