Safety in the LNG Value Chain

Dec 12, 2012
Georges Melhem, Henry Ozog

In this webinar, presenters describe and examine potential LNG (liquefied natural gas) hazards and risk-reduction methods for the LNG value chain ― production and consumption.

Designing LNG Vapor Dispersion Exclusion Zones to Protect the Public

Apr 5, 2012
Jerry Havens
The LNG industry, if not the entire energy industry, may be at a crossroad. Expectation of large shale gas supplies in the United States, with a backdrop of international economies in precarious states, makes more uncertain the promise of major investments in LNG import facilities. Already, a...

Design Challenges in Tankage Modernization

Apr 4, 2012
James Kong
In order to comply with regulation requirements, a refinery needs to perform major revamps to produce different grades of Diesel, namely ULSD, Off-road Grade and Regular Diesel. The existing tankage allocation needs to be changed to accommodate the hydrotreater feed components and the new products...

More LOPA Misapplied: Common Errors and How to Avoid Them

Apr 4, 2012
Karen Study
Layer of Protection Analysis (LOPA) continues to be more and more widely utilized in the Petrochemical and other industries. LOPA is a “simplified” tool, which is true relative to tools such as Quantitative Risk Assessment and Fault Tree Analysis. However, simplified does not mean simple on an...

Working Under Pressure (How do you manage pressure hazards?)

Apr 4, 2012
Dr. Angela E. Summers
Industry is increasingly moving towards utilizing High Integrity Protective Systems (HIPS) to reduce flare loading and prevent the environmental impact of pressure venting. HIPS are becoming the option of choice to help alleviate the need to replace major portions of the flare system in existing...

Societal Risk Criteria and Pipelines

Apr 4, 2012
Joan M. Schork
The discussion of societal risk criteria for the process industry began in the 1970's, led primarily by the Dutch and British governments. Most of the discussion, however, has centered on fixed facilities. The literature on the societal risk of hazardous goods transportation, particularly by...

Two Incompetent Workers; Too Close for Comfort ñ Part 1

Apr 4, 2012
Mike Broadribb
Learning from experience is one of the four pillars of Risk-Based Process Safety. Incidents that occur at one facility often provide opportunities to strengthen management systems at other facilities. Sharing the technical lessons learned from incidents is morally right and vital to improving...

Explosions in Transformer and Circuit-Breaker Tanks Due to Arcing Events

Apr 4, 2012
Timothy L. Morse
Industrial transformers and circuit breakers operate with large voltage differences between current-carrying internal components and the grounded tank walls. A breakdown in the dielectric strength of the insulating oil in the tank due to contamination or other causes can lead to the formation of an...

Apr 4, 2012
Russell A. Ogle
A truck driver loading a tanker was fatally injured in a flash fire. The accident occurred at the loading rack of a petroleum refinery. The truck driver was on top of the tank trailer loading a liquid petroleum byproduct material similar to asphalt through an open hatch on the trailer. The material...
