### (a) Safety Devices Provided on the Steering Gear System
The steering gear system is critical for a vessel's navigation and safety, and as such, it is equipped with numerous safety devices and features to ensure its reliable operation and prevent potential failures. These devices are designed to protect the system itself, the rudder, and ultimately, the safety of the vessel. The following are key safety devices:
* **Hydraulic Pressure Relief Valves:**
* **Purpose:** These valves are crucial for protecting the hydraulic system components (pumps, cylinders, piping, and rudder stock) from excessive pressure. They are typically set to relieve pressure if it exceeds a predetermined safe working limit.
