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.

Our Team

Charles Lea, P.E.

Director, Minneapolis Office Lead

Mr. Lea oversees our Minneapolis office with significant experience in pressure relief and flare system design and analysis for petrochemical and chemical companies in the U.S. and overseas. He directs a number of large technical projects across multiple offices and is also responsible for all project management in our Minneapolis office. Prior to joining ioMosaic, Mr. Lea worked in the biomedical industry.

Mr. Lea specializes in pressure relief flare systems (PRFS) and effluent handling projects. He is experienced in performing complex emergency relief systems (ERS), flare, and depressurizing calculations for an array of scenarios and in the development of kinetic models from calorimetry data. Additionally, he is skilled in using chemical reactivity data and thermal analysis to complete PRFS designs for reactive systems.

Project Sampling

Analyzes pressure relief requirements using simulation software, designs relief effluent handling systems, and generates relief systems documentation.

Performed dynamic relief requirements using SuperChems™ for an alumina processing facility to determine the effects of an overpressure scenario in multiple pieces of equipment.

Evaluated risk of atmospheric dispersion for polystyrene plant. Helped the client design a flare header using existing equipment and High-Integrity Pressure-Protections Systems while providing a cost estimate to augment the existing equipment.

Performed ERS, flare and emergency depressuring calculations for multiple trains of a LNG company. Helped identify any overpressure concerns including locating areas of high acoustically induced vibration and knock-out drum analysis.

Analyzed dynamic relief requirements such as tube rupture, runaway reaction, and external fire cases where it was desired to calculated the wall temperature history.

Experience in development of kinetic models from calorimetry data.

Used chemical reactivity data and thermal analysis to complete PRFS designs for reactive systems.

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.
