Why the Work Mattered

Purpose and Operating Need

Enhanced process security, reduced latency, and increased convergence speed by transitioning Engineering controls from IT to isolated OT fiber backbone.

Engineering Approach

Engineering Approach

Engineering scope: distribution switches Distribution Switching, managed access switches Managed Access Switching, Fiberoptic Backbone (OM3 50/125 multi-mode), VLAN Segmentation (IEEE 802.1Q), UPS-Backed OT Network IDFs, 10 Gbps East-West Backbone.

Outcome & Engineering Context

Outcome and Context

The documented architecture used a 10 Gbps backbone and 13 UPS units. The phase-specific execution record states approximately, with the remaining 20% requiring future commissioning. Improved isolation, latency and convergence within the supported scope; whole-network final commissioning is not asserted.

Roles & contributions
  • Project Ownership

    Full lifecycle project ownership

    Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

  • IT Team

    Project Team Contribution

    Team Contribution

    IT participated in lab/live transition validation and the controls-network cutover interface.

  • Fiber and Electrical Contractors

    Supplier Participation

    Vendor Contribution

    Fiber/electrical contractors carried field-installation work within the phased implementation; procurement and equipment sources included equipment distributor, network equipment supplier, Insight and network equipment supplier.

Project ownership and delivery context

Owned the full project lifecycle: capital planning and prioritization, need definition, feasibility and scope development, engineering and AFE justification, procurement and vendor coordination, construction sequencing and field oversight, commissioning, turnover, and post-startup support. Connected operating requirements with technical scope, funding decisions, execution readiness, and the needs of operations and maintenance.

Developed the fiber and managed-switch architecture, resilient power arrangements, configuration and rollback requirements, and cutover sequence. Network drawings, device labeling and validation connected the installation with operator and maintenance needs. The work included a 10 Gbps backbone and 13 UPS-backed resilience points.
