Re: [Amel Yacht Owners] Battery Compartment Explosion

Colin - ex SV Island Pearl
 

I am no expert on this subject so won't speculate on any causes however will relay our experience with old batteries here too in case it saves someone else from going through a similar bad experience.

We purchased our boat early - at least 5 years ahead of actually being in a position to go cruising as we have one daughter still at home and we both still work. For this reason our boat is very lightly used, normally just week-ends etc., and therefore we did not want to replace our batteries (2011 lead acid batteries) until just before we commence cruising in April 2017..  ie replace at 6 years age due to light usage ... not a good idea so we discovered...

Earlier this year, when these batteries were 5 years old, I returned to the boat one day to find the under side of the mattress above the battery compartment very hot too touch. It was, in my view, far too hot to safely open the compartment so I immediately disconnected the solar charger feed in to the batteries, switched off the battery switches and let it all cool down till the next day. (By the way we are in a marina berth but have 540w solar through a Tracer MPPT controller so do not typically plug the chargers into shore power, other than for occasional use of washer or other power hungry items).

Late the next day when I opened the compartment (still pretty warm!) I discovered the compartment had about 1 inch of battery water sitting in it and some pretty warm batteries. Also the lovely Blue Amel sign on the starboard side (where the battery compartment vent exits the boat) was showing signs of heat cracks through the once beautiful Amel sign paint, so clearly that vent was working well and allowing the heat to escape.

So our lesson learnt, and hopefully others may now consider this safety issue too, is that we will in future always change our batteries out absolutely no later than 4 years regardless of how little use they have had, or how good their condition appears.

Batteries exploding is more common than you think. I am not sure, but would guess that internal shorts in some of the batteries caused your solar/wind controllers to overcharge and cook the batteries until the sealed batteries popped open, buldged, or exploded.

This is the primary reason that chargers and/or solar and wind controllers without temperature sensors should not be left unsupervised. Temperature sensors turn off the charger when the temperature increases. I know of about 6 boats that had this problem. Two of them were Amels, one SM and one 54. They each have new owners now, so I will not mention the boat names.

Your battery compartment is vented to the outside, and I am reasonably sure that venting was not the issue. You really do not want to vent that battery compartment inside the boat. Read up on why.

I am fairly certain that your batteries were at the limit of their life (4 years) and surely had internal shorts causing the overcharging, bulging, and explosion.

The explosion was quite se vere and apparently set off my smoke detector which everyone in the yard heard. There was no fire. Oddly no one claims they heard the explosion itself, as it may have happened before the contractors started to come in for work. It blew the lid completely off of the passageway berth and into the ceiling, jamming it between the wall of the aft closet and the wall near the nav station closet.

I do not want to even speculate what would have happened if someone had been sleeping on the berth. I had some parts and tools sitting on the berth cushion and they were either shredded, melted, or survived depending on the material. It was a scary situation.

I am working with my insurance company and they hired a local surveyor to assess the situation. They, as I do, want to know the reason for the explosion. Beyond the damage to the compartment lid/berth and the surrounding woodwork, here are the facts:

  • At least 2 of the AGM batteries had been breached with cracks in the tops. None of the VRLA valves had popped.
  • A few of the batteries were bulged out at the sides. Not clear if that happened initially or as a result of the explosion. Ultimately about half of the 12 on the 24-volt side were "bad."
  • My shore power connections were off. The only charging source would have been wind and solar. Both of tho se systems have been working correctly for a long time, and early in the morning there was no wind and not much sun. We do not think it was an overcharge issue. I have multiple monitoring systems including the Xantrex that came with the boat, plus a Maretron monitor and Blue Sea meters. All were nominal when I left the boat before the explosion. Voltage was about 27.5 and there was a small load of maybe 3 or 4 amps DC, easily absorbed with the solar panels.
  • The batteries are a little over 4 years old and came with the boat. I have never had a problem with them, and the charging systems have never pushed above 28 volts.
  • The battery setup was reworked last winter by a very good contractor here in the yard. They added fuses to all the loads, and it has worked very well for months now. I find it hard to believe that there was no primary battery fusing on the boat at all, but that is s till another topic for review. However, the explosion would not have been related to current flow and hence the fusing was not an issue one way or the other.
  • I have 12 Intimidator AGM batteries in the battery area with a 12V starting battery.
  • Testing them after the accident revealed about half of them to be unserviceable (either electrically or physically).

