Title: The Case for a Professional Safety Society in Qatar ABSTRACT: The last 12 or so years have seen tremendous growth in Qatar, on top of oil & gas production, processing and real-estate, the economy has been diversified to include manufacturing, excellent academic institutions, effective government engagement, dynamic healthcare sector and a global 5 star airways. This setup begs the question why is there a ap in communication between all these HSE stakeholders, the need to provide a shared platform of dialogue and networking becomes apparent. Therefore there is a big potential for establishing a local section for the American Society of Safety Engineers in Qatar. The HSE industry has evolved and reached a recognized level of maturity in this country that the lack of such a society is urgently needed, if not required. The benefits of joining a professional society will be examined such as providing networking opportunities and online membership boards where you can post questions, read peer publications, and interact in other ways that can lead to job offers, training, and more. The requirement to having a successful professional association that combines its goals of being relevant to the industry and providing cost benefit value to its members will be discussed.

Title: Process Safety Management – An HSE Foundation ABSTRACT: Despite recent advances in equipment design and control systems and the increased focus on safety and risk management, industry continues to experience major accidents. However, industry is not learning from past disasters well enough to prevent their reoccurrence because the focus is too much on occupational safety, and not enough on Process Safety. Dolphin Energy Limited (DEL) has been successful in implementing good HSE practices that reduce Total Recordable Incident Rates (TRIR) to levels favorably comparable to those of industry. As DEL gained operational experiences, it was recognized that measuring HSE performance using TRIR was not a good indication that Process Safety issues were being managed properly. Thus, the DEL Process Safety Management Strategy was implemented to serve as the foundation for HSE programs. This strategy aims to ensure that risks arising from hazardous processes are properly controlled to reduce impacts on people, property, environment, revenue, and DEL reputation. The strategy includes: 1. Making Process Safety everybody’s business as is the case for personal safety and environmental protection 2. Raising Process Safety awareness 3. Integration of Process Safety with QHSE MS 4. Process Safety Lagging and Leading Metrics reporting 5. Safety Critical System Performance Standards and Verification 6. Risk Revalidation 7. Internal and External Process Safety auditing 14

Title: Safety Case Framework in Qatar’s Energy Industry; Technical HSE Framework and the Safety Case Approach ABSTRACT: The Oil and Energy Industry represents the backbone of the State of Qatar economy with needs to be regulated and managed to mitigate significant and intolerable safety risk. The role of the Health, Safety and Environment Regulations and Enforcement Directorate (hereinafter HSE DG) is to assure the stakeholders, investors and the State level that Major safety risk to the State of Qatar Energy Industry is being appropriately managed whilst not forgetting the environment and occupational health and safety risks issues. 15
Speakers The HSE Regulations and Enforcement Directorate (DG) “Technical HSE Framework” has been developed to facilitate Directorate (DG) in regulating the State of Qatar’s Petroleum and Industry sector. This Framework focuses on the significant health, safety and environmental risks that could impact at state level; hence regulatory framework is required to address the “Major Hazards Management”. A major accident at any one of Qatar’s installations is likely to entail material losses, damage to the environment, the State economy, local communities and society, while the lives and health of workers may be put at risk. The likelihood of a major accident in Qatar needs to be reduced. The Safety Case approach, which will be the driving principle behind the regulatory regimes, forms the cornerstone of the Technical HSE Framework with key outcome to build safety management capacity and the safety culture within the State of Qatar. The HSE Directorate (DG) will work with other statutory and regulatory bodies in the State of Qatar in order to increase and strengthen the requirements of the legislation. The purpose of a Safety Case is to demonstrate the safety arrangements for a designated “Installation” and how these arrangements ensure that the risk associated with the activity remains at a level that is ALARP. The benefits and value added to the State of Qatar are obvious and can be summarized as following – enhanced health, safety and environmental performance of the Oil & Gas Industry and population, shareholders and investors confidence that industries are adopting the world class HSE practices. The State of Qatar will continue to build upon its role in the regional and international community as a stabile and reliable partner in Oil and Energy Industry Sector by implementing HSE culture based on the highest international standards and best approach. The HSE (DG) Directorate will do its outmost best to contribute to this effort.

