Oily Water System General Locations and Operation

Oily Water System The Oily Water System is designed to allow Fireboat Crew Members the ability to clear the machinery space bilges of any bilge water or oily residues which may accumulate in the VSP Room, Engine Room or Aft Hold. Hose/Wand stations are located within these spaces so the crews can suck up oily water residues easily. The air driven pneumatic Oily Water Transfer Pump is positive displacement, and has the ability to pull oily water from even difficult to reach areas of the machinery space bilges. The oily water is pumped into an Oily Water Holding Tank for storage. When the Oily Water Tank reaches its maximum capacity, the system can be configured to use the Oily Water Transfer Pump to discharge the oily water to a shore side tank, vacuum truck, slop barge or other facility that can safely process the waste.

Oily Water System Another feature of the Oily Water System is that several systems drain potentially oily water directly into the Oily Water Tank. This arrangement helps minimize the build up of oily residues that may otherwise end up in the machinery space bilges. The systems that drain directly into the Oily Water Tank: VSP Room Machinery Space Wash Basin (Via automatic sump pump) Crane Pedestal Drain Engine Room Escape Hatch Drain Containment Area Deck Drain Service Air System Auto Drains (Spit Valves) (Not reflected in As Built Drawing)

Oily Water System Oily Water System As Built
Take a look at this line drawing, and use it as a guide as we go through this system

Oily Water System The Oily Water Tank has a capacity of 240 US Gallons, but because we do not want to fill higher then 90 percent, its true capacity is 216 US Gallons. Once the Oily Water Tank is at maximum capacity, arrangements can be made to pump it out to some type of receiving facility, slop barge, shore tank, disposal truck, or even the clarifier at Station 15 (as long as it is still there). You must use the Oily Water Transfer Pump to discharge the Oily Water Tank. The tank fill and suction lines are independent, and only the suction line has a bell mouth, so you cannot use a vacuum pump alone to “suck” out the Oily Water Tank. You can however, use a vacuum pump in series with the Oily Water Transfer Pump.

Oily Water System The system has the following main components:
Oily Water Storage Tank – 240 US Gallons. Aft Engine Room, Port Side, just under Main Switchboard. Piping, valves, distribution manifold, vent and discharge connection. Pneumatic, positive displacement diaphragm pump – Yamada NDP, psi. Starboard Engine Room, on aft side of aft tonnage frame. In-line serviceable basket strainer on suction side of pump. Suction hoses with fittings and wands. System air supply, with electric-over-air solenoid switch and adjustable air-flow needle valves.

Oily Water System Oily Water Storage and Discharge
Oily Water Discharge is located in containment area on Starboard Side Main Deck, Aft.

Oily Water Tank Vent In the containment area you’ll see the vents for the Clean and Used Lube Oil Tanks, Oily Water Tank, Fuel Oil System, and the fill/discharge connections for these tanks.

Oily Water System Oily Water Storage and Discharge Clean Lube Oil Fill
Oily Water Discharge has a 1 inch Female Cam-Lock connection. The other 1 inch Female Cam-Lock connection is for Used Lube Oil Pump Off, and the 1 inch Male Cam-Lock connection is for Clean Lube Oil Fill. Used Lube Oil Discharge Oily Water Discharge

The Oily Water Storage Tank lies directly under the Main Switchboard. You can access the fill and suction valves from under the floor plates just in front of the Main Switchboard. Note the manual sounding tube

Oily Water Suction Line has a bell-mouth inside the bottom of the tank. There is an Tank Suction Isolation Valve (V10) (Normally Closed) right at the top of the tank The suction line then crosses the Engine Room under the floor plates and heads over to the distribution manifold on the Starboard, Aft Tonnage Frame

The Oily Water Transfer Pump discharges into the Oily Water Tank through the line indicated here. Oily Water Tank Fill Valve (V11) (Normally Open) must be open to allow you to fill the tank.

The individual bilge suction stations all tie in to the Oily Water Pump suction here Here is where the Oily Water Tank Suction comes up to the distribution manifold. This line came all the way from the port side of the E/R where the Oily Water Storage Tank is locate.

This is where the Containment Area Deck Drain “T’s” into the transfer pump suction This is the path the Oily Water follows from the tank to the transfer pump.

Oily Water Transfer Pump Suction Valve (V02) (Normally Closed)

The discharge line leaves the Oily Water Transfer Pump and heads back to the distribution manifold on the front of the tonnage frame. The suction line comes around the aft side of the tonnage frame and enters the Oily Water Transfer Pump.

Oily Water Transfer Pump Discharge Piping passes through Discharge Valve (V04) (Normally Closed) To Main Deck Discharge It may continue up to the Main Deck Containment area (discharging tank) OR back to Storage Tank (pumping out bilges) Discharge Block Valve (V05) (Normally Closed) To Oily Water Storage Tank

The oily water discharge tubing heads up the Main Deck Containment area.

