Dynamic Reconfiguration of Safety-Critical Production Systems

This paper deals with some of the latest developments and serial production applications at obz innovation gmbh. With three serial production systems and one for the R&D department, obz innovation gmbh is the leading supplier of cold sprayed coatings. The development of the well known serial production process of the sinusoidal copper coating for hybrid cars is explained. Furthermore our ferritic chromium steel induction coating and our new application paths in this area, an immanent temperature limitation function for safety critical reasons, is shown. An example for a field of research actually examined at obz is power electronics with cold sprayed circuits on an insulating ceramic coating with potential use in fields like automotive and many others.

Different Levels

The chapter deals with UML-based design of Reconfigurable Embedded Control Systems (RECS). The different software architectural configurations of the control system are described as a set of inter-connected software components. A software agent is defined in order to handle dynamic reconfiguration scenarios. The agent has the ability to interact with users and to monitor the system’s environment in order to apply valid reconfiguration scenarios at different levels of the system’s architecture. In order to address all possible forms of reconfiguration, three architectural levels are defined. A set of UML-compliant metamodels are proposed in order to describe the knowledge about the reconfiguration agent, the system architecture, the reconfiguration scenarios, and the reconfiguration events. The validity of the reconfiguration scenarios is checked by using a UML-based environment that allows evaluation of the architectural and reconfiguration constraints. The proposed reconfiguration approach is applied to two industrial production systems, FESTO and ENAS.

Technical Solutions

The objective of this paper is to provide operators of floating production systems that utilise dynamic flexible risers an opportunity to review the technology and procedures adopted by PGS Production. These procedures were utilised in order to verify/re-use the damaged/seawater annulus flooded Banff risers. Most of these risers were also classified as being safety critical. The scope of the work carried out covers the development of a seawater displacement treatment system using an inhibitor fluid. The feasibility and efficacy of the flushing treatment were rigorously developed based on hydraulic test analysis using sections taken from an actual flexible riser. An extensive corrosion fatigue-testing programme using seawater/CO2/inhibitor was carried out to establish optimal safe service lives for the “damaged and treated” case for these risers. This paper presents the successful results from this work covering the development of the remedial treatment process and the resulting corrosion fatigue work that has been conducted.