It is clear to the investigators that the explosion was the result of hydrogen gas buildup in the battery compartment. The problem they observed is that (while there is a vent at the forward part of the battery compartment, Amel seals the compartment completely). Normally the vent is OK, as any residual hydrogen will escape out the vent. But the Amel setup prevents any makeup air from entering the compartment. Normally AGM batteries do not vent externally, as the hydrogen sulfide normally released in a flooded battery is actually recombined in an AGM setup. There are valves in a VRLA battery, which are supposed to open if the internal pressure gets too high. However, if the casing is breached, gasses will release immediately, which is what happened here. What no one knows yet is why the batteries cracked open. The bottom line is that the vent could not release the gas fast enough, and the hydrogen gas exploded as it built up in the sealed compartment.

I am going to modify the configuration by adding ventilation to the front of the battery compartment. I am also going to install 13 new Lifeline batteries (12 31-XT and 1 31T battery for starting). Good quality batteries with a modified install should pre vent a recurrence. What a mess.................

All I can say is thank goodness no one was hurt.

Re: [Amel Yacht Owners] Dodger glass thickness

We used a flexible product from Sikaflex. But, 3 of the 4 pieces on a SM are also screwed. I think it will take a lot of force to crack 10mm plexiglass.

Battery Compartment Explosion

James Wendell <ms42phantom54@...>
 

I am not sure if anyone has ever experienced what just happened to me, but I think it is important info for everyone out there. My battery compartment exploded early yesterday morning. No one is certain exactly what happened, and no one who has investigated the accident has ever seen this occur. I am still up on the hard in Annapolis trying to get my new engine installation completed - that was a subject of a previous thread, and I will update everyone who followed that thread separately once I get my new engine running.

The explosion was quite severe and apparently set off my smoke detector which everyone in the yard heard. There was no fire. Oddly no one claims they heard the explosion itself, as it may have happened before the contractors started to come in for work. It blew the lid completely off of the passageway berth and into the ceiling, jamming it between the wall of the aft closet and the wall near the nav station closet. Fortunately no one was on the boat at the time, but if someone had been in the passageway between the main saloon and the aft cabin, they would have been seriously injured or even killed. I do not want to even speculate what would have happened if someone had been sleeping on the berth. I had some parts and tools sitting on the berth cushion and they were either shredded, melted, or survived depending on the material. It was a scary situation.

I am working with my insurance company and they hired a local surveyor to assess the situation. They, as I do, want to know the reason for the explosion. Beyond the damage to the compartment lid/berth and the surrounding woodwork, here are the facts:

  • At least 2 of the AGM batteries had been breached with cracks in the tops. None of the VRLA valves had popped.
  • A few of the batteries were bulged out at the sides. Not clear if that happened initially or as a result of the explosion. Ultimately about half of the 12 on the 24-volt side were "bad."
  • My shore power connections were off. The only charging source would have been wind and solar. Both of those systems have been working correctly for a long time, and early in the morning there was no wind and not much sun. We do not think it was an overcharge issue. I have multiple monitoring systems including the Xantrex that came with the boat, plus a Maretron monitor and Blue Sea meters. All were nominal when I left the boat before the explosion. Voltage was about 27.5 and there was a small load of maybe 3 or 4 amps DC, easily absorbed with the solar panels.
  • The batteries are a little over 4 years old and came with the boat. I have never had a problem with them, and the charging systems have never pushed above 28 volts.
  • The battery setup was reworked last winter by a very good contractor here in the yard. They added fuses to all the loads, and it has worked very well for months now. I find it hard to believe that there was no primary battery fusing on the boat at all, but that is still another topic for review. However, the explosion would not have been related to current flow and hence the fusing was not an issue one way or the other.
  • I have 12 Intimidator AGM batteries in the battery area with a 12V starting battery.
  • Testing them after the accident revealed about half of them to be unserviceable (either electrically or physically).

It is clear to the investigators that the explosion was the result of hydrogen gas buildup in the battery compartment. The problem they observed is that (while there is a vent at the forward part of the battery compartment, Amel seals the compartment completely). Normally the vent is OK, as any residual hydrogen will escape out the vent. But the Amel setup prevents any makeup air from entering the compartment. Normally AGM batteries do not vent externally, as the hydrogen sulfide normally released in a flooded battery is actually recombined in an AGM setup. There are valves in a VRLA battery, which are supposed to open if the internal pressure gets too high. However, if the casing is breached, gasses will release immediately, which is what happened here. What no one knows yet is why the batteries cracked open. The bottom line is that the vent could not release the gas fast enough, and the hydrogen gas exploded as it built up in the sealed compartment.

