The
U.S. Coast Guard will attest to the fact that the Mississippi
River is unsurpassed in traffic density. Swift currents and
shifting sandbars increase the unpredictability and difficulty
of navigation on the river. Yet, over the last decade, with
159,646 vessel movements, 12.5 million miles transited and
5.7 billion deadweight tons moved, the Crescent Pilots have
a safety record of 99.9%. Likewise, the Bar Pilots have had
135,000 ship movements between 1991 and 2001, while maintaining
a safety record of 99.9%. In the Lake Charles Pilots
77 years, there has never been an incident where a pilot was
found negligent. The NOBRA Pilots have a safety rating
of 99.9%.
The Louisiana River Pilots help safely transport valuable
freight to and from our ports.
Cargo ships typically carry:
- Crude
oil
- Gasoline
- Liquefied
natural gas
- Chemicals
(in many varieties)
- Aggregate
- Bulk
agriculture and bulk pet-coke
These
cargo ships range from 400 feet to 968 feet in length and
can easily consume a small channel. If not navigated safely,
the ship can be dangerous to our waterways, economy, and way
of life. This is why we have experienced pilots that are continually
trained for ultimate safety on our waterways.

When a pilot boards a ship, he or
she must assess:
- Weather
conditions
- Traffic
density
- Fitness
of crew members
- Competence
of officers
- Activities
on the ship
- Status
of the instrumentation
- Ship
handling characteristics
- Configuration
of the bridge
- Language
barriers
- Develop
a passage plan
ALL THESE
THINGS IN A MATTER OF MINUTES!
Why It Works
The state commission system of oversight provides several
benefits which are unattainable via alternate systems including:
- Local
Knowledge Each Commissioner has intimate knowledge
of the river, the facilities, and in most instances, the
vessels which transit the river.
- Continued
Involvement Unlike the U.S. Coast Guard, which utilizes
a rotation system, the Board of Commissioners serves at
the pleasure of the Governor, generally four years or longer.
- Resources
Funding for the needs of the Commission, or time
dedicated to an investigation, do not deter the Commission
from completion of their duties. The Commissions primary
objective is safety.

After
Sept. 11, there was a need to improve existing port security
measures and increase port security awareness. VTS is currently
up and running and the equipment is being used to guard ports
and facilities along the Lower Mississippi River. Coast Guard
Reservists were brought in to man the facility and provide
Maritime Domain Awareness. By tracking vessels categorized
as high interest or those carrying hazardous cargo, they are
able to supply an accurate database for law enforcement and
intelligence agencies.
Both Crescent River and NOBRA pilots take shifts at the Vessel
Traffic Center, advising the Coast Guard on traffic management,
HIV vessels and emergency situations.
The pilots have been well trained in operating the system.
VTS courses and the day-to-day valuable hands-on-experience
have allowed pilots to achieve a very high standard. This
will be valuable in the facilitation on commerce and port
security on the Mississippi River. Pilots are a key part of
VTS. Without them, the moving dots on the computer screen
would simply pinpoint locations. The pilots, with their extensive
knowledge of the river, are able to take that location and
calculate an entire list of guidelines. Using factors such
as direction and speed of the current, direction and speed
of the wind and other environmental factors, determine the
vessels speed and direction and its cpa
closest point of approach, tcpa time of closest
point of approach, and gcpa geographic closest
point of approach, to other vessels underway or vessels moored
to various port facilities.
Presently, ships are tracked on the Lower Mississippi using
radars, low light CCTV, and contacts from the vessels
bridge, but this method does not provide a comprehensive real-time
picture. This traditional method of monitoring vessel traffic,
known as a Vessel Movement Reporting System (VMRS), relies
on ships to report their locations every 20 miles.
The plan is to require every vessel entering the Mississippi
River, in fact all ports world wide with an onboard transponder,
(AIS). Automatic Identification System (AIS), will give continuous,
real-time updates along with critical static and dynamic vessel
information, i.e. type of ship, ships identification,
ships location, cargo, draft, speed, course, pilot on
board. AIS was slated to be fully functional by 2008, yet
after the urgency of Sept 11, Senator Breauxs push for
action cut the time frame in half to 2004. This system is
required under International law to be aboard all tankers
by July 1, 2003 and is required on all other sea going vessels
by July 1, 2004. This same system will be required on most
domestic vessels under U.S. law by July 1, 2004.
AIS will pinpoint every movement of the vessel, transmitting
important information back to the pilots. It will function
as the eyes for a pilot when the river is covered in fog or
a hidden ship is approaching from below a point or bend in
the river AIS will provide pilots with the ability to keep
the decision-making on the vessel. The land-based VTS operators
will use AIS to inform mariners (pilots) of potential hazards
ahead and may recommend or issue directions for avoiding them.
The New Orleans AIS based VTS system will be fully operational
by the end of 2004. All major U.S. ports want the same state-of-the-art
VTS system being put in place here, but the New Orleans/Baton
Rouge port area, being the largest in the world, is number
one on the VTS port list. Other U.S. ports will be retrofitted
soon after New Orleans is completed.
