VTS Vessel Traffic Management & Navigation 4

Question 1

What is the correct VHF channel for vessel traffic in most U.S. VTS areas for primary working communications?

Accepted Answer

The designated VTS working channel specified in the Notice to Mariners for that area

Answer

Each U.S. VTS designates a specific working channel published in Local Notices to Mariners; Channel 16 remains the distress and calling channel, not primary VTS working channel.

Question 2

A LNG carrier is approaching a VTS zone. Compared to a standard cargo vessel, what additional considerations apply?

Accepted Answer

LNG carriers require safety zones, escort requirements, and coordination with local emergency response agencies

Answer

LNG carriers typically require mandatory escort vessels, exclusion zones, advance coordination with fire and hazmat response, and often special routing plans within VTS areas.

Question 3

What is the purpose of a 'vessel traffic center' (VTC) maintaining a traffic log?

Accepted Answer

To provide a chronological record of communications, vessel movements, and incidents for accountability and post-incident analysis

Answer

The traffic log serves as an official record that enables incident reconstruction, performance review, legal accountability, and training improvement.

Question 4

In reduced visibility conditions, which regulation governs how a vessel must navigate within a VTS zone?

Accepted Answer

COLREGS Rule 19 governs vessel conduct in restricted visibility, supplemented by VTS advisories

Answer

COLREGS Rule 19 requires safe speed, readiness to stop, use of radar, and caution in restricted visibility; VTS supplements this with traffic information but does not supersede the COLREGS.

Question 5

What does the term 'traffic separation scheme' (TSS) intend when it designates an 'inshore traffic zone'?

Accepted Answer

A zone between the TSS and the coast where local small craft and coastal traffic may navigate without using the main traffic lanes

Answer

Inshore traffic zones allow smaller vessels and coastal traffic to operate without entering the main TSS lanes, reducing conflicts between ocean-going and local traffic.