I am going to modify the configuration by adding ventilation to the front of the battery compartment. I am also going to install 13 new Lifeline batteries (12 31-XT and 1 31T battery for starting). Good quality batteries with a modified install should prevent a recurrence. What a mess.................

All I can say is thank goodness no one was hurt.

Re: [Amel Yacht Owners] Dodger glass thickness

jwagam@...
 

I just had all new dodger Windows cut from polycarbonate. Bill, you mentioned glueing them in. I assume you would mean using 5000 for this? I am on the fence on whether to go that route or use Silicon that can allow more flex. I was concerned that the window might crack as the dodger flexed. Thoughts?

Re: [Amel Yacht Owners] Re: bow thruster service. Problem

Hi Jim,
If everything with the shaft and motor looked OK, it almost had to be coming out at an angle rather than straight down???  Had the shaft and splines cleared the motor when it jammed?
I'd sure like to know what happened.

Thank you, Alexandre & Bill.

A picture is worth a thousand words, thanks, Alexandre!

I still am baffled by my first question. Upon easily separating the thruster shaft from the clean and well-greased motor, if let go the whole foot would either fall out the bottom of the boat or down to the temporary retaining hose clamp (which I installed about 2" from the very top of the shaft). Mine didn't. It stopped before reaching the hose clamp, with 4" of shaft still sticking up. much force, simultaneous from me above and the diver below, was required to get the shaft to go the remaining 4" to come out the bottom of the boat. I am worried that during re-assembly the shaft will again become stuck, leaving the tape between the special tool and the shaft underwater for an extended time.

Hi JP.  I would like to have that setup, but I have two issues:

On Kristy (SM243) the anchor wash pump is supplied with SW from a thru-hull inboard of the forward head (in the "hallway" between the head and hanging locker).  That would mean running a new hose from the FW tank through the bulkhead.

If that's not daunting enough, I have the 60 l/h watermaker, so I don't have enough capacity to justify washing the boat and chain with FW.

Too bad, here in the ABCs...there is constant accumulation of dust from the dry islands and has been a plume of dust from the Sahara adding to the problem since I arrived.  It has only sprinkled a few times in a month which turns the dust to mud.  I've been washing down w SW every few days to keep the cockpit and down below as dirt free as possible.  Even if I had the FW wash down I don't think I'd like to make water in the bay as there are no pump out facilities and I regularly smell black water being dumped.

If my Watermaker dies I will seriously consider replacing it with the duo.

Re: [Amel Yacht Owners] Re: bow thruster service. Problem

Alexandre Uster von Baar
 

I am a visual person myself, so try to illustrate what Bill, Gary, etc. have describe.

The problem of the 1st question doesn’t make sense to me… the shaft has the same size… going through a seal, so why should there be resistance?

Are you sure there was nothing in the water to block it?
Did you lower it straight down? not at an angle?

Unless Bill says otherwise, put lots of grease like on picture:
http://nikimat.com/bow_thruster_overhaul/bow_thruster_overhaul_76.jpg
This will help water getting in.

Good luck, please keep us posted of what you find…

Re: [Amel Yacht Owners] Re: bow thruster service. Problem

Jim Anderson
 

Thank you, Alexandre & Bill. Two of my three questions are now answered: It is normal to have to trim the 2 seals on the trunk, and my prop wont come off because the 6 nylon screws secure it to a hub and one must pull the pin out of the hub to remove it and expose the prop shaft lip seal. A picture is worth a thousand words, thanks, Alexandre!

I still am baffled by my first question. Upon easily separating the thruster shaft from the clean and well-greased motor, if let go the whole foot would either fall out the bottom of the boat or down to the temporary retaining hose clamp (which I installed about 2" from the very top of the shaft). Mine didn't. It stopped before reaching the hose clamp, with 4" of shaft still sticking up. much force, simultaneous from me above and the diver below, was required to get the shaft to go the remaining 4" to come out the bottom of the boat. I am worried that during re-assembly the shaft will again become stuck, leaving the tape between the special tool and the shaft underwater for an extended time.

