Extreme Load Analysis

Our scientists and engineers provide clients in the upstream and downstream oil and gas industries with an array of engineering and analytical services.

Our services support the design and analysis of buildings, offshore platforms, process plant, pipelines, and other structures to withstand extreme events caused by humans, or the effects of natural hazards from earthquakes, hurricanes, floods, fires and explosions.

Earthquakes can generate extreme levels of loading in all types of buildings and structures, where deep-seated releases of tectonic strain energy causes severe shaking of the ground. The resulting demands on the built environment can be catastrophic, and engineers play a key role in minimizing the consequences of such events. Geosyntec help clients understand the physical demands on structures by characterizing ground motions, determining the dynamic properties of structures, understanding of the potential for inelastic energy absorption, and analyzing how these factors combine to generate loads and displacements.

Dangerous windstorms can strike anywhere on earth and are often compounded by heavy rainfall, storm surge, and other adverse weather events. Geosyntec can evaluate hurricane risk for a given site or region, so that the threat of a range of wind speeds and associated effects can be assessed. Geosyntec has developed tools and methods for simulating the key parameters of windstorms with results that are benchmarked to available measurements from historical events. Geosyntec can also quantify potential wind-structure interaction effects, such as dynamic excitation, vortex-induced vibration, and wind-borne debris, employing a combination of computational fluid dynamics and physics to quantify the resulting extreme loads.

Geosyntec has significant expertise in evaluating the physical demands of all types of explosions for clients, including accidental, military, and malicious explosions. Critical to dealing with the extremely energetic effects of explosions and blast loads is the understanding of blast wave properties, including overpressure and duration, and how these vary with time and distance. The interaction of these overpressures with the dynamic properties of the built environment, importantly taking account of inevitable damage, must be understood in order to understand the likely consequences.

The marine environment can present extremes of load to challenge shoreline and offshore structures. Geosyntec has particular expertise supporting clients by evaluating and quantifying the physical demands associated with the action of the sea, including wind, wave, current, ice masses, sea-borne debris, vessel impacts, extremes of temperature, and seafloor instability. Geosyntec can calculate how the severity of the loading varies with the event return period, so that the risk profile can be understood.
