Re: Looking for mentors - Engine cadet - First Trip on VLCC
Hello Possibly_water. That is an upsetting message but, sadly not uncommon. I'm afraid that these arseholes are an occupational hazard and I have met many. They come and go. Is the 1AE due off anytime soon? Is the chief aware of what is going on? What is the atmosphere/working relationship like amon...

Re: OSD60 temp. control slow response
Hello AboFaris. Do you mean the FO settling tank when you refer to the buffer tank? I ask because every ship I have been on, the FO separator will wobble (alarm and come off separation) when the settling tank is topped up even with heating on the bunker tank. The difference in temperature is too gre...

Re: Alfa Laval S936 Bowl leakage
I am not familiar with hearing the bowl close with a clang which may be the operating slide as the bowl closes on the polyamide seal (genuine parts?). I am not sure how far open the bowl is during stopped as it is a 'Flex' and uses the Centrishoot system and there is no sliding bowl bottom. Are ther...

Re: Alfa Laval S936 Bowl leakage
Hello apples 12345, nice report. As Atlantic says, check the speed (is speed sensor installed and enabled?). It seems an issue with closing water but there is evidence that the bowl has been closing. Is the 1.5 mm nozzle (part no. 545869 in the operating slide in my 946 manual) in place and not bloc...

Re: westfalia Purifier Problem
Why is there such a large range of pressure in the water supply, 3-10b? Does the hydrophore need recharging on the gas side (check the pressure at the schrader valve with the water pressure relieved)? There are four valves on a 0136 Unitrol: operating water open/close and operating water displacemen...

Re: Alfa Laval S846 HFO Separator problem
Check the function of PT4 and PT5. Is V5 passing? What is the flow through SV10? Check through all the parameters; has something changed like a timer setting? Run it in manual and see if the pressure will rise when you open SV10 with V4 closed.

Re: westfalia Purifier Problem
How old is this stuff? I haven't seen this PLC 100 for years. I would run the machine manually (without the automatic program) to test the separation and the ejection but it is unlikely that they are all defective. It must be something common to all three. "The water has good pressure" wha...

Re: westfalia Purifier Problem
Hello Eben 4E. Which control panel do you have? Are the separators all taking from the same water supply? Is it a main or a header tank? It sounds like a lack of operating water. Check the flow through the valve. What has happened i.e. when and how did this issue begin? Will it operate ok in manual?

Reduce the 'High flow rate', set the temperature to 98 deg.C and BP to 2.0b

Re: Alfa Laval S846 HFO Separator problem
Hello Chillmen. What is the back pressure reading? Which valve is flow adjust valve that you refer to? Is it a proper flow control valve (usually red plastic knob with a 'number of turns' type mechanical display) Is the feed pump controlled with a VFD? If so, turn down the frequency to slow down the...

Re: Alfa Laval S846 HFO Separator problem
Does it turn freely? Is everything tight especially the two lock rings? Got a good clean water supply? Correct temp? Test it by running it. If you don't want to get it dirty then run it on water manually to check the operation.

Re: Alfa Laval S846 HFO Separator problem
Hello chillmen, is your quote of my response to Namit4's issue of no drop in pressure on PT4 during the timer the same as what you are experiencing now? The feed staying on during discharge is a possible for this alarm. The 3-way valve V1 operates up and down, not rotary in my experience and I have ...

Re: Excessive Erosion on liner surface_ Wartsila 18V46
Hello mdjahirul. It looks more like corrosion. Need more information: How many hours on the liner? What is the condition of the piston/rings? What was the condition of the unit last time it was pulled? How do you hone the liners? Do you take regular PMI measurements? Are there any previous issues of...

Re: Alfa Laval S846 HFO Separator problem
So the Transducer - No Response alarm is no longer coming? Is it still discharging? Was PT1 Low part of the initial problem? What is the alarm limit for the feed (Pr15)? You can disable PT1 by setting Pr14 to 0.0b. If the pressure out of the pump is 2.5b then it is not low. PT1 is after the pump and...

Re: westfalia Purifier Problem
You need to confirm the pressure. If the panel (sensor) cannot read the correct pressure then it is likely to affect a lot of the programme. The list of PAL outlet (#44 alarm) is on this page near the top, have you been through that list of possibilities? It is unlikely to be the new sensor (is it a...