Oily Water Tank Discharge Procedures Note: Any Lube Oil, Oily Water or Fuel Oil Transfer Operation on the new fireboats requires the Fuel Oil/Lube Oil/ Oily Water SOPs be followed. This is both a federal, state, and local law, and will probably be adopted as an LBFD fireboat policy/procedure (TBD). Since our vessel is capable of storing over 250 barrels of what the USCG considers a “dangerous liquid” (Fuel Oil), we are obligated by law to follow a Dangerous Liquid Transfer Plan for ALL Fuel Oil, Lube Oil, and Oily Water transfers on the new fireboats. We will be creating a Dangerous Liquid Transfer Plan as part of the Fireboat Program Operational Procedures. This will contain SOPs, training procedures for Person’s In Charge (PICs), and other information regarding all Dangerous Liquid Transfers on the new fireboats. The next slide is a review of the SOPs…

LBFD Fuel Oil/Lube Oil/Oily Water Transfer SOPs
Oily Water System Oily Water Storage and Discharge Oily Water Tank Discharge Procedures LBFD Fuel Oil/Lube Oil/Oily Water Transfer SOPs Person In Charge (PIC) – LBFD Fireboat Qualified individual (usually Fireboat Engineer), trained to supervise Fuel Oil, Lube Oil or Oily Water transfer operations on the fireboats. Conducts pre-transfer conference, completes Declaration of Inspection (fancy name for check list mandated by USCG regulations) as required, operates all valves and pumps associated with transfer, verifies and monitors tank soundings/volumes/weights and distribution of liquids, establishes primary and secondary means of communications to be used by all personnel, ensures all federal, state and local regulations are followed. Supervises entire transfer operation from start to finish and must be present during entire operation unless relieved by other PIC or Assistant PIC. Assistant PIC – LBFD Fireboat Qualified individual (usually second Fireboat Engineer) trained supervise and/or assist the PIC. Double checks and verifies PIC’s procedures. Safety Officer – LBFD Fireboat Qualified Captain. Monitors overall transfer operation for safety of personnel and environment. Has authority to stop operation at any time. Fireboat Pilot – Assist with transfer operation as directed by PIC. In charge of Deck Watch during transfer operation. Ensures vessel secure to pier, wharf, or dock. Maintains anchor watch or underway watch depending on type of transfer operation. Fireboat Deckhands (2) – Assist with transfer operation as directed by PIC. Assist PIC or Assistant PIC in Engine Room or on deck as directed. Assist Fireboat Pilot with Deck Watch as directed by Fireboat Pilot, but with permission of PIC.

Oily Water System Oily Water Tank Discharge Procedures
1. Display Bravo flag during day or all around red light at night

2. Put scupper plug into containment area. 3. Ensure containment area deck drain cap is in place.

4. Always have rags, spill pigs, buckets, and absorbent material available at containment/fill station during entire transfer. Place (1) 20# Dry-Chemical fire extinguisher near containment area. (This is a fuel oil discharge operation in the picture, just an example of having absorbent around)

5. Ensure diverter valve for containment area deck drain to Pump Engine #3 Overboard Discharge is closed (Position shown). Note: We advise that this valve ALWAYS BE closed. The containment deck drain was designed to drain the containment area into the Oily Water Tank in the event of an accidental fuel spill, lube oil spill, or oily water spill. Diverting overboard is for absolute emergency only!

6. Measure level of oily water in tank, calculate volume and determine what volume of Used L.O. you want to discharge. Always use two independent means of determining tank levels and volumes. Manual is generally more accurate then electronic gauging. One method verifies the accuracy of the other.

Oily Water System Oily Water Tank Discharge Procedures Conduct Pre-Transfer Conference with shore facility, vacuum truck, or barge operator (Receiving PIC): Establish primary and secondary means of communications. State oily water being discharged. Agree on quantity to be discharged based on your calculations. Agree on discharge rate and pressure maximums. If pumping to truck, determine whether vacuum pump will be used in conjunction with Oily Water Transfer Pump. Complete Declaration of Inspection (safety checklist) and sign if applicable. Verify discharge hose is in compliance with current hydrostatic test date and is rated for petroleum service. Make sure hose has compatible connections and/or adaptors. Note: Many of these steps may or may not apply if pumping to the clarifier at Station 15, or to a holding tank at either station. Nevertheless, always observe SOPs to the fullest extent applicable to the given operation.

8. Connect discharge hose to Oily Water Discharge. Do not open valve until ready to discharge! This should be the last valve opened.

9. Open V10 (Normally Close) 10. Close V11 (Normally Open)

11. Ensure Crane Pedestal Deck Drain to Oily Water Tank Isolation Valve is closed (Normally Closed) Note: This valve is under the Clean L.O. Tank in the Aft Hold.

