3. REQUIREMENTS
3.1 General.
3.1.1 CIR.
None.
3.1.2 Tech Rep.
Not applicable.
3.1.3 Protective measures. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces near the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness.
3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).
NOTE
Coast Guard personnel will operate all shipboard machinery and equipment.
3.2 Operational test - initial. Prior to commencement of work, the Contractor shall witness Coast Guard personnel perform an operational pre-test of all items and shipboard devices to be disturbed, used, repaired, or altered, (e.g. TLIs, pumps, etc.) to demonstrate existing operational condition. Submit a CFR.
3.3 Temporary Sanitary and Sewage Facilities. Whenever sewage or grey water collection service is disrupted due to contractor repairs, the Contractor shall provide temporary facilities in accordance with SFLC Standard Spec 0000 par 3.2.11.
3.4 Personnel qualification. The Contractor shall ensure that personnel accomplishing this work are qualified and experienced in operating the pressurized water system and handling the chemicals. For each operator/cleaning technician, submit documentation of applicable experience and training obtained within the last twelve months along with the Cleaning Plan (see paragraph 3.5.2 (Plan Submittal)).
3.5 Cleaning and Inspections. The Contractor shall perform the following, refer to Coast Guard Drawings 154 WPC 506-201, 154 WPC 506-301, 154 WPC 528-301, 154 WPC 593-301, 154 WPC 593-303, and 154 WPC 601-302. Take all precautions to prevent contamination of personnel and spaces in accordance with all applicable Federal, state, and local regulations.
3.5.1 Cleaning plan. The Contractor shall submit a written cleaning plan to the COR at least 48 hours prior to start. The plan shall list step by step procedures necessary to ensure that all foreign debris is removed from the piping system and tanks, and an MSDS for every chemical proposed for use. Upon approval of the plan, the Contractor shall proceed with the cleaning of all horizontal and vertical runs of the piping system at no more than 25-foot intervals. Ensure that the procedure includes the following:
· Cleaning methods. Do not use the sewage pump installed in the system to offload sewage system contents. The Contractor may offload and dispose sewage system contents into the Coast Guard pier facility tanks in lieu of a contractor furnished tank truck. Describe how a smoke test to verify no vacuum leaks will be performed (e.g. pressurizing vacuum ppg w/smoke, or putting a vacuum on ppg and going around the ppg exterior with a smoke pot, etc.)
· All safety precautions required during cleaning operations.
· List of qualified personnel who will operate machinery or handle chemicals (see paragraph 3.3 (Personnel qualification) herein).
· Locations in the sewage and grey water piping where cleaning will take place, and any additional fittings necessary.
· Sequence of each location that ensures all piping sections will be cleaned and all foreign debris removed.
CAUTION
Although the Coast Guard prefers pressurized water as the cleaning fluid, the Contractor may propose chemical cleaning as an alternative, providing that the proposed chemical cleaning agent conforms to DOD-STD-2187 (where applicable), is environmentally safe, and pre-approved by the COR. Due to the fact that system piping has historically been difficult to clean by pressure washing only, chemical cleaning is usually required to successfully complete the cleaning process.
3.5.2 Plug log. Plug all unattended openings in the system. Plugs shall be fitted with a lanyard, ring or other device to prevent loss of the plug inside the system. Create and maintain a written log of each plug that specifies the location of each. Remove and dispose of all plugs upon completion of work. Furnish the plug log to the Coast Guard Inspector during the performance of close-out inspections.
3.5.3 Cleaning and flushing requirements.
3.5.3.1 Sewage and grey water piping. Clean, inspect, and flush all sewage pipe (approximately 600 linear feet) and grey water pipe (approximately 150 linear feet) until all visible calcium carbonate deposits, solid deposits, and build-up are removed from pipe walls and the discharge cleaning media from the piping being cleaned is free of all visible scale and deposits.. System valves shall be replaced with temporary spool pieces during cleaning.
3.5.3.2 Sewage and grey water tanks and other components. Clean and inspect all sewage system and grey water system component interior surfaces (e.g. all sewage and grey water tank vent lines, Grey Water Tank 3-17-0-W, sewage vacuum accumulation tank interior, sewage vacuum switch manifold interior, both sewage vacuum pump interiors, Sewage Holding Tank 2-4-0-W, fire main sprinkler pipes and spray holes in main sewage tank used to flush sewage tank, overboard/to shore connection discharge pump and all related valves and pipes, etc.). Remove cleaning media and residues continuously from the tank during the washing process. Clean all tank interior surfaces free of all foreign materials, sediment, and sludge and remove all persistent residues, residual wash media, and moisture with clean lint-free cloths. Remove and dispose of all sewage system contents and collect, contain, and dispose of all wash media and cleaning materials in accordance with all applicable Federal, state, and local regulations. Remove all unused chemicals from USCG property immediately upon completion of work item.
3.5.3.3. Miscellaneous. Do not drain any fluids (e.g. sewage, grey water, fresh water, etc.) into any space, bilge, or exterior location. Remove, clean, and re-install all tank interior components (e.g. TLIs, limit switches, eductors, etc.). Renew all disturbed soft components (e.g. seals, gaskets, o-rings, etc.). Renew the zinc anode installed in the sewage tank.
3.5.4 Inspections. Inspect the piping interior using a borescope in the presence of the COR, verify that all solid deposits, visible to the unmagnified eye, have been removed. Continue the cleaning process until all visible solid deposits are removed from the pipe walls. Visually inspect all system components (e.g. TLIs, limit switches, pressure switches, tank interior surfaces, fasteners, gasket seating surfaces, manhole cover surfaces, etc.) for excessive wear, damage, and all other notable discrepancies. Open and vacuum-clean the control panel assembly. Inspect the control panel assembly for any indications of overheating or loose wiring or connections. Submit a CFR.
3.5.5 Closing tanks. The Contractor shall notify the COR at least 24 hours prior to closing the tank. After completion of all authorized repairs and after the Coast Guard Inspector inspects all work performed, close the tanks.
NOTE
Coast Guard personnel will operate all shipboard machinery and equipment.
3.6 Operational test – post repairs. After completion of work, the Contractor shall thoroughly test all disturbed components and systems and accomplish the following in the presence of the Coast Guard Inspector, and submit a CFR:
3.6.1 Adjust the set point on each of the vacuum pressure switches (as applicable) to the set points noted previously.
3.6.2 Verify operation of the low and high level switches/alarms and that the pumps cycle from lead to lag status during operation. Demonstrate proper operation of tank TLIs to prove satisfactory operating condition.
3.6.3 Upon completion of testing and, in the presence of the Coast Guard Inspector, pump tank(s) to the limit of the ship’s installed pumps.
3.6.4 Leak test. After all system components are reinstalled, the Contractor shall test all disturbed piping for leaks, as follows, and submit a CFR:
· Plug all system openings (except the highest) and fill system with water to the point of overflow. Ensure that the water level does not go down (without adding any water) for sufficient time to inspect the entire system (no less than 15 minutes).
· Perform smoke leak test on vacuum portions of the sewage system.
· Closely monitor the system for leaks. Repair all leaks detected.
· Repeat test and inspection until no leaks are detected.
