a) EGE tubes Soot blow is to be done normally once a day.

b) The officer on bridge watch should be consulted prior to the operation commencing, and the vessel’s course altered if necessary.

c) EGE tubes should be soot blown as a minimum 2 hours prior to arrival at port, US waters, and after departure from a port.

d) In case of steam soot blow system, before commencing soot blow, it is important to thoroughly drain the water in the system. After completion of soot blow, the steam inlet valve to be closed, and the drain valve to be opened.

e) When carrying out soot blow, it is important to increase ME load in order to achieve high EGE temperature which will significantly decrease the fouling of the EGE and ensure its cleanliness.

f) For condition monitoring, it is important to ensure that the in/out temperatures and in/out differential pressure of the EGE are logged daily in the Engine Room Logbook for assessing the extent of fouling.

g) Additionally, EGE should also be visually inspected at every suitable opportunity to ascertain its fouling condition.

a) EGE tubes manual cleaning by F.W or high-pressure air is to be carried out as per the PMS (approximately at three-month intervals or as per condition monitoring).

b) Cleaning Precautions:

• (i) Install a blank cover at the exhaust gas inlet from the M/E T/C to the EGE, so that the washing water does not flow out to the T/C side.
• (ii) Keep the drain cock of the M/E T/C casing open and check the drain.
• (iii) Make sure that the washing water discharge line to the soot collection tank is clear with free flow.
• (iv) Loose soot remains after washing, and there is the possibility that a large amount of heated soot may be released after initially starting M/E, so it should be carefully monitored.

a) Settling - Collected washing water in the soot collection tank needs to settle for about 24 hours.

b) Skimming - Solid soot particles on the surface of the wash-down water must be skimmed/collected before discharging.

c) Discharge – Wash water must not be discharged overboard. Refer EMS-05-02.

d) Disposal of solid soot particles – Disposed of to the shore reception facility. Refer EMS-05-02.

e) Recording:

• (i) Soot discharged to shore reception facility must be recorded in the Garbage record book.
• (ii) Soot water management to be recorded as per EMS 05-02.

a) Cleaning - Clean with compressed air as much as possible. If freshwater cleaning is required, contact PIC to discuss how to do it and how to treat cleaning water.

b) Collected Soot - Disposed to the shore reception facility.

c) Recording - Soot discharge to shore reception facility must be recorded in the Garbage record book.

Turbocharger washing shall be collected and transferred to the Sludge Tank to avoid contamination of the Bilge tank if transferred due to any reason.
