DeltaV DCS Project with Bus Technology:

The scope of the project included converting 1500 pneumatic I/O to DeltaV DCS. The project required DCS design, field engineering, panel fabrication, programming, factory testing, installation, loop check, and start-up support. The design phase also included design of new field instrumentation, procurement and commissioning of instruments. The field devices were all bus based, including Foundation Fieldbus, AS-i bus, and Devicenet. The project also featured configuration of an Aspen plant data historian connected to the DeltaV system via OPC.

DeltaV DCS Replacement Project:

In this project, we replaced a 1500 I/O Provox DCS with a DeltaV DCS. Tasks included DCS design, field engineering, procurement, panel fabrication, programming, factory testing, installation, loop check, and start-up support. The DCS configuration required us to develop Batch recipes using DeltaV Batch, and configure the Sequential Function Charts (SFC’s) that interfaced with the Batch system to control the unit. During the installation phase, we managed the removal of the existing Provox DCS hardware, retrofitted the cabinets with new back panels that contained the new DeltaV I/O, and re-connected the field wires.

Storage Tank Monitoring System Replacement:

The project included design, programming, factory testing, installation, loop check and startup support for replacing a Foxboro HTG system on ~170 storage and feed stock tanks. We accomplished measurement accuracy to the operator interface system equal to the storage tanks custody transfer meters. We implemented the project using SAAB radar, Rosemount transmitters and temperature elements, reading data to an existing DeltaV system with look up to individual tank strapping tables to calculate mass for high-high alarm backup system. We then communicated data via OPC link to Oracle/SAP Enterprise system for production planning, inventory management, shared tank use, and vendor supplied inventory replenishment.
