Olympic and Titanic - Machinery Layout

Steering Compartment (Shelter Deck)

Electric Engine Room

The ship's rudder was moved by steam-powered steering gear mounted near the stern of the ship, beneath the poop deck. Also occupying this space were the capstan engines and other mooring and warping equipment. The capstan engines and the warping capstan shown here are loosely based on those of the liner Oceanic (1899). No photos or detailed plans of the Olympic-class capstan machinery are known to exist.

Details of the Wilson-Pirrie steering gear are shown here. The two steering engines were controlled from the navigating bridge by a hydraulic telemotor system, or from the aft docking bridge by mechanical shafting. Only one engine was used at a time, the other being taken out of gear by sliding it forward. The port-side engine (top) is shown here disengaged.
