9.2.7 Emergency steering gear
Explain:
- Change over bridge control to local control in the steering gear compartment
- Standard emergency steering procedures
- Need for proper communication
Emergency steering gear is a crucial system on a vessel that allows for steering control in the event of a failure or malfunction of the primary steering system. In accordance with maritime regulations and best practices, the following technical explanations are provided:
Change over bridge control to local control in the steering gear compartment:
In the event of a failure or loss of control in the bridge steering system, it may be necessary to switch control to the emergency steering gear located in the steering gear compartment. This is typically achieved through the following steps:
Bridge Control Changeover: The bridge control system is disengaged or switched off, ensuring that commands from the bridge do not interfere with the emergency steering gear.
Local Control Activation: Local control of the emergency steering gear is activated in the steering gear compartment. This may involve manually engaging control levers or switches, depending on the specific design of the vessel's emergency steering system.
The changeover from bridge control to local control allows the vessel's crew to directly operate the emergency steering gear from the compartment, bypassing any issues or malfunctions in the bridge steering system.
Standard Emergency Steering Procedures:
Standard emergency steering procedures are established protocols that guide the crew in the operation of the emergency steering gear. These procedures may include:
Emergency Steering Team: Assigning specific crew members to form an emergency steering team responsible for operating the emergency steering gear and ensuring effective communication.
Equipment Readiness: Verifying that the emergency steering gear is in proper working condition, regularly maintained, and readily accessible.
Communication and Coordination: Establishing clear communication channels between the bridge, steering gear compartment, and other essential areas of the vessel. This allows for effective coordination and transmission of steering commands and feedback.
Training and Familiarization: Ensuring that crew members are adequately trained and familiar with the operation of the emergency steering gear. Regular drills and exercises should be conducted to enhance proficiency and response capabilities.
Monitoring and Feedback: Continuously monitoring the vessel's heading and response to steering commands. Feedback from the steering gear compartment should be promptly communicated to the bridge to maintain situational awareness.
These standardized procedures help to streamline the emergency steering process, enabling a coordinated and efficient response in steering emergencies.
Need for Proper Communication:
Proper communication is vital during emergency steering situations for several reasons:
Command Transmission: Effective communication ensures that steering commands from the bridge are accurately relayed to the crew operating the emergency steering gear.
Feedback and Status Updates: Communication allows for the transmission of feedback and updates on the status of the emergency steering operations, such as the vessel's response to steering commands or any issues encountered.
Coordination and Cooperation: Clear and concise communication fosters coordination and cooperation between the bridge, steering gear compartment, and other relevant areas, facilitating a synchronized and efficient response.
Emergency Notifications: In case of steering failures or emergencies, immediate communication with the appropriate authorities, such as the ship's master or the engine control room, ensures that appropriate actions can be taken promptly.
Proper communication protocols, including the use of standardized terminology and established channels, should be in place to ensure effective communication during emergency steering situations.
