What You Should Know About Tugboat, Towboat and Barge Industry Safety
America’s tugboat, towboat and barge industry moves
800 million tons of cargo a year on our nation’s inland and coastal waterways. Moving this cargo safely – minimizing risks to people, property, and the environment -- is the industry’s number one goal. The Coast Guard-AWO Safety Partnership, a groundbreaking public private partnership between the U.S. Coast Guard and The American Waterways Operators, the national trade association for the tugboat, towboat and barge industry, tracks trends in towing industry safety performance. Using government data from the U.S. Coast Guard and U.S. Army Corps of Engineers, the Partnership monitors vessel casualties, oil spills, and crew fatalities, promoting continuous improvement and providing focus to Coast Guard-industry safety initiatives.
Vessel Casualties on the Decline
· Since 1996, there has been a clear downward trend in vessel casualties involving
tugboats, towboats, and barges. Vessel casualties include allisions (collisions with
fixed objects such as bridges, locks, or docks), collisions, groundings, capsizings,
breakaways, equipment failures, explosions, fires, floods, loss of electrical power,
loss of vessel control, sinkings, and structural failures. The chart below shows the
number of tugboat/towboat casualties
per one million trip miles, based on U.S. Coast
Guard and U.S. Army Corps of Engineers data.
Towboat and Tugboat Casualties
· Collisions, allisions, and groundings – the three casualty types that account for the greatest share of towing vessel casualties – are all on the decline, driving the
downward casualty trend. In 2002, the Coast Guard-AWO Safety Partnership
launched a Bridge Allision Task
Force aimed at improving public safety by
developing recommendations to prevent bridge allisions and mitigate the
consequences of bridge strikes.
Oil Spills Drop Sharply
· Spills from tank barges have dropped dramatically in the decade since enactment of
the landmark Oil Pollution Act of 1990. The volume of tank barge spills declined by
86 percent between 1994 and 2000, from 955,582 gallons in 1994 to 133,540 gallons
in 2000. Put another way, in 2000, 99.9998 percent of oil moved by tank barges was
delivered safely, as measured by volume spilled compared to volume transported.
The chart below, based on U.S. Coast Guard and U.S. Army Corps of Engineers data,
illustrates the decline in tank barge spill rates.

Gallons Spilled per 1 Million Gallons Transported
· The percentage of oil spilled from towing industry sources (tugboats, towboats, tank
barges, and freight barges) continues to drop in comparison to other marine spill
sources (such as tank ships, cargo ships, and facilities). In 2000, spills from towing
industry sources accounted for only 13 percent of marine oil spills -- down from 19.5
percent in 1999 and 30.8 percent in 1998, as the chart below demonstrates.

Crew Fatalities Show Improvement
· Towing vessel crewm
ember fatalities hit a record low in 2000, the latest year for
which U.S. Coast Guard data is available. In 2000, there were 11 fatalities, a 15
percent decrease from the previous low of 13 fatalities in 1995 and a 62 percent
decrease from the peak of 29 fatalities in 1997. While it is premature to declare the
emergence of a downward trend, the Coast Guard-AWO Safety Partnership is
studying the data to identify causal factors that will help to focus ongoing efforts to
prevent crew fatalities.
