7.0 STATEMENT OF WORK

7.1 In the locations identified in Para 3.0, CHECKPOINT: Prior to the start of any productive work under this item, the Contractor shall witness Ship Force conducting an operational test of deck equipment near all work areas. Contractor shall document performance of test results, noting "as-found" conditions and listing all parties involved in test. Contractor shall submit findings to the MSCREP. All non-working equipment after this report will be the responsibility of the contractor.

7.2 Tag-Out all required systems and equipment. Drain and dispose of any liquid in accordance with all federal, state, and local regulations.

7.3 Accomplish the requirements of SSPC-SP1, Solvent Cleaning, using biodegradable detergent to remove all oil, grease, dirt and soluble salts from the surface of the specified decks. Products such as Chlor Rid (or equal) may be used as an aid in chloride removal provided that the product used leaves no residue that may be detrimental to coating adhesion. Final washdown shall be made with clean, fresh water at 2,500 to 3,000 psi. Upon completion of all water washing chloride testing shall be performed at random locations. If contamination is found, additional tests shall be made as necessary to determine the extent of contamination and to prove the success of remediation. The maximum allowable contamination concentrations shall be less than 10 ug/cm2 of chloride contaminants as determined by field or laboratory analysis using reliable, reproducible test equipment.

7.4 Temporarily remove, store and re-install interferences as required to accomplish the work specified.

7.5 CHECKPOINT: Prove deck drains clear and free flowing to the MSCREP. Plug or suitably blank the drain lines prior to the start of abrasive blasting.

7.6 CHECKPOINT: Prior to initiating surface preparation, the contractor shall ensure that the vessel's equipment is protected from damage caused by water jetting, dirt, blast dust or paint. Measures to be taken include, but are not limited to, the following:

7.6.1 Plug open ends of pipes, vents and ducts.

7.6.2 Grease and wrap all valve stems. Install filters on all air intake vents. Install covers on all fuel tank vents.

7.6.3 In all areas to be blasted and coated, record all ship's markings, including information, size, and color.

7.6.4 Install protective covering of a substantial nature on all portlights, windows, light globes and Landing light lenses to prevent damage to same by inadvertent blasting.

7.6.5 Mask all normally unpainted surfaces such as label plates, instructions, lights, and etcetera.

7.6.6 Protect mooring lines which cannot be stowed or removed for the duration of blasting and painting operations, by suitable means to prevent contamination by blasting abrasive, dust or overspray.

7.6.7 Fixed sprinklers shall be covered with sheet metal disks to prevent damage from abrasive blasting.

7.6.8 Prior to the start of productive work, protective covering shall be inspected and approved by the MSCREP. Deficiencies noted during this inspection shall be corrected and the MSCREP shall be afforded the opportunity to inspect and approve the corrective measures before work commences.

b. Contamination of the vessel and its equipment shall be reported to the MSCREP verbally immediately upon its discovery, followed by a written report within four (4) hours of the verbal notification. The contractor shall be responsible for cleaning the contaminated equipment and showing that the contamination has not caused damage to same. Cost to repair equipment damaged by such contamination shall be borne by the contractor.

7.7 The deck shall be blasted to the intersection of the deck and house on the inboard side and to the bulwark on the outboard side. This includes permanently attached fittings such as tie-downs, gunwale bars, hand holds/grabs, lighting fixtures bulkheads, coamings, and foundations, shall be abrasive blasted to near white metal in accordance with Surface Standard Preparation SSPC-SP10/NACE 2, Near White Metal Blast Cleaning utilizing blasting machines with vacuum recovery. The blast profile achieved shall be angular in nature and within the range set by the manufacturer’s product data sheet for the coating system being applied. Profile shall be determined using a Keane-Tator (or equal) Surface Profile Comparator. Testex (or equal) Replica Tape shall be used at a rate of one (1) reading per 1,000 SF for verification. Replica Tape shall be mounted, identified as to location and included as part of the final paint report.

7.7.1 Prior to the start of abrasive blasting the blast media shall be tested to ensure that it is not contaminated with chlorides, as determined by field or laboratory analysis using reliable, reproducible test equipment.

7.7.2 Small areas inaccessible to the vacuum blast machines and adjacent vertical structures including house bulkheads, gunwale bars, trough, foundations, etcetera, from the deck upward 4 inches, shall be prepared in accordance with Surface Preparation Standard SSPC-SP-11, Power Tool Cleaning to Bare Metal. Surfaces so prepared shall have at least a 1 mil surface profile.

7.8 All areas being abrasive blasted may, with the MSCREP’s approval, be prepared using ultra high pressure water jetting in lieu of abrasive blasting at no additional cost to the Government. If allowed, water jetting shall be performed in accordance with SSPC-SP WJ-2 utilizing equipment with vacuum recovery. Area noted in paragraph 7.6.2 may be prepared using Ultra High Pressure (UHP) hand lances. All water jetted areas shall be prepared to a WJ-2, SC-2 Condition. 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 an acceptable condition.

7.9 Prior to application of any coating, the area to be painted shall be inspected and approved by the MSCREP and the Paint Representative. This includes not only the initial coat of paint, but all subsequent coats as well.

7.9.1 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 random intervals to ensure that the surface has not been re-contaminated. If contamination is found, additional tests shall be made as necessary to determine the extent of contamination and to prove the success of remediation. Results of this testing shall be presented to the MSCREP at time of inspection for coating application.

7.9.2 The maximum allowable contamination chloride concentrations shall be less than 10 ug/cm2 of chloride contaminants as determined by field or laboratory analysis using reliable, reproducible test equipment.

Spot readings shall be taken at a rate of five per 1,000 square feet. DFT gages shall be calibrated, spot readings shall be taken and DFT tolerances shall be in accordance with SSPC-PA2, Measurement of Dry Coating Thickness with Magnetic Gages.

7.9.5 Immediately after abrasive blasting/water jetting, the crossbars on each tie-down fitting shall be inspected for damage and deterioration. Prepare a sketch of the deck showing the location of each tie-down fitting and indicating the results of the inspection. Submit three (3) copies of the completed sketch to the MSCREP immediately upon completion of tie-down inspection.
