Diorama Shipwreck tanker Olympic Bravery, 1976, France 1:700

At sea, the tradition is the same as in the air, no matter what happen's it's the captain's fault. It is from this responsibility that a Captain's authority issues. Many examples exist, even if it's not your fault, external circumstances or just bad luck, It's your fault.

[Iceman 29]

That�s right, Tom.

I started the design of the aft mast. This mast has been reinforced probably after the sea trials with legs on the front.

You can see on this picture that they are not present in the Saint Nazaire ��Forme C��.














I didn't make too much progress today, I was busy scanning a small part of the huge 1/200 scale plan of the ship in the shipyards that my friend Roland kindly lent me. It takes time and space... I still have a lot to scan.

[Fliger747]

At 1:200 it would be large model! Are you scanning in sections and combining with photoshop or some such? Fortunately not so big a document reduced to 1:700.

[Iceman 29]

Yes Tom, it's combination of several scans of my IRIS (canon) scanner. I use Gimp (free) for the combination. The final picture is near 236 mo..



The ship is time consuming with its scuttles, doors etc. A good training for the T2 tanker which has two of them and which I have to draw and print to finish it.











Today changes to the staircase layout at the rear of the castle, this was not the correct final configuration of the ship. Modifications were made in Brest, probably following the sea trials. 5 reinforcements were added between the ship and the chimney block...

The stairs were moved to the sides. The modification work on the mast was also done in Brest probably. The reason for this was always the excessive vibration of the ship.

The ship was originally built in Saint Nazaire.



Here you can see the modifications.









On the right is the original configuration, on the left are the modifications to the stairs to be able to place the reinforcements.



The final version.



I found a lifeboat plan that looks like the ones in the O-B on the net.





I'm drawing this boat at 1/200, but I'll be able to reduce it to 1/700 easily. At 1/200 it will be useful for other future ships of the same period.

I used another method to make the 3D shapes of the lifeboats. In the vertical direction, it is rather conclusive and fast, to see with more complex hulls, nothing is ever won with Fusion 360.

[Fliger747]

Pascal:

Interesting work and problem solving as always! Are you going to print the inclined ladders integrally with the superstructure? It will be interesting to see how they come out, I did get them to print quite well in 1:196, but a rather different scale! The working the horizontal layers looks like it might work for small craft oil the primitive program I am using, with frames, it fails to be able to blend at the very bow and stern for a double ended boat.

Yes combined files can get very large! I had some panorama images hit 750 MB! Reduced to 1:700 your ships drawing shouldn't be to bad, especially in monochrome. I have some ARL drawings for a future project that I need to reduce to 1:120 from 1:96. I could go your route or just drag it down to FEDUP and have them crank them out.

[Iceman 29]

No, Tom, it's impossible to print these stairs at 1/700, as well as railing. I will use PE. I just drew them for fun.

The railing is 0.1 mm diameter for the top bar and 0.07 mm for the bottom ones. It can't be printed.

For the 3D drawings of the hulls, it's always the 2 ends that are the problem.

I'll stop here for the moment with the lifeboat which will only be 10 mm at 1/700. I will see later to continue it, at 1/200, and maybe at 1/30 with many details.

The typical 1970's shape is quite nice. Often equipped with Lyster engines that were started with a crank, we often got good feedback in the arm or wrist .

Nowadays the boats are covered, waterproof and are equipped with an electric starter, fortunately.









In situation, length 10 mm, it remains the davits to draw.

[Iceman 29]

I have some pictures of the davits.













Here are pictures of her sister ship Alexander E Onassis, which was also called Lyria under the flag Port aux Fran�ais, sailing for Shell France.





The Lyria: no luck for this series which will be hit by the French nuclear attack submarine Rubis off Toulon in France.

Collision off the coast of Toulon The accident caused by a submarine resulted in a slight pollution
The nuclear attack submarine Rubis collided with the giant oil tanker Lyria while surfacing at 10:35 pm on Tuesday night, August 17 to Wednesday, August 18. The damage was slight, but the 343-meter long tanker lost 2,800 tons of its cargo of hydrocarbons, causing pollution off the coast of Fos-sur-Mer. By Thursday morning, the oil slick was only 800 metres wide and 200 metres long.

TOULON from our correspondent The story of this collision between a submarine and an oil tanker: at the beginning of the night, the sea is calm. The horizon is clear and the Lyria is holding its course.



Under its hull, the Rubis begins its "sighting" phase after a training exercise. There is nothing unusual about this flagship of the French Navy, measuring 74 meters long and 8 meters wide, and weighing 2,400 tons. It was the first attack submarine to be based in Toulon, in 1983, and a few years ago it achieved a first by reaching its home port in Noumea without resurfacing. However, at one point, the seventy members of the crew were shaken by a rather violent shock. The submersible had just hit the tanker, which continued on its way unperturbed. There is no damage on board the submarine, except at the level of the "nose", this dome in composite material placed at the front and protecting some sensitive electronic equipment. Without delay, the Rubis set course for Toulon. It returned to the base of the Mediterranean submarine squadron, where the fourteen torpedoes and missiles on board were unloaded on Wednesday morning. At the same time, the tanker Lyria arrived in Fos at 7:15 a.m. the same day, without anyone on board being aware of any problem. It was only in the middle of the day that the semaphore of La Couronne, located near Martigues, reported the presence of a slick in the Gulf of Fos.

