TI8


Titanic 9 – Plan Ordering Code TI9 – Price Per Sheet $35.00 USD
This plan sheet is a drawing of the shell plate expansion.  This drawing has never been found among the Titanic drawings.  It was created using the Olympic framing plan and the Olympic shell plating plan.  The plan is of constant scale both vertically and horizontally.  All hull plates on the starboard side can be visualized in this expansion.  This plan will help the modeler in plating the hull.

Special Note: It should be noted that the shape of individual plates cannot be derived directly from the shell plating expansion.  The shell plating expansion shows the shape of plates in the x and y dimensions.  On the ship there is also curvature in the z dimension.  The shell plating expansion is at best a general guide to the individual plate shape.  The modeler will need to develop the true shape of individual plates directly on the ship.  The advantages of this drawing are that it shows all the seams, butts and doubling in one drawing.  As an aid to the modeler, notations have been added which show how an individual plate or strake is overlapped or overlaps those adjacent to it.

Addenda

From time to time information comes to light which requires that one or more of the plan sheets be changed.  This section will display changes which are more than merely minor drafting errors.   All changes will be made to the plan sheets from the date of the change noted here forward.

 

1.  Date of change: 05/20/2011

Plan sheets affected: TI3, TI5

Nature of change:  Recent evidence has come to light from the Titanic wreck which shows an unidentified object on the aft inboard aspect of the port B deck #4 hatch.  This object had been seen for some time in later photos of Olympic.  After this wreck discovery, early Olympic photos showed the same object.  The quality of the photos is not good enough to show all the details of the object.  I have added it to the plans and have interpreted the photos as best I could.  If better photos surface I will again update the drawings.  The function of this object is not known at present but I have theorized what I believe it may be in an article here: Aft B deck mystery object

2. Date of change: 8/29/2011

     Plan sheet affected: TI6

    Nature of change:  This is a minor change.  The bulkhead lamp position on the starboard side of the first class entrance on the boat deck has been moved aft.  The Titanic photo of Jacques Futrelle shows that the lamp was not in the position previously    drawn.    The change is shown below.

3. Date of change: 9/19/2011

    Plan sheets affected: TI3, TI4, TI5, TI6

Nature of change:

Forward of Funnels 1, 2, and 3 on the port side is an access hatch to the fidley vents.  Recent study of archival and wreck photos have led me to alter the size and position of these hatches.  The new positions which are identical for all three boiler casings is shown in the drawing below.

4. Date of Change: 11/20/2011

Plan Sheets affected: TI1, TI2, TI6

Nature of Change:

Recent evidence has been discovered which may clarify our understanding of Titanic’s wheelhouse.  The evidence is a photo of Olympic’s wheelhouse in 1915.  This configuration represents changes which were made in Olympic’s 1912/13 refit.  These modifications changed Olympic’s officer’s quarters and wheelhouse to a configuration much like Titanic’s.  The aforementioned photo is shown below.

Olympic1

 

What we see is that the wheelhouse door is located aft very close to the officers’ quarters forward bulkhead.  We also see the incorporation of a circular window in the door which she did not previously have before her refit.  A photo still taken from a 1920’s film of Olympic (below) shows that the side window forward of the door is further aft than originally believed because it isn’t visible in this photo.

Olympic2

It appears that the window would be located just forward of where the door would open against the bulkhead.  The storm rail could not encroach aft on the bulkhead where the door opened.  Most likely the forward extent of the rail extends only to the forward extent of the the window since the forward extent of it is not seen in the 1920’s Olympic photo.  Re-examination of the 1920’s Olympic photo and the only known photo which shows Titanic’s wheelhouse (below) indicates that the forward corners of the wheelhouse were not the large 12 inch radius corners seen in some Olympic deck plans.

Titanic bridge

While the corners aren’t sharp, they appear to have not much more than a 1 inch corner radius.

The drawings below show the previous and revised drawings of wheehouse and its associated structures which have been modified by better evidence.

Drawing1

Drawing2

It is my opinion that the revised arrangement shown above more closely represents the actual arrangement than the earlier version.  Since we don’t, and probably won’t, have an actual photo of the area on Titanic, about the best we can do is make educated extrapolations from Olympic evidence.  It is also true that nothing in the new evidence can absolutely rule out other versions of this area for Titanic.  But I do believe the recent evidence brings us closer to the truth.

5. Date of Change: 10/27/2012 Note: this change was made during the Titanic Cad Plans hiatus period.  This date is being given to indicate that plans sold after this date will have this change incorporated.

