Industrial Process Maintenance Torulf Mollestad, Ph.D, Principal Consultant Altran N

The goal To avoid process problems … 22 shutdowns of the LP separator … by considering events in process data high! unstable! Gas flow J_43_FI_81164 low! time

119 tags selected; e.g. : Templates: Event/property tags: under2p low J_43_FI_81164_under2p Tags: : over98p J_43_FI_81164_over98p high : EKOJ Ejector J_43_FI_81164 v_gt98p unstable J_43_FI_81164_v_gt98p LP Gas Flow : sharp downward j_lt5p J_43_FI_81164_j_lt5p : j_gt98p sharp upward J_43_FI_81164_j_gt98p : : :

Precursors to problems B_43_FX_5682 low - Eld gas PV Out C_43_PT_12513 low - EKOC Prod line 2 E_43_PT_18335 unstable – Valve 335 pressure F_43_PT_12161 unstable P_43_PT_7020SI unstable - EKOJ LP Scrubber Level

Rules and usable patterns Rules generated, e.g.: IF  J_43_XI_21091VF_v_gt95p and  J_43_LIC_00419SP_j_gt95p THEN  low_water_closed(0.5, 0.7) (within 0.5hour, probability 0.7)

The expert: Rule visualisation

The operator: Supervision and Diagnostics

• The solution comes up with a set of rules • Each rule warns against a problem coming up • Rules = model => set in production
