CFD Helps Design Marine Vessels to Withstand Extreme Waves

Most of Brazil’s offshore resources are in deep waters so Petrobras has fostered substantial expertise to develop these fields. One area of importance is the design of marine vessels to withstand the extreme waves. While the discovery of 50 billion barrels of oil in recent decades has been a boon to Brazil’s economic outlook, the location of the oil has produced challenging engineering problems. Lying hundreds of kilometers offshore under up to 3,000 meters of seawater, 2,000 meters of rock and 2,000 meters of salt, the oil reserves are some of the most difficult to access on Earth. Engineers are systematically using best design practices and computational fluid dynamics (CFD) to increase the safety of marine structures and vessels used to drill and produce oil from Santos Basin fields.

The Industrial IoT Runs Roots in the Oil & Gas Industry

digital twin oil and gas industryIndustrial IoT and digitization will loom large as the industry professionals gather at this year’s Offshore Technology Conference (OTC) in Houston, Texas, May 1-4. Over the past few years the industrial IoT has grown beyond information technology concerns (gathering data, data processing and security, etc.) and now includes predictive maintenance of assets, prognostics health management (PHM), reducing cost and nonproductive time, eliminating breakdown and failure.

One of the first steps in realizing the benefits of the IoT for the energy industry is to create intelligent machines/digital products. As evident from consumer product devices, for example smart watches, soon if not already, oil and gas equipment will also need to perform more than just a mechanical function and must become smart or intelligent.

Sustainability in the Chemical and Process Industries

pillars of sustainabilitySustainable engineering along with process safety is one of the technical tracks in this year’s upcoming Spring meeting of the American Society of Chemical Engineers – March 26-30 San Antonio, TX. The forum covers a range of process design topics, presentations and discussions around environmental initiatives for air, water and soil protection. So, what is sustainability and what are chemical engineers doing about it? Continue reading

Powering Global Prosperity: New Energy for Pressing Industry Challenges

Global prosperity requires reliable energy at a reasonable cost. To meet this demand, the industry is changing the way it produces energy and power, whether it comes from hydrocarbon, nuclear or renewable means. Supplying it requires sustainable development, environmental stewardship, compliance with regulations and cost management. Independent of prices, the industry’s most pressing challenge is cost per unit of energy. Recent layoffs and out-of-the ordinary cuts to capital and operating costs are driving the oil and gas industry to produce energy more efficiently, more safely, and with a smaller carbon footprint. Debate over subsidies, reliability and viability have resulted in accelerated development/deployment and widespread innovation in renewable energy, which includes solar, wind and hydropower, fuel cells, wave and tidal, energy storage, the next generation of fission nuclear reactors and advancements in fusion energy.

Is Your Industrial Equipment Ready for the Industrial Internet of Things (IIoT)?

industrial internet of things iiotThe Industrial Internet of Things (IIoT) is changing the way the world designs, connects and optimizes machines. The advent of the IIoT brings together the things of the industrial sector (countless pieces of industrial equipment, machines, production facilities, plants) with a network (high speed routers, switches and gateways) and the cloud (access to cutting-edge local or remote computing on private or public computing clusters), which hosts the software and analytic for making decisions based on data from the things. In effect, the IIoT is connecting IT, product design and operational technologies. Industrial equipment must become digital or “smart machines.”  Continue reading

COP21 – A Call for Engineers and Scientists to Innovate

As the 2015 United Nations Climate Change Conference — COP21 — took place in Paris, I watched as business and world leaders met with the goal to reach a binding agreement on climate policy among all nations. One of the main objectives is to set a path to limit global warming below 2 degrees Celsius by 2100 by reducing man-made emissions of CO2 and other greenhouse gases (GHGs). Continue reading

Predicting Equipment Fatigue Caused by Flow-Induced Vibration

Tacoma Narrows BridgeThe energy of a human voice at certain pitch and volume can shatter a wine glass due to vibrations caused by sound waves. Motion of fluids can also create structural vibration, sometimes with disastrous consequences: In 1940, the Tacoma Narrows Bridge in Washington state collapsed when high winds caused the structure to oscillate with increasing amplitude from end to end, until sections of the bridge fell into the river. The bridge structure was responding to the transient forces caused at certain flow frequencies as the wind blew past the bridge. At a critical vibration frequency corresponding to the natural (or harmonic) frequency of the structure, mechanical resonance occurs, and the objects fail — glass shatters, the bridge collapses.

A Proven Approach to Reduce Oil and Gas Industry Costs

OTC2015Oil and gas industry professionals will be gathering at the Offshore Technology Conference (OTC2015) in Houston, May 4-7. This year’s OTC event is taking place at a time when there are understandable concerns about jobs, costs and investments due to continued uncertainties in petrochemical prices, global demand and realigning of capital investments. ANSYS is going to the OTC conference because we believe that the energy industry is resilient. We also believe that ANSYS has solutions to help the industry cut costs through improvements in engineering best practices and use complete virtual prototyping of its system with the insight needed to prioritize and optimize the industry’s investments and adoption of advanced technologies.

Could Innovation and Engineering Cause Dropping Oil Prices?

The recent drop in oil prices naturally has produced economic winners and losers, and price speculators and pundits are lining up conventional producers against those behind American-drilled Shale oil. Yet, questions remain about how the world is over-supplied with oil only a few years after we supposedly passed peek oil and survived oil prices topping $140 per barrel. Discounting the anticipated demand softness due to economic activities in Europe and Asia, technology is playing a strong role in finding, producing and using energy across the full range of industrial activities.
