Model ships
« on: October 10, 2009, 05:37:43 PM »
I have been told by a member of this forum some of you might be interested in a model ship I built.

Its a semi submersible ship, ie, it sinks the main deck below the waterline in order to load a cargo - a ship or oil rig, then re floats and lifts the cargo clear of the water.

There are no plans available to modellers for this ship. I started out with a set of hull lines on an A4 sheet of paper and a load of pics off the interweb.

This model, at 1:200 scale, is 1.4m long, 300mm wide and weighs about 15kg dry.

I used 4 reversible gear pumps, 4 pumped ballast compartments and 4 free flood ballast compartments.

This boat requires 7 channels to operate, 1 for each pump, one for main drive, 1 for rudder and 1 for the bowthruster.

Anyway, here it is. And just in case anyone starts wondering, its not for sale as I have just sold it to fund a milling machine from one of the members here.
If it works, take it apart and find out why!

Br,

Thanks for that, yes these ships are quite amazing. The stability of them when they submerge becomes a nightmare, its a really risky operation that doesnt take much to get wrong.

Very nice indeed. 

I have seen TV shows on these types of ships but I had never considered what would be needed to make a working scale model.

Thanks so much for sharing.

The challenge is being able to state any problem in such a manner so as to allow a solution.