Plan sheets affected: TI1, TI2, TI3, TI4

Nature of Change: The cowl vent on the port forecastle (Vent #1 on sheet TI4)  has been moved one frame interspace aft.  This cowl used to be centered between frames 113F and 114F.  It is now centered between 112F and 113F.  It still retains its perpendicular distance from the breakwater.  The drawing below illustrates this minor change.

6. Date of Change: 10/27/2012 Note: This change was made during the Titanic CAD Plans hiatus period.  The date is being given to indicate that plans sold after this date will have this change incorporated.

Plan Sheets Affected: TI1, TI2, TI3

Nature of Change:  The first pair of funnel shrouds aft of the forwardmost pair of the second funnel have been moved aft.  The original rigging plan showed the these shrouds at the more forward position.  Photo analysis has confirmed that the position where the pair of shrouds is belayed is just aft of the aft arm of the #7 and #8 davit positions.  The drawing below shows this minor change in shroud position.  Only the starboard shroud is shown in this drawing.  The port shroud is its mirror image.

7. Date of Change: 10/27/2012 Note: This change was made during the Titanic CAD plans hiatus period.  The date is being given to indicate that plans sold after this date will have this change incorporated.

Plan Sheets Affected: TI3, TI5

During recent research I discovered that of the two Trotman’s type anchors on Titanic their positions were reversed.  The 1 ton anchor was on the forecastle and the 1/2 ton anchor was on the poop.  This change just involves switching the locations of these two anchors from where they were originally shown.  The drawing below shows the two anchors as they now appear on plan sheet TI5.

addenda3

8. Date of Change: 7/17/13

Plan Sheets Affected: TI5

Nature of Change: Recent research has revealed that a change was necessary in the riveting pattern on the funnels.  Previously documents had indicated that there were 18 divisions between the rows of rivets.  Study of actual photographs have now confirmed that there are only 15 divisions.  There is a riveting division on the fore and aft midline on the aft face of the funnels.  On the fore and aft midline on the forward face of the funnels the riveting divisions are equally spaced on either side of the midline.  The image below is the updated drawing which is now shown on plan sheet TI5.

9. Date of Change: 7/30/2013

Plan sheets affected: TI3, TI4, TI5, TI6

Nature of Change:  Rather than being a new discovery, this change represents a confirmation of  previous information.  The Olympic Class Boat Deck Iron plan showed the wooden portion of the bridge front with a slight curvature limited to the area of the outboard window on both port and starboard.  The amount of curvature was noticed on the plan but there were indications on the plan which raised the possibility that it could have been altered in the “as built” version.  Photos of the Olympic class ships appeared to show a completely flat wooden bridge front.  Recently a photo of Titanic was located which finally and definitively confirmed the slight curvature shown in the Boat Deck Iron plan.  The photo in question is shown here.

Bridge

Of the nine windows which comprise the bridge front, the inboard seven which are in the flat section are all the same width in the photo.  The port side most outboard window is wider than the others whereas the starboard side most outboard window is narrower.  This is evidence that these two windows had their outboard edges angled aft.  The angle is only approximately five degrees.  This also means that the aft edge of the most outboard windows is only about three inches aft of the forward edge.  To illustrate how minor this change is, the previous plan drawing of this area is shown along with the current plan change.  Only the change to plan sheet TI6 is shown because it is the one which shows construction of the bridge area.

10. Date of Change: 9/7/2013

 

Sheets Affected: TI1, TI2, TI3, TI4, TI5

 

Nature of Change: Addition of Welin Davit Drawings.  When my plans were developed some areas had equipment for which no dimensional references were available.  The Welin Davits were in this category.  There were patent drawings but I had no confidence that the davits shown in the patent drawings were the models used on Olympic and Titanic or Britannic.  Recently I was provided blueprints of the original davits and documentation proving that they were the model used on Olympic, Titanic, and Britannic.  Since the original drawings were developed by photo analysis and from the rigging plans, I decided to make new drawings of the davits.   The original drawings were fairly close.  There is about a 10 inch difference in the height (shorter) of the new davit drawings.  On a 1/144 model this would translate to a davit which is less than 1/16 of an inch shorter.  New drawings on the plan sheet TI5  are shown below.

11. Date of Change: 9/25/2013

Plan Sheets affected: TI5

Nature of Change: Further study of the Welin Davits aboard Olympic reveals that the davit arms came in two versions, right and left.  In the pics below

the designations of right and left have to do with the location of the davit arm when looking outboard.

