VTS Safety Procedures 2 — Questions and Answers
Question 1: When a vessel reports a medical emergency aboard, what is the VTS operator's FIRST priority action?
- Notify the vessel's owner or agent
- Obtain the vessel's position and nature of the emergency (Correct answer)
- Contact the nearest hospital for medical advice
- Log the incident in the traffic record
Correct answer: Obtain the vessel's position and nature of the emergency
Obtaining the vessel's position and the nature of the emergency is the first step to coordinate an appropriate response.
Question 2: Under what circumstance may a VTS operator issue a navigational warning to ALL vessels in the service area?
- When a single vessel requests updated weather
- When a hazard exists that could affect the safety of all traffic in the area (Correct answer)
- When traffic density exceeds normal levels
- When a vessel fails to respond to a routine traffic call
Correct answer: When a hazard exists that could affect the safety of all traffic in the area
Navigational warnings are broadcast to all vessels when a hazard poses a risk to the general safety of navigation in the area.
Question 3: A vessel reports loss of steering in a narrow channel. Which action should the VTS operator take IMMEDIATELY?
- Advise the vessel to anchor and wait for a tug
- Alert all vessels in the vicinity and restrict traffic as needed (Correct answer)
- Transfer the call to the port captain only
- Record the event and monitor without action
Correct answer: Alert all vessels in the vicinity and restrict traffic as needed
Alerting nearby traffic and restricting movements prevents collision while the disabled vessel manages the emergency.
Question 4: What does the term 'security call' refer to in VHF radio procedure?
- A distress signal requiring immediate assistance
- A safety announcement of a navigational hazard or meteorological warning (Correct answer)
- A request for vessel identification
- An encrypted channel reserved for port authority use
Correct answer: A safety announcement of a navigational hazard or meteorological warning
SÉCURITÉ is the ITU safety signal used to announce navigational hazards or important meteorological warnings.
Question 5: A VTS operator receives an incomplete MAYDAY relay from a passing vessel. The distressed vessel's position is unknown. What is the best immediate step?
- Broadcast the MAYDAY relay to all stations with the partial information available (Correct answer)
- Wait for a clearer signal before taking action
- Contact the Coast Guard only after confirming the position
- Ask the relaying vessel to repeat on a working channel
Correct answer: Broadcast the MAYDAY relay to all stations with the partial information available
Broadcasting a MAYDAY relay immediately with available information activates the widest search and rescue response.
Question 6: Which federal agency holds primary responsibility for search and rescue coordination in US coastal and inland waters?
- NOAA
- U.S. Navy
- U.S. Coast Guard (Correct answer)
- Army Corps of Engineers
Correct answer: U.S. Coast Guard
The U.S. Coast Guard is the lead federal agency for maritime search and rescue operations in US waters.
Question 7: What is the purpose of a Vessel Traffic Service 'safety fairway' designation?
- To reserve lanes exclusively for commercial deep-draft vessels
- To define areas where anchoring is prohibited to keep a corridor clear for SAR and emergency vessels (Correct answer)
- To mark high-speed ferry routes on nautical charts
- To indicate areas with mandatory speed limits
Correct answer: To define areas where anchoring is prohibited to keep a corridor clear for SAR and emergency vessels
Safety fairways are kept clear of anchoring and obstructions to provide unimpeded access for search and rescue and emergency response.
