BARGE/BRIDGE ACCIDENTS STUDY REPORT RELEASED
BY U.S. COAST GUARD AND AWO
Study Conducted After Fatal Bridge Accidents
Yields Five-Point Action Plan
WASHINGTON, D.C. - The American Waterways Operators (AWO), the
national trade association for the American tugboat, towboat and
barge industry, and the U.S. Coast Guard, have jointly released
a study of barge/bridge allisions spanning ten years. Undertaken
as part of the Coast Guard-AWO Safety Partnership, the study was
conducted by the Coast Guard- AWO Bridge Allision Work Group, established
last summer in the aftermath of fatal bargebridge accidents at South
Padre Island, Texas in September 2001 and Webbers Falls, Oklahoma
in May 2002. Based upon the findings, the Work Group report identified
a fivepoint action plan to prevent bridge allisions and minimize
the consequences of those that do occur.
The Work Group examined ten years of accident data from the Coast
Guard marine casualty database on all bridge allisions involving
barges and towing vessels from January 1, 1992, to December 31,
2001. Because the Texas and Oklahoma accidents are still under investigation,
the Work Group did not attempt to draw conclusions about the causes
of those particular incidents. When those investigation results
are released, the Coast Guard and AWO will review the findings and
identify any other measures that may need to be taken to reduce
any risk to the public of allisions between bridges and towing vessels.
Key findings of the Work Group include:
- Bridge allisions involving towing vessels occur at the rate
of about six allisions per 10,000 towing vessel trips.
- The overwhelming majority of bridge allisions - 94 % -- result
in minor property damage with no personal injury or harm to
the environment. However, as the I-40 and Queen Isabella Bridge
allisions makes clear, serious accidents can occur. Since 1992,
four bridge allision cases have resulted in fatalities.
- Fully 90% of towing vessel bridge allisions are related to
human performance.
- Some 34% of the bridge allisions that occurred between 1992
and 2001 took place at bridges that have been identified by
the Coast Guard as obstructions to navigation and candidates
for alteration or removal under the authority of the Truman-Hobbs
Act.
The Work Group's five-point action plan to reduce the likelihood
of bridge allisions and limit the consequences of those that do
occur includes these recommendations:
- Implement prevention measures to improve decision making on
the part of the navigator, including: identifying vulnerable
bridges, developing safe transit procedures for vulnerable bridges,
requiring sufficient local knowledge before navigating a vulnerable
bridge, and implementing Crew Endurance Management Systems throughout
the towing industry to enhance an operator's fitness for making
good decisions.
- Accelerate the removal and alteration of bridges under the
authority and procedures of the Truman-Hobbs Act.
- Consider additional protection for bridge piers for bridges
identified as most vulnerable to allision, or to severe consequences
should an allision occur.
- Use the report as the basis for future studies by the Coast
Guard Research and Development Center to further develop potential
beneficial recommendations.
- Initiate a special investigative effort for certain bridge
allisions in which human factors issues were possible causal
factors, in order to provide future analysts with more detailed
information than is currently available.
The Work Group noted the fact that the overwhelming majority of
bridge transits take place without incident, and that most allisions
that do occur result in no damage to people, property, or the environment.
This testifies to the skill and professionalism of towing vessel
operators who do a difficult job under challenging conditions, with
very little margin for error.
AWO President Tom Allegretti observed, "Our industry is serious
about its commitment to safe operations and navigating safely through
bridges. This report helps us understand these accidents and their
causes in their broadest context. We are confident that its recommendations
will help us prevent them from happening again."
