Life at the end of the road

The list!

Well, that’s it then, the holiday has started, a whole month to work through ‘the list’, not that I’ve actually written one out yet, but I’d better. Not that I’ve actually ever finished one of my holiday lists but I do try.

The last shift was one of stark contrast, starting as it did with storms, rain and several missed sailings. However the last few days were a pure joy, no doubt helped by the thought of four weeks off work, arriving home in daylight on Sunday and the best sunshine of the year so far.

Light both ways

It’s always a bit of a ‘milestone’ for the year when I can get to work and back in daylight, and this Sunday was the first. OK, it’s a late start and early finish, but even so, my next shift will be in BST so I may even do it during the week when I return to work at the end of March. That will be a real ‘milestone’, an early Easter for my first shift, I love Easter. Not so much now, but in a previous incarnation I spent the whole winter looking forward to Easter and a trip to the West Coast to do some wreck diving. Now I’m a wreck myself and have not dived in a couple of years but my love of the West Coast has never waned.

The daylight trip to work on Sunday had me taking a minor detour at Holoman to admire this dirty great big generator that was busy powering the settlements north of Oscaig. Work in the forest felling the infected larch and rhododendron necessitating a section of the line to turned off. Dunno what size the genny is but it certainly was quiet.

The day aboard Hallaig consisting of just a couple of trips to Sconser and back, a BIG BREAKFAST a few drills and the usual PM, (planned maintenance). The main PM job this month being a testing of various emergency functions a blackout and then recovery.

Safely tied to the pier on ‘shore power’.

 

005

Normal sailing mode, 1 DG and the drives engaged.

 

006

Something serious has happened so the ‘Start All DG’s’ button is pressed and all three Volvo generators come on line. Once they’re all ‘on the board’ we go around ‘emergency stopping’ them one by one.

007 

Of course once you’ve pressed the last one the ship blacks out, which is then a good time to test the watertight door. 008

This must be able to close twice and open once under its reserve power supply. Meanwhile the Emergency generator on deck 4 must automatically start up and power up the Emergency Switchboard within a certain time.

 

009

That’s it on the right of the screen with just about everything else in a fault condition.The EDG is however doing everything it should by feeding the ESB (emergency switchboard) thus ensuring all the ships essential fire fighting, pumping, lighting and life saving equipment are maintained. Once all that is checked the emergency stops are reset and the ship automatically restarts the main generators and closes all the breakers. However a further part of this drill is to do it manually and also start and run up each drive unit remotely, it’s great fun Smile

More essential maintenance, this time on Monday when it was time to take oil samples from all the generators. These are taken with a special little vacuum pump, the oil being drawn via a sterile tube and deposited in sterile bottle for posting onto a specialist company down south. This is an invaluable early indicator of any problems that may develop into something serious.

Signs of spring

Well, the first one was seeds germinating in the Land Rover Smile seriously though, aside from the ‘mixed grain’ for the hens taking root under the rear seats of the ‘Old Girl’ there was frog spawn.

There were also birch tree buds on this ‘witches broom’ https://en.wikipedia.org/wiki/Witch’s_broom I found at Torran, along with fresh shoots on some honeysuckle.

Listering

The main task today was doing a bit of work on a couple of Lister generators, first for my neighbours at ‘Number 3’  https://www.airbnb.co.uk/rooms/8188794?s=bfTthU6x

013 027 028

Cyril the Lister SR2 was getting a new ‘start module’ a Murphy ASM 170 like the one I have on my HR2 at Sonas. Unfortunately it came without the wiring loom, that’s a mere £36 extra plus £12 postage and won’t be here for a week!!! http://www.fwmurphy.com/products/controls/asm170 . It’s a great piece of kit and has all the functions you’re likely to need to start just about anything, however supplying it without a wiring loom is a bit pants. It also needs a 110v supply to tell it the generator is running!!! fine in the USA but here you need some kind of transformer. When I did mine I used a shaver socket, for this one I bought something like this http://www.ebay.co.uk/itm/50W-Power-Converter-Adapter-AC-220V-240V-to-110V-120V-Transformer-US-Plug-/291322907540?hash=item43d432cb94:g:ilkAAOSwfcVT~woD .

Having gone as far as I could with that I set off for the Schoolhouse at Torran.

 

017 016

Here the trusty Lister ST2 was needing a starter solenoid as it had gone ‘open circuit’. Whilst there the Rolls series 500 batteries got a drink of de-ionized water.

 

018

This is the 24V 800Ah bank that powers the house, it’s half the size of mine but perfectly adequate for this ‘off grid’ property.

021 022 023

After sorting out everything at the Schoolhouse Molly and I went for a wander in the afternoon sun along by the Old Mission house with its amazing stone work and onto Torran proper. Everyone, including myself calls the Schoolhouse ‘Torran School’ but it’s not actually in Torran, the boundary is actually the burn at the Mission House 30m away.

That done, it was away home with the solenoid,

030 031

I took it back to my workshop and drilled out the rivets in the hope that it was just a loose connection but as soon as I prised the thing apart I was greeted by the unmistakable smell of burnt out electrics Sad smile

032 033

That was it really, well apart from the hens, pigs and making dinner.

  1. I don’t see the batteries on that screenshot? surely they are connected in to the whole system and can take over if the gennies go down so why would it all go black?
    and the hydraulic door is that not still powered or is it on an accumulator?
    I just find it odd that you have all those batteries and yet have to rely on an emergency genny?
    Magic smoke has escaped from solenoid.

    • Hi Kev,

      the drill is to simulate loss of power including loss of batteries. You are correct, the batteries would normally be online and ‘pick up the slack’. The EDG is a Lloyds MCA requirement and even if the ship had six other generators and four battery banks it would still have to start within a specified time and energize the Emergency Switchboard in the event of a ‘blackout’ even if one was virtually impossible. The hydraulic door has it’s own batteries which must be capable of opening and shutting the door under ‘stored power’ but it also had two little hand cranked generators that can be used if the batteries go flat. One can be operated in either engine room and the other from deck four. The main ship LiFePO4 batteries do not appear on that mimic as they feed the ‘DC link’ between inverter and active front end.

  2. It must be tempting to apply the special vacuum pump and send in an oil sample from The Old Girl by “mistake” to see what might go wonky next.

    • Very tempting indeed Dr G 🙂
