Take 10 #18: Vessel traffic services

01 Jun 2018 The Navigator

This issue of The Navigator explores multiple aspects of VTS communications and how to promote best practice.

1 End goal

The goal of VTS is to improve safety, security, environmental protection and the commercial efficiency of the port.


2 Relationship matters

The professional relationship with VTS operators is as important as those among the crew onboard.


3 Clear and concise

Clear communication depends on proper use of both technology and language. English may not be a first language, so be as clear and concise as possible, using SMCP where possible.


4 Know your VTS types

There are three types of VTS: INS, TOS and NAV. The sailing directions for the region will tell you which kind of VTS is operating in the area.


5 Information station

INS is an information service only. It may include information on other vessels, visibility or weather, AtoNs, etc.


6 Spatial awareness

TOS is a Traffic Organisation System. It manages space in the waterway, which may include allocating arrival or departure times and assigning anchor spaces.


7 A helping hand

NAS is a Navigation Assistance Service. It can provide results-oriented advice and information to assist in onboard decision making.


8 The eyes have it

VTS has reliable and accurate coverage of the traffic situation in the area – but don’t forget to use your own eyes as well!


9 Keep in touch

Vessels operating in a VTS area should acknowledge information and respond promptly to inquiries and warnings.


10 A new career path?

There are international standards for VTS Operator training. Being a VTS Operator could be a career option for mariners.
