It enabled a new Enhanced Oil Recovery (EOR) study and has been used for annual updates of winter and summer case heat and mass balance (H&MB) documents. The Suite offers mutifarious applicationsįinally, a steady-state model of LPS, which proved vital to deliver the project, has also proved valuable. Similarly, the OTS that has been used to boost confidence of central control room operators is also being shared with other PDO sites. Its findings have been widely disseminated among other PDO teams. In particular, the dynamic mode has been used for a vital process safety study of brittle fracture of metallic materials across LPS, as well as continual troubleshooting and optimisation. Honeywell’s suggestions for improvements to the upgraded DCS logic have also been implemented in the actual plant. Unanticipated benefits include the identification of loop holes in upgraded logics for sour gas conditioning and pinpointing an incorrectly calibrated flow transmitter. The dynamic simulation model and OTS developed by Honeywell have brought significant benefits in the operational and control strategy, verification of logics for new units, and operator competence. PDO chose Honeywell to deliver all aspects of the project, using the UniSim Design Suite of process modelling tools, says a Honeywell case study. The project would cover all new facilities as well as existing units, and included in this, plan was an operator training station (OTS) to help staff prepare for an upgrade of the Distributed Control System (DCS) from Honeywell DT3000 to Experion during 2013, and boost operators’ efficiency and proficiency. In 2011 the plant was upgraded with new (double train) sour gas treatment facility.Īt the same time, the Lekhwair team committed to a project to develop a dynamic simulation model of LPS to help with troubleshooting and process optimisation. PDO’s Lekhwair Production Station (LPS) in the North-East of Oman is about 110 km from the the Yibal Government Gas Plant and its associated network. HONEYWELL has provided dynamic modelling and operator training for Petroleum Development Oman (PDO) using its UniSim design.
