Foundation fieldbus economics comparison

This paper will provide a life cycle cost comparison between installations of three different control system configurations, 1. Conventional analogue instruments. 2. HART(TM) protocol instruments with a parallel asset managem ent system. 3. Foundation fieldbus installation. Engineering, procurement, construction, commissioning and ongoing maintenance costs will be included as part of the analysis. Data for the analysis includes equipment from mult iple manufacturers so a range of expected expenses will also be provided to indicate the sensitivity of the economic calculations to supplier. All cal culations will be based on the median equipment values. (C) 2000 Elsevier S cience Ltd, All rights reserved.
