When launched, Titanic was the largest moving object built to date so she needed some impressive machinery to power her.
It was provided by two reciprocating steam engines used to drive the port and starboard wing propellers, plus a low-pressure steam turbine to drive the centre propeller.
This was robust technology, designed to deliver reliable service rather than set speed records. The engines were assembled in the engine works’ erecting shop then dismantled and the components were taken to the fitting out wharf.
