Important Tanks in Engine Room at Ship - Engine Room is where the ship's main engine and tank. In this space there are various ship tanks. What are the types of tanks on the ship.

This is the Important Tank in the Engine Room at Ship

• Fuel Oil Tanks
  No. 1 HFO Tank (P)
  No. 1 HFO Tank (S)
  No. 2 HFO Tank (P)
  No. 2 HFO Tank (S)
  
  Note: There are four heavy fuel oil (HFO) tanks which is also called as bunker tanks. These are the highest capacity tanks on ship. Two tanks are located in port side and two are in starboard side generally. (P = Port side, S = Starboard side).
  
  HFO Service Tank
  HFO Settling Tank
  HFO Low Sulphur Service Tank
  HFO Low Sulphur Settling Tank
  MDO Tank (P)
  MDO Tank (S)
  MDO Service Tank
  MDO Settling Tank
  
  Note: There are two marine diesel oil (MDO) tanks, one is located in port side and other is in starboard side.
  
  There are service and settling tanks for HFO as well as MDO. Settling tank is used for purification of oil by gravity separation technique. Service tank is used for daily use prepared oil for respective applications. (MDO = Marine Diesel Oil).
• Lubricating Oil Tanks
  M.E L.O Sump Tank
  M.E L.O Storage Tank
  M.E L.O Settling Tank
  G.E L.O Storage Tank
  G.E L.O Settling Tank
  Cylinder Oil Storage Tank
  Low TBN Cylinder Oil Tank
  
  Note: There are lubricating oil tanks for main engine as well as generator engine. L.O Sump tank is used for supplying lubricating oil for purification. It is also called as drain tank. Storage tank is used for lube oil storage purpose and settling tank is used for purification by gravity separation. Lube oil is needed for main engine as well as auxiliary engine, that’s why there are separate tanks for auxiliary and main engine.
  
  There is also cylinder oil tank for cylinder lubrication purpose as it is done through lube oil having some special characteristics. (TBN = Total Base Number).
• Fresh Water Tanks
  H.T F.W Expansion Tank
  L.T F.W Expansion Tank
  Fresh Water Storage Tank
  
  Note: Fresh water storage tank is used for storage of fresh water for general purposes like drinking, washing etc.
  
  There are two types of expansion tanks used at ship for cooling purpose mainly. H.T F.W is used for cooling of main engine and L.T F.W is used for cooling of generator and for general purposes other than main engine. (L.T F.W = Low Temperature Fresh Water, H.T F.W = High Temperature Fresh Water).
• Bilge, Sludge & Sewage Tanks
  Oily Bilge Tank
  Bilge Holding Tank
  Sludge Tank
  Sewage Holding Tank
  Waste Oil Service Tank
  
  Note: Bilge water or bilge is collected in Oily Bilge Tank and this bilge water is transferred to Bilge Holding Tank through bilge pump. Sludge Tank is used to collect the sludge discharged from oil purifiers and other means. Sewage Holding Tank is used for holding sewage collected from sanitary system.  Waste Oil Service Tank is used to collect waste or unwanted oil onboard.
• Other Special Tanks
  Stern Tube L.O Drain Tank
  Emergency G.E M.G.O Tank
  Cascade Tank (with Observation Tank)
  M.E Scavenging Air-box Drain Tank
  M.E Air Cooler Chemical Cleaning Tank
  Stern Tube L.O Gravity Tank
  Soot Drain Tank
  
  Note: Stern Tube Lube Oil system is maintained by drain tank and gravity tank. There is an emergency marine gas oil tank for generator engine. Soot Drain Tank is used for collecting soot washing of economizer. Cascade Tank and Observation Tank is used for boiler feed water system.
