1 / 8

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

A) To prevent system overheating

C) To increase bilge water flow rate

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

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

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

C) To reduce the volume of water processed

D) To pressurize the bilge water

3 / 8

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

C) It removes solid contaminants from the bilge water

D) It increases fuel efficiency

A) It cools the bilge water

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

4 / 8

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

B) It generates high pressure

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

A) It is easier to maintain

D) It minimizes power consumption

5 / 8

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

D) It prevents any oil from being separated

A) It improves the separation efficiency

B) It may overwhelm the system, reducing separation efficiency

C) It increases the oil content of the water

6 / 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

C) To reduce the temperature of the bilge water

D) To directly separate oil from bilge water

A) To increase the volume of bilge water

7 / 8

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

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

A) To prevent the system from overheating

C) To increase the oil concentration in the discharge

D) To reduce fuel consumption

8 / 8

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

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

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

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

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