Agreed. 

 

And I particularly liked the axe, handsaw and bolt cutters hanging up in the workshop. Just what one needs for adjusting the tappits on that engine!!

It was interesting to learn that the engine is 25 years old with 125k hours on the clock. It does, however, get a complete overhaul every 5 years, 25k hours.

Fascinating pictures. Thanks rgreg.

I was particularly pleased to see that last shot of the upper deck where it showed that red container on the top had finally been landed.  I was beginning to think they were just taking it around Europe for people to look at!

This evening we have docked at Vasteras, our northern most destination. Here we will spend the night and they will work the ship tomorrow, when I will be allowed to set foot on land for a few hours and have a wander around town. Today's journey has been stunning; weaving our way through the huge Lake Malaren which is dotted with many tree-clad islands. It is a most unlikely setting for a container ship! Our exit from Sodertalje involved some adept steering from the skipper, who handed over control to a pilot for the voyage across the lake. All in all, a truly amazing day.

Ha! and we've gained an extra layer

Some of that looked a bit of a tight fit.

Looks a fascinating trip.

 

I find it fascinating they employ a pilot to steer the ship through that tiny gap.

 

You'd think someone who flies for British Airways would be just as likely to crash the ship as the regular captain, wouldn't you?!

Well, so far I have spent the princely sum of £1.34 and that was only because the crew had gone to the trouble of giving me a catalogue of goods to be delivered to the ship at Kiel, so I bought some bottled water! I'll avoid the Swedish shops tomorrow like the plague and stick to the interesting stuff.

For anyone who's interested, here are some photos of the complete unloading of the ship this morning (4 hours). It is interesting to note that there are 2 more layers of containers below the visible deck, only exposed when the metal covers are opened.

Proper ships, a whole world that I know nothing about. Must be quite 'handy' though as some of those bridges and bends are a bit tight and as we all know a bit of wind can be a right pain in tight corners. Wonder how it gets reverse? great big gearbox? Thanks for posting the pics, fascinating stuff.

Your first sentence is an Interesting comment on an almost secret world! At one time we, as a nation, we were proud to call ourselves a maritime nation, and nearly everyone in the UK considered that they had the sea in their blood! Although our own national involvement has declined significantly, thankfully the industry continues and this very interesting marine activity continues day and night with most people not being aware of it. The ship featured is known as a feeder container vessel, which trades around our near continental waters. There also is another, bigger layer of container shipping traffic, doing similar trade but world wide. It's a fascinating world which I have been involved in for most of my life. Welcome to my world.

Yes, it's been fascinating to get so close to the whole operation with virtually no restrictions. I think being the only passenger on board has made it an even more unique experience. As for steering, these guys are very skilled at it, which is just as well given some of the constrictions that are encountered! What is interesting is that manual steering is only used in those kind of circumstances or docking; the vast majority of time the ship is on auto-pilot guided by GPS.

We're just departing from Vasteras to Oxelosund for our final pick-up then homeward bound. So a new, if temporary, view from the bridge!

No gear box on the really big marine engines.  The crankshaft is directly coupled to the prop shaft with a thrust block just aft of the engine.  I though that I saw it on one of the engine room photos.

 

To reverse you stop the engine.  Change the valve gear and start it again in reverse.  There is no starter motor.  Compressed air is fed into the cylinders to start the engine turning.  A  motor ship, unlike a steam turbine ship is as powerful astern as ahead.  Steem turbine ships had a dedicated reversing turbine which is always much smaller than the ahead turbines.

But the efficiency of the propellers will not be the same in reverse as ahead?

Correct.  Just like a narrow boat.

Never been on one but spent many years nearly being run down by them as we crossed the channel, biscay(tricky), straights of Gibraltar and the Messina staights. Thank god for AIS so we could plot their course and speed- how on earth do you cross the path of one of these when you are doing 5 knots and they are doing 25knts .......and can't see you. Just the view from the brigade from rgregs  pickies are frightening.

These days many  ships, large and small, are fitted with CP (controllable pitch) propellers whichmeans that the engine is not stopped. Instead, astern propulsion is selected by changing the pitch. This has also been used on steam turbine vessels, as well as motor vessels, for many years. 

 

It is possible  that Odin is fitted with CP gear; maybe RReg can confirm.

Looking at the wheelhouse engine control photos and also the engine room local controls she appears to be fitted with a KaMeWa CP Propeller.

Without contradicting you I would add that none of the cargo ships that I sailed in had controllable pitch props. Most had four blades some had five.
