Bilge Pumping Systems General Locations

Bilge Pumping Systems There are three separate, but related Bilge Pumping Systems 1. Bilge Pump and Manifold 2. External Bilge Pump-Outs 3. Main Engine Raw Water Emergency Bilge Pump. Outs

Bilge Pumping Systems • Most of these snapshots will focus on the Bilge Pumping Systems and the General Locations of their components. • We will discuss the Fire/General Service/Ballast Pump Systems at another time. • Operation of the Bilge Pumping Systems will also be described later.

Bilge Pumping Systems There are two pumps associated with the Bilge System that may be used interchangeably or in parallel to: • • • Pump out bilges Provide Fire Fighting Water for fires on board the fireboat Ballasting Operations if needed (highly unlikely) Provide water for gross HAZMAT Decontamination Shower De-Water Off Ship Firefighting Systems

General Locations Pumps, Discharge and Suction valves located on skid – port, aft engine room. • • Pumps and Motors Valves and strainers are very accessible Pumps are identical and may be configured to do the work of the other, (redundancy) or work with the other (increase flow or pressure) “Designated” Fire/General Service/Ballast Pump “Designated” Bilge Pump Discharge Valves (There are four)

General Locations Bilge Pump and Fire/G. S. /Ballast Pump Motor Controllers are located on starboard side of Main Switchboard in Engine Room Fire/GS/Ballast Pump Bilge Pump

General Locations You can also start the Fire/G. S. /Ballast Pump Remotely from Port, Main Deck Entry Fire Control Station Note: Make sure your system valves are configured properly for remote operation! More on this when we cover operations.

General Locations You may also start the Fire/G. S. /Ballast Pump Remotely from the Wheelhouse Fire Control Station. It is on the Port Forward Bulkhead by the Engineers Forward Console. Note: Make sure your system valves are configured properly for remote operation! More on this when we cover operations.

General Locations Overboard Discharge Valve • Coming off the discharge manifold of this system, the branch line loops overhead and runs to the port side shell, just forward of the Port Generator. • This valve will normally be shut!

General Locations Suction Valves and Basket Strainers

General Locations Normally Shut Sea Chest Suction Block Valves • Just below skid, aft of pumps Normally Open

General Locations Sea Chest Valves • Directly below skid, underneath the suction distribution valves. There are two valves here: • A manual globe check valve • Remote actuated butterfly valve (This valve allows remote starting of the Ballast/On-Ship Fire Fighting/General Service Pump Normally Open

General Locations Here is a little different view of Sea Chest Valves for this system. Note: Bilge, Ballast/Fire/General Service Pumps draw water form the Shared Firefighting Sea Chest. Remote Actuated Sea Chest Valve Manual Sea Chest Valve (Normally Open)

General Locations The Remote Sea Chest valve for the Bilge and Fire/G. S. /Ballast systems is operated from the remote switch on the Port Main Deck Entry Fire Control Panel, or the Wheelhouse Fire Control Panel

General Locations Bilge Suction Manifold • Inboard side of skid • Allows you to choose which bilge you are pumping out. • These valves will be labeled! • Branch lines run under floor plates and distribute to the following spaces: • Engine Room Starboard • Engine Room Port • Aft Machinery Space • VSP Room • Tank Void (Where the Potable, Grey and Black Water Tanks are located • Chain Locker

FWD Tank Void Chain Locker VSP Room Aft Machinery Space Port Engine Room Starboard Engine Room General Locations Bilge Suction Manifold

General Locations Bilge Suction Distribution Lines: • Each Bilge Suction Valve has a branch line that runs under the machinery space deck plates. • If it is taking suction from a space outside the engine room, it may have to penetrate several bulkheads before reaching its intended space. • It will terminate in the lowest portion of the bilge space, and have either a Rose Box, or Mud Box terminus to prevent debris from getting sucked into the distribution line. This one here is for the Aft Machinery Space (Aft Hold): • • • Note how it comes through the bulkhead from the adjacent Engine Room See the Rose Box? Note also the Bilge Level Alarm Sensor (Looks familiar huh? )

General Locations Rose Box A little better view of bilge suction in Aft Machinery Room

General Locations Bilge Suction Distribution Lines Here is an example of a Mud Box: • Essentially a serviceable, in-line strainer basket. Starboard Engine Room Bilge • It drops down from the strainer body to the bottom of the bilge and terminates as an open pipe VSP Room

General Locations Here is where the Bilge suction would be under the floor plates in port side of the VSP room, aft bulkhead.

