7.0 STATEMENT OF WORK REQUIRED:

7.1 Work Area Preparation:

7.1.1 Prior to start of work and with the assistance of Ship’s Force, conduct an operational test in the presence of the MSCREP of all flight deck aviation electronic and electrical gear, lighting, perimeter lights, recessed deck lights, flood and spot lights, including sprinklers, in the vicinity of flight deck areas identified for work, to demonstrate satisfactory operation. Document performance of test results noting “as-found” conditions. All deficiencies shall be submitted to the MSCREP for review.

7.1.2 Provide and erect all material and equipment to create a containment around the entire work area to ensure proper protection from weather and the environmental elements. Containment shall be properly ventilated to meet specifications required by paint manufacturer, and shall not vent into the skin of the ship.

7.1.3 Provide and erect all necessary staging required for proper working conditions and inspections.

7.1.4 Provide and maintain adequate lighting of a suitable nature during the course of all surface preparation, coating and inspection activities.

7.1.5 Remove, store and re-install all interferences as required to accomplish the work specified.

7.1.6 Temporarily install drop cloths, masking, division shields, seals, blanks and filtering materials to prevent abrasives and foreign substances from entering lights, machinery, piping, hatches, fork truck guards, deck drains, ventilation systems, tank vents, valve stems, motor shafts, seals and temporary openings during blasting and painting operations.

7.1.7 Prior to initiating surface preparation, the Contractor shall ensure the vessels equipment is protected from damage caused by blasting, water jetting, dirt, dust, paint or other foreign matter. Measures to be taken but are NOT limited to are:

a. Plug open ends of pipes, vents, and ducts. (vents shall not be plugged without Ship’s Force approval)

b. Wrap all valve stems and exposed portions of hydraulic cylinders. Install filters, if required, on all air intake vents. Install covers on all fuel tank vents.

c. In areas to be abrasive blasted or water-jetted and coated, record all ships markings, including information size and color.

d. Install protective coverings on all port-lights, windows, light globes and landing light lenses to prevent damage to inadvertent water-jetting or other means of non-skid removal.

e. Mask all normally unpainted surfaces.

f. Protect running rigging (cargo falls, lifts, cranes, etc.) and mooring lines which cannot be stowed or removed for the duration of non-skid removal.

g. Sprinklers shall be covered with sheet metal disks to prevent damage during surface preparation and coating.

h. Prove all deck drains on Flight Deck are free and clear in the presence of the MSCREP before non-skid removal.

7.1.8 Prior to the start of productive work, protective coverings shall be inspected and approved by the MSCREP.

a. Deficiencies noted during this inspection shall be corrected and the MSCREP shall be given the opportunity to inspect and approve the corrective measures before work begins. Protective covering shall be inspected at regular intervals, but not less than the start of each work shift. Degraded covering shall be repaired prior to restart of work.

7.1.9 Contamination of the vessel and its equipment shall be reported to the MSCREP verbally immediately upon discovery. The Contractor shall be responsible for cleaning the contaminated equipment and showing that the contamination has not caused damage. Cost to repair equipment damage due to contamination shall be the Contractor's responsibility. All cleaning and repairs shall be to the satisfaction of the MSCREP.

7.1.10 Prior to paint application, all helo tie downs shall be measured in accordance with NAVAIR requirements. A condition report shall be generated reporting the condition found.

b. If contamination is found, additional water wash shall be performed. Additional tests shall be made as necessary to determine the extent of contamination and to prove the success of remediation.

7.2.4 Vacuum blast the entire flight deck area including deck tie down fittings to a SSPC-SP-10 Near White Metal with a 2-4 mil surface profile.

7.2.5 Blasting material recovery shall meet the local pollution control district regulations.

b. All water jetted areas shall be prepared to a WJ-2 Condition. Non-visible surface cleanliness shall meet the definitions of NV-2 in Table A1.

c. No more than a light (L) grade flash rust shall be allowed on the steel at the time of coating application. If heavier flash rust is present, the surface shall be pressure washed at 2,500 to 3,000 PSI and allowed to air dry in order to restore the surface to a paint-able condition.

7.2.7 Open abrasive blasting will not be permitted.

7.2.8 Accomplish the requirements of SSPC-SP-11 Power Tool Clean to Bare Metal those areas inaccessible to the vacuum-blast machines and approximately 6 inches up all vertical surfaces of bulkheads, deck houses, foundations, fan housings, and other appendages in way of the aforementioned areas to bare metal. Ensure a minimum profile of 1 mil in way of power tool cleaned areas.

7.2.9 The hanger and truck tunnel door trough grating shall be removed from the ship and taken to the shop for grit blasting to white metal.

7.2.10 Regardless whether the surfaces are abrasive blasted or UHP Water Jetted, immediately prior to coating the surface shall be re-tested for non-visual surface contaminates at a rate of no less than one (1) test per 1,000 SF of prepared area.

a. The maximum allowable contamination concentrations for dry abrasive blasted surfaces shall be less than 10 ug/cm2 of chloride contaminants and less than 20 ug/cm2 of soluble sulfate contaminates as determined by field or laboratory analysis using reliable, reproducible test equipment. Results of this testing shall be presented to the MSCREP at the time of inspection for coating application. For UHP water jetted surfaces the requirements of Table A1, NV-2 shall apply.

b. If contamination is found, additional tests shall be made as necessary to determine the extent of contamination and to prove the success of re-mediation.