Title: Integrity Management Of Critical Safety Systems ABSTRACT: A main goal of process safety and asset integrity management (AIM) programs in the oil and gas industry is the prevention of major accidents. As originated in the UK safety case approach and expanded upon elsewhere, it is realized that certain process equipment systems, if they failed, could cause a major accident. These systems are often called health, safety and environment (HSE) critical systems, or critical safety systems (CSS) for short. Obviously effective maintenance and integrity management of such systems is a vital process in preventing major accidents. Identification of CSS is a critical first step, with tools such as hazard registers and decision trees often deployed to accomplish this. One goal in this process is to limit the number of CSS, so that they can truly be prioritized. Once identified, performance standards for CSS should be developed so that at any stage in their life, fitness for purpose can be assessed. Maintenance, monitoring and testing regimes can then be put into place so that fitness for purpose is maintained. Execution of these is greatly facilitated through the use of computerized maintenance management systems, which also allows rapid assessment of work progress. As such, key performance indicators (KPIs) can be defined and monitored as a means of assessing CSS status. Other considerations to be carefully managed include over-rides / dispensations, change management and verification / audit of CSS. The above aspects of CSS and common pitfalls in this management process are presented, with examples drawn from actual major production operations.

Title: Process Safety for a Sustainable Future ABSTRACT: Process Safety has become one of the key terms to describe approaches for preventing major accidents in the petrochemical business. But what does being good at process safety involve? There are four main considerations: design; asset integrity; operating discipline; and the management system that binds the first three together. ConocoPhillips supports the position shared by the Center for Chemical Process Safety and others that a compelling business case exists for strong, effective leadership across all elements of process safety. Corporate responsibility, risk reduction, business flexibility, and sustained value are all desirable outcomes of well-conceived and effectively executed process safety programs with key performance indicators. To further support process safety education and training at all levels, ConocoPhillips is partnering with Texas A&M at Qatar at this symposium. ConocoPhillips also is promoting R&D to help our company better understand root causes of past process safety incidents related to technical and human performance. At ConocoPhillips, we are incorporating new ideas and efforts in all these areas. We also are binding the work together in a management system that drives collaboration, knowledge sharing and active monitoring of day-to-day activities. When we learn from history and from each other, we believe we can create a future without serious process safety incidents.

Title: Simulator Training for Operators and Engineers ABSTRACT: Operations jobs are complex and a staff of well-trained operators and engineers are essential for safe and efficient plant operations. This presentation describes a comprehensive methodology called INSTO™ which uses Simulators, Instructor and Student Workbooks, and innovative classroom techniques for “hands-on” and “minds-on” training of operators and engineers. The INSTO™ methodology is designed for small group instruction which allows for maximum student participation. Each student has access to their own Simulator. The learning is mostly student-driven, with the instructor playing the role of mentor and coach. Most training exercises begin with the student making a written prediction about normal plant operations or responses to an upset, followed by operating the Simulator and observing and recording the actual plant behavior, and lastly comparing and discussing their predictions to actual plant behavior. Top operators and engineers rely heavily on their own mental model of the process, especially during upsets and emergencies. The INSTO™ Simulator training methodology is designed to build and strengthen these mental models, and also help operators and engineers develop and improve their troubleshooting skills. There are two types of course assessments. The first is a comprehensive grade based on the students’ scores in all the individual exercises in each of the 5 INSTO™ elements – I/Identification, N/Normal Operations, S/Start-up and Shutdown, T/Troubleshooting, and O/Optimization. The second is a self-assessment covering 30 aspects of Plant Operations within the following 6 categories: Console Manipulation, Procedural Adherence & Compliance, Situational Awareness, Decision Taking, Communications and Cooperation. 19

Title: Development of Focused Training Programs And Decision Support Systems On Risk Assessment ABSTRACT: Risk Assessment is a continuous evolving practice and concept that deals with processes which significantly impact human and ecological health, economics and decisionmaking. Though risk assessment is based on a number of uncompromising principles, the methodology to apply these principles can considerably differ from processes to processes. Therefore, Risk assessment professionals, freshmen and “sidekicks” face a critical need to have sufficient, up-to-date and state-of-the-art training. This is more eminent nowadays where the staffs of agencies and corporations have to effectively and efficiently manage the risk and to safeguard environmental and public health. Unfortunately, it is not possible for them to comprehend the principles and apprehend the impacts solely by attending “customized training courses”. The new era of risk assessment training demands the development of focused training programs instead of providing trimmed and reduced versions of existing ones. This way, a number of risk experts first analyse or even setup the basis of a risk assessment study for the specific processes or group of processes. Afterwards they form the training material and guides for either face-to-face or asynchronous (e.g. eLearning) programs. Finally and if necessary a decision support system is established in order to assist stakeholders on common activities, special events etc. The presentation provides some of the important factors and stages on developing a focused training program on risk assessment and a number of specific case studies i.e. small industries, new engineers and the military. 20

