3. REQUIREMENTS

3.1 General.

3.1.1 CIR.

11 (Rev-1)

None.

3.1.2 Tech Rep.

Not applicable.

3.1.3 Protective measures. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces near the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness.

3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences). Known interferences include, but are not limited to the following:

• Deck plate.

• Deck plate framing.

• Propulsion shaft.

3.2 Seal overhaul particulars. The Contractor shall accomplish the following for each shaft seal assembly, using TP-3495 as a guide:

• Disassemble and remove the shaft seal assembly and emergency shaft seal inflator system.

• Clean all components free of marine growth.

• Perform visual inspection of cleaned components. Submit CFR.

• Renew all seal components with Government-furnished shaft seal assembly kit and emergency shaft seal inflator.

• Renew shaft seal cooling flex hoses.

• Reassemble and reinstall the seal assembly.

CAUTION

Do not rotate shaft during overhaul tasks.

NOTE

The seal inflator adaptor is of universal length and will require adjustments.

3.2.1 The Contractor shall measure, cut, and fit the inflator adaptor to the length required to achieve a depth that passes into the center chamber of the inflator but not touch the inside wall of the interior diameter. The seal inflator adaptor end shall be rounded following the cutting to length, to prevent rubbing/chaffing. When installed and the seal inflation cycled, the seal must return to a fully relaxed position with no visible bulging or protrusion in the seal inflator adaptor area.

3.2.2 Prior to installing the mechanical shaft seal assembly on the cutter, the Contractor shall perform NDT testing of the newly installed shaft seal inflator. Install a 4-inch stub shaft into the emergency shaft seal of similar or better surface finish of the propulsion shaft. Inflate the emergency shaft seal inflator to a pressure of 15 psi to engage seal, maximum 40 psi. Visually inspect the seal to ensure that it inflates uniformly around the shaft and is not bulging or otherwise displaying signs of mechanical derangement or seal compromise. Leave the emergency shaft seal inflated with the stub shaft installed and submerge the

12 (Rev-1) system in water for 5-minutes. Inspect for signs of air leaks from the emergency shaft seal inflation tube or Schraeder valve assembly. Remove the emergency shaft seal inflator and stub shaft from the water and orient the inflator with the mounting flange facing up. Fill the cavity between the stub shaft and seal housing with water up to the mounting flange. After 5-minutes have elapsed, inspect the water level in the seal housing for signs of leakage. No visible air or water leaks are permitted. Make repairs as necessary to obtain a leak free condition. Submit a CFR.

3.2.3 After the propulsion shafts have been installed and coupled to the reduction gear output flanges, the Contractor shall perform a clearance measurement between the propulsion shaft and the shaft seal adapter flange thru the emergency inflator boss across the vertical and horizontal planes; make any adjustments necessary to re-center the seal around the shaft. Submit a CFR.

NOTE

Minor relocating of the shaft seal adapter flange within the mechanical limits of the pilot grooves is authorized to achieve the Duramax running clearance tolerances between the propulsion shaft to shaft seal adapter flange. It is IMPORTANT that upon installation of the Duramax Marine Shaft Seal System that the propeller shaft is as close to the center of the friction ring as possible. Failure to center the shaft could cause it to hit the inside of the friction ring. If this happens the seal faces could separate and drip.

3.3 Government right to change out seal assembly. The Contractor shall be aware that the Government reserves the right to furnish up to two new shaft seal assemblies in lieu of overhauling the seals, at no additional cost to the Government.

3.4 Seal venting. After launching the cutter and in the presence of the Coast Guard Inspector, the Contractor shall remove the cooling water injection lines from both seals and allow the stern tube and seal assemblies to flood with water, in accordance with the manufacturer’s guidance in TP 3495 and CG Drawing 110C WPB 161-005. When the air is vented from the seal assemblies re-connect the injection lines.

WARNING

Do not rotate shaft until the stern tubes have been vented.

3.5 Operational test, post repairs. After completion of work and in the presence of the Coast Guard Inspector, the Contractor shall thoroughly test and demonstrate the equipment listed below to be in satisfactory operating condition. Submit a CFR.

• Shaft seal assembly

NOTE

Pay special attention to water leaks, abnormal noises, and any binding in normal shaft operation.

3.6 Touch-up preservation. The Contractor shall prepare and coat all new and disturbed surfaces to match existing adjacent surfaces in accordance with SFLC Std Spec 6310, paragraph 3.1.13 (Touch-ups and minor coating repairs).
