General View of Generating Plant. The main generating plant, which is probably the largest electrical equipment that has been installed up to the present for marine work, consists of four 400 kw. Engines and dynamos, manufactured by Messrs. W. H. Allen, Son & Co., of Bedford, and having a collective output of 16,000 amps. at 100 volts, thus exceeding in current capacity many electrical central stations. The Electrician (28 July 1911) p. 615.

One of the Main Generating Sets on the Olympic. The Electrician (28 July 1911) p. 617. GGA Image ID # 10f0a9c5e1

Main Switchgear of Dynamo Nos. 1 and 2. Each set of main switchgear is operated by a row of five interlocked handle levers. The two outer handles are connected mechanically with the lighting and power equaling switches, respectively, and are interlocked so that they must be closed before the next handles, which operate the lighting and power main bus-bar selector switches, can be worked. The central handle is for closing and gripping the circuit breaker, and is also interlocked with the selector switch handles, so that the circuit breaker can only be closed and gripped when the selector switches are both in the "off" position.

2 1/2 Ton Electric Crane. One of the little discomforts sometimes associated with modern ocean travelling is the noise caused by winches and other deck appliances, and although when on the high seas these are not much in evidence, yet when approaching port it is sometimes necessary to use them, as for instance when handling mails or passengers' luggage preparatory to dis embarkation. With a view to avoiding this on the “Olympic," the aid of electricity has again been invoked, with the result that all the winches in the vicinity of the passenger accommodation and the cargo cranes are electrically driven. The latter are made by Messrs. Stothert & Pitt, six having of 50 cwt. each, and two of 30 cwt. each. These cranes are fitted at the three after hatches and at the forward hatch near the passenger quarters. The Electrician (4 August 1911) p. 659. GGA Image ID # 1f8dba40e2

3-Ton Electric Cargo Winch. In addition to the electric cranes, there are four 3-ton electric cargo winches at the hatches, as well as four 15-cwt. electric boat winches made by the Sunderland Forge and Engineering Co. Ltd. The Electrician (4 August 1911) p. 659. GGA Image ID # 1f8dcf0600

Magneta Master Clock. The clocks, of which there are 48 throughout the vessel, are all actuated electrically, and worked in complete synchronism, so that each register exactly the same time; they are controlled by a master clock (Fig. 14) placed in the chart room under the control of the officers, who can set them backwards and forwards according to the longitude.

Marconi Apparatus in Operating Cabin. No modern liner is complete without a wireless telegraph installation. With such an equipment not only is communication with ship or shore possible in case of accidents, but the passenger is enabled during the voyage to keep himself in touch with the world's news. The “wireless " apparatus on the “Olympic '' is of the Marconi type and consists of a 5 kw. motor-generator set combined with the latest type of valve receiver installed as a standby. The installation is designed to provide, when employed with a suitable aerial having a mean height of 170 ft., a working range of 250 nautical miles over water, and a maximum range considerably exceeding the above figure. The Electrician (4 August 1911) p. 661. GGA Image ID # 10f2cc2d4c

View of the Starboard Reciprocating Engines on the RMS Titanic. It may be stated that both triple screw steamers Titanic and Olympic have propelling plants consisting of reciprocating engines and a low-pressure steam turbine. The two sets of reciprocating engines, one driving each wing shaft are of the four crank triple type and are arranged to work at 215 pounds per square inch and to exhaust at 9 pounds absolute.

The combination of reciprocating engines with a Parsons low-pressure turbine, which has been adopted for the propelling machinery of the Olympic and Titanic, is one of the latest examples of progress in marine engineering.

The superior economy of the system is due to the fact that increased power is obtained with the same steam consumption by expanding the steam in the low-pressure turbine beyond the limits possible with the reciprocating engine.

Messrs. Harland & Wolff were among the first to see the advantages of the combination arrangement and to put the system to the test of actual experience. This was done in the case of the Laurentic, already referred to, and the successful results obtained with this vessel led to the introduction of engines of the combination type in the new White Star liners and other vessels built and building at Belfast.

The refrigerating installation on board the Olympic and Titanic embodies all the latest facilities for efficient cold storage, ship’s provision rooms, situated aft on the lower and orlop decks (see Plate V: The White Star Triple-Screw Steamers "Olympic" and "Titanic." Deck Plans of Lower and Orlop), are most extensive, and include separate cold chambers for beef, mutton, poultry and game, fish, vegetables, fruit, milk and butter, bacon and cheese, flowers, mineral waters, wine and spirits, and champagne, which can thus be kept at the temperatures most suitable for preservation in each case.

ELECTRICITY, it need hardly be pointed out, is extensively employed in all the departments of the Olympic and Titanic. In addition to the large supply required for lighting purposes, electrical power is used for the deck cranes; cargo, boat, and engine room winches; passenger elevators; stores, mail, and pantry lifts; ventilating and stokehold fans; cabin fans; motors for the cylinder-lifting gear, turbine-turning and lifting gear, and condenser sluice valves; the workshop machine tools; conveyor for marconigrams; gymnastic apparatus; kitchen and pantry machinery, such as the ice-rocker, dough-mixers, potato-peelers, roasters, knife-cleaners, mincers, hot plates, and electric irons; electric heaters; electric baths; main steam whistles; sounding machines; stoking indicators; boiler room telegraphs; clocks; watertight doors; helm indicator; illuminated pictures; chimes; bells; loud-speaking and service telephones; submarine signaling; and wireless telegraphy.

The electrical installation, therefore, may virtually be termed the nerve system of the ship. Indeed the application of electricity is so general that much of the electrical equipment is necessarily described in the other sections of this book.

The working arrangements on board the Olympic and Titanic are necessarily on a scale in keeping with the great size of the vessels. The number of crew employed on board each ship for all purposes is about 860. Of these about 65 belong to the navigating department, 320 are employed in the engineers’ department, and 475 are engaged in the stewards’ and catering department.

The forward portion of the boat deck and the exposed decks at the ends of the vessel are entirely devoted to working and navigating appliances, while the management of the ship is also greatly facilitated by the working passage on the port side of E deck, which extends nearly the full length of this deck and is connected by stairways with all the principal departments.