12. Ensure all machinery space oily water suction station valves closed (Normally Closed) VSP Room (V09) FWD E/R (Not numbered) Central E/R (V08) Aft Hold (V09)

13. Open Oily Water Transfer Pump Suction (V02) (Normally Closed)

14. Open Oily Water Transfer Pump Discharge (V04) (Normally Closed) 15. Ensure Oily Water Transfer Pump Discharge Block Valve (V05) is closed (Normally Closed)

Oily Water System Oily Water Tank Discharge Procedures Double check your line up. (Good opportunity for Assistant PIC to check your work). Put all support personnel in place: One person to remain at discharge/containment station through entire transfer to verify connection does not leak. Other personnel can keep an eye on other stuff, check mooring lines, and make occasional checks of surrounding environment.

You are now ready to discharge Oily Water. Direct the person at discharge/containment station to open the Oily Water discharge valve. You may now tell the Receiving PIC (if applicable) you are commencing discharge.

20. Make sure all pneumatic pump needle valves are closed (CW) (Normally Closed)

21. Air solenoid “On” (Open service air solenoid)

22. Open needle valve on Oily Water Transfer Pump slowly (CCW) (it’s the lowest one of the three 25 GPM Yamadas). The pump will start pumping, so bring it up to about 40 to 50 cycles per minute.

Oily Water System Oily Water Tank Discharge Procedures Confirm with Receiving PIC (if applicable) that they are getting flow. Confirm with person at the discharge/containment area “no leaks.” If everything is looking good, increase the rate of the Oily Water Transfer Pump to about 60 to 80 cycles per minute. That should give you about 25 no more then 50 PSIG.

26. Verify flow out of your Oily Water Tank. Use two methods: Manual Sounding, and Tank Page on AMS Panel.

Example of discharging oily water from the vessel to shore-side tanks… Simple, but you must not spill a drop!

Oily Water System Oily Water Tank Discharge Procedures 27. Continue to monitor tank levels, connections, and vent through out the discharge operation. Do not leave containment/discharge area or Engine Room unattended during transfer. 28. You may suck the tank dry. The pneumatic pumps are positive displacement, and they will effectively pump, even without head pressure.

Oily Water System Oily Water Tank Discharge Procedures When the tank is dry, continue pumping air through the line to help push oily water out of discharge hose. Once you are satisfied, let the Receiving PIC know you are shutting down – then shut down the pump by turning the needle valve off, and turn the solenoid switch “off.” Close Tank Suction V10, Pump Suction V02, Pump Discharge V04. To drain discharge hose back into Oily Water Tank: Open Discharge Block Valve V05, and Oily Water Tank Discharge Valve V11. Leave Main Deck Discharge V01 Open.

Oily Water System Oily Water Tank Discharge Procedures Once you are satisfied the discharge hose is drained down, close all valves in the Oily Water System except for V 11. Disconnect hose, replace plug in cam-lock fitting, clean up, and put your stuff away. (Don’t forget the Bravo flag or all around red light!)

Oily Water System Oily Water Tank Discharge Procedures Notes on Using a Vacuum Truck when Discharging Oily Water Tank A vacuum pump on a disposal truck or barge, may be used in conjunction with the Oily Water Transfer Pump when discharging the Oily Water Tank. Just be careful not to overpower the pneumatic pump…

Oily Water System Oily Water Tank Discharge Procedures Notes on Using a Vacuum Truck when Discharging Oily Water Tank To use a vacuum pump in series with the Oily Water Transfer Pump: Configure system as you normally would for discharging using just the pneumatic pump. Commence the discharge with the Oily Water Transfer Pump first. Once it is pumping at full discharge rate, have the Receiving PIC start the vacuum pump. Observe the discharge gauge of the Oily Water Transfer Pump, and make sure it maintains at least 5 PSIG, and the suction gauge vacuum goes no greater then 25 inches. If the Oily Water Pump does not stay in these parameter, then it is not worth pumping in series to the vacuum pump. If this is the case, you will only be able to discharge with just the Oily Water Transfer Pump alone. Note: This system cannot be configured to “suck” the Oily Water Tank out with a vacuum pump alone.

Oily Water System Pumping Oily Water Out of Bilges
1. Make sure you have room in your oily water tank! Always use two independent means of determining tank levels and volumes. Manual is generally more accurate then electronic gauging. One method verifies the accuracy of the other.

2. Attach oily water suction hose/wand to Oily Water Suction Station in close proximity to bilge you wish to clear. Open the associated station valve (Normally Closed) VSP Room (V09) FWD E/R (Not numbered) Central E/R (V08) Aft Hold (V09)

3. Configure your Oily Water Tank Valves: Open V11 (Normally Open) Ensure V10 Closed (Normally Closed)

4. Ensure diverter valve for containment area deck drain to Pump Engine #3 Overboard Discharge is closed (Position shown). Note: We advise that this valve ALWAYS BE closed. The containment deck drain was designed to drain the containment area into the Oily Water Tank in the event of an accidental fuel spill, lube oil spill, or oily water spill. Diverting overboard is for absolute emergency only!

