Example Investigations Performed by ABS Consulting


Industry Type

Brief Description

Explosion leading to three fatalities

Offshore Drilling

While performing welding activities, an explosion occurred that resulted in propelling three tanks off the platform and killing three workers. Hot work permit issues and contractor oversight were major issues identified. ABS Consulting performed evidence collection, root cause analysis, fire and explosion modeling, coordinated laboratory analyses, and interfaced with BSEE and legal counsel during the investigation.

Stack Failure

Chemical Processing

A 200' steel stack fell onto the bag house. The stack had rapidly corroded over a period of two years because of problems with the materials of construction and operational problems that lead to excessive chlorides in the stack plume. The investigation involved causal analysis and metallurgical analysis issues.

Metal Fabrication and Process Failures


An analysis was conducted to identify potential causes of chronic manufacturing problems with a complex stamped and welded component.

Near-miss Electrocution

Electric Utility

During construction operations, a contract worker climbed onto an energized high-voltage transformer. An HSE professional noticed the worker was in a prohibited area before the contractor was electrocuted. ABS Consulting assisted the utility RCA team in performing their analyses.

Crane Runs Off Rails and Cab Falls to Floor


A bridge crane ran off the crane rails and the cab crashed to the floor. The crane operator was killed. Some mechanical issues, human errors, and human factors issues contributed to the incident. ABS Consulting led the root cause analysis team.
