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).

3.2 Inspection. The Contractor shall accompany the Underwater Hull Inspection Board (UWHIB) in the performance of the below inspection tasks, as applicable, using the drawings listed in Section 2 (References) as guidance. The Contractor shall provide the following, to facilitate the UWHIB in assessing the condition of the designated U/W hull components and systems:

• A hull repair supervisor and a marker.

• Temporary staging and other necessary equipment, as applicable, for ensuring safe access to all areas of the U/W hull.

NOTES

1. The COR will convene the UWHIB as soon as possible after the vessel has been dry-docked and before any work (except U/W hull cleaning/wash down) is performed on the U/W hull and appendages.

2. Some of the components and/or systems addressed in this work item may not be applicable to all vessel classes.

3.2.1 Hull plating. Inspect the condition of the hull plating (including thruster tunnel plating, as applicable), for the presence of marine growth, deformation, and any evidence of major corrosion or electrolytic action.

3.2.1.2 Inspect the hull and keel areas, report on the condition of butt-welded seams, doubler plates, lap seams, and for any signs of damaged plating or unusual waviness in the plating.

3.2.2 Sea chests and all other cooling system intake components. Inspect all sea chests, sea beam arrays, tunnels, hull openings, and grates for general appearance, loose, damaged, or missing grates, loose or missing fasteners, condition of sea strainers and lockwire on bolts, marine growth on grating slots, and any obstructions in the openings that might prevent proper suction and discharge of water.

3.2.3 Rudders. Check general condition, condition around the drain plugs, and check for pitting, if any, on the leading and trailing edges.

3.2.4 Propeller and shaft associated components. Inspect the condition of propellers for signs of corrosion, pitting, erosion, fouling, cracks, dings, and nicks by side and blade; inspect fairwaters, rope guards, shafts, and mechanical seals - look for missing screws, physical damage to the blades, pitting, condition of dunce caps, and condition of securing devices.

3.2.5 Transducers. Check general condition for cuts, cracks, corrosion, and surface defects around the

15 (Rev-0) openings. Check transducer securing nuts for tightness, and inspect cables for chafing and other damage.

3.2.6 Zinc anodes. Remove all marine growth and oxide coating from all hull, rudder, shaft strut, sea chest, sea beam array, z-drive, and thruster tunnel zinc anodes, or water jet drives anodes, as applicable, using a light-wire brush.

3.2.6.1 Visually inspect all zinc anodes; check the soundness of mounting strap and stud welds, missing fasteners, and percentage of remaining material.

3.2.7 Coating system inspections. Accomplish the below inspections, in conjunction with the underwater hull inspection conducted by the Underwater Hull Inspection Board (UWHIB). Document the condition found as “Partial - Condition A”, “Partial - Condition B”, “Partial Condition C”, or “100%”, as applicable (see 4.1 (Definitions)). Submit a CFR.

NOTE

The following inspections are for determining the existing condition of the coating system for the underwater body surfaces, which are deemed “Critical-coated” surfaces; they must be carried out by a SSPC-QP-1 certified contractor/sub-Contractor or a NACE Inspector – see SFLC Std Spec 0000, paragraph 3.2.4.2 (In-process QC measures for “critical-coated surfaces”).

3.2.7.1 Visual. Perform a visual inspection of the existing U/W body coating system.

3.2.7.2 Dry film thickness (DFT) measurements. Take total DFT measurements of the U/W body coating system, in accordance with SSPC-PA 2.

3.2.7.3 Coating system thickness and scheme inspection. Perform a microscopic observation of precision angular cuts in the coating system film (“Tooke Paint Inspection”), in accordance with ASTM D4138, and measure the total coating thickness and thickness of each individual coat of paint, in addition to identifying/verifying the existing color scheme for each coat of paint comprising the coating system.

NOTE

The Tooke Paint Inspection Gage/Gauge (Plastic) is a precision tool for inspection and thickness measurement (ASTM D4138) of single or multiple coats on any substrate, and for microscopic observation and measurement of substrate and film defects. The gage uses an illuminated 50-power microscope with measuring reticle, and mounts tungsten carbide cutting tips for precise incision of the work surface.

Direct measurement of total coating thickness and thickness of individual coats of paint is a unique capability of the Tooke Paint Inspection Gage/Gauge. Thus, in addition to routine use, it often serves as a “referee” instrument to calibrate indirect or non-destructive thickness measuring instruments.

Other uses include assessment of substrate conditions and coating adhesion, and observation of microscopic cracking, tendency for brittleness, cratering, or other microscopic film symptoms.

3.2.7.3.1 Take a total of four readings in locations designated by the Coast Guard Inspector, and as follows: one each, port and starboard, in the boot-top area; and one each, port and starboard, below the

16 (Rev-0) boot-topping.

3.2.7.3.2 Ensure that the repair of all areas affected by the destructive Tooke Gauge inspection is included in the optional repair work item that is activated by the result of the inspection.

4. NOTES

4.1 Definitions. 4.1.1 "Partial – Condition A”: The condition that exists where the substrate is exposed in up to 33% of the entire U/W body.

4.1.2 "Partial - Condition B": The condition that exists where the anticorrosive (AC) undercoating system has incurred damage, but, the u/w body hull substrate is not exposed in any location.

4.1.3 "Partial - Condition C”: The condition that exists where damage is confined to the antifoulant (AF) topcoating; the epoxy undercoating system is not exposed in any location.

4.1.4 "100%”: The condition that exists where more than 33% of the U/W body hull substrate is exposed.

4.2 UWHIB convention. The COR will convene the UWHIB as soon as possible after the vessel has been dry-docked and before any work (except U/W hull cleaning/wash down) is performed on the U/W hull and appendages.
