Understanding WCL (SSSV) in Hold: A Guide to Controlling Line Communication
In the world of maritime operations, efficient and controlled communication is paramount. This is especially true when a vessel is in a “hold” state, waiting for instructions or clearance. To ensure smooth operations and prevent confusion, a specific communication protocol is employed: WCL (SSSV).
WCL (SSSV) stands for “Watch Keeping and Line Control (Single Ship Supervision System). It's a system used by vessels to control and manage communication while in a hold state. This system plays a critical role in:
- Minimizing Radio Traffic: It eliminates unnecessary communication by providing a single point of contact for all relevant information.
- Maintaining Order and Clarity: By implementing a structured system, WCL (SSSV) ensures that information is conveyed accurately and efficiently.
- Preventing Confusion and Misunderstandings: It creates a clear chain of command and eliminates the potential for conflicting instructions.
Here’s a breakdown of how WCL (SSSV) functions:
- Single Point of Contact: The vessel's designated "Watch Keeper" acts as the primary communication channel. They receive all instructions and relay them to the relevant personnel on board.
- Structured Communication: The Watch Keeper uses specific phrases and terminology to ensure clarity and eliminate ambiguity.
- System for Recording and Reporting: A record of all communication and decisions is maintained, providing a transparent and accountable system.
Key benefits of using WCL (SSSV) in Hold:
- Improved Safety: Reduced radio traffic and clear communication decrease the potential for misinterpretation and errors.
- Increased Efficiency: Streamlined communication leads to faster response times and efficient handling of vessel operations.
- Enhanced Control: The system provides a centralized point of control, ensuring that all communication is managed effectively.
- Reduced Stress: Clear communication and a structured process help alleviate stress for crew members.
In Summary:
WCL (SSSV) is a vital tool for managing line communication while a vessel is in a hold state. It ensures clarity, order, and efficiency, contributing to a safer and more effective operation. Understanding and adhering to the WCL (SSSV) protocol is crucial for all personnel involved in maritime operations, especially when dealing with vessel holds.

WCL (SSSV) Exercise:
Scenario: A vessel is in a hold state waiting for clearance to enter a port. The Watch Keeper receives the following instructions from the port authority via radio:
"Vessel [Vessel Name], you are cleared to enter port. Please proceed at 5 knots and maintain a course of 270 degrees. Notify us when you have passed the red buoy."
Task:
Using WCL (SSSV), the Watch Keeper needs to communicate these instructions to the relevant personnel on board, ensuring clarity and accuracy. Write down the communication steps the Watch Keeper should take, using the correct phrases and terminology.
Exercice Correction
Here is a possible solution for the communication steps: **1. Acknowledgement:** > "This is [Vessel Name], acknowledging instructions." **2. Relaying Instructions:** > "Attention all crew, we have received clearance to enter port. Proceed at 5 knots and maintain a course of 270 degrees. Notify the Watch Keeper when passing the red buoy." **3. Confirmation:** > "Watch Keeper, I have relayed the instructions to the bridge team. They are ready to proceed as instructed." **4. Recording the Communication:** > "WCL log: [Date & Time] Instructions received from [Port Authority] regarding entry clearance. Instructions relayed to bridge team. Confirmed by bridge team." **Note:** The specific phrases and terminology used may vary depending on the company's communication protocols. The key is to maintain clarity and structure in the communication process.