Thanks very much for your help,

Jim

Re: 24V Watermaker

HI  Barry,
Regarding your comment when you said  "This does not make sense!  Why would you deplete your stored energy in your batteries to run a 24 volt motor on your water maker."  The answer is that I would not.  Please re-read my post where I say " It would be great to be able to make water while motoring or with solar"  In neither situation would my batteries necessarily be depleted.  I have considerable excess solar capacity during the day.  There is an excess of amp hours available because my solar system commonly tops up my house bank (SM Redline) by about noon.  Following this, measured unused capacity from the solar panels is substantial--equaling or exceeding 10 amps at 27+V (my solar capacity is pretty high) .   Also, like most Amel owners I have a high capacity (stock) alternator on my engine.  Its capacity is underutilized when motoring for extended periods because, again, the batteries are topped off drawing only a few amps and only 10 amps or so are used for refridge, autopilot and LED lighting, etc.  No question, the 220 AC Dessalator is very good, and you are quite right, I would not trade it for the 24V only system that you are complaining about, but the capacity to make fresh water with both 24 and 220 is desirable for some of us and need not be at the expense of depleting batteries (and running the generator to charge them back up).
Cheers,
Bob, KAIMI SM429

Re: [Amel Yacht Owners] Re: Anchor Wash Pump

Hi JP.  I would like to have that setup, but I have two issues:

On Kristy (SM243) the anchor wash pump is supplied with SW from a thru-hull inboard of the forward head (in the "hallway" between the head and hanging locker).  That would mean running a new hose from the FW tank through the bulkhead.

If that's not daunting enough, I have the 60 l/h watermaker, so I don't have enough capacity to justify washing the boat and chain with FW.

Too bad, here in the ABCs...there is constant accumulation of dust from the dry islands and has been a plume of dust from the Sahara adding to the problem since I arrived.  It has only sprinkled a few times in a month which turns the dust to mud.  I've been washing down w SW every few days to keep the cockpit and down below as dirt free as possible.  Even if I had the FW wash down I don't think I'd like to make water in the bay as there are no pump out facilities and I regularly smell black water being dumped.

If my Watermaker dies I will seriously consider replacing it with the duo.

Re: [Amel Yacht Owners] Re: 24V Watermaker

Bill & Judy Rouse <yahoogroups@...>
 

Barry & Robyn,

Those Amel owners that have these Dessalator DUO systems normally run the 24VDC system when motoring.

I agree that I would not change from the 160 liter to the DUO because when at anchor, and even with alternate charging systems like solar panels, you will find at least 3 hours a week to run the generator. And, 3 hours of the 160 liter produces all of the water that 2 people will use in a week including showers, washing dishes and clothes washing 2-3 loads. We average about 55 liters a day including everything. If you run the generator for 3 hours you can certainly top-off your batteries once a week to 100%. 

We traditionally have done this on Thursdays: Run the Generator, Wash 2-3 loads of clothes, charge the batteries, make water. We have to be careful not to use any other electrical device such as the Microwave or Hair Dryer when doing this. Also. we will ONLY wash clothes with heated water and run the water heater in the last hour because we try not to exceed the capacity of the generator. By the last hour the 100 amp 24VDC battery charger is only pulling a few amps. 
  • Dessalator 160 pulls 15 amps
  • Water heater about 3 amps
  • Clothes washer without hot water setting about 2 amps, but 10 amps with hot water. 
  • The 100 amp charger will pull about 9 amps with the batteries at 75-80%. 
  • The top capacity of the generator is 30 amps. I use 27 amps as my top.
It helps to have an amp meter installed to monitor this.

To me, a prejudiced and very happy 160 liter owner, the best and only solution is the 160 Liter Dessalator water maker. If I did not own a capable generator, I might sing a different tune.

Why would you deplete your stored energy in your batteries to run a 24 volt motor on your water maker. If you managed your water storage enough, you would be utilizing your genset output each day to top up your water using your 110/240VAC motor while replenishing your battery capacity at the same time.

I have a 24VDC motor on my Dessalator and I would gladly swap it for a 240VAC motor. Ridiculous as it may sound, the amperage used to run a 24VDC motor has to be replenished by running the Genset to keep the batteries topped up. Needless to say, I run my Genset while making water and charging my batteries at the same time.

Re: [Amel Yacht Owners] Re: bow thruster service. Problem

Bill & Judy Rouse <yahoogroups@...>
 

Jim,

You did not say that you looked up at the bottom of the motor.  It probably looks like this: https://groups.yahoo.com/neo/groups/amelyachtowners/photos/albums/1587075684/lightbox/549533960?orderBy=ordinal&sortOrder=asc&photoFilter=ALL#zax/549533960

As the cast iron electric motor housing oxidizes because of salt water, the rust causes a reduction in size of the tube connection, freezing the tube to the motor housing. Take a camera and point it up at the bottom of the motor and see if you get something similar to the above.

