LNG Risk Management

Managing the risks of onshore and offshore LNG facilities via a thorough understanding of the design and key issues associated with liquefied natural gas.

Our multifaceted approach takes into consideration the needs of regulators, engineering contractors and most importantly, you. LNG terminals, send-out facilities and associated pipelines, and power plants around the world rely on our extensive experience to complete QRAs, HAZOP and hazard identification studies, safety integrity level (SIL) reviews, and consequence analysis modeling.

Neil Prophet

Senior Vice President and Partner

Mr. Prophet brings over 20 years of experience in the field of process safety to his role as a leader of the Relief Systems group. Mr. Prophet manages our Houston office and oversees major Pressure Relief and Flare Systems Design and Quantitative Risk Assessment (QRA) studies. 

Mr. Prophet's roles in the process safety field have included consulting, project management, technical support, technical sales, training course development and presentation, and operations management. He has assisted operating companies and consultancies in the chemical, pharmaceutical and petrochemical industries with hundreds of projects in all areas of process safety.

Mr. Prophet has authored/co-authored many industry white papers on aspects of process safety in addition to presenting over 50 training courses and seminars covering consequence analysis and risk analysis to both operating and consulting companies.

Project Sampling

Experienced with all aspects related to pressure relief and flare system design as well as the relevant codes and practices. His familiarity ranges from relief system data gathering, isometric sketching, pressure relief and flare system calculations and report generation, and development of mitigation options. He has also analyzed individual relief valves, pressure vents, flare systems and vent header systems.

Performed quantitative risk assessment studies of three natural gas transfer facilities located in Brazil and one natural gas transfer facility in Canada.

Managed a project team which performed major QRA and building vulnerability studies of two entire oil refineries in the Middle East.

He has participated in numerous hazard identification studies for a variety of scenarios including liquefied natural gas (LNG) terminals, oil terminals, tank farm and wharf, laboratory relocation, numerous overpressure scenario reviews, etc.

During his time at Det Norske Veritas, he acted as department internal auditor and later as an office quality manager, while ensuring ISO 9000 compliance.

Project manager and lead auditor of a major relief systems audit for a large U.S. refinery, reviewing all aspects of the relief and flare systems design basis.

Conducted a QRA for an energy company in the Middle East to determine the feasibility of an LNG import terminal, including individual risk contours for the three proposed locations and development of societal risk FN curves.

Process Safety Management Quality Audits

Companies have implemented their process safety management programs to comply with OSHA and EPA requirements, but they continue to have accidents. Process safety management programs can meet the letter of the law, but may not be effective in preventing accidents. Traditional audit programs look at documentation and procedures, but do little to evaluate the program quality or effectiveness.

View Case Study

An international consumer products manufacturer suffered a significant business interruption due to failure of a critical support facility. This incident raised the question of whether there were other critical support facilities that could cause a similar interruption in production or a significant safety or environmental impact.


The California Energy Commission had been directed to assist in the development of clean alternate transportation fuels. As part of this effort they are supporting the commercialization of fuel cell vehicles operating on hydrogen fuel. In order to be used extensively in the transportation sector, the safety of hydrogen production, storage, and supply needs to be addressed.

A multinational energy company wanted to complete an evaluation of a PRV system in order to comply with the PSM standard OSHA 29 CFR 1910.119 which requires that employers compile information pertaining to the equipment in the process, including relief system design and design basis.

Quantify Non-Equilibrium Flow and Rapid Phase Transitions (RPT)

Although non-equilibrium flow and rapid phase transitions (RPT) are well researched, the literature published so far does not explicitly quantify the RPT phenomenon or provide reliable methods for the calculation of non-equilibrium flow for mixtures. Download this paper for a clear understanding of how non-equilibrium flow and rapid phase transitions develop and how they should be quantified for pure components and mixtures alike.
