VTS Vessel Traffic Management & Navigation 5

Question 1

When two vessels are converging and both are in a VTS area, the VTS operator's traffic information call does NOT relieve which party of responsibility?

Accepted Answer

The vessel masters from their obligation to comply with COLREGS and navigate safely

Answer

VTS information services never transfer responsibility for safe navigation from the vessel master; COLREGS compliance remains entirely the master's duty.

Question 2

What is the purpose of a 'deep-water route' designated within or adjacent to a VTS area?

Accepted Answer

To provide a route with greater underkeel clearance for large, deep-draft vessels

Answer

Deep-water routes are specifically designated to give deep-draft vessels sufficient underkeel clearance, reducing grounding risk in areas where the main channel has marginal depths.

Question 3

A VTS operator receives conflicting position reports from two vessels in close proximity. What is the most reliable method to resolve the discrepancy?

Accepted Answer

Cross-reference radar, AIS, and if available, visual observation or CCTV to determine actual positions

Answer

Cross-referencing multiple independent data sources — radar, AIS, and visual — provides the most reliable position verification when vessel reports conflict.

Question 4

What does 'VTIS' stand for and how does it differ from a full VTS?

Accepted Answer

Vessel Traffic Information System; it provides information only without traffic organization authority

Answer

VTIS (Vessel Traffic Information System) provides navigational and traffic information to mariners but lacks the authority to organize or direct traffic as a full VTS does.

Question 5

A vessel has been involved in a minor collision within the VTS area and both vessels are still underway. What is the VTS operator's documentation obligation?

Accepted Answer

The operator must record the incident details, communications, vessel identities, time, location, and notify the Coast Guard Sector

Answer

All incidents within a VTS area must be logged with full details and reported to the Coast Guard Sector regardless of severity, as they may trigger investigation or response.