Title: Design of Fire Protection Systems for LNG Facilities ABSTRACT: As LNG facilities around the world become more common and are storing/processing greater quantities of product it is essential that any fire incident can be quickly mitigated by means of Fixed Fire Protection Systems. These need to be correctly designed to bring the incident under control so the risk of injuries and plant damage is minimised. As the international standards for such Fire Protection Systems provide limited design information, Angus Fire has carried out extensive test work to establish the best methods of protecting these highly volatile hazards. The presentation will summarise the findings of the test work and provide recommendations for System Design based on these findings. The aim of the presentation is to give the audience an overview of systems and equipment that could be deployed together with the system design criteria. The presentation will also include advice on checking the integrity of existing systems. From our experience there are many LNG facilities around the world that have insufficient protection because of poor design and/or equipment selection.

Title: CO2PIPEHAZ: Quantitative Hazard Assessment for next generation CO2 pipelines ABSTRACT: As part of the Carbon Capture and Storage (CCS) chain, CO2 pipelines are considered as the main method for transporting huge amounts of captured CO2 from fossil fuel power plants for subsequent sequestration. Given that CO2 is an asphyxiant at concentrations greater than 10% v/v, the safety of CO2 pipelines is of fundamental importance and indeed pivotal to the public acceptability of CCS as a viable mean for tackling the impact of global warming. This paper presents an overview of the main findings of the recently completed European Commission FP7 CO2PipeHaz project focused on the hazard assessment of CO2 pipelines. The developments of the state-of-the-art multi-phase heterogeneous discharge and dispersion models are given special consideration given that this data forms the basis for emergency response planning and determining the minimum safe distances to populated areas. Model validations are based on both laboratory and large-scale field trials using a unique CCS facility in China involving the rupture of an especially constructed fully instrumented 250m long, 0.23m i.d pipeline containing dense phase CO2. The understanding gained based on this work is used for evaluating the adequacy of control measures in CO2 pipelines, with best practice guidelines proposed.

Title: Process Safety Research Agenda for the 21st Century ABSTRACT: Process safety is an evolving field whose importance becomes evident only after tragic disasters occur. During the past decades, many primary theories and technologies have been studied, invented and applied. However, we have to continuously develop advanced methods for more complex problems that remain in science, technology and organization. To address these issues, the Mary Kay O’Connor Process Safety Center convened an unprecedented gathering of academia and researchers in October 2011, to develop the “Process Safety Research Agenda for the 21st Century.” The presentation will share the results of the deliberations where 19 areas areas were identified and prioritized in terms of a set of criteria to focus future research in Process Safety.

Title: Source term modelling for LNG spills on land ABSTRACT: Potentially severe consequences associated to accidental liquefied natural gas (LNG) spills have motivated a number of different studies, including experimental work, towards their prediction. Most of these studies focus on vapour dispersion, however there is limited information regarding source term of vapour formation, which includes liquid spill, pool spreading and liquid vaporization rate. Existing models of the source term utilize semi-empirical equations and are built based on non-comprehensive data derived from non-cryogenic liquid spills, like oils, which do not necessary represent cryogenic liquid spill well. There are needs of further improvements to understand physical phenomena of vapour formation from cryogenic liquid spill and to quantify the most important parameters that can affect them. The vaporization of cryogenic liquids is governed by the heat transfer phenomena including conduction, convection and thermal radiation mechanisms. The present work investigates the contribution of these different heat transfer mechanisms to the vaporization rate of cryogenic liquid through the series of small and medium-scale, well-controlled and instrumented experiments performed with liquid nitrogen (LN2). The vaporization rate of LN2 was measured and correlated to the individual contributions of conductive, convective and radiative heat transfer. The experiments on convection showed that this heat transfer mode can play a significant role in the vaporization rate of the cryogenic liquid. In these set of experiments, its contribution to total heat flux to an LN2 pool spilled on a concrete surface was measured to be as high as 30% after 10 minutes for moderate wind speed of 2-3 m.s-1. The experimental data also showed that the sidewalls of the liquid containment may play a key role in the resulting amount of convective heat transfer and indicates that walls or fences could be used as a good mitigation method. It was observed that the radiative heat absorbed by the LN2 pool during the experiment represent only 50% to 65% of the incident radiation that would reach the LN2 pool surface if no vapour was present. This is attributed to the absorption and/or reflection of the radiation by the vapour. 24

