Harland & Wolff: The Shipyard That Built Titanic – Engineering, Design, and Shipbuilding Innovations

📌 Explore the legacy of Harland & Wolff, the Belfast shipbuilders behind the Titanic and Olympic. Learn about their shipyard innovations, construction techniques, and the design philosophy that shaped the world’s greatest ocean liners. A must-read for maritime historians, educators, and genealogy researchers.

The builders of the Olympic and Titanic, the celebrated firm of Harland & Wolff, Limited, have had unrivalled experience in the construction of large passenger vessels, and the new White Star liners but add another triumph to the many which they have to their credit.

Unlike many shipbuilding firms, Messrs. Harland & Wolff may be termed builders in the most complete sense of the word. As in the case of all vessels built by them, not only have they constructed the hulls of the Olympic and Titanic, but also their propelling machinery, while much of the outfit usually supplied by sub-contractors for ships built in other yards has been manufactured in their own works.

A Brief Description of the Ship Joiner’s Work

The work of the ship joiner who is employed to install joiner work of a fire-proof nature involves knowledge of metal trim, ship hardware accessories, and methods of installing special metal fittings. The ship joiner must be able to read necessary blueprints, use certain woodworking and metalworking tools, and cooperate with other tradesmen.

The ship joiner's preliminary work is laying out the locations of the various rooms, as shown on the blueprint. Measurements are taken from ship center lines. When the locations of the multiple rooms have been laid out, the necessary work done by other craftsmen may begin. The pipe fitter, electrician, ship carpenter, sheet metal mechanic, and radio man all have work to do as soon as the ship joiner's work is ready for their services.

After the quarters are tested and the iron painted, the ship joiner installs the vertical and horizontal furring or groundwork. The services of the welder and the burner are required for this installation. Still, the joiner supervises the burning and welding to ensure the work is fair and straight. One of the first operations is to install the stairs, which provide easy access from one deck to another. This is done to make working conditions less hazardous by eliminating the necessity for ladders or scaffolding. Insulation of an approved type is installed correctly and secured in place.

Intermediate bulkheads are erected. The locations of the bulkheads establish the boundary lines for rooms, bathrooms, and passages, as well as the center lines for lighting fixtures and ventilators. When other artisans have finished their work, the joiner erects shell lining and ceilings and constructs the wardrobes. The erection of bulkheads and the installation of doors require the use of self-tapping screws and a knowledge of the proper sizes of drills to use when driving certain screws in metal.

Portlight frames are set, bathrooms, rooms, and wardrobes are trimmed with the correct metal trim and properly placed according to the blueprint. This work is different from when it was done entirely in wood.

After the floors are in place, wood or metal furniture, ajar hooks, bumpers, locks, coat hooks, rods, clock pads, notice frames, and many other metal accessories are installed. Boxes and lockers of various types are fastened to the steel deck.

The ship joiner also insulates and finishes the cargo holds and constructs and insulates the ship refrigerators.

This brief description of the work involved shows that the joiner must be able to adapt himself to working in either wood or metal. Although he encounters many problems, he must give his work a clean, neat appearance since this is one of the chief objectives in joiner work.

The Builders

The SS Olympic and SS Titanic were built by the renowned firm Harland & Wolff, Limited, which has unparalleled experience constructing large passenger vessels, including the new White Star liners. This latest achievement adds to the company's many successes.

Unlike many shipbuilding firms, Harland & Wolff are comprehensive builders. Both the SS Olympic and SS Titanic did not just construct the hulls but also the propelling machinery—much of the equipment that subcontractors in other shipyards typically supply was manufactured directly at Harland & Wolff facilities.

Most Important Design Factors

The two most important design factors are the speed and passenger accommodation to be aimed at. It has always been the endeavor of the competing steamship companies on the Atlantic to possess vessels that excel in one or both of these respects. The increase in the size of the ship favors both factors. Hence, the tendency to greater dimensions has been so marked during the past few years.

The maximum possible dimensions of a new vessel depend upon the dock and harbor accommodation available when the ship is completed. Lord Pirrie, among others, has devoted so much time and energy to the question of increased dock and harbor facilities, underscoring the crucial role of infrastructure in ship design and the maritime industry as a whole.

Reverting to the subject of speed, high speed is a very costly requirement, not only owing to the tremendous initial cost of the propelling machinery and the high cost of fuel on service but also on account of the necessary fineness of the ship, which limits the earning power as regards cargo-carrying and the extent of passenger accommodation.

The design difficulties significantly increase in a high-speed Atlantic liner, as the limited draught of water at the terminal ports handicaps the designer. 'Draught refers to the depth of a ship's hull below the waterline. Prudent consideration has to be given to the question of weight, as any saving that can be effected is of great value. If, on the other hand, a more moderate speed is aimed at, the problem of weight is much simplified, as the vessel can be built to a fuller model.

A greater displacement is secured without exceeding the draught available. It has been the custom of the White Star Line to strive for pre-eminence in passenger accommodation in conjunction with a speed that can be obtained without too great a sacrifice of cargo capacity, and the SS Olympic and SS Titanic have been designed under that policy.

Although a passenger on one of these vessels will not have the honor of crossing in the fastest ship on the Atlantic, he will have many compensating advantages regarding increased comfort at sea and the greater extent and variety of the accommodation provided.
