VTS Safety Procedures 5 — Questions and Answers
Question 1: A vessel with dangerous cargo requests to transit a VTS area during a period of dense fog. What is the VTS operator's primary safety consideration?
- The vessel's schedule and commercial interests
- Visibility conditions, traffic density, and the risk posed by the cargo to other vessels and the waterway (Correct answer)
- Whether the vessel's pilot is certified for the port
- The vessel's flag state and insurance coverage
Correct answer: Visibility conditions, traffic density, and the risk posed by the cargo to other vessels and the waterway
The safety risk to the waterway from a dangerous cargo vessel in restricted visibility is the primary operational concern for VTS.
Question 2: What is the correct radio procedure for a VTS operator relaying a MAYDAY message on behalf of a vessel that cannot communicate?
- Call 'MAYDAY RELAY' three times, followed by 'ALL STATIONS' three times, then the message (Correct answer)
- Call 'PAN-PAN' to indicate the secondary urgency level
- Send the message by DSC only and await acknowledgment
- Contact the vessel's agent before broadcasting
Correct answer: Call 'MAYDAY RELAY' three times, followed by 'ALL STATIONS' three times, then the message
The MAYDAY RELAY procedure begins with 'MAYDAY RELAY' spoken three times, addressed to all stations, followed by the distress message details.
Question 3: Which of the following best describes the VTS operator's responsibility regarding a vessel that fails to report at a mandatory reporting point?
- The operator should log the failure and take no action until the next shift
- The operator should attempt contact, alert nearby vessels, and notify the appropriate SAR authority if contact is not established (Correct answer)
- The operator should issue a penalty notice to the vessel owner
- The operator should redirect all other traffic to avoid the vessel's last known area
Correct answer: The operator should attempt contact, alert nearby vessels, and notify the appropriate SAR authority if contact is not established
Failure to report at a mandatory point requires immediate contact attempts and SAR notification if the vessel cannot be reached.
Question 4: What is the purpose of a 'port state control' inspection in relation to vessel safety?
- To audit VTS operator performance
- To verify that foreign vessels comply with international safety and environmental conventions (Correct answer)
- To certify harbor pilots for specific vessel types
- To test VHF radio equipment on vessels entering port
Correct answer: To verify that foreign vessels comply with international safety and environmental conventions
Port state control inspections ensure foreign-flagged vessels meet international safety standards including SOLAS, MARPOL, and STCW.
Question 5: A vessel reports that its AIS transponder has failed. What are the VTS operator's expected actions?
- Deny entry to the vessel until AIS is repaired
- Note the failure, increase radar monitoring of the vessel, and inform other traffic as necessary (Correct answer)
- Immediately contact the flag state administration
- Transfer the vessel to a restricted anchorage area
Correct answer: Note the failure, increase radar monitoring of the vessel, and inform other traffic as necessary
AIS failure increases monitoring requirements; the VTS operator uses radar tracking and informs adjacent traffic of the reduced information availability.
Question 6: During a major maritime incident in a VTS area, which document guides the coordination of federal, state, and local response?
- The vessel's certificate of registry
- The National Incident Management System (NIMS) / Incident Command System (ICS) (Correct answer)
- The port's tariff schedule
- The vessel's safety management system manual
Correct answer: The National Incident Management System (NIMS) / Incident Command System (ICS)
NIMS/ICS provides a standardized framework for multi-agency coordination during maritime and other emergencies in the United States.
Question 7: What is the primary purpose of conducting post-incident analysis after a VTS safety event?
- To assign blame to individual operators or vessel masters
- To identify contributing factors, improve procedures, and prevent recurrence (Correct answer)
- To satisfy insurance requirements only
- To generate statistics for annual port reports
Correct answer: To identify contributing factors, improve procedures, and prevent recurrence
Post-incident analysis is a safety management tool aimed at understanding root causes and strengthening procedures to prevent future incidents.