14. Date of Change: 1/14/2014

Sheets Affected: TI3, TI4 TI5

Nature of Change:  It has recently come to my attention that there were a couple of inaccuracies in my drawings of the 1-1/2 ton A deck cranes.  Changes were confirmed by photo analysis.  Changes made were:  Operator’s platform shape was changed and the number of diagonal struts in the crane jib was changed.  Changes are illustrated below.

15. Date of Change: 5/17/2014

Sheets Affected: TI1,TI2, TI3, TI5

Nature of Change:

It has been discovered that the positions of the davits were slightly different than originally thought.  I have written an article describing the changes in depth here: http://www.titanic-cad-plans.com/davit_new_understanding.pdf?9d7bd4  The article goes into depth about how the changes were determined but the modeler may want to skip to the summary table to see the changes.  All distances given in the table are full scale.  As you can see, on a scale model they would be very minimal.

No drawings are given for this change because the shifts in the locations of the davits are very minor.  The modeler can decide for himself whether it is desirable to make these changes at all.

16. Date of Change: 5/20/2014

Sheets Affected: TI2, TI4

Nature of Change:

Recently it was discovered that the intake duct of the ventilator on the forward port side of the raised roof over the first class lounge was not a swan neck duct of the type found on most of the 35 in. fans.  Instead it was of the type found on the 35 in. fan on the port roof of the Tank Room.  This was discovered in an O’Dell photo indicated with an arrow.

17. Date of Change: 6/10/2014

Sheets Affected: TI1, TI2, TI5

Nature of Change:  I have found that the lowest planking strake of all lifeboat types nearest the keel (garboard strake) did not have a sharp angle on its aft lower edge where it met the sternpost but rather this edge was rounded.

 Addendum8

18. Date of Change: 6/19/2014

Sheets Affected: TI1, TI2, TI3, TI4, TI5

Nature of Change: The first shrouds (port and starboard) aft of the forwardmost shrouds of the fourth funnel were found to have their deck belaying point aft of what was previously shown in the plans.  The previous and corrected versions are shown below.

 20. Date of Change: 6/23/2014

Sheets Affected: TI5

Nature of Change: Recently uncovered photo evidence has shown that the previous understanding of the capacity plates on the inboard bow of the wooden lifeboats was in error.  It was thought that the third line of the capacity plate indicated the occupant capacity.  It is now known that the third line actually indicated the cubic foot capacity of the boat.  The capacity plates (formerly referred to as draft plates) have been modified to reflect the change.  Also the typeface has been modified to reflect the style of the originals.  The  notation of “10x original size” only applies to that shown on the plans.

Addendum14

 

21. Date of Change: 8/26/2015

22. Date of Change: 1/1/2015

Sheets Affected: TI3, TI4, TI5, TI6

Nature of Change:  Recently the Boat Deck Iron Plan of Olympic was re-examined with regard to the dimensions of the wingcabs.  The dimensions were found to be 7 ft. in the fore and aft dimension and 6 ft. in the inboard to outboard dimension.  The roof overlaps by 3 in.   Photos were analyzed and it was found that Titanic’s wingcabs had the same dimensions but were just moved outboard from the positions of the original Olympic wingcabs.  The dimensions are shown in the drawing below.

Wingcab140001

23. Date of Change: 1/13/2016

Sheets Affected: TI3, TI4,TI5

Nature of change: The large 35 inch Sirocco ventilator fans on the raised roof over the lounge had output ducts which were higher than the deckhouses into which they ducted.  On later Olympic they solved the problem by using angled ducts to duct into the deckhouses below the moulding.  It was thought that they used the same angled ducts on Titanic.  However, recent analysis of photos and wreck images shows that they used a different solution.  They ducted the 35 in. fans directly into the deckhouses but they compensated for the height difference by the use of a hooded duct as part of the deckhouse.  In the ventilator inventory on Plan Sheet TI4 the affected 35 in. ventilators are numbers 31, 35, 41, 45.  The drawings below show ventilator #35 which is the 35 in. ventilator aft of funnel #2 just to starboard of the stokehold vent aft of funnel #2.  The view is from starboard looking to port.  There is also a magnification of the hooded duct extension on the deckhouse roof.  The dashed lines in the close-up view show the extent of the duct below the moulding.

