Titanic Images - The Shipbuilder - 4: Propelling Machinery

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.
