How does an ODME work?

ODME computing unit gets the flow rate from flow meter. A small sample line goes from the main line, pass through the flow meter and goes back to the main line. Flow meter calculates the flow in m3/Hr and gives this value to the computing unit through a signal cable.

What is ODME test?

O.D.M.E is Oil Discharge Monitoring Equipment which is used to check and monitor oil is discharged follow related rule ( MARPOL 73/78 ) when a tanker discharges the sea water from the slop tank where sea water used to clean the tanker after unloading the cargo to be prepared to ship other kind of cargo has been stored.

What are the Odmcs oil discharge monitoring and control system regulations?

Therefore, Oil Discharge monitoring and control system (ODMCS) is used to prevent the pollution of ocean by oil due to the discharge from ballast and bilge spaces. The system must have provision to work in manual operating mode if the auto system is not working.

What is ODMC?

Meaning. ODMC. Oil Discharge Monitoring and Control (system)

What is a slop tank?

Slop tanks are present onboard tanker to store oily water mixture from cargo tank washing. The number of slop tanks depends on the Dead weight Tonnage (DWT) of the vessel. Sludge tank. Located in engine room, this tank is used to store sludge produced after treating fuel or lube oil through purifiers.

How does oil content meter work?

The oil content meter will sound an alarm if the liquid leaving the system has an unsatisfactory amount of oil in the mixture. The OCM uses light beams to determine how oily the water in the system is. The system will then gauge the oil concentration based on a light intensity meter.

What is decanting in tankers?

Decanting is a process to separate mixtures. Decanting is just allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity. This process can be slow and tedious without the aid of a centrifuge.

What is the purpose of ODME?

Oil discharge monitoring equipment (ODME) is based on a measurement of oil content in the ballast and slop water, to measure conformance with regulations. The apparatus is equipped with a GPS, data recording functionality, an oil content meter and a flow meter.

What is the function of slop tank?

Slop tanks are present onboard tanker to store oily water mixture from cargo tank washing. The number of slop tanks depends on the Dead weight Tonnage (DWT) of the vessel. Located in engine room, this tank is used to store sludge produced after treating fuel or lube oil through purifiers.

What is a double bottom tank?

Double bottom means watertight protective spaces that do not carry any oil and which separate the bottom of tanks that hold any oil within the cargo tank length from the outer skin of the vessel.

What is the use of ODME?

What is the ODME principle of oil discharge?

The ODME principle is based on a measurement of oil content in the ballast water, which is held up against the regulations and requirements. By data interpretation of an automated process, either allows or prevents discharge of ballast water.

What do you need to know about ODME systems?

ODME systems also have an analyzing unit that contains the Oil content meter, a fresh water valve for cleaning purposes, and a pressure transmitter that monitors the sample flow through the measuring cell. ^ “VAFInstruments | Home of VAF Instruments | Products | Oil Discharge Monitoring Equipment”. www.vaf.nl.

How does a sample pump work in an ODME?

This job is done by a sample pump. Sample pump will take the sample from the discharge line before the discharge valves. This sample is sent to the analysing unit for measuring the oil content and then sent back into the same discharge line. This pump is protected by a pressure sensor is fitted inside the analysing unit.

Where does the flow rate come from in an ODME?

ODME computing unit gets the flow rate from flow meter. A small sample line goes from the main line, pass through the flow meter and goes back to the main line. Flow meter calculates the flow in m3/Hr and gives this value to the computing unit through a signal cable.
