📌 Built as the largest and most advanced ocean liner of its time, Titanic’s luxury, engineering prowess, and White Star Line dominance in transatlantic travel were overshadowed by its infamous sinking on its maiden voyage. This comprehensive analysis of Titanic’s construction exposes both its strengths and fatal weaknesses.

The White Star Line

The Titanic, a significant part of the White Star Line's fleet, was one of 13 ships engaged in the transportation of passengers, mail, and cargo between Great Britain and the United States. The usual ports of call for this service were Southampton, Cherbourg, Plymouth, Queenstown, and New York.

The White Star Line, also known as the Oceanic Steam Navigation Co. (Ltd.), is the owner of the Titanic. This British registered company has a capital of £750,000, all paid up. The directors are Mr. J. Bruce Ismay (chairman), the Right Hon. Lord Pirrie, and Mr. H. A. Sanderson.

In addition to the Titanic, the company owns 29 other steamers and tenders, and has a significant interest in 13 other steamers. It also owns a training sailing ship for officers.

All the shares of the White Star Line, except eight shares held by Messrs. E. C. Grenfell, Vivian II, Smith, W. S. M. Burns, James Gray, J. Bruce Ismay, H. A. Sanderson, A. Kerr, and the Right Hon. Lord Pirrie, have, since the year 1902, been held by the International Navigation Co. (Ltd.), of Liverpool, a British registered company, with a capital of £700,000, of which all is paid up, the directors being Mr. J. Bruce Ismay (chairman), and Messrs. H. A. Sanderson, Charles F. Torrey, and H. Concannon.

The company's debentures, amounting to £1,250,000, are held primarily, if not entirely, by the general public in the United Kingdom. This financial stability underscores the company's strong investment potential.

The International Navigation Co. (Ltd.) of Liverpool, in addition to holding the shares mentioned above of the Oceanic Steam Navigation Co. (Ltd.), also holds a diverse portfolio of ownership, adding an intriguing dimension to its business strategy.

• Practically all of the issued share capital of the British & North Atlantic Steam Navigation Co. (Ltd.) and the Mississippi & Dominion Steamship Co. (Ltd.) (the Dominion Line).
• Practically all of the issued share capital of the Atlantic Transport Co. (Ltd) (the Atlantic Transport Line).
• Practically all of the issued ordinary share capital and about one-half of Frederick Leyland & Co. (Ltd.) preference share capital (the Leyland Line).

As against the shares mentioned above and other property, the International Navigation Co. (Ltd.) has issued share hen certificates for £25,000,000.

The International Navigation Co. (Ltd.) shares and share lien certificates are now held by the International Mercantile Marine Co. of New Jersey or by trustees for the holders of its debenture bonds.

The Steamship Titanic

The Titanic was a three-screw vessel with a gross tonnage of 46,328 and a net register tonnage of 21,831, built by Messrs. Harland & Wolff for the White Star Line service between Southampton and New York.

She was registered as a British steamship at the port of Liverpool, her official number being 131,428. Her registered dimensions were:

The propelling machinery consisted of two sets of four-cylinder reciprocating engines, each driving a wing propeller and a turbine driving the center propeller. Its registered horsepower was 50,000.

The propelling machinery of the Titanic was not just impressive in its current state, but also had the potential to develop even more power. The estimated power it could have developed was at least 55,000, a testament to its capabilities.

The structural arrangements of the Titanic were a key aspect of its design. These arrangements primarily consisted of:

• The Titanic's structure was fortified by an outer shell of robust steel plating, shaping the ship up to the top decks.
• Steel decks.—These were enumerated as follows:

Decks C, D, E, and F were continuous from end to end of the ship. The decks above these were constant for the greater part of the ship, extending forward and aft from amidships.

The boat deck and A deck each had two expansion joints, which broke the strength continuity. The decks below were continuous outside the boiler and engine rooms and extended to the ship's ends.

None of these Deck's steel parts, except the weather deck and watertight deck aft, were watertight except in small patches.

Transverse vertical bulkheads.—There were 15 transverse watertight bulkheads, by which the ship was divided in the direction of her length into 16 separate compartments. These bulkheads are referred to as "A" to P," commencing forward.

The bulkheads' watertightness extended to one or other of the decks D or E; bulkhead A extended to C but was only watertight to the D deck.

The position of the D, E, and F decks, which were the only ones to which the watertight bulkheads extended, was in relation to the water line (34 feet 7 inches draft) approximately as follows :

These were the three of the four decks which, as already stated, were continuous all fore and aft. The other decks, G, and Orlop, which extended only along a part of the ship, were spaced about 8 feet apart.

The G deck forward was about 7 feet 6 inches above the water line at the bow and about level with the water line at bulkhead D, which was at the foreend of the boilers.

The G deck aft and the Orlop deck at both ends of the vessel were below the water line. The Orlop deck abaft of the turbine engine room and forward of the collision bulkhead was watertight.

Elsewhere, except in very small patches, the decks were not watertight. All the decks had large openings or hatchways in each compartment so that water could rise freely through them.

There was also a watertight inner bottom, or tank top, about 5 feet above the top of the keel, which extended for the full breadth of the vessel from bulkhead A to 20 feet before bulkhead P, i.e., for the whole length of the vessel except a small distance at each end.

The transverse watertight divisions of this double bottom practically coincided with the watertight transverse bulkheads; an additional watertight division was under the middle of the reciprocating engine room compartment (between bulkheads K and L).

The double bottom had three longitudinal watertight divisions: one at the center of the ship, extending about 670 feet, and one on each side, extending 447 feet.

All the transverse bulkheads were carried up watertight to at least the height of the E deck. Bulkheads A and B, and all bulkheads from K (90 feet abaft amidships) to P, both inclusive, further extended watertight up to the underside of D deck. A bulkhead extended to the O deck but was watertight only to the D deck.

Bulkheads A and B forward and P aft had no openings. All the other bulkheads had openings, which were fitted with watertight doors. Bulkheads D to O, both inclusive, each had a vertical sliding watertight door at the level of the floor of the engine and boiler rooms for the use of the engineers and firemen.

On the Orlop deck, one door on bulkhead N allowed access to the refrigerator rooms. There were no watertight doors on the G deck. On both the F and E decks, nearly all the bulkheads had watertight doors, mainly for communication between the different blocks of passenger accommodation.

All the doors, except those in the engine rooms and boiler rooms, were horizontal sliding doors that could be operated by hand, both at the door and on the deck above.

The boiler and engine rooms had 12 vertical sliding watertight doors, which completed water tightness D to O, inclusive. These doors could be closed from the bridge, and the closing operation was intended to be preceded by the ringing of a warning bell from the bridge.

These doors were closed by bringing an electric current into operation. They could only be opened once this current was cut off from the bridge. When this was done, the doors could only be opened manually by a mechanical operation working separately at each door.

However, they could be individually lowered again by operating a lever at the door. If open, they would be automatically closed should water enter the compartment.

This operation was done in each case by means of a float actuated by the water in either of the compartments that happened to be flooded.

There were no sluice valves or means of letting water from one compartment to another.
