ABSTRACT

It is the intent of this ITEM to define the general requirements regarding all paint preparation and application of coatings as part of this contract.

LOCATION / DESCRIPTION Throughout ship.

NOTES Not Separately Priced (NSP) in Section B Pricing. See ITEM 119.

STATEMENT OF WORK

The Contractor shall provide all labor, materials and services to accomplish the intent of this ITEM. In addition, and at a minimum, the Contractor shall:

Provide all paint needed for this SOW.

Receive all paints from the paint vendor and with the knowledge of the COR or his designated person, have it inventoried, stored under cover, and its distribution controlled to eliminate waste or improper use.

Provide a Paint Manufacturer's Technical Representative to oversee the preparation and application of all paints/coatings needed for this SOW. All coatings shall be applied under the direct supervision of the Paint Manufacturer's Technical Representative. No application of coatings shall be made until the prepared surfaces are approved by the Paint Manufacturer's Technical Representative. The Contractor shall arrange for such inspections prior to the initial coating and prior to each subsequent coating.

Ensure that all paint shall be completely mixed; ensuring bottom sediments are in suspension. Thinning shall only be done in accordance with manufacturer's instructions.

Coverage and final thickness shall be specified by the paint manufacturer's representative.

Protect all structures and equipment not to be blasted which are in way of the blast pattern.

Protect depth sounder plates, hull anodes, propellers, tail-shaft and other vulnerable areas while the blasting operation is being carried out. Plug all deck scuppers and/or install temporary extension shields on the scuppers to the hull dry during blasting and coating operations.

Ensure that steel temperatures are a minimum of four (4) degrees Fahrenheit above the dew point of the air prior to the application of any coatings. COATINGS SHALL NOT BE

APPLIED WHEN CONDENSATION IS PRESENT ON THE SURFACE.

No application of coatings shall be made until the prepared surfaces temperatures are a minimum of thirty-five (35) degrees Fahrenheit and then only if within the specified temperature range of the paint manufactures product.

Take and record the final dry film thickness (DFT) readings. Log the preparation, coating system and quantities of the material used on each area of the hull. The paint manufacturer's representative shall fill out the coating portion of Maritime Administration Dry Docking Report (MA-57).

Ensure that any grit abrasive used for blasting shall be dry, have the proper pH, meet the requirements of the paint manufacturer's product data sheet and be acceptable to the on-site Paint Manufacturer's Technical Representative.

Ensure that all coatings are applied in accordance with the paint manufacturer's instructions. Every attempt should be made to minimize overspray. Areas found to contain runs; overspray, roughness or any other film irregularities shall be repaired or recoated as directed.

Ensure that the final dry film thickness (DFT) readings be taken and recorded using an ultrasonic thickness instrument. A detailed report outlining the preparation, coating system and quantities of material shall be provided to the COR and a copy retained on board in the Chief Mate's office.

Ensure that staging for painting shall be absolutely free from grit when any coating is being applied. Ensure that outdoor coatings shall be applied only under favorable weather conditions.

Ensure that freshly applied coatings are protected from blasting in adjacent areas.

Whenever there are multiple coats specified as part of the paint system each paint coat shall be of a contrasting color to the subsequent coats to ensure complete coverage at the required mil thickness.

Ensure that coatings do not take place when the relative humidity is above 85%. No coatings shall be applied to surfaces on which oxidation has commenced.

Ensure that all paint manufacturers’ drying and recoating times are strictly adhered to.

Ensure that when working localized areas or spots, removal of old paint shall extend beyond the edges of the spot until an area of completely intact and adherent paint film is present. The edges of the remaining tightly adherent paint around the area to be repainted shall be feathered down sufficiently to avoid a "patch work" effect. Overlap new paint over existing coating by at least 2 to 3 cm.

The Contractor shall include the cost for adherence to this ITEM within the individual ITEMs requiring surface preparation and coating.

PERFORMANCE CRITERIA / DELIVERABLES

The paint manufacturer's representative shall fill out the coating portion of Maritime Administration Dry Docking Report (MA-57).

A detailed report outlining the preparation, coating system and quantities of material shall be provided to the COR and a copy retained on board in the Chief Mate's office.
