Systems Theoretic Process Analysis (STPA) is a systems approach to hazard analysis. It is based on the premise that accidents happen when we lose control. They are a control problem, not a failure problem.

The GATE approach to risk ranking makes risk assessment easier, more accurate and more repeatable by incorporating LOPA insights into the risk matrix approach.

HAZOP is the most commonly applied process hazard analysis (PHA) methodology in the processing industries. It is also the most flawed!

This article discusses high-level technical considerations when refitting an existing offshore infrastructure for CCUS applications.

Energy is changing. Because of the increasing threat of the consequences of a warming planet, new sources of energy are being developed that are expected to slow this planet-wide change. Some of these are well-known, such as nuclear, wind and solar, while others require more work, such as hydrogen, 3rd generation concentrated solar and fusion.

The overall aim of carbon capture and sequestration (CCS) is to store carbon dioxide (CO2) in geological formations in order to reduce the amount in the environment and lower the risk of catastrophic climate change. The rate of CO2 emission and the amount of it in the atmosphere has been increasing steadily since the beginning of the Industrial Revolution in the early part of the 19th century.

There are several developments in the area of electrolysis which seek to reduce the cost, increase the yield, or even change the source of transportable hydrogen.

This calculator calculates the triaxial stress (VME) at a given depth.

This calculates AP collapse resistance for a specific pipe.

This calculator calculates the change in length of pipe hanging in the hole due to tension, ballooning, buoyancy and thermal effects.

The recent global over supply of crude oil and soft demand has resulted in oil companies shutting wells in to prevent destroying value and to protect their balance sheets. The time frame, until production startup becomes economic, is uncertain and therefore, it is imperative that appropriate actions are taken to maintain and manage the integrity of shut-in wells and associated delivery systems.

The time frame, until production startup becomes economic, is uncertain and therefore it is imperative that appropriate actions are taken to maintain and manage the integrity of the available Installed Production Capacity during shut-in.
