Within a context of intense economic competition, in which countries with low labour costs are securing a growing proportion of global production, it is more than ever necessary to optimise the productivity of existing production lines and to control the investment associated with the implementation of new production tools.

APSYS accompanies the process industries in the assessment, levelling or design of their instrumented security chains, by integrating the applicable regulation constraints and the new SIL level objectives

Our actions cover the whole need, from the audit of the implemented solution to the reception of the modifications performed or even the new expended architecture.

They comprise:
  • the audit in the field of the existing instrumented chains and the verification of the documentary compliance
  • the allocation of the objectives and the calculation of the theoretical reliability levels according to the implemented architectures
  • the recommendation of the levelling actions according to the allocated objectives
  • if necessary, the definition of new architectures complying with the SIL levels
  • the assistance to the contracting authority for the implementation of new instrumented chains:
    • Definition of the demands and laying down of the specification
    • Analysis and validation of the suppliers answers and solutions
    • Assistance to the project follow-up
    • Analysis of the documentation
    • Definition and making of receipts

Our teams accompany those of our clients out in the field and commit themselves to being on their side until the end of the work.
