Wheelhouse

Information about Wheelhouse

Bridge of the tugboat Leao Dos Mares. An open compass platform, which still has the traditional binnacle, now also houses a radar antennae and sits above the enclosed wheel house. The circular devices in the windows are Kent screens; discs that rotate at high speed to provide a clear view, whatever the weather.

The bridge of a ship is an area or room from which the ship can be commanded. When a ship is underway, the ship's captain or a senior officer is on the bridge at all times to maintain command and control.

Evolution

Traditionally, in sailing ships, the ship would be commanded from the poop deck, right aft. With the arrival of paddle steamers, engineers required a platform from which they could inspect the paddle wheels and the captain required a position where his view would not be obstructed by the paddle houses. A raised walkway, literally a bridge, connecting the paddle houses was therefore provided. When the screw propeller superseded the paddle wheel, the bridge was retained.

Traditionally, commands would be passed from the senior officer on the bridge to stations dispersed throughout the ship, where physical control of the ship was exercised, as technology did not exist for the remote control of e.g. steering or machinery. Helm orders would be passed to an enclosed wheel house, where the coxswain or helmsman operated the ship's wheel. Engine commands would be relayed to the engineer in the engine room by an engine telegraph, which displayed the captain's orders on a dial. The engineer would ensure that the correct combination of steam pressure and engine revolutions were applied to enact his orders. The bridge was often open to the elements, therefore a weatherproof pilot house could be provided, from where a pilot (traditionally, the pilot was the ship's navigating officer) could issue commands from shelter.

The compass platform of a British destroyer in the Battle of the Atlantic during the Second World War. Notice the binnacle in the prominent position centrally and the voice pipes for relaying commands. The armoured wheelhouse and the coxswain would be directly underneath. The Royal Navy favoured the open bridge for the unique tactical view it gave the Captain, long after other navies had moved indoors.

Iron, and later steel, ships also required a compass platform. This was usually a tower, where a magnetic compass could be sited as far away from the ferrous interference from the hulk the ship. Depending upon the design and layout of a ship, all of these terms can be variously interchangeable.

Larger ships, particularly warships, often had a number of different bridges. A navigation bridge would be used for the actual conning of the ship. A separate Admiral's bridge could be provided in flagships, where the Admiral could exercise strategic control over his fleet without interfering with the Captain's tactical command of the vessel. In older warships, a heavily-armoured conning tower was often provided, where the vital command staff could be located under protection to ensure that the ship could be commanded and fought under fire.

Modern advances in remote control equipment has seen progressive transfer of the actual control of the ship to the bridge. The wheel and throttles can be operated directly from the bridge, directly controlling often-unmanned machinery spaces.
