How do you make a cargo oil pump turbine?
How To Start A Cargo Oil Pump ( C.O.P.T ) In 14 Simple Steps
- Check and drain water from the lube oil sumps for the cargo oil pump turbine.
- Check and Open Sea water overboard Valve.
- Open Vent valve for the Condenser.
- Open The discharge and Suction Valves for the Sea water pump for vacuum cooling evaporator.
What is cargo oil pump turbine?
What is COPT? Cargo Oil Pump Turbine (COPT) System is found on the Oil Tankers. It has two systems working together to collectively discharge the oil. One system is the driving force which gets the power from steam to drive the second system, the centrifugal pump system.
What is the use of cargo pump during cargo operation?
The pump design allows operation with a minimum of liquid in the tank which saves time spent for drainage and tank cleaning. The Framo cargo pump has a built-in efficient stripping system. Condition based maintenance Seal monitoring is performed from the cargo pump top plate by purging the cofferdam.
What is a cargo pump?
Cargo pumps are used to to load large volumes of fuel oil on cargo shipping vessels at the departure port and unload at the arrival destination. The cargo oil pumps installed to complete this transfer of are usually screw pumps or gear pumps thanks to their ability to handle lubricating fluids.
How do you start a cargo oil pump?
Start up
- Lubricating oil sump to be checked for water contamination and drained as needed.
- Open the vacuum condenser inlet and outlet cooling water valves, cooling pump suction and discharge valves.
- Open ejector inlet and outlet valves.
- Open lubricating oil cooler inlet and outlet cooling water valves.
How do I start a Copt?
STARTING
- Check the lube oil sump level.
- Start the lube oil priming pump and check the pressure.
- Operate the vacuum condenser seawater pump suction and discharge valves to obtain a flow through the condenser.
- Switch on the breaker for vacuum condenser pump.
- Start the pump and check sea water pressure.
What is the maximum volume of cargo tank?
The volume of any one centre cargo oil tank shall not exceed 50,000 cubic metres.
What is Framo cargo pumping system?
The Framo cargo pump is a vertical single-stage centrifugal pump powered by a hydraulic motor for safe and efficient operation. All of our cargo pumps are made in stainless steel and designed with a smooth and easy-to-clean surface featuring a limited number of flanges for a superior ability to pump any liquid.
What are the precautions before starting a steam turbine?
Check first and second stage steam pressure. Check condenser vacuum and water level. Check lube oil pressure and vibration levels. Check turbo generator speed, voltage, frequency, vacuum, condenser level and other parameters.
What type of pump is widely used as cargo pump in tanker ship?
Centrifugal Pumps
Centrifugal Pumps The pump increases the liquid’s velocity by means of a rotating impeller.
How do we control the pressure in cargo tanks?
On LNG vessels cargo tank pressure is almost always controlled by burning the boil-off in the main propulsion system or in rare cases (e.g. emergency) by venting it to atmosphere. If the pressure above a boiling liquid is increased, vaporization from the surface is reduced, and vice versa.
What is ballast pump?
Ballast pumps are crucial for the operation of most vessels. They pump water in and out of the ballast water tanks during loading, off-loading and trim of the vessel. The pumps often require low NPSHr and high flow. Pressure can be increased if a Ballast Water Treatment System is installed.
How long does it take to warm up a steam turbine?
approximately five to nine hours
They should be warmed up and cooled down slowly to minimize the differential expansion between the rotating blades and the stationary components. Large steam turbines may require approximately five to nine hours to warm up.
What are the two basic types of steam turbines?
Two types of steam turbines must be considered, condensing and noncondensing.
How do you calculate cargo in an oil tanker?
We need to convert the volumes to the weight of the cargo in each tank. We need the density of the cargo to convert the volume of cargo to the weight. And as the density also changes with the temperature, we would need the density of the cargo at the cargo temperature to convert the observed volume to weight.
What is PV breaker on tanker?
Pressure-Vacuum (PV) Breaker PV Breaker works on the principle of set water column filled in it. It allows the pressure to release from common IG line by emptying out the filled water in PV breaker. It also allows to break the vacuum by allowing the air inside the tanks through common IG line.
What pump is used to strip cargo in oil tanker?
Eductors/Ejector An eductor is used for stripping tanks. It has no moving parts and therefore easy to maintain. It operates on Bernoulli’s principle. The driving propellant (fluid from main cargo pump), is forced through the nozzle, thereby creating a vacuum on the suction side.
But the most common arrangement is the one with centrifugal pump; driven by a steam turbine. Due to their wide use and design factors; a cargo pump is also referred as cargo oil pump turbine assembly.
What is centrifugal pump turbine?
A centrifugal pump turbine or C.O.P.T in short when used as main cargo oil pump have two main parts; a turbine and a centrifugal pump. The steam turbine consists of parts such as boiler, feed pump, condenser and turbine working together in a closed loop system.
What is a reciprocating cargo oil pump?
A reciprocating cargo oil pump is a steam or motor driven positive displacement pump; with a plunger moving within the pump cylinder. It is well known for its constant volume pulsating output at higher pressure. The pump takes in the fluid medium via a suction valve and discharge at a higher pressure through the discharge valve.
What are the different types of pumps in an oil tank?
Located in the pump room, the system comprises of a number of pumps including; eductors, steam reciprocating pumps, screw pumps and centrifugal pumps working as a cargo oil pump. But the most common arrangement is the one with centrifugal pump; driven by a steam turbine.
