7.0 STATEMENT OF WORK REQUIRED:
7.1 Mark, remove and properly store interferences. Upon completion of the work required by this item, reinstall interferences and prove operational. Prove both deck drains to be clear and free flowing. Plug the drains to preclude introduction of product and/or debris resulting from this work item. Upon completion of the decking renewal, remove the plug and again prove the drain to be clear and free flowing. The Chief Mate shall witness the testing of the drain. Install protective covering to protect the vessel's equipment and to contain the dust generated by this work item to the affected compartment. The Contractor is to take his own measurements to verify the exact quantities of product required. The installation is to be completed using the guidance in reference 2.1 and 2.2.
7.2 Chip up and remove the existing tile deck covering and underlayment in its entirety, including coving. Debris shall be removed from the vessel and properly disposed of on a daily basis. Scale the entire deck, the bulkheads up to a line 3" above the deck and retainer rings around deck drains, to bare metal in accordance with the Steel Structures Painting Council Surface Preparation Standard SSPC-SP-3, Power Tool Cleaning. Blow down and/or vacuum the compartment to remove all dirt and dust generated by the surface preparation activities.
7.2.1 The bridge head has a terrazzo deck covering which has some break down around the drain. The defected area will need to be removed and the area filled with Peran STB. Due to the difference of material it will require the complete deck to be replaced.
7.3 Inspect the surface preparation with the USMMI Port Engineer and the Chief Mate. The inspection shall include the condition of all permanently attached fixtures in way of the Peran STB Marine Decking installation including retainer rings around deck drains. Upon approval of the surface preparation by the USMMI Port Engineer, apply one (1) primer coat of USMMI furnished Amercoat 240 buff paint and one (1) barrier coat of Amercoat 240 red to all prepared surfaces at 4-6 mils DFT per coat.
7.4 Upon approval by the USMMI Port Engineer, wipe down the painted surfaces with solvent. When dry, install the Peran Primer 1 at 0.2 kg/m2 underlayment. The underlayment shall and shall fair-in irregularities in the deck including weld seams, depressions, etc. Total thickness of the underlayment shall be as necessary to achieve a smooth, even surface. Upon inspection and approval of the Primer 1, install the Primer 2 Peran STB Marine at 0.3 kg/m2 and then apply the scatter Color Quartz sized 7/8 at 0.5 kg/m2. Once the cure has been achieved, apply body coat Peran STB Marine (A+B) at 0.75 kg/m2 mixed with Peran STB Marine Filler C at .075 kg/m2. The body coat shall be sloped for positive drainage to the deck drains and shall be coved up the bulkheads 3". This is then to be covered with scatter Color Quartz size 7/8 at 3.0 kg/m2 at full blind. When cured, grind the surface to a smooth and fair surface. The final surface shall be nonporous, smooth and free of pits, spalls, and crevices. The color quartz chips shall be uniformly distributed, firmly embedded and exposed at the surface. Cracks or voids found in the finish are will be rejected defects. Such defects shall not be patched. Acceptable corrective action shall be removal and reinstallation of the Body coat and STB Marine filler mix. When grinding of the surface is completed, blow down and vacuum the entire compartment, including protective covering and fixtures in the compartment.
7.5 Upon the Chief Mate’s approval, apply the Peran STB Marine Sealer at 0.2 kg/m2. The finish shall be an even gloss and free of blotches.
7.6 Clean and paint disturbed surfaces to match the surrounding areas with USMMI furnished paint. Test the drainage in the compartment. Prove that the drainage is positive and without low spots which would tend to collect water. Remove all protective covering. Clean the vestibules and leave in a condition ready for use.
