Come and Visit Linkmarine For #1 Oil Discharge Monitor ODME UAE



If you're reading this, you're probably aware of what ODME stands for. But let's ask it anyway. Why do we need ODME? Can’t we just ban throwing oily mixture overboard and land it with a barge? This read will help you to know more about Oil Discharge Monitor ODME UAE.

What is ODME for?


Oil discharge monitoring equipment (ODME) measures the amount of oil in the ballast and slop water. The device has a GPS, data recording capabilities, an oil content metre, and a flow metre. A computer device will be able to enable the discharge to continue or halt it via a valve outside the deck based on data interpretation.

Important Parts Of ODME

  • An Oil content meter: The oil content metre is used to determine how much oil is present in the water that will be released overboard. This oil's concentration is measured in parts per million (PPM).
  • A computing unit: A calculating unit determines the amount of oil discharged in litres per nautical mile and the overall quantity, as well as the date and time.
  • A flow meter: At the discharge pipe, the flow rate of the oily water to be discharged is measured.
  • An overboard valve control system: When the permitted limit is reached, the auto control valve is positioned at overboard and must close and stop the discharge.

Operation Of ODME?

Let's look at an example: a 21.8000 DWT product tanker that recently discharged a 15000 MT oil cargo. This tanker was required to clean these tanks, which were carrying a total of 15000 MT of oil cargo. What's the best way to clean and decant the slope using ODME? Let's have a look at how the ODME operates:

Step 1: Set the total oil quantity in ODME

The amount of total oil we can discharge in the wash water has been set by Marpol. This limit applies to 1/30000 of the total load transported. So, 15000 m3 of cargo was carried in the tanks to be cleaned at 15 degrees Celsius.

Total oil can be discharged =500 litres

Then set the total oil limit as 500 litres in ODME

Step 2: Allow a minimum of 36 hours of settling time

The tanks will be cleaned, and the slops will be deposited in the slop tank. However, the oily water must settle for at least 36 hours before we can start pumping it out through ODME. This ensures that the oil has completely separated from the water at this point.

Step 3: Check the discharge conditions in Marpol Annex I, Reg 34

Other requirements pertaining to the vessel being enroute, minimum speed, and distance from nearest land must also be met.

Discharge Criteria:
  • The tanker should be more than 50 NM from the nearest land
  • The tanker should be en route
  • The tanker should not be within a special area
  • The instantaneous rate of discharge into the sea should not exceed 1/3000 (for new ships) of the total quantity of the particular cargo of which the residue formed a part

Step 4: Preparation condition before start ODME

  • Check the inlet and outlet valves for the flow meter are open
  • Check All valves are open and freshwater is accessible.
  • Make that the input and output valves on the sample line are open.
  • Make that the air supply for the pneumatic valves is turned on.
  • Make sure the cleaning solution is in the container.
  • Make sure the electricity is on.
  • Examine the sample pump shaft.

Step 5: Start the cargo pump in cycle mode
Step 6: Start overboard discharge

We can initiate the ODME to begin overboard discharge when all of the preceding processes have been completed and validated.

Step 7: Monitor during entire oil overboard discharge operation

Please keep in mind that if you reduce the pump speed to lessen the flow rate, the IRD will decrease as well.

Step 8: Stop the overboard discharge

The ODME will stop

By manually:
  • Reached the interface level
  • See some oil sheen on the sea surface
  • The rapid increase in PPM. Please check to make sure that the oil-water interface is still very far.
By automatically:
  • The total oil discharge exceeds limit
  • IRD exceeds 30L/NM

Step 9: Perform the cleaning cycle

Each time ODME is turned off, the Cleaning cycle for the ODME system must be started. You have two options for starting: automatic or manual.

Step 10: Close the system

We may seal all the valves and turn off the electricity after the ODME process is done. Please keep track of everything in a logbook.

Boiler Control System UAE - Safety & Risks

Image
What is a Boiler Control System on Ships? The Boiler Control System is intended for use in the marine sector to automate burners and combustion systems on any type of ship. On engine ships, firetube boilers are used as auxiliary boilers to deliver lesser amounts of low-pressure steam. The use of small-diameter tubes and a compact steam drum in the design of water tube boilers allow for the generation or production of steam at high temperatures and pressures. Risks Related to Boiler Control System The engine room of a ship is a complicated set of machinery and systems that is utilised to perform numerous tasks on board. The marine boiler is one such crucial piece of equipment that has been helping ships since the beginning of shipping. Initially, marine boilers were mostly used to operate a ship's propulsion system, which ran on steam (steam engine). The steam created by the boiler is now used in a wide range of engine room systems, including the heating of fuel for the main engine....

Best Waste Water Treatment on Ships From Evoqua UAE | Linkmarine

Wastewater generated onboard ships should be treated before being released overboard into the sea. Grey and black wastewater are the two types of wastewater, and their treatment can be done independently or with the same equipment to handle both grey and black wastewater. There are different modern forms of wastewater treatment equipment available, all of which are delivered as a complete unit ready to install in the engine room. Once upon, all wastewater was collected in a tank and pumped overboard if the ship is within a specified 12 miles from any coast, it will be pumped out to sea. To prevent pollution, international law now outlaws this practice, requiring wastewater to be treated to appropriate levels before being pushed over the edge. This read will help you to get more knowledge about wastewater treatment on ships.  Types of Wastewater in Ships There are mainly two types of wastewater. Grey Wastewater Black Wastewater Grey Wastewater Graywater contains wastewater from lav...

Explore the read about the hull stress monitoring system (HSMS) and the various technologies to measure it. Hull stress Monitoring System Hull stress monitoring system (HSMS) provides real-time information to the officers and masters on the ship about the motions and global stress experiences while navigating and during loading and unloading operations. The HSMS is an aid to the master. It doesn't replace his own responsibility or judgment. The HSMS includes various sensors, such as rosette gauges, long-base strain gauges, and trio-axial accelerometers to monitor hull girder deck stresses and localised stresses on side shell, cross-deck strip, bulkheads, and double bottom structure. Real-time data from these sensors are provided for urgent use and for the evaluation of the course and speed changes. Various Technologies To Measure Hull Stresses In Ships As a result, it's essential to collect a huge set of statistical data from which we may create empirical relationships that c...
