Original Builder Plans for
Titanic, Olympic and Britannic
On this page I show you some of the original
plans of Titanic und Olympic as well as of the third sister the Britannic, that
were used to create the Hahn Titanic CAD plans. But you should know that most
of the plans show the Olympic as planned and many changes and additions that
made Titanic unique never find their way back into the plans. Therefore the
original plans were necessary as a base for creating the CAD plans and a
continuous verifying of the plans against pictures and wrack footage was
unavoidable, to show Titanic in my plans as she sailed on her final voyage.
Anyway the plans are very interesting because
of many handwritten comments and additions like the screen on A-deck or the
change of the wheel house on the bridge.
The plans are first shown in total supplemented
with two detail views. Most of the plans are in the scale 1:48. This affects
mainly the deck plans, the shell plating plan and the lines plan. These have in real a length of 6 to 7 meter.
1.
„Rigging
Plan“ of Titanic
Der Rigging Plan zeigt im Wesentlichen die Takelung der
Titanic. Er ist im Maßstab 1:144 gehalten.

„Rigging
Plan“ of Olympic after sinking of Titanic
Very interesting plan of Olympic
after the sinking with the whole boat deck full of lifeboats. Plan is drawn in 1:144.

3.
„Boat
Deck” of Olympic/Titanic
The plan in 1:48 shows the boat deck of both
liners with the outline of the deck houses. Interesting is the change handwritten
of the wheel house, which was not adopted the way for Titanic as drawn. The
wheel house of the Olympic was curved and now direct view from nock to nock was
possible. On Titanic the front was changed to straight.

4.
„Promenade
Deckhouse” of Olympic/Titanic
This plan in 1:48 shows pretty nice the
arrangement of the windows on A-deck. It has also many neat comments and
changes for Titanic like the handwritten change to the screen outside A-deck
which was decided very short before her departure from Belfast to Southampton.

1.
“Promenade
Deck plating” of Olympic/Titanic
Here A-deck is shown in 1:48 with all plating and
cut-outs fort he boiler. Interesting are the details for the expansion joint.
|
|
|
|
|
|
2.
„Bridge
Deck” of Olympic/Titanic
This plan shows B-deck plating in 1:48.
|
|
|
|
|
|
3.
„Shelter
Deck” of Olympic/Titanic
The shelter deck or C-deck was the first to run
the whole length of the ship. This plan is also in 1:48 and very long.
|
|
|
|
|
|
4.
„Upper
Deck” of Olympic/Titanic
|
|
|
|
|
|
5.
„Lower
Deck” of Olympic/Titanic
At the Lower deck you see many big cut outs
fort he boilers and the machinery. It is drawn in 1:48 and shows the deck only
a bit over the middle line of the ship.
|
|
|
|
|
|
6.
„Poop
Deck” of Olympic/Titanic
The Poop deck was the part of the ship where
most of the remaining passengers crowded, before the ship went down. The plan
is drawn in 1:48 and shows the openings for the steering machine as well as the
position of the docking bridge and the cranes.
|
|
|
|
|
|
7.
„Docking
Bridge” of Olympic/Titanic
The docking bridge which stood on the Poop deck
is drawn in 1:48.
|
|
|
|
|
|
8.
„Lines
Plan“ of Olympic/Titanic
The lines plan is one of the most important plans
and shows in 1:48 the shape of the hull as well as the frame set of both
liners. The style is a bit confusing as it shows the fore and rear part of the
ship moved in one of the other.
|
|
|
|
|
|
9.
„Shell
Plating Plan“ of Olympic/Titanic
This plan in 1:48 is also one of the most
important as it shows the arrangement of the plating with all the rivet lines
and doubler plates and the portholes for both sides. But one must know that the
plan is only 95 % correct with Titanic and had to be checked back with
photographs of Titanic during fitting out. The style of the plan is interesting
because it shows the complete shell including the bottom plating. This is the
reason why the bilge keel is shown much to high.

10.
„After Section“
of Britannic
The rear frames in detail with the wings is
shown in this plan in 1:48. It was very useful for Titanic and Olympic because
the double hull of Britannic, which was constructed after the sinking of
Titanic, was only between the well decks.
|
|
|
|
|
|
11.
„Midship Section“ of Olympic/Titanic
This plan shows the main frame or midship frame in 1:48 with all decks and pillars.
|
|
|
|
|
|
12.
„Hydraulic Riveting“ of Olympic
The upper part of the hull was riveted
hydraulically. These rivets were the only ones which were clearly visible
because they had a round head. This plan shows the riveting only of a small
part of the shell but the pattern is visible which can be adapted to the rest
of the hull.
|
|
|
|
|
|
13.
„Steering
Machine“ of Olympic/Titanic
The steering machine worked with two little
steam engines of which one was only a back up.
|
|
|
|
|
|
14.
„Machinery
Compartment Cross Section “ of Olympic/Titanic
The following three plans of Titanic’s
machinery look quite similar as the ones which were published 1911 in the
shipbuilder magazine, though they have much more detail.
|
|

Compartment Longitudinal Section “ of Olympic/Titanic

„Machinery
Compartment GA Top View “ of Olympic/Titanic
|
|
|
|
|
|
17.
„Framing
Plan“ of Olympic/Titanic
The framing plan shows the length of the single
frames. For the CAD plan this wasn’t necessary but from an engineering
point of view it is an interesting plan, drawn in 1:48 with many neat details.
|
|
|
|
|
|
18.
„Stern
Repair“ of Olympic
In 1922, Olympic needed a repair of the stern
stem because of a crack. This plan shows pretty nice the shape of the stem and
the lines of rivets.

19.
„Rigging
and General Arrangement Plan“ of Britannic 1/3
Even if not useable fort he Titanic CAD plans, the
plans of Britannic are very interesting because they show her as a hospital
ship with the huge gantry davits.
