The committee investigated a number of existing applications and bene fited from the experience of three of its members in the development and use of such systems in the lower Mississippi River, Tampa Bay, and San Francisco. In examining current projects, the minutiae of display technol ogy were avoided, and the focus was on broader lessons that might apply.

In the lower Mississippi, for example, local mariners now recognize AIS technology as a tool that vastly improves the quality of navigational information available to them, simplifying the retrieval of that information in the process. One of the most frequently cited issues is information overload.

Two evaluations of the St. Lawrence Seaway AIS project are currently scheduled -- one a comparison of AIS use and electronic chart dis play and information system (ECDIS)

AIS equipment is installed on some vessels that regularly transit German coastal waters, however, and German shore-based vessel traffic con trol centers have experience with shore displays of AIS signals. Even though this work does not include shipboard displays, such shore-side experience may be useful to take into account.

. British Columbia Operational Tests The Canadian Coast Guard and three Princess Cruises' ships participated in a non-1371 standard AIS evaluation project that was partially funded by the Western Marine Community's Pacific Coast Marine Review Panel in the summers of 1999 and 2000.

Although there was no consensus as to how to label AIS targets in these trials, all bridge teams agreed that the labels should be short to minimize on-screen clutter. One of the bridge teams preferred to use some of the ECDIS screen to show an AIS target's rate of turn, if available, followed by P or S (port or starboard)

Replies referenced the original message. Standard messages were used in this test of intership e-mail, and replies were not customizable so as to avoid "chat." Bridge teams in the summer 1999 British Columbia project believed that intership e-mail might reduce the need for intership and ship-to-VTS report ing VHF communications.

The label should default to the first 10 characters of the full name but should be editable. Collision avoidance forms, target information forms, own ship collision avoidance forms, and own ship information forms, with required infor mation types, were defined and recommended by test participants.

Coast Guard (USCG) , in cooperation with local mariner organiza tions and pilots, sponsored a project on the lower Mississippi River to intro duce AIS shipboard transponder systems into the maritime operations in the region beginning in 1998 and continuing through 2002.

One is that of information overload, because with so much data readily available, mariners must learn how to rec ognize priority information without being distracted by peripheral "chatter." They must know how to effectively use the data provided to enhance bridge resource management. They must know who should monitor what equip ment and what information to relay to whom.

From page 70... ...
Regardless of the technology used, text messaging will require some kind of policing, per haps with locally defined, allowable text messages. The mariners involved in the lower Mississippi River AIS tests have con cluded that several issues need to be addressed before the full value of the technology can be realized.

Tampa Bay Vessel Traffic Information System with Shipboard/Carry-Aboard Displays The transponder-based pilot carry-aboard units incorporated into the Tampa Bay Vessel Traffic Information System (VTIS) provide another example of a display of AIS-type data tailored to the user's needs that can be used to inform the development of future standards and guidelines.

It has open water approaches, a relatively large bay, and many miles of narrow channels and rivers that require preci sion navigation and present diverse vessel traffic situations. The project began by establishing a Joint Planning Partnership with rep resentatives of ferryboat operators, tug companies, barge operators, con tainer and tanker vessel operators, and the San Francisco Bar Pilots to oversee administration.
|
From page 73... ...
Eight San Francisco Bar Pilots were designated to conduct the evaluations and submit their findings and recommendations. Participants in the project concluded that the technology, although in its infancy, has the potential to develop into an effective navigational tool.
|
From page 74... ...
Selected members of the San Francisco Bar Pilots tested four portable pilot units, each manufactured by a different company. The evaluators were asked to appraise the units and AIS in the same interest areas as the AIS group (i.e., vessel traffic management, vessel navigation safety, reduced visibility/ night navigation, bridge resource management, and overall vessel operations)

through a "universal plug." The units should include a wireless Internet access to receive local mete orological, hydrological, and other notices of interest to the mariner. Nautical software developers should work with local mariners to incor porate features to meet their needs.
|
From page 76... ...
Their initial skepticism diminished as they became accus tomed to the technology and realized the benefits of accurate, real-time navigational data from AIS displays. In the lower Mississippi River tests of pilot carry-aboard AIS units, skepticism about the technology among local mariners diminished sharply after they became accustomed to the system and recognized the benefits that it offered.
