How does a Copt system work?

The COPT (Cargo Oil Pump Turbine) condenser, condenses steam under vacuum. It is used to condense low pressure steam before it enters the boiler feed pump. Twin jet ejectors for creating the vacuum, as well as the jet ejector condenser are also supplied.

How do cargo pumps work?

The cargo pump has a built-in hydraulic motor connected to the impeller by a short independent shaft. Motor, shaft and bearings are lubricated and cooled by the hydraulic driving oil. The pump impeller rotates and acts as a non-return valve to prevent cargo from returning back to tank.

What types of cargo pumps on tankers?

Positive Displacement pump:

• Reciprocating Pump.
• Screw pump.
• Gear pump.
• Piston pump.
• Ram type pump.
• Vane pump.

Where are the cargo pumps located in an oil tanker?

Cargo oil pumps are installed in the pump room, which is usually located in the stern of the vessel, between the tanks and the engine room. The pumps are installed as low as possible. At the beginning of the pumping process the inlet head is relatively large.

How does a reciprocating pump work?

The reciprocating pump works on the principle of positive displacement. A reciprocating piston pump consists of a piston that moves back and forth in a cylinder. The piston is connected with a crankshaft with the help of a connecting rod. This piston moves as the connecting rod move due to the motion of the crankshaft.

What is the purpose of the relief valve of a cargo pump?

The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits.

What is an inert gas or IG system on tankers?

Inert gas system is the most important integrated system for oil tankers for safe operation of the ship. Inert gas is the gas that contains insufficient oxygen (normally less than 8 \%) to suppress the combustion of flammable hydrocarbon gases.

What is a turbine pump and how does it work?

Turbine pumps are dynamic pumps, meaning they utilize fluid momentum and velocity to generate pump pressure. Specifically, they are centrifugal pumps, which generate this velocity by using an impeller to apply centrifugal force to the moving liquid.
