Just wondering Pascal, where have you got all your dimension information from? Your drawings are highly detailed and would require a lot of actual drawings to prepare.  Do you have full construction drawings of the vessel or are you filling in details by eye?

[Iceman 29]

Steve, I have an original arrangement drawing from the yard of Saint Nazaire to 1/200 scale.. Very large plan.  And lot of pictures from my friend Roland who is a naval specialist.

 

I'm making good progress on the castle.

Note the pipe and the No Smoking sign emblazoned on the accommodation block front!

He is the master of the ship. 

 

The ship is not loaded and has never been loaded except with water for its ballast (no double hull at the time), so no worries on that side, the ship is "Gas free" but that's a good point Dave!

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.

 

 

[longshanks]

Could this be your next project Pascal??

Wouldn't be the first, or last time that's been done - some of ours had to be reinforced and fittings replaced after sea trial vibrations saw bits of signal light, radar etc raining down on the monkey island - hard hats on the bridge!

[Iceman 29]

Yes, Dave, this is quite common.

I'll put up pictures later of the last ship I sailed on that underwent the same transformations after the O-B sea trials.

 

My plan is a 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.

 

First version 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.

 

 

 

 

 

 

 

 

 

 

 

[Courageous]

Making great progress since my last visit Pascal, great work as always. How the heck did you manage to scan that drawing?!

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 :roll: .

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. 

 

 

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 Français, 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 Préfecture 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 Préfecture Maritime is cautious: "It seems that the submarine called the tanker by radio, but without success. ......

I'm dumbfounded by this.

Not to mention skinned knuckles! The crank handle always had enough clearance to turn, but there was usually a thwart, duckboard, casing or similar close enough to reduce that clearance to zero when enthusiastic cranking.

Lister's or Petter's were fitted to most of our open boats. Basic but reliable even when neglected and abused.

[Iceman 29]

Experience, Dave! 😂

I've plenty of that, and the scars to prove it!

[Iceman 29]

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.

Yep, seen a few of those. He's not been taught how to hold a crank properly though! Thumbs same side as fingers!

[Iceman 29]

When you have no thumb, it's much more practical! ➡️

[Iceman 29]

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.

 

 

 

 

[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.
