When a VTS operator issues a traffic separation scheme (TSS) restriction, which vessel is generally exempt from following the prescribed traffic lanes?
Answer: Fishing vessels engaged in fishing within the scheme
Fishing vessels engaged in fishing within a TSS are generally exempt from following the traffic lanes under COLREGS Rule 10.
A VTS operator observes two vessels on converging courses in a monitored area. The stand-on vessel fails to maintain course and speed. What action should the VTS operator take first?
Answer: Alert both vessels to the developing close-quarters situation
The VTS operator's primary role is to provide navigational safety information, so alerting both vessels to the situation is the appropriate first action.
Which document establishes the legal framework for Vessel Traffic Services in US navigable waters?
Answer: The Ports and Waterways Safety Act (PWSA)
The Ports and Waterways Safety Act (PWSA) of 1972 provides the legal authority for establishing VTS in US waters.
A vessel reports its position as '5 cables south of the main channel buoy.' How does a VTS operator convert this for plotting purposes?
Answer: 0.5 nautical miles south
One cable equals one-tenth of a nautical mile, so 5 cables equals 0.5 nautical miles.
In a VTS area, a vessel requests permission to deviate from the designated anchorage due to equipment failure. Which principle guides the VTS operator's response?
Answer: Evaluate safety implications and coordinate with relevant authorities
VTS operators must evaluate safety implications and coordinate with relevant authorities when handling requests for deviation from standard procedures.
What is the primary purpose of a vessel traffic management plan (VTMP) in a VTS area?
Answer: To establish a framework for safe, efficient, and environmentally sound traffic flow
A VTMP establishes the framework for managing vessel movements to ensure safety, efficiency, and environmental protection within the VTS area.
A VTS operator detects a vessel on radar that has not made a required position report. After one attempt to contact the vessel by VHF, what is the next recommended action?
Answer: Attempt contact on an alternative channel or via another vessel
Standard VTS protocol calls for attempting contact on alternative channels or through relay before escalating to other agencies.