25.  Date of Change: 2/3/2016

Sheets Affected: TI5

Nature of Change:  This is really an addition more than a change.  On sheet TI5 I have included a drawing of a 3 bladed center turbine propeller with a diameter of 17 ft.  Documentation has been found which shows that Titanic was to be fitted with such a propeller.  I was skeptical about this at first but after doing some more research, I now believe that it is more likely than not that Titanic’s center propeller was 3 bladed and was 17 ft. in diameter.  At this point there is not concrete proof whether the center propeller was 3 or 4 bladed.  Nearly all models and plans show a 4 bladed propeller but the only thing we had to go on was Olympic evidence.  With the more recent evidence I believe this was the most likely center propeller used on Titanic.  It was Mark Chirnside who discovered this information and wrote an article about it here: Titanic center propeller article

Sheets Affected: TI3, TI4, TI5, TI6

Nature of Change:  New information shows that the skylights over the officers’ lavatory and Marconi room had a slightly different configuration that was previously shown.  Evidence shows that the skylights had one hinged panel (sash) on each side of the skylight rather than two hinged panel per side.  The protective bars of the glass panes were completely within the frames of the panes.  The drawing below shows the minor changes.

30. Date of Change: 4/20/2016

Sheets affected: TI5

Nature of Change: A previously unknown photo has been published which shows one of Titanic’s Engelhardt collapsible lifeboats being recovered post-sinking by RMS Oceanic.  It clearly shows the entire interior of the boat.  It shows 4 thwarts for this boat rather than the 3 which previously appeared on the plan.  It is doubtful that this will make much difference to most modelers because I don’t think I have ever seen one of the collapsibles modeled without its boat cover.

32. Date of Change: 4/28/2016

Sheets Affected: TI4, TI3

Nature of change:  Film evidence has shown that Vent #25 which is the 35 in. sirocco ventilator fan inboard of the first class entrance on the port side of the boat deck has an extension from the fan to the deckhouse.  This extension was necessary because the fan had to be moved away from a waterway at the foot of the bulkhead.

33. Date of Change 2/8/2016

Sheets Affected: TI6

Nature of change: There should be no railings on the roof of the deckhouse under the fourth funnel forward of the funnel.  Many of the individual drawings of this particular plan sheet were adapted from Olympic drawings and it was an oversight not to remove the forward deckhouse roof railings.

34. Date of Change: 5/15/2016

Sheets Affected: TI3, TI4, TI5, TI6

Nature of Change:  Closer examination of Titanic wreck images has necessitated a modification of the fidley gratings.   The forward gratings have had the inboard angled corner modified.  Both the forward and aft gratings have had the athwartship stabilization bar modified in its shape and position.

35. Date of Change: 5/27/2016

Sheets Affected: TI3, TI4, TI5, TI6

Nature of Change:  Recent study of Titanic wreck photos shows that the fidley vent screens forward of the first funnel did not have angled inboard corners.  They were rectangular.  This does not affect the fidley vents of the other funnels.

36. Date of Change: 8/5/2016

Sheets Affected TI3, TI5

Nature of Change: It has been discovered that a notation on the Titanic Rigging Plan indicates that there were fall boxes to receive the ends of the falls for the emergency cutters.  They were inboard of the bulwark next to the emergency cutters.  They had to be situated so as not to interfere with the operation of the sounding machines.

37. Date of Change: 12/7/2016

Sheets Affected: TI3, TI9

Nature of change:

Additional research has revealed that the junctions of the keel plate to the stem and stern were in error on the drawings.  The transitions were created without any plate laps or interruptions.  The transition from the keel to the stern frame was accomplished by a tail piece which widened slightly from the width of the keel plate to the stern frame.  The transition from the keel plate to the stem bar was accomplished by a head piece which narrowed from the width of the keel plate to the width of the stem bar.  Figure 1 shows the transition at the stern.  The red area shows the slight widening where the keel plate meets the stern casting.  Figure 2 shows the transition at the stem.  The red area shows the narrowing where the keel plate meets the stem bar.

Sheets Affected: TI3, TI4

Nature of Change:  Recent research on Britannic and Olympic suggests that the intakes for a number of 35 inch sirocco electric fans which did not have intake ducts were protected with intake guards.  The change affects 5 ventilators shown in the the first drawing below shown in red.  The second drawing shows one of the ventilators with the intake guard shown in red.  This change was explained in more detail in a recent research article I wrote here: http://www.titanic-cad-plans.com/wp-content/uploads/2010/06/Intake-Guards-for-Titanic.pdf
