Hello Michael,
Nice tug, indeed and also with flanking rudder! Thanks for the pdf... .
Also, I like the design of the Kotug with 3 Schottel azimuthing propellers, of whom I dont attach a picture, to avoid angering sam simmer who doesnt like the magic beauty of the Kotug.
But I found an short presentation of the development; from this, I can infer that a mathematical model giving realistic results is not straightforward, to say the least.

And they give a bollard pull of 75t with only 6400hp.

Luc

Hello Luc,

It is now officially summer, but it look more like fall -- brisk NW winds and possibility of showers

You are quite right about the rotor tugs -- beautiful and versatile beasts. Take a look also at:
http://www.seabulktowing.com/sdmtech.html (http://www.seabulktowing.com/sdmtech.html)

Many towing specifications in the US (Navy, LPG, etc) now call for tractor tugs of some type, whether Schottel or Voith-Schneider cycloidal, and these do give impressive mobility and bollard-pull. The story is that they are hard to handle, though -- at least for tug captains used to conventional screw propellers. More than 1 company has set up its own simulator to train its people.

Cheers,
Michael

Wow - Such great photos

Is that yellow tug built to some standardised design?

It seems a familiar design. Looks just like those under construction in SantCruzzi (Bilbao), Spain.

It also happens to be in SS08!

Here are the 'funny' tugs doing some heavy work:

This is on the channel between the Wester and the Oosterschelde.
They are transporting a new containercrane for the MSC terminal in the Delwaide dok, in the port of Antwerp.

Captain Davies · « **Reply #31 on:** June 24, 2007, 12:07:46 »

That's impressive! I wonder how they got it on the bardge?

Sam · « **Reply #32 on:** June 24, 2007, 15:58:20 »

I was lucky to see this, We were driving home from a weekend sailing and when we just wanted to drive in the tunnel to drive trough under the channel I saw something strange going trough the bridge over the channel.

My dad parked the car near the channel nd toulk some pictures.
The right place at the right time.

Here are some more pictures.

How it looks in the car when your driving on the highway.

I'm sorry for the bad quality of the pictures.

I think they lift it up and ride it on the barge with this (http://www.mammoet.com/plaatjes/db/images/big/237.jpg).

Captain Davies · « **Reply #34 on:** June 25, 2007, 15:35:02 »

Yeah, that makes sense, though it would probably have to have a bigger bed; the one they used.

If the cranes run on rails (which most do), I would expect that they have welded rail sections to the barge and run them on. I remember seeing something on one of the discovery channels or national geographic when several container crains were made in the far east, rolled onto a vessel and shipped to the US accross the Pacific!

They must have had a tight schedule with the tide, or is the tide at Rotterdam constant?

One can tell the question is from a Brit -- Rotterdam (more-or-less at the center of an oscillatory system) has very little tide.

Yes, that is possible with the Dockwise ships and a chinese company where I can't spell the name of.
But this crane is only the upper part, it can't run on rails yet.

The transport you mean is with ships like this (http://www.zpmc.com/ship_detail.asp?Article_ID=108&Column_ID=36).

True, I should open my eyes a little.

What sort of ships are the Seven Oceans and Polar Queen? What are they used for?

Sam · « **Reply #44 on:** July 03, 2007, 18:06:23 »

I think they are used to lay cables on the seabottom.

U can see a large drum on the ship.

Yeah I'd wondered about that, I guess cable laying makes sense. But what's the helipad for? And no "for helicopters to land on" sarcy comments please, I mean why does a helicopter need to land there?

mporter · « **Reply #46 on:** July 03, 2007, 21:04:05 »

They are pipe-lay boats. I think the Seven Oceans used to be called something else when I saw her in New Orleans.

Many jobs for bigger pipe-laying vessels with the explosion of offshore oil drilling.

About all deepwater oil-field vessels have helipads since that is the main way people get around.

Cheers,
Michael

Sam · « **Reply #47 on:** July 03, 2007, 21:21:52 »

I don't think she could be called else beceaus she allways had the name Seven Oceans.

Take a look at this:http://www.tugspotters.com/verslag/seven%20ocean/reisverslag.htm (http://www.tugspotters.com/verslag/seven%20ocean/reisverslag.htm)

Must have been a different vessel then -- similar pipe wheel, though.