General Locations Bilge Level Sensors Port Engine Room Bilge Suction. • Its actually just under and outboard of the Bilge, Ballast/G. S. /Fire Pump skid • Still pretty messy down there!

General Locations External Bilge Pump-Out Suction and Rose Box (Will discuss this system in the near future) E/R Bilge Level Sensor Port Engine Room Bilge Pump Suction

General Locations Port E/R Bilge Suction Mud Box • Under deck plates at foot of Fire Pump #2

General Locations Bilge Suctions related to the Tank Void The Tank Void contains the Grey Water, Black Water, and Fresh Water Storage Tanks Access to the Tank Void is from the EMS Room through a deck hatch. (Technically a confined space so follow your entry protocols!)

General Locations This is where the Tank Void Bilge Suction comes out from aft bulkhead and drops into the Tank Void Bilge Grey Water Tank Void Bilge Suction (The finger is actually pointing at the Chain Locker Bilge Suction Branch Line)

General Locations This line loops around from the aft bulkhead penetration of the Tank Void and come up to penetrate the aft Chain Locker bulkhead, starboard of centerline It has a Rose Box on the other side of this bulkhead. Chain Locker Bilge Suction Branch Line (There are two bolted access covers to chain locker: One above the chain manger and one below)

General Locations You can open this valve – located directly aft, and under the Bilge Pump skid – to pump out the Engine Room bilges. It was put in place to keep the Bilge Pump operational in the event the Bilge Pump Strainer or Bilge Manifold becomes fouled. Bilge Pump Direct Engine Room Bilge Suction Valve

Back-Up Bilge Pumping Systems General Locations Main Engine Raw Water Emergency Bilge Pump-Outs If things get really messy, and you lose both your Bilge Pump, and your Ballast/General Service/Fire Pump, you can still pump out your Engine Room Bilges by opening the Propulsion Engine Raw Water Pump Emergency Bilge Suction Valves. Note: Port and Starboard Main Engines need to be running to make this work, and this is a last ditch system.

Back-Up Bilge Pumping Systems General Locations Main Engine Raw Water Emergency Bilge Pump-Outs This is the Starboard Main Engine Emergency Bilge Pump-Out Valve • Opening this valve allows the Starboard Main Engine Raw Water Pump to act as an emergency bilge pump. • We will discuss how to put this system into operation later. STBD M. E. Raw Water Pump

Back-Up Bilge Pumping Systems General Locations Main Engine Raw Water Emergency Bilge Pump-Outs Starboard Main Engine Raw Water Emergency Bilge Pump. Out Valve is located below a deck plate just to the starboard of Fire Pump #1, right by the Mud Box for the Starboard Engine Room Bilge Suction.

Back-Up Bilge Pumping Systems General Locations Main Engine Raw Water Emergency Bilge Pump-Outs Port Main Engine Raw Water Emergency Bilge Pump-Out Valve is located flush on a deck plate just to the starboard of Fire Pump #2 It is just forward of the Bilge and Ballast/G. S. /Fire Pump skid. You don’t have to lift deck plates to access it.

General Locations External Bilge Pump-Outs The Outlets are 2 ½ inch threaded female NST connections. They are designed to connect to an eductor suction in order to pump out the bilges in a dire emergency. Sucks out VSP Room: Port Main Deck Forward Sucks out PORT Engine Room: Port Main Deck By Shore Power Sucks out STBD Engine Room: Starboard Main Deck Forward, by Grey and Black water MARPOL Connections.

General Locations External Bilge Pump-Outs They drop from the main deck, and directly down into the bilge of the space to pump out. The three spaces that have these type of pump outs are: 1. STBD Engine Room 2. PORT Engine Room 3. VSP Room This one is for the VSP Room and comes from the Port Main Deck, drops into the port side bilge of the VSP Room and terminates in a Rose Box.
