Where are the steam reciprocating pumps on an oil tanker?
For the most part, they had a single line which ran forward and aft from a midship pump-room, in which were housed two steam reciprocating pumps. One pump served the tanks forward of the pump-room, while the other dealt with the oil from the tanks aft of this pump-room.
How does the overflow tank on a marine engine work?
Fitted in the overflow tank is a level alarm which will be activated when the tank is a quarter full. All tank vents are fitted so that oil cannot overflow onto deck or into machinery spaces which may lead to fires. The vent from the overflow tank is led onto deck and fitted with wire gauze diaphragms.
What is the loading and discharge system of an oil tanker?
The arrangement of loading and discharge lines is collectively known as the Ship’s Cargo System . The first oil tankers to carry petroleum products in bulk were equipped with very simple pumping systems.
What should the pressure be between service tank and booster pump?
Piping between a service tank and a fuel transfer or booster pump is rated as low pressure. However, between each pumping stage, pressure increases. It is a mistake to assume that even if a pipe’s pressure is relatively low, fuel will not spray from a crack or small hole.
Where is the fuel oil transfer pump located?
There is no elevated fuel oil piping adjacent to the engine. The fuel oil piping between the day tank and the engine drops down from the tank and runs below the elevation of the engine until it reaches the engine. The transfer pumps and auxiliary pump are located in the engine room.
Where does the fuel oil overflow tank go?
There is only pump cut-in limit switch is provided in the service tank because service tank has to be full at every time i.e. it overflows to the settling tank. In case if settling tank overflows then it goes to the fuel oil overflow tank. For Detailed Explanation of Settling Tank and Service Tank, Read:- Engine Room Layout – Deck 1
For the most part, they had a single line which ran forward and aft from a midship pump-room, in which were housed two steam reciprocating pumps. One pump served the tanks forward of the pump-room, while the other dealt with the oil from the tanks aft of this pump-room.
Why do you need a pressure and flow oil pump?
The oil is the literal lifeblood of your engine, and the oil pump is its heart. Adequate lubrication is absolutely essential, and making sure that we’ve got plenty of pressure and flow to all the right places is what makes engines live and last.
