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.

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.

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 LNG plant in the U.S. was planning the renovation and expansion of its existing facilities, as well as replacing and installing new pipelines for transmission and distribution. Before construction began, the client needed to be sure the potential risks were identified and successfully managed to prevent any release of LNG and damage to their existing equipment and storage tank. 
An LNG manufacturer had four nearly identical trains with three flare header systems. The client decided they wanted to use a new and more stringent criteria than previously performed under a different design criterion. The large scope and tedious nature of the data entry was a challenge since all calculations needed to be checked to determine the maximum pressure each flare pipe line would be exposed to.

The California Energy Commission was directed to assist in the development of clean alternate transportation fuels. As part of this effort, they support 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 needed to be addressed.
