The position requires strong technical expertise in LNG process design, EPC project execution, and hands-on experience supporting commissioning and startup of major LNG facilities.

Position Overview

Your responsibilities may include:

Conceptual Development, Pre-FEED & FEED Phases

* Participate in the development and definition of overall LNG project and process design basis.

* Provide technical guidance and process engineering support to EPC contractors, and client teams.

* Perform LNG liquefaction process concept selection studies and refrigeration compressor driver selections

* Develop process configuration according to process design basis

* Identify optimal LNG process configurations to improve efficiency, reliability, and operability.

* Perform LNG plant design case and rating cases simulation

* Prepare technical reports and evaluations comparing alternative process schemes.

* Support validation of project economics through process design inputs and performance analysis.

* Develop licensor process design package (PDP), including:

* Process description with control philosophy

* Block Flow Diagram (BFD)

* Process Flow Diagrams (PFDs) and Heat & Material balances

* Material Selection Diagrams

* Process equipment sizing and datasheet

* Process Control Narratives

* Preliminary Piping & Instrumentation Diagrams (P&IDs)

* Review and approve technical specifications and datasheets for long lead-time process equipment.

* Coordinate with the EPC contractor to establish accurate preliminary hydraulic models and line sizing.

* Participate in refrigeration compressor optimization with the compressor venders and EPC contractors

* Participate in P& by line review

* Participate in process safety and risk assessments, including HAZID and HAZOP workshops.

* Support cost estimating activities, project scheduling, and review/approval of engineering deliverables.

FEED, EPC Execution & Post-Startup Phases

* Maintain overall progress, technical integrity, quality, and accuracy of process engineering deliverables throughout FEED and EPC execution.

* Ensure compliance with company and project-specific engineering standards and minimum requirements throughout the design process.

* Update, review, and finalize detailed process design deliverables, including PFDs, UFDs, H&MBs, and P&IDs.

* Prepare and/or verify process design and rated-case simulations using industry-standard tools (e.g., Aspen HYSYS).

* Prepare and/or check process equipment datasheets and specifications.

* Develop and/or verify detailed distillation column hydraulic designs, including tray or packing ratings.

* Participate in multidisciplinary design reviews, including:

* P&

* HAZOP and SIL studies/workshops

* 3D Model Reviews

* Coordinate with the EPC contractor to ensure accurate and appropriate line sizing, routing, and pressure drop profiles across process systems.

* Review vendor and mechanical datasheets to verify compliance with process requirements.

* Participate in manufactured equipment reviews, module check-outs, and P&-downs.

* Provide direct support during commissioning, startup, and initial operations, including on-site assignments as required.

* Troubleshoot and resolve process and operational issues during startup and post-startup phases.

* Perform revamp and debottlenecking studies to improve plant capacity, availability, and operational performance.