5. Ensure Crane Pedestal Deck Drain to Oily Water Tank Isolation Valve is closed (Normally Closed) Note: This valve is under the Clean L.O. Tank in the Aft Hold.

6. Make sure the Main Deck Discharge (V01) is closed (Normally Closed) and capped.

7. Open V02 (Normally Closed) 8. Open V04 and V05 (Normally Closed).

Oily Water System Start the Oily Water Transfer Pump in the normal fashion (other pump needle valves off, turn on solenoid switch, adjust needle valve on Oily Water Transfer Pump to efficient speed). Clear your bilge till satisfied, shut the system down, and clean up your stuff, and put all system valves back to their normal positions.

Oily Water System Drains to Oily Water Tank Five systems are configured to drain into the Oily Water Tank to minimize the amounts of oily effluents that drain into the Engine Room Bilges: Containment Area Deck Drain Service Air Water Separator and Spit Valve Drains VSP Room Wash Basin E/R Escape Hatch Coming Crane Pedestal Deck Drain

Oily Water System Drains to Oily Water Tank
Containment Area Deck Drain The Containment Area on the Aft, Starboard Main Deck has a deck drain. In the event you have a spill in the containment area, you can remove the deck plug, and configure the Oily Water Pump to pump out the Containment Area to the Oily Water Tank. Use T-handle to remove plug

Oily Water System Drains to Oily Water Tank
Notice here how the deck drain line connects to the Oily Water Transfer Pump suction via a three way ball valve. The builder configured the containment deck drain this way to give the end user the option to drain the containment area overboard through the Pump Engine # 3 Cooling Water Overboard Discharge. Containment Area Deck Drain Three way valve. Valve position to pump suction Note: Draining the containment area directly overboard is against the law unless it is a dire emergency!

Oily Water System Drains to Oily Water Tank Service Air Drains Most of the water traps and spit valves on the Service Air System are connected to a common 1/2 inch stainless tubing drain line that runs down the starboard side of the Engine Room. It connects to the 1 inch stainless Oily Water Transfer Pump discharge line leading directly into the oily water tank.

Oily Water System Drains to Oily Water Tank Service Air Drains
From Pump Discharge When you trace the Service Air Drain Line out, you will see how it travels aft, under the E/R floor plates in the Starboard E/R. It then passes under the Starboard GenSet, and connects to the Oily Water Pump Discharge near the starboard, aft tonnage frame. System Air Drain Line and Check Valve To Oily Water Tank

Oily Water System Drains to Oily Water Tank Crane Pedestal Drain
Inside the Crane Pedestal is a small 1 inch drain.

From the Crane Pedestal, The drain line drops down through the Aft Hold, and under the Clean Lube Oil Tank From Crane Pedestal To Oily Water Tank

Under the Clean L.O. Tank, we can clearly see the Crane Pedestal Drain and Check Valve. The Crane Pedestal Drain Valve will be Normally Closed. We recommend you only open this valve when draining the pedestal, because it connects to the Oily Water Pump Discharge line.

Here, just above the Oily Water Tank, you can see where the Crane Pedestal Drain connects to the Oily Water Pump discharge line and then drops into the Oily Water Tank.

Oily Water System Drains to Oily Water Tank Engine Room Escape Hatch
Above the Main Switch Board, Port, Aft Engine Room, is the Escape Hatch. Trace the 1 inch stainless drain line from there.

Oily Water System Drains to Oily Water Tank Engine Room Escape Hatch
From the hatch, it joins the line from the VSP Room Wash Basin Discharge. The hatch drain can be configured to: Drain into the Oily Water Tank, or Drain into the drain through the Port GenSet Cooling Water Overboard Note: In the picture, the three way ball valve is configured to direct the E/R hatch drain to the Port Genset Cooling Water Overboard

Oily Water System Drains to Oily Water Tank VSP Room Wash Basin
The VSP Room has a wash basin. It can be assumed, that occasionally, oily water from hand washing and E/R maintenance will end up in this sink, so the sump pump for this sink sends waste water to the Oily Water Tank (not the grey water tank) The sump pump works automatically by means of an internal float switch.

From the VSP Room Wash Basin sump, the drain line travels aft, through the Engine Room, and eventually drops down to the Oily Water Tank. The drop is right above the Bilge Manifold.

Both the VSP Room Wash Basin and the E/R Escape Hatch Drain share the same gravity feed directly into the Oily Water Tank. Note: This line, where it enters the tank, has no isolation valve.
