How do I check my OWS 15ppm alarm?
Hold the OIL ALARM switch 33 pressed. OIL ALARM is issued in 2 seconds. OIL ALARM lamp 17 blinks and 15 PPM is displayed. At same time ALARM is raised in Engine Room.
How often must the accuracy of a 15 ppm bilge monitor be checked?
five years
The accuracy of 15 ppm bilge alarms is to be checked by calibration and testing of the equipment conducted by a manufacturer or persons authorized by the manufacturer and should be done at intervals not exceeding five years after its commissioning, or within the term specified in the manufacturer’s instructions.
What are the alarms for oily water separator?
A 15ppm Bilge Alarm is normally used in connection to a ship’s oil filtering equipment (also known as “bilge water separator”), monitoring the oil content of the separated/filtered water and stopping the discharge into the sea if the oil content exceeds 15ppm (parts per million).
What is oil content monitoring system?
An Oil content monitor is a device for real time sampling and measuring of the oil content in a moving stream of water.
What is an oily water separator OWS )? Explain?
An oily water separator (OWS) (marine) is a piece of equipment specific to the shipping or marine industry. It is used to separate oil and water mixtures into their separate components. This page refers exclusively to oily water separators aboard marine vessels.
What is the function of an oily water separator OWS?
As the name indicates, the function of oily water separator is to separate maximum amount of oil particles from the water to be discharged overboard from engine room or cargo hold bilges, oil tanks and oil-contaminated spaces.
Who should check and certify the accuracy of 15ppm bilge monitor?
The accuracy of 15 ppm bilge alarms is to be checked through the calibration and testing of the equipment, to be conducted by the manufacturer or by persons authorised by the manufacturer.
How does a oily water separator work?
Oil water separators are designed specifically to target oil based on the gravity difference between oil and water, allowing for heavier solids (sludge) to settle to the bottom while oil rises to the top, leaving additional wastewater in the middle layer.
How does an OWS work?
How do you monitor oil in water?
Oil in water monitors or oil in water analysers can be used to detect and measure oil content in water. On a vessel this can be known as the oil content monitor (OCM). An oil in water monitor can use a range of measurement technologies to suit different applications.
What precautions are taken during operation of an OWS?
Operating Procedure
- OWS overboard manual discharge valve is to be kept locked and keys are to be kept with the chief engineer.
- Open the desired bilge tank valve from which the oily water mixture is to be discharged from OWS.
- Open air if the control valves are air operated.
Which equipment that continuously monitors how much oil is in the water that is pumped out the discharge line of the OWS system?
Oil Content Monitor and Control Unit The ppm of oil is continuously monitored by Oil Content Monitor (OCM); if the ppm is high it will give an alarm and feed data to the control unit.
