In consideration of the current complex technological situation, UNIESSE NOVACHEM has established the ABIESSE Division that offers engineering services for process industries to design, implement and operate a Safety Instrument System (SIS) suitable to requirements and complying with safety international standards.
ABIESSE Division offers engineering services for process industries to design implement and operate a Safety Instrument System (SIS) suitable to requirements and complying with safety international standards.
ABIESSE determines, thanks to the knowledge of available technologies and familiarity with standards, the Automation Solutions that satisfy in the best way the SAFETY and RELIABILITY requirements, enabling Customers to protect their own plants and to increase the productive efficiency.
ABIESSE operates mainly in the following industrial fields:
We use in all phases of project Certified Software Safety Engineering Tools. Applying the included methodology and making use of reliability industry standards data handbook, we select and verify the integrity (SIL) of every instrument safety function (SIF).
We utilize our ability and safety analysis tools with your experience to analyse capital costs of different proposed automation solutions. Furthermore we are interested in existing plants, where using our analysis methodology we find weak points of current instrument safety systems and suggest adjustment in order to satisfy the safety requirements in accordance with the new rules.
We helps your engineers to design your safety architecture from sensors to logic solvers to actuators and also facilitates complete system integration with other foreign systems. Starting from concept we develop the Safety Requirement Specification (SRS) of every SIF fixing the maintenance strategy with procedures and interval of proof tests. According to safety standards and related architectural constrains we design the SIS, developing hardware and software specifications of all components, detailing the logics and factory/site tests procedures.
Each safety loop needs to meet the Safety Integrity Level (SIL) requirements. We use certificated safety engineering tools to verify, in reliable way, the PDF requirement of each SIF, taking into account repair and periodic testing concepts.
We can offer other safety lifecycle activities:
Furthermore we help your technicians and engineers to develop the procedures that are required to operate, maintain and periodically test your SIS.
The international standards now require that all the participants are competent to carry out the activities for which they are accountable. In order to support the acknowledge and correct application of standards we offer a variety of training course that can help technicians and engineers of all levels to update knowledge to the latest standards and state of the art techniques and methodologies available in this field.
IEC EN 61511: Functional Safety Introduction – (1 day)
Design and Engineering of Safety Instrumented Systems Complaint to IEC EN 61511 Standard – (4 days)
First Module: The risk and proper evaluation, methodologies of target SIL determinations and developing of Safety Requirement Specifications – (2 days)
Second Module: Conceptual and detailed design, architecture and technology choices, development, verify and validation SIL levels – (2 days)
Operations and Maintenance of Safety Instrumented Systems Complaint to IEC EN 61511 Standard – (2 days)
The recent standards IEC EN 61508 and IEC EN 61511 fix the methodologies to quantify the industry risk and to determine the safety instrument system performances to assure, in order to properly protect people, the environment and capital equipment. The uniformity and observance trend to international standards at the worldwide level is increasing the compliance with these standards is more and more called for by the multinational engineering companies and government agencies.
We analyze and compare alternative SIF designs and suggest solutions in accordance with standards to save implementation costs and/or improve the safety of the design as required.
