HIMA
Australia
have announced that they will be launching their new safety system "HIMax"
in mid 2008 and a change in Management - HIMA
Paul Hildebrandt GmbH + Co KG are launching a safety system which will set new
standards in performance, safety and availability within the process industry.
In the development of flexible and intelligent safety platforms, HIMA’s
special focus was on increasing the availability and profitability of process
plants. Offering unique features, HIMax ideally satisfies the global process
industry’s demand for increasing the profitability of safety-oriented
applications.
HIMA Australia are running 1-Day IEC/AS 61511 Safety Lifecycle
Awareness Courses in Brisbane
3rd June, Gladstone
5th June, Melbourne
25th June and Perth
16th July. The
outcome of the workshop will be an understanding of how to practically apply the
AS61511 standard. The workshop will cover the requirements of each stage of the
life cycle and how they apply to process industry projects today.
HIMA Australia are running a 4-Day TÜV FS Engineer Course in Melbourne
30th September - 3rd October - HIMA’s functional
safety course is a TÜV Rheinland Group certified training course for
engineering professionals. The course focuses on functional safety for the
process, oil & gas, and chemical industries according to IEC/AS 61508 /
61511 and gives engineers the opportunity to certify their functional safety
knowledge through TÜV.
| Functional Safety: A Practical Approach for End-Users and System Integrators- Tino Vande Capelle,Dr. M.J.M. Houtermans - The object of this paper is to demonstrate through a practical example how an end-user should deal with functional safety while designing a safety instrumented function and implementing it in a safety instrumented system. |
| Modern 2oo4-Processing Architecture for Safety Systems-Prof. Dr.-Ing. habil. Josef Börcsök -This paper provides an overview of two out of four system architecture and associated considerations. |
| Safety Bus Systems -Prof. Dr.-Ing. habil. Josef Börcsök - Modern distributed control systems are connected via bus systems, which need effective and uninterrupted communication between all subscribers. Therefore it is necessary for these communications to be fault tolerant and safe. For safety related systems, additional safety layers are required to fulfil these requirements. |

Introduction in Safety Bus Systems-Prof. Dr.-Ing. habil. Josef Börcsök - This paper discusses how modern distributed control systems are connected via bus systems, and need effective and uninterrupted communication between all bus stations. Therefore it is necessary that these communications are fault tolerant and safe. |
|
Safety Critical Software-Prof. Dr.-Ing. habil. Josef Börcsök -This paper discusses the methodical analysis of hardware architectures used in safety-related applications. It provides an excursus on a safe computer system’s software technology and specifies the overview in greater detail. |
|
Safety Systems -Prof. Dr.-Ing. habil. Josef Börcsök - This technical paper gives an excellent overview of Safety Systems covering development history, the fundamental considerations required, fault avoidance basis and measurement, fault control basis, along with external influences such as environmental demands, electromagnetic, mechanical and climatic considerations. |
| Comparison of PFD calculation -Prof. Dr.-Ing. habil. Josef Börcsök - This paper discusses the compares calculation methods. |

Sharing Control & Safety Instruments-Are your layers overlapping?-Dirk Schreier - Since its release as an Australian standard in July of 2004, AS61511 is rapidly being accepted and applied on Safety Instrumented Systems throughout the process industry. Principles such as independence between control and protective instruments have existed for many years; however they continue to often be overlooked even with the introduction of this standard. |
|
Risk Prevention and Mitigation-Where does gas detection fit in?-Dirk Schreier - It is quite common in today's process industry to see the terms fire and gas (F&G). These terms have been used hand in hand for many years and are also combined when referring to applications involving safety-instrumented systems. This article challenges the thinking behind this concept and demonstrates that although fire systems and gas detection systems both reduce risk; their methods are actually quite different. |
|
Legal Implications in Australia for Companies and Individuals under “Industrial Manslaughter”-Dean McNair - There has been a lot of discussion in Australia recently over proposed new occupational health and safety (OH&S) legislation which will include the provision to prosecute corporations and individuals under industrial manslaughter laws. State and territory governments are enacting these new laws in response to workplace deaths in the hope that it will force company directors and senior executives to improve the safety cultures within their organisations. |
| Safety standard IEC 61508 - Consequences for automation technology and implementation at HIMA -This white paper provides an overview of IEC 61508 and how HIMA have addressed it's requirements. |

SIL Assessments -Identification of Safety Instrumented Functions -Dirk Schreier - Since its release as an Australian standard in July of 2004, AS61511 is rapidly being accepted and applied on Safety Instrumented Systems throughout the process industry. AS61511 is a performance based standard with a risk-based approach to safety. Performance based standards are by nature very open to interpretation, and therefore allow for more than just one analysis technique. Some of the techniques currently applied in industry have some shortfalls in achieving the objective of the standard. This article looks at some common problems encountered during the analysis phase of the AS61511 safety lifecycle. |
| Programmable electronic safety system technical specification - HIMA Australia has made available a programmable electronic safety system technical specification for use by busy engineering offices who wish to utilise their time more effectively. The specification is suited to an Emergency Shutdown System application and is generic in nature so you can use it with any safety system vendor. The specification is also designed to be the backbone to the final release from your organisation after it is tailored to meet your specific requirements. You have to register to download this specification. |
| Communication with Safe Ethernet -Franz Handermann- The application of SafeEthernet paves the way for the open automation- and network systems of the future. |
| Safety
Considerations Dr. Josef Börcsök,-Statistical evaluation of HIMA systems in the context of IEC 61508. This article contains the first comprehensive description of IEC 61508-compliant calculation of errors in safety-related systems in general and describes how relevant values for the H41q/H51q systems currently available from HIMA can be calculated. |
| Critical Aspects of Safety, Availability and Communication in the control of a subsea gas pipeline- Requirements and Solutions - This is a large zipped file of 2.5 Meg so will take a while to download, however it is worth it as shows safety related satellite communication |
| Transporting gas - with safety first!-Automation of an ethylene pipeline |
| Integrated safety controllers with safeethernet - By combining the world's fastest safety controllers "HIMatrix" with the world's fastest safety bus "safeethernet", HIMA is creating a hitherto unknown level of flexibility for safety-related automation. This flexibility is the basis for the development of new potential. The current system limits of safety-related automation concepts are disappearing, paving the way for truly application-based safety solutions. This creates new potential for increasing productivity and reducing the total costs for safety technology. |
| Comprehensive safety solutions for the South Pars gasfield exploration-ESD, F&G and HIPPS systems from HIMA ensure maximum safety and plant availability. |
