3. REQUIREMENTS

3.1 General. The Contractor shall provide storage for the GFP when not in use, and safe handling when in use.

3.1.1 Storage. The storage area shall at a minimum be closed on all sides, dry, and locked when unattended.

3.1.2 Tech Rep. Not applicable.

3.2 Inspection. The Contractor shall carefully remove the fin stabilizer from the GFP wooden box and conduct a thorough inspection. A Condition Found Report (CFR) shall be submitted to the Coast Guard Contracting Officer (KO) within ten (10) days of receipt of GFP. The CFR shall include all inspection findings, test results as specified below, including any recommended repairs to return the fin stabilizer to serviceable “A” condition including repairs to or replacement of the wooden box. The CFR shall also include a breakdown of estimated cost of labor and materials for any repair work that is beyond the scope of work in this specification. No further work shall proceed until authorized by the KO.

NOTE

Serviceable “A” condition is defined as a reconditioned rudder meeting all required design specifications and design dimensions in accordance with Coast Guard drawing: 110C-WPB-565-001 and being capable of functioning and performing in the same manner as an identical new fin stabilizer although it may not have the appearance of a new fin stabilizer.

3.2.1 Visual inspection. While using Coast Guard drawing 110C WPB-565-001 and paragraph 3.4.2 of this requirement as guidance visually inspect the fin stabilizer for the following:

· Excessive wear on the stock bearing journal surfaces

· Straightness of stock and blade

· Key and Keyway excessive wear

· Any worn or damaged threats

· Corrosion and other mechanical defects

3.2.2 Paint removal. Abrasive grit blast all coated fin stabilizer surfaces to SSPC-SP 10/NACE No. 2 using grit conforming to MIL-A-22262 with a 3.0-4.0 mil profile. All pipe plugs shall be installed prior to grit blasting.

3.2.3 Ultrasonic test. Perform ultrasonic testing to the fin stabilizer to measure blade plate thickness. Take 20-30 UT shots on each side and log readings and location on CFR. Degradation in excess of 25% will render the fin stabilizer non-repairable.

3.2.4 Air pressure test. The Contractor shall conduct an air pressure test on the blade section after all the paint and primer are removed per section 3.2.2. Using a calibrated pressure gauge, test shall be performed at 1-1/2 PSI for a period of 30 minutes. If any pressure loss is noted, check porosity areas, plug threads, and all welds using a soapy water solution to expose leaky areas. The active formation of air bubbles on the blade surface indicates the presence of cavitation erosion damage. This condition needs to be repaired prior to acceptance. A second air test will need to be performed in order to ensure the void does not leak. All traces of soapy water solution shall be removed.

3.2.5 Fin stabilizer disposition. The Contractor shall secure, repackage and return any fin stabilizer the KO deems not repairable to the Coast Guard at the address listed in 5.7.1 unless otherwise directed. The wooden box shall be marked “H” condition as described in 5.5.2.

3.3 Welding certifications. The Contractor shall have welders qualified in accordance with Qualifications Standard for Welding and Brazing, and Welding and Brazing Operators per SFLC STD Spec 0740. Certification documentation shall be maintained and available to the KO, Contracting Officer’s Representative (COR) or Quality Assurance (QA) for review at any time during the contract period.

3.4 Fin stabilizer repairs. The Contractor shall:

3.4.1 Stock repair. Starting at the top of the 1” radius where the stock meets the fin stabilizer blade, machine to undercut the stock diameter ¼”. Clad weld buildup ¼” with 309 stainless steel material. Undercut the 309 stainless steel clad weld 1/8” below the nominal shaft diameter and clad weld back up with 308 stainless steel material to facilitate finish machining IAW drawing 110C WPB-565-001 (Sheet 5 of 8). The surface finish indicated on the drawing shall be in accordance with SAE J 448-2011 Standard. Polish all machined surfaces to a 32 RMS or smoother.

