Process Safety ::

Ponder over these incidents for a moment: February 1, 2003 a Space shuttle, Columbia, on re-entering Earth’s atmosphere at 10,000 mph disintegrated. All 7 astronauts were killed, the $4 billion spacecraft was destroyed, the Debris scattered over 2000 sq-miles of Texas, and NASA grounded shuttle fleet for 2½ years.  Earlier on July 6, 1988 a series of explosions and fires destroyed the Piper Alpha oil platform offshore North Sea, 165 platform workers and 2 emergency responders were killed. Further back in June 1, 1974, a massive vapour cloud explosion (VCE) destroyed Flixborough chemical plant, 28 employees died and 36 were injured, there were hundreds of off-site injuries, and approximately 1,800 homes and 170 businesses were damaged.


These and, painfully, many more are historical illustrations of consequences of safety incidents encountered in activities where people, the environment and assets are exposed to risks and hazards. It has therefore become pertinent for responsible organisations to assess, identify,  design-out, control and mitigate potential hazards early in any project in order to reduce these exposures to as-low-as-reasonably-practicable (ALARP).


In a highly competitive business environment, process companies cannot afford any incident where people are injured or killed, the environment is damaged, asset is lost, or reputation is hurt. There are safety standards, procedures and systems that have been developed to protect a company's employees, the environment, assets, capital investments and corporate image.


Umbarank Consult can help clients in complying with the process industry safety standards and reduce their risks. Whether your company wants to know its facility risk position or needs help with identifying and quantifying its risks or requires assistance mitigating  quantified hazards, we have a cost-effective solution for you.


Although most hazard identification studies are performed using the HAZOP, What-If, and/or Checklist methodologies, we can also provide experienced analysts to assist with more rigorous risk analyses, including:

  • PHA Facilitation
  • Risk Management Program Development
  • Qualitative Risk Assessment
  • Hazard and Operability Study (HAZOP)
  • Failure Modes and Effects Analysis (FEMA)
  • Bowtie Analysis
  • Quantitative Risk Assessment
  • Process Reliability Studies
