3. Various vocabulary terms are defined to familiarize workers with important safety concepts. Hazards like hydrogen sulfide gas, rotating equipment, overhead loads, and improper protective equipment use are some of the risks addressed.
The Rig Safety Awareness course features ten e-learning modules, designed for new technical and petroleum engineers going offshore for the first time. The modules will require between 30 to 40 minutes study each.
Each module will also include assessment questions that relate to module’s content. Each e-learning module will be supported by four 2D ‘Walkthrough Events’ where the user is stepped through a series of safety failures that leed to an incident occurrence.
A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation.
One the most important problem in the chemical, oil&gas or nuclear Industry is the Risk Assessment evaluation. In the theoretical studies, the part of risk analysis is sometimes not considered because the case of study is not real or it hasn't been still industrialized. In the real industry there are different processes for industrializing a product. The HAZOP technique is one example of Risk assessment tecniques.

Introduction to PSM Online Interactive TrainingJohn Kingsley
Process Safety Management (PSM ) refers to a set of interrelated approaches to manage hazards associated with the process industries and is intended to reduce the frequency and severity of incidents resulting from releases of chemicals and other energy sources. These standards are composed of organizational and operational procedures, design guidance, audit programs, and a host of other methods.
A comprehensive PSM program to identify, assess and control facility hazards, including fires, explosions and the release of highly hazardous chemicals is crucial to any industrial organization’s safety plan. With iFluids online PSM training, learners will gain important information about the elements most frequently cited by OSHA, as well as topics like emergency planning and response, mechanical integrity and management of change at a fundamental level.

Sil assessment Risk Graph and LOPA Training iFluidsJohn Kingsley
LOPA is the newest methodology for hazard evaluation and risk assessment. On a sliding scale of sophistication and rigor, LOPA lies between the qualitative end of the scale (characterized by methods such as hazard and operability, or HAZOP, analysis and what-if analysis) and the quantitative end (characterized by methods using fault trees and event trees). LOPA helps the analyst make consistent decisions on the adequacy of existing or proposed layers of protection against an accident scenario. The technique is ideally suited for companies striving to meet specific risk targets or to lower risk as low as reasonably practicable (ALARP).

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

IT’S THE LAW !
In the State of Texas, all persons working in the oil field where
H2S concentrations are known MUST complete a H2S
certification course annually.
The objective is to educate employees about the physical &
chemical properties, toxicity, concentration levels, personal
protective equipment use, detection measures, rescue and first
aid.
The best way way to reduce the chance of employee exposure to
H2S is to provided the best possible training, provide appropriate
personal protective equipment, and ensure employs follow the
correct work procedures, rules and requirements.

H2S or Toxic Gas ExposureH2S or Toxic Gas Exposure
Hydrogen Sulfide – characterized by an odor
of rotten eggs. A very small concentration
can be fatal. When encountered, employees must wear
approved type masks when their work requires them to be
exposed to the gas,in any way.
27. 27
H2S or Toxic Gas ExposureH2S or Toxic Gas Exposure
Hydrogen Sulfide is highly toxic, colorless, and heavier
than air. It has the odor of rotten eggs, initially.
Most frequently encountered in the production and refining of high sulfur
petroleum and in natural gas. It burns with a blue flame and produces Sulfur
Dioxide.
It forms an explosive mixture with air. The LFL is 4.3%
and the UFL is 45.5%.
28. 28
H2S or Toxic Gas ExposureH2S or Toxic Gas Exposure
Its odor is NOT a reliable warning signal because
higher concentrations of the gas temporarily
destroys the sense of smell. This is the primary
reason for employees not detecting the presence
of H2S and consequently inhaling a lethal
amount. The only positive means is by testing
with an approved H2S detector. DO NOT RELY
SOLELY ON THE SENSE OF SMELL!