3.4.2 Length tolerance. The allowed length tolerance for each segment of stock diameter shall be +/- 1/64” (.0156”).

3.4.3 Non-Destructive Testing (NDI). The contractor shall perform Non-Destructive Testing as required by SFLC STD Spec 0740 for all welds.

3.5 Fin stabilizer blade coating and painting. The Contractor shall:

3.5.1 Flow coating (interior). The fin stabilizer internal cavity shall be filled and drained (flow coated) with corrosion preventative compound that conforms to MIL-PRF-16173 Grade 3. Replace pipe plugs with new stainless steel plugs in accordance with drawing 110C WPB 565-001 Rev. D Fin Stabilizer Details upon completion of flow coating. Flow coating of the internal fin stabilizer blade section shall be accomplished after all other repairs are complete.

3.5.2 Exterior painting. The Contractor shall:

3.5.2.1 Surface preparation. All fin stabilizers shall be cleaned and readied for painting as described below.

· Inspect the previously blasted surfaces to assure they still meet the SSPC-SP10 standard. If not, sandsweep or blast the surfaces again with abrasive grit to meet SSPC-SP 10/NACE No. 2 using grit conforming to MIL-A-22262 with a 3.0-4.0 mil profile. All pipe plugs shall be installed prior to grit blasting.

· Clean entire substrate surface free of chlorides and test until satisfactory results are achieved IAW SFLC Standard Spec 6310, section 3.1.8.5.

· Rewash and retest as needed until satisfactory results are achieved per SFLC Standard Spec 6310, section 3.1.8.5.

· Document chloride test results on paint report.

3.5.2.2 Painting/coating. The Contractor shall paint the fin stabilizer blade exterior surfaces by applying a high turbulence paint/coating system per SFLC Standard Specification 6310, Appendix C:

· The painting/coating system shall be applied with proper environmental, ventilation, humidity and temperature controls as specified by the pertinent OEM. The paint Contractor shall have a minimum of 5 years' experience dealing with the paint/coating application. Observe all the OEM safety precautions.

· Inspect blasted substrate, recording and keeping Testex tape readings in a project logbook. Apply two coats of high turbulence paint/coating (black), 10-11 mils dry film thickness each, to achieve a total of not less than 20 mils dry film thickness. Observe the curing time of recoating before application of the second coat.

3.5.2.3 Painting/coating of the exterior blade section shall be accomplished after all other repair work and interior flow coating is complete.

3.5.2.4 Paint data sheet. Paint data sheets shall be prepared to certify the paint type and mil thickness used on the fin stabilizer blade. The paint data sheet shall be packed with each overhauled fin stabilizer and a copy provided to the KO.

3.6 Final inspection and test report. A detailed Final Inspection and Test Report shall be submitted to the KO for approval prior to scheduling Coast Guard SFLC Quality Assurance personnel. The report shall depict the final condition of the fin stabilizer after all work has been completed. A copy of the inspection and test report shall be turned over to the Coast Guard Quality Assurance representative upon arrival for final inspection and testing. The inspection and test report shall contain the following information as a minimum:

· Contractor name, address and telephone number

· Contract number and delivery order number as applicable

· Fin stabilizer serial number(s)

· Written dimensional survey showing the fin stabilizer measurements and test results are within tolerance for each dimension shown on the drawing or per this requirement.

· Name of the person conducting the testing

4.5 Responsibility for compliance. All items shall meet the provisions of sections 3 & 5. The inspections set forth in this specification shall become part of the Contractor’s overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the government for acceptance comply with all requirements of the contract. Sampling for quality conformance does not authorize submission of known defective material (either indicated or actual) nor does it commit the government to acceptance of defective material.

4.6 Tests and inspections. The inspections/tests required here and in section 3.0 are the minimum required and are not intended to supplant any controls, examination, inspections or tests normally employed by the Contractor to assure the quality of the item in question.
