SFLC Standard Spec 0000 par 3.2.11.

3.1.6 Temporary HVAC. If the contractor’s proposed cleaning plan (para 3.2.1 below) will degrade continuous operation of the ship’s HVAC system then the Contractor shall provide temporary ventilation to all impacted areas equivalent to the normal zonal ventilation rating for those spaces (i.e. maintain existing climate control) for the duration of work as described in SFLC Std Spec 0000.

3.1.7 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, 154 WPC 601-302, and 154 WPC 633-301.

NOTE

Be aware that the grey water system has few isolation valves and many openings that must be plugged or blanked to contain cleaning media.

15 (Rev-0)

Be aware that AC condensate drains into the Grey Water Tank at 8 separate locations. Any temporary disruption or degradation of climate control must be fully addressed by the cleaning plan.

For these reasons, based on lessons learned, it is suggested that chemical cleaning be used on sewage piping and grey water system piping be cleaned mechanically (e.g. waterjetting, etc.)

3.1.8 Cleaning Plan. No later than 7 days after the arrival conference, and prior to the start of cleaning work, the Contractor shall submit a cleaning plan CFR that contains the following:

A list of qualified personnel who will disassemble machinery or handle chemicals.

An SDS for every chemical proposed for use.

A step by step description of the procedures and methods that will be used to clean the systems

A list of locations in the sewage and grey water piping system where piping lines will be opened and components will be removed. At a minimum the piping shall be opened at 3 separate sewage system clean-out locations and 3 separate grey water system clean-out locations for “before and after” inspections to determine the extent of cleaning required and to verify cleaning was adequately performed. These locations shall be pre-approve by the

COR and included in the cleaning plan CFR.

NOTE

Coast Guard personnel will operate all shipboard machinery and equipment.

3.2 Operational test and inspection - initial. Prior to commencement of cleaning 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 and to determine a more precise scope of cleaning required. Submit a CFR detailing any required growth work or repairs identified during the operational test based on the observed condition of the systems. Use the most economical methods for accomplishing the work.

3.2.1 Inspection of Grey Water Tank. The Contractor shall open and inspect the grey water tank to determine the condition of the grey water tank coating system to the greatest extent practicable, pre-cleaning. Submit CIR detailing the condition of the grey water tank coating system and any noted discrepancies, include an estimated square footage of failed coating in the CIR.

3.3 Cleaning and Inspection Requirements. After the COR approves the “Cleaning Plan” the Contractor shall clean the piping and tanks and in accordance with the approved “Cleaning Plan”, and as described below. Clean, in their entirety, all sewage and grey water system interior surfaces (e.g. sewage and grey water ppg interiors, pump interiors, valve interiors, all sewage and grey water tank vent lines interiors, sewage vacuum switch manifold interiors, fire main sprinkler pipe interiors and spray hole interiors in main sewage tank used to flush sewage tank, overboard/to shore connection discharge pump and all related valve and pipe interiors, etc.) that may come in contact with sewage or grey-water, by removing all obstructions, clogs, uric scale, and waste build-up on piping and component interiors, ensuring subsequent free unobstructed flow of waste solids and fluids.

16 (Rev-0)

NOTE

Depending on the condition of the system at the contract start date, chemical cleaning may not adequately remove all obstructions, scale, and build-up present. More intrusive cleaning methods, such as pressure washing, flexible auger cleaning, or other mechanical means of cleaning, may be required to remove all obstructions, scale, etc. These more intrusive methods are in scope of this work item and the contractor may be required to use one or more them, in the appropriate quantities, to achieve minimum cleaning requirements.

3.3.1 Repairs. In addition to the cleaning and inspection requirement specified herein, the Contractor shall perform the repairs described in Table 2 beneath paragraph 1.1.1. If “NONE” appears in Table 2 then there are no known repairs required to the systems.

Before filling a system with descaler ensure all openings below the fill point are blanked off or plugged.

3.3.2 Chemical Cleaning of Piping. When chemically cleaning piping and component interiors use a commercially available biodegradable sewage/grey-water system descaler (e.g. SEW CLEAN, etc.) safe for use on stainless steel. Fill the systems with descaler and hold for a long enough period to clean the systems as described above. After cleaning is complete drain and dispose of all sewage and grey water system contents.

3.3.3 Tank Cleaning. Interior surfaces of the Grey Water Tank 3-17-0-W, Sewage Holding Tank 2-4-0-

W, and sewage vacuum accumulation tank shall be cleaned until free of all foreign materials, sediment, and sludge. Remove all persistent residues, residual wash media, and moisture with clean lint-free cloths.

Remove, clean, and re-install all tank interior components (e.g. TLIs, limit switches, eductors, etc.).

Renew all zinc anodes installed in the sewage tank and grey water tanks using Government-furnished property. 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.

3.3.4 Inspections. After cleaning, inspect the piping interior at the locations specified in the “Cleaning

Plan” using a borescope in the presence of the COR, verify that all solid deposits, visible to the unmagnified eye, have been removed. 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 and inspect for any indications of overheating or loose wiring or connections. Submit a

CFR.

3.3.5 Miscellaneous. Do not drain any fluids (e.g. sewage, grey water, fresh water, etc.) into any space, bilge, or exterior location. Take all precautions required to prevent contamination of personnel and spaces in accordance with all applicable Federal, state, and local regulations. Renew all disturbed soft components (e.g. seals, gaskets, o-rings, etc.). Do not use the sewage pump installed in the system to offload sewage system contents.

17 (Rev-0)

3.3.5.1 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.

3.3.5.2 Use of Coast Guard Sewage and Grey Water Disposal Facilities. If “YES” is denoted in table beneath paragraph 1.1 (Intent), the Contractor may offload and dispose sewage and grey water system contents into the Coast Guard pier facility tanks in lieu of a contractor furnished tank truck, otherwise the contractor shall dispose of all waste using the contractor’s disposal facilities.

3.6 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 COR inspects all work performed, close the tanks.

NOTE

Coast Guard personnel will operate all shipboard machinery and equipment.

3.7 Operational test – post repairs. After completion of work, the Contractor shall thoroughly test all disturbed components and systems and accomplish the following tasks in conjunction with each other as appropriate, in the presence of the Coast Guard Inspector, and submit a CFR:

3.7.1 Adjust the set point on each of the vacuum pressure switches (as applicable) to the set points noted previously.

3.7.2 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.

3.7.3 Leak test. After all system components are reinstalled, the Contractor shall test all disturbed piping for leaks, as follows:

Run water down all disturbed grey water system piping runs for 5 minutes.

Ensure the system holds vacuum without cycling for at least 20 mins.

Place both vacuumarator selection switches in the "RUN" position. Allow vacuumarator pump to run until system operating pressure of -0.40 to -0.55 bar is reached. Observe vacuum tank pressure gauge. Place both vacuumarator selection switches in the "OFF" position. (NOTE: A vacuum loss of more than 0.14 bar indicates an air leak exists in the system.) Verify vacuum system pressure remains between -0.40 to -0.55 bar for 20 minutes.

Record pressure value and include in the CFR.

Perform smoke leak test on vacuum portions of the sewage system where the contractor has disturbed a mechanical joint.

Closely monitor the systems for leaks. Repair all leaks detected. Repeat test and inspection tasks until no leaks are detected.
