Reference Answer
### (a) Protections for Electrical Equipment of Ship's Steering Gear (SOLAS Ch II-1, Reg 29 & 30)
As a critical system for vessel safety, the electrical equipment for steering gear is subject to stringent protection and redundancy requirements mandated by SOLAS. The primary objective is to ensure continuous availability of steering control under all foreseeable circumstances, including single-point failures.
1. **Dual Exclusive Power Supply Circuits:**
* **Requirement:** Each electric or electro-hydraulic steering gear must be served by at least two independent and exclusive circuits. These circuits must originate directly from the main switchboard.
