Role Overview

The Engineer III, Controls Service - Steam Turbine is an advanced engineering role with primary accountability for steam turbine controls service support. The role is centered on steam turbine control logic, sequencing, protection interfaces, valve and actuator controls, instrumentation, HMIs, alarms, control system hardware, and field implementation of controls modifications that improve steam turbine operability, reliability, safety, and maintainability. The engineer evaluates operating issues, develops and implements controls enhancements, adjusts control settings, supports logic and graphics changes, and recommends instrument and control system hardware or software modifications for steam turbine equipment and associated plant systems.

The role also supports integrated combined-cycle control interfaces with gas turbine (GT), Balance of Plant (BOP), and Heat Recovery Steam Generator (HRSG) systems when steam turbine operation depends on coordinated plant permissives, trips, runbacks, bypass systems, steam admission, condenser vacuum, feedwater, attemperation, or other plant support functions. In this role, the engineer performs complex assignments with limited supervision, makes technical recommendations, provides direct customer and field support, and mentors less experienced engineers.

Key Responsibilities

• Lead the evaluation and enhancement of steam turbine control system operations as the primary focus of the role, including steam turbine start-up, loading, unloading, shutdown, trip logic, protection interfaces, valve control, auxiliary sequencing, alarm response, and field implementation of control logic or graphics modifications.
• Provide technical support and dispositions to resolve emergent steam turbine controls issues during outages, commissioning, start-up, troubleshooting, and operating events, including time-critical support for critical path activities when required.
• Serve as a steam turbine controls subject matter contributor for service engineering support, with emphasis on interpreting steam turbine control narratives, functional logic, control drawings, alarm and trip logic, sequencing, permissives , instrumentation feedback, and control system interfaces required to support outage, commissioning, and operational troubleshooting.
• Lead the preparation of functional logic descriptions in text form by extracting functional requirements from P&IDs, system descriptions, component specifications, operating procedures, sequence documents, and other plant design documents to define the objective, reason, and technical basis for control logic changes.
• Lead the preparation and review of design documents including SAMA logic drawings, control narratives, specifications, work procedures, checklists, validation plans, test plans, commissioning support documents, and as-built documentation in accordance with approved company procedures.
• Analyze operational data from steam turbine controls, turbine auxiliaries, valve position feedback, trip and alarm history,…
