3.0 REQUIREMENTS

3.1 Inspection and Estimate: Contractor shall carefully remove the fin stabilizer from the

GFP crate and conduct a preliminary inspection to determine estimated cost of labor and materials necessary to return the fin stabilizer to a serviceable “A” condition as described above. A Condition Found Report (CFR) and estimated breakdown of all labor, materials and costs required to overhaul, test, preserve, pack, package and mark each fin stabilizer including repair or replacement of the shipping container/skid shall be submitted to the

Coast Guard Contracting Officer (KO) within ten (10) days of receipt of GFP. No further work shall proceed until authorized by the Contracting Officer.

3.1.1 Paint Removal: Abrasive grit blast all coated fin 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.

3.1.2 Visually inspect the fin stock for the following:

a. Excessive wear on the stock bearing journal surfaces.

b. Straightness.

c. Key and Keyway defects.
