Hydraulic steering gear is a mechanical system that is used to control the direction of a ship or other large vessel. It is a complex system that uses hydraulic pressure to turn the rudder, which in turn steers the vessel.

The hydraulic steering gear consists of several components, including a hydraulic pump, hydraulic hoses, a steering cylinder, and a control valve. The hydraulic pump is typically driven by the ship's main engine or an auxiliary engine, and it generates hydraulic pressure that is used to power the steering system.

The hydraulic hoses carry the pressurized fluid from the pump to the steering cylinder, which is connected to the rudder. The control valve regulates the flow of fluid to the steering cylinder, allowing the helmsman to control the direction of the vessel by turning the wheel or joystick.

When the helmsman turns the wheel or joystick, the control valve directs the pressurized fluid to one side of the steering cylinder, which pushes the rudder in the opposite direction. This causes the vessel to turn in the desired direction. The hydraulic pressure generated by the pump is strong enough to turn the rudder even in high winds and rough seas, making it a reliable and effective method of steering large vessels.

Hydraulic steering gear is valued for its precision, power, and reliability. It allows ships to be maneuvered with ease, even in challenging conditions, and it is essential for safe and effective navigation. However, it requires regular maintenance and inspection to ensure that all components are in good working order and to prevent malfunctions that could lead to accidents or damage to the vessel.

Overall, hydraulic steering gear is a critical component of any large vessel, providing a reliable and efficient way to control the direction of the vessel and ensure safe navigation.
