Play d’eau’s holiday technical issues

8 Comments

The gearbox oil leak throws oil out of the flywheel housing

Play d’eau has been brilliant and had very few engineering problems over the years. Maybe it’s a sign of her age (she’s 13 now), but we’ve had a few coming to the surface, recently.

Technical Log

So here’s a list of issues from our Tech Log which remain outstanding, together with ones we solved during the holiday.

Stabilisers, port fin – RESOLVED

The stabiliser ram seal and actuator plate seal both failed. Brian George of Golden Arrow drove from the UK to La Rochelle and corrected the faults.

Gearbox, starboard engine – NOT RESOLVED

Gearbox oil started to weep past the shaft seal into the flywheel housing and be thrown out of an inspection hole in 2014.

MDS Marine of Hamble replaced the shaft seal in late 2014, but the issue reappeared soon thereafter and again during this holiday. Oil appears to be thrown when operating above approx 1300 rpm (WOT = 2,600 rpm).

An associated problem is the tacho sensor, located within the flywheel housing, which has had gearbox oil thrown on it causing it to display erroneous readings at low rpm. It needs cleaning after the seal has been replaced.

Since MDS cannot attend for some time, an engineer from MIT Group, the main UK TwinDisc gearbox distributors, will fly to Play d’eau this coming Thursday and Friday to effect repairs. I will report in more detail later.

Alternators – NOT RESOLVED

Given unusual starboard engine instrument readings including low voltage whilst underway, action to investigate and correct will be,

  • having not be touched for 13 years, both will be rebuilt
  • having been installed in April 2006, all will be replaced

Note that the battery charger (new Mastervolt in 2013) checks OK.

Electronics – NOT RESOLVED

Ever since the new electronics were installed, we’ve suffered endless problems with the Furuno SC50 Satellite Compass and various NMEA sentences either failing to be sent or received.

Robin of RES Electronics (Guernsey) has been a great help in:

  • Replacing all three failed aerials in the satellite compass (warranty claim)
  • Changing some of the wiring where it was incorrect
  • Changing an NMEA converter to a high speed version

The remaining issues are,

  • ‘Heading missing’ on the Furuno NN3D when configured to the Satellite Compass for the heading source. Average 2 warnings per cruise leg
  • ‘Heading missing’ on the Furuno NN3D when confiugred to the Furuno PG500 fluxgate compass for the heading source. Average 1 warning per every other cruise leg
  • ‘Aborting’ and ‘Output Error’ warnings on the Furuno SC50 satellite compass. No 3 GPS aerial fails at least once a week. Is the satellite compass ever going to work reliably?
  • Navtex fails to read incoming messages when we continued south on holiday, but jumped back into action when north of Camaret

There has been an additional fault with the AC Services panel:

  • Starboard bus, shore power selected, current indicator gives wild readings for many minutes before it settles down. This may be a faulty sensor coil

Robin will attend to the above later in the year after the work on the alternators and batteries has been concluded, as above.

Salt water pump – NOT RESOLVED

The Headhunter XRS-124 that provides salt water around the boat has failed. Replacement on order.

Air Conditioning – NOT RESOLVED

The ‘pump trigger circuit board’ which controls water pump activation for air conditioning in the master cabin has failed. Replacement on order.

Apart from the above, everything is working well.

Exterminating bugs

Bugs – the bane of Play d’eau’s new Pilot House electronics. Can we really exterminate them?

I remember seeing mother-in-law size cockroaches in Delhi years ago in my flying days. There’d been a flying ant swarm and cockroaches, led by these five inch monsters with their armour plated backs, had come out with their armies to hoover a three Michelin star dinner.

In the airport terminal, some local lads were playing football with them but despite severe kicking and smacking against walls, these monster cockroaches just picked themselves up and carried on scurrying about searching for ants as though nothing had happened. They refused to be exterminated.

We now had a monster somewhere in the electrickery on Play d’eau.

Andy Craig of MEI

Andy Craig of MEI had come to Beaucette Marina on 1st May 2013 and resolved all our electronic woes – or so we all thought.

A few days later, a friend had come from the UK to see us, and in the middle of demonstrating (code for showing off!) our new pilot house equipment, the dreaded ‘Heading Data Missing’ alarm on the nn3d re-appeared with the associated ‘Steering Compass Missing’ warning on the Simrad autopilot, activating every possible audible alarm from the Chart Plotter, Radar, Instruments, and this time, from the Satellite Compass as well which also displayed an ‘Aborting’ message.

Arrrgh! An unknown mother-in-law cockroach had crawled out to mock us.

After re-booting the satellite compass many times, I called Andy of MEI. Having listened to my woes, Andy’s gentle voice came back with, ‘You won’t believe this, Piers. We’ve just had a Tech Bulletin from Furuno advising us there’s a potential fault in the GPS aerials they use in their satellite compass. From what you’ve said, the GPS1 aerial has failed which could have been the source of all the original problems.’

Robin of RES (Guernsey)

In the moments that followed, Andy spoke with the warranty desk at Furuno which immediately accepted the warranty claim, arranged for a spare aerial to be despatched from Holland direct to RES (their authorised agent in Guernsey) and authorised them to effect the repair. How brilliant was that!

