Williams has begun its initial damage assessment into the
deadly exploson and fire at its Geismar olefins plant in
Louisiana, saying the explosion originated in the propylene
In a news release issued Wednesday, the company said it
has key personnel at the site to begin developing
plans to make repairs, undertake a previously-planned plant maintenance turnaround and complete
a 600 million lb/year expansion of the olefins
The plant remains shut down and the expansion work that was occurring is
temporarily suspended. Neither the full extent of the damage
nor the time needed to make repairs is known.
did confirm, however, that the June 13 incident caused serious damage to
the piping, heat exchangers and reboilers in the
area just adjacent to the propylene fractionator.
Those items will likely need to be replaced.
Elsewhere, sections of the electrical cable trays in the
elevated portions of a pipe rack adjacent to the propylene
fractionator tower sustained enough damage such that
significant amounts of the electrical power cable and control
wiring in the plant will need to be replaced.
In addition, a 50-foot section of the plant pipe rack
containing portions of the plant steam system, pipeline ethane
feed vaporization systems, and fuel-gas conditioning equipment
sustained damage that will require the replacement of support
structures and significant amounts of piping.
Other equipment will be evaluated when the company has
access to the incident area.
Williams noted that it is cooperating with the
Occupational Safety and Health Administration (OSHA) and the US
Chemical Safety Board (CSB) on their investigations into the
cause of the incident.
"While the investigation and plans for repairs are underway,
the company has been and remains focused on employees, contract
workers and families personally affected by the event," the
company said in a statement.
"At this time, there are no Williams employees hospitalized;
one contract worker remains in the hospital."
