Re: Dirty/brown/orange colour cooling water

Apologies Big Pete, I missed your post before. Water raises/lowers with startup/shutdown. I hope this will satisfy your curiosity Merlyn and allow you to move back from the edge of your seat :wink: As far as I can find out we do not have a smokemeter on board, so unfortunately I have not had the ple...

Re: Cat 3508 JW pressure issues

Have you tried when the unit is running to crack the bleeds around the engine to see if any air is present?

Is it possible to observe water level any rise or fall in header tank during running?

Re: Dirty/brown/orange colour cooling water

TDC I have read about a very similar issue somewhere else. This may/may not have been your post. We typically use maxiguard as well but due to the colour of the water it is impossible to accuratly add the correct amount of treatment to the system. I agree that it has to be something to do with the ...

Re: Dirty/brown/orange colour cooling water

Ah Merlyn. I did have a giggle reading that and yet still very useful information/tutorial. Just like an MOT emission check. (Anyone not from UK. An MOT is a test all vehicles between 3 and 40 years old must carry out. Essentially checked cars are not dangerous and systems work correctly for the roa...

Re: Dirty/brown/orange colour cooling water

I know this may be out there but has it been determined that the corrosion is not being generated by electrolysis? Was the alternator overhauled at the same time? If so were the ground straps for the alternator and the engine properly reconnected and any sacrificial anodes in the cooling system rep...

Re: Dirty/brown/orange colour cooling water

Here is me making assumptions. Oops! When you said 4/5 gas detector I thought you meant one of those meters you use for confined spaces. Where detecting HC was done by using the LEL function. My understanding of these meters is all classroom based as the company policy is no crew are allowed to ente...

Re: Dirty/brown/orange colour cooling water

Great idea with gas detector. Have you done this yourself before? I believe so yes, there was two guys present from the outfit but it was always the same two. The overhaul company are arguing they did everything right and we did something to cause the problem. Typical blame game. At least the politi...

Re: Dirty/brown/orange colour cooling water

Vessel was built in '03. I haven't found reference to the auxiliaries manufacture date. Yes, you are correct. Bottom end, top end, new turbo, LO cooler, air cooler plates and all new 6 heads (well 12 new heads as they have all been replaced). I may be missing a few bits as I wasn't on board when thi...

Re: Dirty/brown/orange colour cooling water

Hi Merlyn, We have already checked the stats are operating correctly and check the calibration of FW temp probe using the same water bath, all okay. I think this giant kettle thing you call i think is what I would call water bath. Sounds similar at least. When you say boil up. Do you mean check when...

Re: Dirty/brown/orange colour cooling water

According to manual the operating temperature should be between 75 and 90deg C. Due to constant flushing of system. No coolant treatment is added. Also the system we are supplied with requires a colour identification change to adjust to correct amount of additive which due to sludgy water is impossi...

Re: Dirty/brown/orange colour cooling water

Update: Engines are kept at roughly 60-70deg C and run between 74 and 78 degC When starting the units throw out some water and when warming up there is bubbling in the header tank. Once warm and on load there is no bubbling. The back to back crew did not flush the auxilliary and upon our return the ...

Re: 3D Printing Spare Parts

Concept of the idea of having a few raw materials than can cover various parts is great. I suspect most of us see the benefits of such a device on a vessel but also many limitations both politically and in practice. One major draw back I see is why would a manufacturer provide drawing to create such...

Re: 220V Insulation monitor, Low resistance/Fault from non earth TVs

Hi Big Pete, Happy new year to you to! Interesting read. Got some boys coming down next crew-change to install isolating transformer in all cabins. The idea about the signal cable screening being connected to the earth/neutral is a good idea. We also have a fault with our vsat that provides the tv s...

Dirty/brown/orange colour cooling water

Hello all, We have two auxilliarys that before drydock and full overhaul were filled with distilled water and unitor cooling water treatment. Post overhaul both have the same problem. Post major overhaul we are now using hard shore water. Since the overhaul almost immediately water has turned dirty/...
