The high-pressure wash shall be performed with fresh water only and shall be no less than 5000 psi. All washing to be performed shall be done from above (i.e. from the top of the drydock, scaffolds, etc.) with the nozzles pointed down to the floor of the dock to prevent the spread of water to the upper portion of the vessel and into any interior spaces.
Any areas contaminated with grease, oil, dirt, rubber streaks or other foreign matter shall be cleaned with DEVOE “Dev-prep # 88”, 788 T-000 (or equal) and washed clear with the high-pressure wash.
After the Vessel hull has dried and within 24 hours after drydocking the vessel, a joint inspection shall be conducted with the COR and the contractor.
The paint on the entire hull from the keel to the deep load line shall be surveyed. All areas where the anticorrosive system (primers) have been disturbed or removed shall be identified and clearly marked. A written condition report with recommendations shall be submitted by the contractor to the COR within 24 hours after performing the joint inspection.
The report shall include a summary of the hull's condition, including an estimate of the total square-footage of the hull that requires a renewal of the anticorrosive system.
All blasting shall be done from above with the nozzles pointed down toward ground to prevent the spread of blast or water to the upper portion of the vessel.
Scaffolds, cherry pickers or other means shall be provided for use of personnel in blasting/power washing and painting.

All open fans, vents, doors, hatches, antennas and wiring, windows, nameboards, castle, ship’s bell, electrical outlets, navigation lights, wipers, spotlight, davits, winches, machinery and deck gear shall be sealed with plastic film or a suitable substitute prior to blasting and painting operations. As an option, equipment may be removed prior to blasting and reinstalled after the last coat of paint has dried.
Special care shall be taken to mask and fully protect the transducers, zinc anodes, and other underwater equipment against abrasion, damage, and painting.
Any damage to the vessel or its components due to lack of or improper painting/blasting protection shall be repaired to original by the Contractor at no additional cost to the Government.
The Contractor shall contact the COR to inspect and approve the blasting/painting protection prior to the start of the blasting process. It shall be the responsibility of the Contractor to maintain the blasting/painting protection for the duration of the blasting/painting process. At no time shall this be a cause for extension of contract time or additional cost to the Government.
All of the manufacturers and USACE preparation and environmental conditions must be met prior to beginning any operation. Surface temperature, humidity, wind conditions, dew point, and wet-bulb readings shall be checked and recorded at least twice daily.