Yesterday, Robin of RES appeared on Play d’eau and checked the fault remained. It did. Climbing the radar arch and pony mast, Robin unscrewed the cover from the aerial array, removed and replaced the faulty aerial and appeared back in the Pilot House to check it was now working. It was. Brilliant, again.

One mother-in-law cockroach exterminated.

Any more bugs?

Yes. Two hours later, three more bugs dared to surface. The original ‘Heading Data Missing’ on the nn3d, and two relatively new ones showing as ‘Log’ and ‘EPFS’ in the Radar alarm log. Yet all with no indication of equipment failure.

To me, I don’t believe there’s anything more wrong with any of the equipment. Deduction tells me these bugs are more like mosquitoes hiding in the sentences being dropped onto the nn3d backbone or the speed at which they are talking. A mismatch or confusion somewhere. Time will tell.

So, having exterminated a cockroach we now have three mosquitoes.

Now where’s that DDT?

Simrad v Furuno – the problem solved?

Andy Craig of MEI resolves the Simrad AP 70 autopilot problem

In my post ‘The Finishing Touches’ I hinted at a major problem between the Simrad AP70 autopilot, the Furuno satellite compass and NavNet3d electronics, and that I’d report on it once it had been resolved.

As the customer, I was faced with having to leave for our summer cruise to the west coast of Brittany with no autopilot. Not a good idea, especially having spent the winter refurbishing Play d’eau which had been featured by MBY in their April 2013 issue.

Who were the stars in understanding customer service and resolving this customer issue? Andy Craig and Jim Staig of MEI Ltd whose website is Electronics on Board.

The problem

Whilst in Auto, the Simrad AP70 autopilot would go into alarm every few hours stating the steering compass information had been lost.

This would sometimes be amplified in nuisance by the Simrad AP70 refusing to go into Auto or Nav at all, for the same alarm reason.

The Customer Service

Bear in mind that all the Furuno kit is tried and tested whilst the Simrad AP70 is the new boy on the block with Play d’eau having the second.

Also bear in mind that Customer Support at Simrad relies on one person alone, who has to cover every product made by Simrad, Lowrance B&G and Navico.

So what should be said about Simrad’s response? Let’s just say that the Simrad AP 70 was a new product and had not had the benefit of months of sea testing in anger, and their Customer Service desk (one person) is heavily overworked.

What did MEI Ltd do?

MEI was brilliant. They said the words any customer would want to hear. ‘Leave it to us, Piers, and we’ll sort it – we will.’

So last week, I collected Andy Craig from St Peter Port’s Condor ferry terminal and we drove to Play d’eau.

Before tasting his coffee he was already laying out his plan of attack. ‘First, we’ll blueprint what equipment is outputting what sentences in case of data collision. Then we’ll install a new cable from the satellite compass direct to the Simrad AP 70 autopilot to by-pass the Furuno NavNet3d, and finally,’ he added with a wry smile, ‘I have a software update from Simrad to install, yet no one at Simrad seems to know what the changes to the software are….’

Has it worked?

It appears to have been successful. Why do I use the word ‘appears’? Because I’m naturally cautious, nothing else.

So full marks have to go to MEI Ltd who kept on the issue and made sure they resolved it.

MEI Ltd

MEI Ltd are authorised Dealers for Furuno, Simrad (Navico), Raymarine, Garmin, Intellian, ICOM, KVH, Actisense, and the list goes on.

MEI regularly installs on leisure and commercial vessels in the UK, the south of France, Majorca, Minorca, Antigua and Corfu.

The finishing touches

Martin at Beaucette Marina

Despite the extensive research Lin and I did when specifying the electrics and electronics refit for Play d’eau, operational niggles came to light as soon as we started cruising and living on board.

Apart from one major problem involving the compatibility of the Simrad AP70 autopilot and the Furuno electronics (which will be the subject of a separate posting once it’s been resolved), most niggles were small and trivial in comparison. For example, the default settings for which video camera should be displayed on which screen when cruising; a link from the TV to the saloon’s main sound system; the installation of a Wi-Fi unit to connect to our shore telephone line which carried ADSL as well; establishing why the Navtex had stopped receiving messages, and so on.

So, last Friday, Martin, Play d’eau’s ‘resident’ electronics installer, arrived on one of Guernsey’s Blue Island ‘planes. ‘It was a tiny aircraft and there were only six passengers,’ said Martin. ‘It took 25 minutes, and I loved every one of them!’

Driving straight to Play d’eau Martin began attacking the list. Good progress was made until we needed some RG59U video cable. The only hope was the Guernsey marine electronics company RES but it had closed for the day. However, we sent an email from their website and within moments we had a telephone call. ‘Yes, we have some in stock,’ said Robin. ‘Come by the shop in the morning – we open at 0830.’

By the time Martin had to catch his return flight the next day, all niggles had been resolved apart from the Navtex which needed a new aerial.

Did Martin like his time in Guernsey? ‘It’s an awesome and beautiful place,’ was Martin’s comment. Says it all, doesn’t it?
