VTS Emergency and Contingency Procedures Questions and Answers — Questions and Answers
Question 1: A VTS operator observes a tanker on radar suddenly stop, and shortly after receives a report from a nearby vessel of a visible sheen on the water around the tanker's position. What is the VTS operator's most critical immediate responsibility after acknowledging the report?
- Instruct the tanker to immediately proceed to a designated anchorage.
- Request all vessels in the vicinity to assist in containing the spill.
- Implement the local VTS pollution response contingency plan and notify the designated authorities. (Correct answer)
- Immediately broadcast a PAN PAN message on the VTS working channel and VHF Channel 16.
Correct answer: Implement the local VTS pollution response contingency plan and notify the designated authorities.
The VTS operator's primary role in a pollution incident is to activate the established contingency plan, which includes notifying the appropriate authorities, such as the port authority, coast guard, or marine pollution control unit. While broadcasting warnings is important, the official notification is the critical first step to initiate a formal response.
Question 2: A VTS operator receives a MAYDAY RELAY from a vessel that has overheard a distress call. The VTS has not heard the original distress call directly. What is the operator's first action according to standard procedure?
- Acknowledge receipt of the MAYDAY relay and immediately inform the appropriate Rescue Coordination Centre (RCC). (Correct answer)
- Immediately assume control as the on-scene coordinator for the SAR incident.
- Instruct the relaying vessel to proceed to the distress position and report back.
- Acknowledge the MAYDAY relay and then re-broadcast it on all available channels.
Correct answer: Acknowledge receipt of the MAYDAY relay and immediately inform the appropriate Rescue Coordination Centre (RCC).
The VTS serves as a vital communication link to the official Search and Rescue (SAR) organization. The first and most crucial step is to pass the distress information to the Rescue Coordination Centre (RCC), which is responsible for coordinating the SAR response. Assuming control or re-broadcasting without RCC direction would be incorrect procedure.
Question 3: Which of the following is the most essential element of a VTS Centre's contingency plan for a complete power failure?
- A procedure for notifying all vessels in the VTS area of the service outage.
- A manual logbook and plotting charts to track vessel movements.
- A list of senior management to be contacted in order of priority.
- A backup power source, such as an Uninterruptible Power Supply (UPS) and a generator, capable of supporting critical systems. (Correct answer)
Correct answer: A backup power source, such as an Uninterruptible Power Supply (UPS) and a generator, capable of supporting critical systems.
While all listed items are part of a comprehensive contingency plan, the most essential element for maintaining any level of service is a reliable backup power source. An Uninterruptible Power Supply (UPS) provides instant power to bridge the gap until a generator starts, ensuring that critical systems like communications and surveillance do not shut down abruptly.
Question 4: A VTS receives a forecast for a rapidly approaching hurricane, and the VTS Centre's heavy weather contingency plan is activated. Which action is a primary responsibility of the VTS operator under these circumstances?
- Ordering all vessels to evacuate the port immediately.
- Broadcasting severe weather warnings and advising vessels of port-specific heavy weather procedures. (Correct answer)
- Suspending all VTS operations until the storm has passed to ensure operator safety.
- Directing specific vessels to sheltered anchorages based on their size and type.
Correct answer: Broadcasting severe weather warnings and advising vessels of port-specific heavy weather procedures.
The VTS's primary role is to provide an Information Service (IS), which is critical during severe weather. This includes broadcasting warnings, updates, and information about the port's established heavy weather plan (e.g., port closures, anchorage assignments from the Harbour Master). A VTS operator advises and informs but does not typically hold the authority to order evacuations, which rests with the Competent Authority (like a Port Captain or Harbour Master).
Question 5: During a Search and Rescue (SAR) operation being managed by a Rescue Coordination Centre (RCC), what is the primary role of the VTS?
- To take over as On-Scene Coordinator (OSC) from the RCC.
- To suspend all other vessel traffic within the VTS area until the SAR operation is complete.
- To provide the RCC with a real-time traffic image and facilitate communication with vessels in the vicinity. (Correct answer)
- To direct the search patterns of all participating SAR units.
Correct answer: To provide the RCC with a real-time traffic image and facilitate communication with vessels in the vicinity.
The VTS acts in a support role to the RCC during SAR operations. Its key assets are its surveillance systems (radar, AIS) which create a comprehensive traffic image, and its communication capabilities. The VTS uses these assets to provide the RCC with vital information and to help coordinate communications with vessels that may be able to assist. The RCC remains in overall command of the SAR incident.
Question 6: A vessel within a VTS area is not responding to repeated calls and is deviating from its sailing plan, creating a risk to other traffic. After exhausting standard communication attempts, which of the following is an appropriate next step for the VTS operator as part of a contingency procedure?
- Request immediate intervention from maritime law enforcement or Coast Guard patrol assets. (Correct answer)
- Broadcast a SECURITE message warning other traffic of the vessel's unpredictable behavior.
- Instruct another vessel in the vicinity to intercept the non-compliant vessel.
- Immediately de-activate the vessel's AIS transponder remotely to reduce screen clutter.
Correct answer: Request immediate intervention from maritime law enforcement or Coast Guard patrol assets.
When a vessel is non-responsive and poses a potential safety or security threat, the situation escalates beyond the normal advisory capacity of a VTS. The proper contingency procedure is to notify and request assistance from the authorities with enforcement powers, such as the Coast Guard or maritime police. While broadcasting a warning is also a good practice, involving enforcement is the critical step for a potentially rogue vessel.
