SUBJECT: Test of AIS Transponders in British Columbia/Alaska Summer 2000
DATE: July 20, 2000
Return to home page
The test installation of AIS transponders is progressing well and is expected to be completed in early August.

I should like to request your assistance in this evaluation of AIS as an aid to safe navigation and collision avoidance. The reason for asking you to do so, is that international standards for integration of AIS in bridge displays are currently being developed by IMO. Holland America Line and Princess Cruises intend to participate in this standard setting process.

Test Objectives
The main objective of the test is to verify that AIS allows a ship's bridge team to become aware of nearby vessel traffic which cannot either be seen visually, or acquired by ARPA due to topographical features. The second objective is to determine to best way to integrate AIS into the electronic chart or radar display.

Caution
The AIS transponders have not yet received type approval for connection to the ships principle ARPA or ECDIS, which are required to be carried by SOLAS. You should therefore ensure that the display of AIS information does not interfere with the normal operation of the principle ARPA or ECDIS display of your integrated bridge

Sponsors
This test is an initiative of the Pacific Marine Review Panel (PACMAR). The test is sponsored by Transport Canada, the Canadian Coast Guard, Holland America-Line Westours, Inc., Princess Cruises, NWCA and Tideland Signal Corporation.

Briefing
Briefings for the test will be held on SEA PRINCESS on Saturday August 12, on REGAL PRINCESS on Sunday August 13 and on VOLENDAM on Monday August 14.

Test Period
The main test will start after the briefing and end upon de-briefing (see below). Until mid-day on Saturday August 26 the base station on Discovery Mountain (opposite Chatham Point) will be passive. After that it will re-broadcast the AIS transmissions it receives. This should significantly extend the range of AIS in the Seymour Narrows area.

Log Files
To allow a Cadet of the Maritime College in Vancouver (BCIT) to analyse AIS and ARPA observations, starting August 1, please periodically save the ChartPilot log file and NaviSailor Track Files on diskettes and send them to PACMAR, c/o Rose Bray, Chamber of Shipping of British Columbia, 100-1111 West Hastings Street, Vancouver, BC, V6E 2J3, Canada. Detailed instructions on how to save log and track files are attached.

Debriefing
A delegation representing the test sponsors will visit your vessels towards the end of the season to gain direct user feedback by discussing AIS with you and your officers. These meetings are scheduled for Saturday September 9 on SEA PRINCESS, Sunday September 10 on REGAL PRINCESS and Monday September 11 on VOLENDAM.

To prepare for the debriefing, I should be grateful if your Bridge Team could begin to develop an evaluation of AIS, including but not limited to:
 

  1. Keeping a manual log of AIS targets seen on the STN Atlas MultiPilot II or Transas NaviSailor during the main test period (See attached Form and a listing of Inter-Ship AIS Events).
  2. Listing pro's and con's of displaying SOLAS ship AIS targets on the electronic chart or radar, with recommendations as appropriate.
  3. Listing pro's and con's of displaying not only SOLAS, but also non-SOLAS vessels equipped with AIS, even boats smaller than 20 m LoA.
  4. Listing the range (or TCPA) at which SOLAS targets would be useful, the range at which non-SOLAS targets greater than 20 m would be useful and the range at which non-SOLAS targets smaller than 20 m LoA would be useful
  5. Ranking of AIS features (SeeAppendix Chapter I)
  6. Ranking of AIS Display Options (See Appendix Chapter II)
  7. Describing Involvement of BC & Alaska Pilots - their knowledge of and their reaction to AIS.
  8. Describing the AIS effect on VHF traffic with Comox MCTS when in range of Discovery Mountain Base station.
  9. Listing Technical aspects of AIS - i.e. ease of transponder maintenance & operation.
  10. General comments.
Thank you in advance for your assistance.