Clean the oxidation very well and use wet dry sand paper on the inside wall. Then grease this entire area with waterproof grease...also same grease for the end of the tube that inserts into the motor housing.

Take a look at Alex's photos on a rebuild of the bow thruster at http://nikimat.com/bow_thruster_overhaul.html
You will see that the bow thruster propeller shaft is behind the white Delrin propeller hub.

You need to slightly trim the external (2) neoprene seals to fit.

Hope this helps.

Perfect timing on this topic for me. Thanks in advance for any help with the following questions. Please forgive me for demonstrating ineptitude as I chime in with a few questions:

 

1. When doing the in-the-water service today on SM384, as per Gary Silver’s instructions & Bill Rouse’s additional notes, after removing the four hex-head screws that secure the Thruster Shaft Housing to the Motor, the shaft would not drop all the way down and out the bottom of the boat. It stopped a good 2” above the “stopper” hose clamp. After installing the Amel Special Tool initially I could lift the shaft up and down but after trying to ram it downwards it stuck and wouldn’t budge up or down. I had to hire a diver. After much pulling and wiggling the diver finally got the shaft to come out. Upon inspection of the foot, shaft and the diver’s inspection of the Thruster Trunk nothing looked unusual. Any ideas what might have caused this?

I am hoping I won’t encounter the same problem with the shaft getting stuck when trying to put it back in tomorrow.

 

2. The diameter of the two neoprene seals on the Thruster Foot is larger than the width of the foot on one side and would over-hang on one side, except the excess was trimmed off with a razor knife. (Photo posted at: https://groups.yahoo.com/neo/groups/amelyachtowners/photos/albums/1196149903

The Amel-supplied replacements are identical and will need have the over-hang trimmed off too if they are not to over-hang.  Is this normal? (Last service, seals in photo done by Amel Martinique.)

 

3. Where is the Prop Shaft Lip Seal? Is it in the hub of the propeller, flush with the 6 nylon screws that hold the prop on, or is it behind the prop in the foot? I removed the 6 nylon screws from the prop but it will not come off.  The seal in the hub of the prop, flush with the nylon screws, is smaller than the Amel-supplied prop shaft seal so I presume the lip seal is in the trunk behind the prop. If so, any suggestions on how to get the prop off with the 6 nylon screws removed?


Again, thanks for any help and please forgive me for demonstrating my ignorance.

Good morning Jim,

1) I did 3 times the bow thruster overall and it never happened to me, unless I am not understanding the question…
You did not keep the stopper to make the Thruster shaft going through the seal did you?

Here are pictures I took, it if helps: http://nikimat.com/bow_thruster_overhaul.html


2) Being cut is normal, I think a slightly better job could have been done cutting the foam.

3) The prop shaft lip seal in under the propeller hub, here is the picture:
http://nikimat.com/bow_thruster_overhaul/bow_thruster_overhaul_22.jpg

You will need to be “VERY” careful using 3 tiny screw to pull it out. You don’t want to damage the food of the bow thruster.
Look at my pictures. I think it will make sense.

Sincerely, Alexandre

Re: 24V Watermaker

seagasm@...
 

This does not make sense!

Why would you deplete your stored energy in your batteries to run a 24 volt motor on your water maker. If you managed your water storage enough, you would be utilizing your genset output each day to top up your water using your 110/240VAC motor while replenishing your battery capacity at the same time.

I have a 24VDC motor on my Dessalator and I would gladly swap it for a 240VAC motor. Ridiculous as it may sound, the amperage used to run a 24VDC motor has to be replenished by running the Genset to keep the batteries topped up. Needless to say, I run my Genset while making water and charging my batteries at the same time.

Hi Bob,

Noa (SM2K #436) has the same setup as Elise, dessalator duo 60. The hp pump is driven via belt, either by 220V AC motor or by 24V DC motor, a compact and reliable setup. We use 24V DC when under motor, AC when running the genset. Dessalator specofies the 24V motor with 550W/18A, a bit more when starting. A dessalator 160 has a more powerful or faster running hp pump and the pump is driven directly by the AC motor, so, beside connecting problems, you´ll need a bigger 24V DC motor. The AC motor of the 160 dessalator is 2,2KW, so a DC motor will draw around 90+A, a bit more when starting. Quite substantial amount and difficult to get out of solar or wind power. To my knowledge dessalator doesn´t sell converting kits for the 160, maybe due to the data mentioned above.

Regards,
Walter (Noa, SM2K #436)