A 5-metre long breach An alert helicopter and then two planes from the French Navy flew over the scene in the afternoon and sprayed dispersant treatment products. The tanker was then docked and further investigations revealed that 2,000 tonnes of oil had escaped from the tanker's bunkers. The tanker had a breach 5 metres long and 50 centimetres high at the level of the starboard forward hold. Anti-pollution booms were set up off the coast of Port-de-Bouc, threatened by a slick 1,500 metres wide and 2,000 metres long, pushed towards the coast by a light breeze. After this accident, two questions arose: how could such a technically advanced submersible collide with such an imposing vessel and why was the tanker's captain not warned of the collision by the maritime authorities? To the first question, the Pr�fecture Maritime gives a technical answer: "The 'regaining of sight' phase consists of a submarine passing from a situation of total and deep immersion to a periscope immersion. During this period, the submarine is almost deaf and blind, its external perception being limited to sonar. "As for a contact, which should have taken place, with the tanker, the public relations officer of the Pr�fecture Maritime is cautious: "It seems that the submarine called the tanker by radio, but without success. ......

A Destroyer Escort that I used t drill on plus a sub that I had been aboard for underwater sound range runs, later collided with each other off Hawaii. Both noticed...

[Iceman 29]

The "3D navigation" is more complicated!

Little progress on the pivot davits, not much time to do more, other hobbies take up my time too... �

A simplified davit for this scale will suffice, I think.. I'm having a print test done. It's small.









Trying to print a lifeboat / davit. It's very small but very accurate, I could go into more detail actually, but you'd need a good magnifying glass to appreciate the micro details.

[JIM BAUMANN]

what most excellent design and rendering works-- very impressive.

You also have some good photos of the real ship--which explain so much that plans alone cannot/...dont

GREAT project!

JIM B

[Iceman 29]

Thank Jim!

I also had thanks to my friend Roland who provides me with plans and HD photos and interesting information a few days ago by the technical director of the shipyards in Brest (AFO) in post at the time, on the finishing work and tests carried out in Brest before the sinking.

It is fascinating and very instructive.

[Iceman 29]

Test printing of the castle which is not yet finished in order to see the problems linked to 3D printing.

But it came out pretty well. Some defects in the facade will be rectified.
The outer walkway rail will be refined in thickness, it's possible.

And continuation of the design of the castle with its reinforcements, the transversal bridge and the drum machine with this beautiful shaped chimney.

The 1/700 PE from Trumpeter is very suitable. Ic I have glued a scale for testing.













Second test. Same defect on the fronton.

I'm going to try a third slanted print, it's the floor of the bridge that's messing up.

The mast is top, printed except of course because of the painting of the bridge roof.

The rear section is being printed, it will take 12 hours. 225 mm high.

[Iceman 29]

Well, I got to version 4 of the castle, I tried it tilted, it worked well, but I have the layers that make me corrugated and it's hard to sand down.

So I removed the bridge board and reduced its thickness at the level of the fins. I printed it straight.

It's not perfect but it's acceptable.

The rear section printed well, it's rough on the pictures, I had fun mounting the castle. The second copy is being printed.

[Dan K]

Truly beautiful work.

[Iceman 29]

Thank Dan!

Assembling the rear today. Sanding. Priming. Sanding.

"Nice" masking of the two castles, it was long and tricky. Thanks to the good scalpel with a new blade!

[Iceman 29]

Some progress on the castles mainly, double work. Painting and laying the delicate 1/700 PE.

[Fliger747]

The superstructure with the PE came out very nice indeed. I read a few posts above about the lifeboat with a Lister Diesel motor. I had one of those to power the electricity at my house for a few years when I first built it (out in the Alaska wilds) with a crank and compression release. Fairly easy on land, perhaps a bit more exciting in a small craft!

We are of course anticipating more work on your very interesting "other" tanker.

Regards: Tom

[Iceman 29]

Good engine Tom, you must have some experience tu run it..

On small lifeboats, I had this kind of mono cylinder. After here it's easy, but in a small, crowded ship it's another matter.




It's quite simple to build, you can concentrate on painting and pausing the PE and take your time, this is my first 1:700 ship.

I painted the deck in green. I wonder if I should use a satin varnish to homogenize it. To answer this question, I'm going to do a test on the test bow.

This version will not be aged, the ship has just been received by the owner from Brest.

The second "wreck" version will be of course. I'm going to enjoy it!

Some pictures of the work done this afternoon, the 2 "castles" (French expression) are almost finished, I'll go back to the design to finish the drum machine with the chimney. I still have a few deck accessories to design, like the siphon and washing tower for the inert gas system, more winches, the pipes on the deck for the crude oil tank washing guns, the manifold, the loading masts etc..

[Fliger747]

In the early age of fighting sail, ships had "castles" which were such redoubts for close quarters fighting. Many ships today retain an elevated deck at the bow, or the "Fore-Castle" , pronounced "Folk' sul" more or less. Model photography is often difficult and to look as good as they do, they have to be really good as the camera loudly amplifies any defects or issues. Photography of women probably led to the development of "Photoshop". You could fall into great disfavor with a lady if she didn't like the result!

Everyone has their preferences for satin coating, with issues such as convenience and availability intruding. I do have some dull coat, a good product but one that requites the airbrush, thinners etc. Here, Krylon product in a large rattle can (Krylon 1311) produces a good result with a light indirect misting.

The "wreck" will be particularly interesting! I remember (maybe) some project which was Yamato on the sea floor as a diorama.

[JIM BAUMANN]

very very impressive and fast work!

even in 1/700 its a biiig ship!

Maxi,is Tres Bien !