Title: Broadening the Safety Culture: Gaining Employee Ownership of Process Safety ABSTRACT: While personnel injury and illness rates in the petrochemical industry have shown strong positive trends over the past several years, process-related incidents and events, many of them quite significant, have continued to occur with little or no change in rates. Process safety trends such as these show that believing superb personnel safety performance is a reliable gauge of comprehensive safety performance can be a deadly mistake. In particular, process incidents reveal the need to combine strong personnel safety performance with excellent process safety management programs founded on recognized engineering principles to achieve consistent comprehensive safety performance. However, the variables posed by human interfaces with well-engineered process safety management programs have proven a difficult challenge. Removing uncertainty posed by inconsistent human behaviors remains one of the greatest opportunities for improving process safety program performance. The key to successfully meshing engineered solutions with human behaviors is getting employees engaged and involved in actively managing process safety performance. This presentation provides a case study in establishing employee involvement in and ownership of process safety efforts thereby achieving significant reductions in process safety events and increasing positive results in comprehensive safety performance.

Title: The Time to Learn to Dance is Not the Night Before the Party ABSTRACT: Prudent companies will acknowledge the value of proper independent, unbiased incident investigations which ensure that there is maximum learning from events and opportunities taken to update their risk assessments, training programmes, systems and controls to take cognisance of them. They will take the necessary steps to assess if the organisation has considered whether attitudes, policies or accepted practice encouraged or produced tolerance of the failure. Safety Management Systems and Loss Prevention Processes are critical elements of any robust investigation. Establishing a culture that withstands the scrutiny of intrusive investigation should be standard requirements for companies that take the protection of their people seriously. Prevention is not a passive process, it is a dynamic activity. Forward thinking organisations are always thinking out of the box and considering ways in which to reduce their vulnerability. It can be as simple as black and white if an organisation invests the time in good quality proactive audits of their processes and procedures. Significant issues will emerge around which they can take positive action to prevent becoming critical incidents requiring lengthy reactive investigation. 26

Methods The specific data that were required from the calorimetric tests were the following: • The onset temperature for the exothermic runaway reaction. • The rate and quantity of heat released as the runaway reaction proceeds. • The rate and magnitude of pressure generated during the runaway reaction. These data were then to be used to calculate the required vent size and scale it up for the pilot reactor.
Temperature (K)
Abstract Exothermic reactions that undergo uncontrolled self-heating as a result of loss of cooling lead to thermal runaways. This is of concern especially during the scale up of the cooling system for a chemical vessel designed to carry on an exothermic processes. The heat produced by a reaction is proportional to the volume of the reaction mixture, while the cooling capacity is a function of surface area of the vessel. Under thermal runaway the reactor behaves as an adiabatic system. Vents are passive protective layers against the effects of thermal runaways. Different peroxide decompositions (highly exothermic reactions) were studied using adiabatic calorimetry techniques to obtain the necessary parameters outlined in the DIERS methodology for vent sizing.

ABSTRACT: Understanding safety culture is part of the journey towards improving organisational reliability. Organisation’s have responsibilities for the management of their risks, and to ensure adequate and appropriate risk mitigation. Central to the effectiveness of safety management is the concept of safety culture. This presentation covers HSL’s approach which shows the steps to becoming a successful and highly reliable organisation. The first two steps, Understand SMS and investigate safety culture, are about understanding the status quo, determining whether the processes, standards and systems are adequately designed and implemented. The assessment of safety culture will provide information that will help you to understand the efficacy of risk management and safety management systems and prioritise improvements. The next step following ‘Understanding’ would be to ‘Improve’ which could involve developing KPIs and procedures, or improving accident investigation, based on signposting from your safety culture evaluation or your SMS audits. Other steps could improve development of behavioural safety programmes to address unsafe behaviours, once organisational readiness has been determined and tactical improvements derived from the safety culture assessment have been delivered. The endpoint of this journey would be an organisation well on the road towards being labelled a ‘High Reliability Organisation’.

WHY DO WE NEED TO KNOW ABOUT DUST EXPLOSIONS?
RESULTS: WHAT WE CAN WE MEASURE?
Dust explosions accidents are very well known in the coal industry (Fig. 1), but not many people know that it may happen in others. As a matter of fact it occurs very often in the wood, paper and food industries (Fig. 2). One of the examples is the explosion at the Imperial Sugar company in 2008 (Fig. 2). This explosion caused 14 deaths and 38 injured, among which 14 with serious life-threatening burns.
The 20 liter dust explosion sphere is used as a standard test to determine the following important parameters for dust (and gas) explosions (Fig.3): Maximum explosion pressure, Pmax Maximum rate of pressure rise, (dP/dt)max Time to maximum pressure rise, t1 Time to maximum pressure, tmax Kst (dust deflagration index) Lower and Upper Explosion Limits (LEL and UEL) P (bar) Pmax dP dt max
