Facet BWS

The FACET bilge water separator is used to process bilge water from Intermediate bilge water tank 15PS to Clean bilge water tank 18C or directly overboard via the Whitebox.

In normal operation the FACET will process from 15PS directly overboard via the Whitebox.

Before the FACET can be started to process bilge water overboard we have to ask permission from the on duty officer on the bridge. If we have permission from the on duty officer on the bridge we need a starting time and a starting position to enter in the appropriate log books.

Starting the FACET bilge water separator

·        1. Open the main overboard valve. (This valve is normally locked. The key is in the ECR).

·        2. Check if the suction valve of 15PS is open

·        3. Open the FACET main suction valve

·         4.Open the TOP technical water supply valve to the FACET.

·         5.Make sure the BOTTOM technical water supply valve is closed.

·         6.Open the technical water supply valve to the OCM

·         7.Check if the return valve to 15PS is open(in case of high ppm/recirculation)

·         8.Check if the Whitebox outlet valve is open

·         9.To start the FACET select the selector switch operation mode to MANUAL

After technical water supply solenoid valve will open to discharge any remaining oil out of the top of the FACET. When the FACET is full of clean water it will start processing.

·       10. Check the Whitebox is functioning properly

In order to process water from 15PS to 18C manifold valve number ③ needs to be changed over. Instead of going to the Whitebox water will be going to the Clean bilge water tank.

If you want to process water from intermediate bilge water tank 15PS to Clean bilge water tank 18C no permission from the bridge watch officer is required.

Before starting the FACET check if the inlet valve to 18C is open

Stopping the FACET bilge water separator

·         1.Switch the selector switch operation mode to “0”

·         2.Close the main suction valve leading to the Facet

·         3.Close the technical water supply valve to the FACET

·         4.Flush the FACET OCM for at least 30 seconds

·         5.Close the technical water supply valve to the OCM

·         6.Close and lock the overboard valve

·         7.Flush the Whiteox OCM for at least 30 seconds

·         8.Report the Whitebox data logger overboard counter to the ECR

9.When the overboard valve is closed the bridge needs to be called for a stop time and a stop position.
