1 / 8

Why is an oil content discharge monitor essential in an OWS system?

C) To increase bilge water flow rate

B) To verify that discharged water meets regulatory oil content limits

A) To prevent system overheating

D) To reduce overall vessel weight

2 / 8

What is the primary purpose of an oil content discharge monitor in an OWS system?

A) To adjust the temperature of the bilge water

C) To reduce the volume of water processed

B) To measure and ensure that oil content in discharged water meets the legal limit

D) To pressurize the bilge water

3 / 8

Which type of pump is most suitable for use with an Oily Water Bilge Separator (OWS) system, and why?

C) Submersible pump, as it is versatile for all fluid types

D) Reciprocating pump, as it reduces oil content in the bilge water

A) Centrifugal pump, as it provides high-speed flow

B) Positive displacement pump, as it provides a constant flow rate

4 / 8

Why is it essential to control the feed rate of bilge water to an OWS?

A) To prevent the system from overheating

D) To reduce fuel consumption

B) To maintain optimal separation by giving the system adequate time to process the mixture

C) To increase the oil concentration in the discharge

5 / 8

How does an excessive bilge water feed rate affect the performance of an OWS?

A) It improves the separation efficiency

B) It may overwhelm the system, reducing separation efficiency

C) It increases the oil content of the water

D) It prevents any oil from being separated

6 / 8

Why is a positive displacement pump preferred over a centrifugal pump in an OWS system?

A) It is easier to maintain

C) It maintains a constant flow, essential for effective separation

D) It minimizes power consumption

B) It generates high pressure

7 / 8

What is the purpose of a bilge holding tank in an OWS system?

B) To temporarily store bilge water before processing through the OWS

A) To increase the volume of bilge water

D) To directly separate oil from bilge water

C) To reduce the temperature of the bilge water

8 / 8

Why is it beneficial to use a bilge holding tank before the OWS?

D) It increases fuel efficiency

A) It cools the bilge water

B) It allows bilge water to be stored and processed under appropriate conditions

C) It removes solid contaminants from the bilge water
