HI Tom,
I think I'm the guy whose name escaped you. No problem - it's not the first time ;-)

I posted a while ago that the belief you cannot run in brackish water is a long standing "old wives tale" about water makers. I said one should simply not exceed the fresh water flow rate of your membrane. My post went on to assert your membrane will even be happy running in the fresh water of, say, the US Great Lakes or up the Guadiana River between Portugal and Spain.

The Dessalator manual saying only to use it in "normal ocean water" (whatever that is) is obviously written that way because their equipment uses a "Green Zone" which is calibrated for "normal" ocean water and they do not want to address any other usage scenarios for legal protection.  It is similar to car makers eliminating gauges in favor of "Idiot lights". 

So, yes, you are totally correct in your theory that high pressures which would give a (TOO) high production rate is (definitely) harmful to the membranes. And that is easier to do in low salinity water if you are not monitoring the flow rate, but only looking at the "Green Zone".

If upping the pressure above 800 psi I would first make sure that the pressure vessel and the end cap seals are able to withstand the higher pressure.

Tom,

Filmtec states the following about the SW30 2540 membrane, "This membrane is rated for a maximum 700 gallons per day, we use it in our watermakers to produce actual 21 gallons per hour from standard seawater (35000 ppm). In brackish water, freshwater production will increase but you should not exceed 30 gallons per hour or 700 gallons per day."

So, I believe that if you turn the pressure down so that the flow rate does not exceed the rating for the sum of the flow rates of your membrane array, you'll be doing exactly what Filmtec states above.

Here are the flow rates of common SW30 membranes:

Re: A54 hawsehole and chain guide

Arno Luijten
 

Oliver,

If WASI supplied that chain it is not good news as they supply either AISI304 or AISI316L chain. That is not suitable for long term anchoring as the steel needs to be exposed to the air regularly to prevent crevice corrosion.

Cheers,

Re: A54 hawsehole and chain guide

Arno Luijten
 

Hi Thomas,

There was a reason I said cromox chain. There are many, many different qualities of SS. If you are at anchor for extended period of time some of those will suffer crevice corrosion because of oxygen deprivation. Cromox is resistant to this .... at a price.
Crevice corrosion will be barely noticeable until it breaks, not the nicest way find out.

Thanks Bill,
After I asked, I figured I’d man-up and search for myself. I found the exact page you posted.
I guess it’s safe to run a bit higher pressure. The WM will shut off if the pressure goes too high I believe......
Well this means that the float in the flow meter will disappear when the pressure is higher in the green zone (it does).

Hi Teun,

No, it’s only when we let out the full chain for whatever reason. So it’s very rare and only to minimise the chance of bungling it during business as usual. (That rarely happens anyway, even with galvanised chain). 

Hope that clarifies the use case.

Thomas,

 

Does this mean that every time you weigh anchor that somebody is guiding this device by hand in the right direction to evenly spread the anchor chain?

 

If so then I clearly have too many sails in the sail locker as it is completely full and was really a massive, massive head ache to get to the chain locker when the new (galvanized) chain bungled up. I never had the bungling up issue with the OEM SS chain and since I pushed a bunch of the galvanized chain all the way to the back it hasn’t happened since. It is rare, even in the South Pacific, that I use the last 30 meters of a 100 meter chain so pushing those 30 plus meters all the way back in the chain locker I believe prevents the bundle of chain getting too high in the front and thus getting tangled/bungled.

 

But your device looks what I need but then I also need: A) easily access to the chain locker as well as B) a pair of hands during departure.

Subject: [AmelYachtOwners] A54 hawsehole and chain guide

 

Hi all,

 

We recently end-to-ended our anchor chain and I found the pictured device useful to guide the chain nice and flat at the bottom of the chain locker.

 

It’s simply a piece of PVC pipe with a couple of small line to gutter the chain in various corners of the locker.

 

 

 

And when you don’t use it, it snaps happily on the hawsehole pipe for efficient storage. 

 

 

 

 

Best,

 

Thomas

Hello Scott,

In 2007, Amel used to buy SS chains from WASI GERMANY.

As an aside, does anyone know who makes the Amel oem stainless chain? It has a 5 stamped on it, if that helps?

Teun,

What you need is a big wallet and 100 meters of Cromox 10mm (made by Ketten Wålder, https://www.ketten-waelder.de/en/) 😂

Re: Oil Pressure Volvo D3 I - C

Actually the way it works at VP is that any significant change in the production of the eingine results in a new trailing character. Most Amels 54s have C because that is the one for wich production ran fairly long. The change form C to D was major as they changed the setup and position of all the ancillaries. Probably because they found out that putting the raw water pump on top of the alternator was not such a great idea. Also they changed the engine cover making it more silent. The base block itself has not changed that much. Fact is that Volvo is no longer using it in their cars since a few years making the production volume of this block much smaller.
The biggest change (as far as I can tell) between the "A" and "B" and the "C" version is the electronics got beefed up because of many failures with them.
The changes from "D" to "I" are fairly minor I believe.
I still think it's a good engine with very good characteristics. The fact you hear many complaints about it is because there a quite a few out there. It will treat you as you will treat it in most cases. It is still a fairly complex engine and you should treat it as such. Prompt preventive maintenance and clean diesel are the way to go.

Just my two cents...

Voker,
Can you send some more pictures of the assembly?  I'm curious to see how each piece fits together.

Problem solved:-)
The ship yard was able to take the swivel apart and to grind the plastic bearings a bit, so that they are turning now smoothly.
The start of the problem was that the previous owner had used mineral oil grease and this caused the plastic bearings to swell. Time over time the swivel starts to turn stiffer and stiffer until it bends the horns and finally blocks.
