Pipeline System Planning Engineer (LNG)

Requisition ID: 21682 Date: 30 Sept 2026 Location: TX, US, 77056 Company: Woodside Energy Ltd About Woodside We know great results come from our people feeling valued, getting the support they need to reach their full potential and working in a psychologically and physically safe work environment. We recognise that enduring, meaningful relationships with communities are fundamental to maintaining our licence to operate. Sustainability performance is fundamental to the long-term success of our business. We use technology to help reduce emissions at our operations. We are also working to improve energy efficiency, offset emissions, reduce emissions intensity and explore options for lower-carbon energy. Woodside led the development of the LNG industry in Australia and is applying this same pioneering spirit to contribute towards future energy challenges globally. Refer to our corporate website for more information about our different locations and projects: https://www.woodside.com/what-we-do About the Role We are seeking an experienced engineer to lead the development and operationalization of an integrated LNG feedgas forecasting, flow assurance, and optimization capability supporting Louisiana LNG. This role sits at the intersection of natural gas transportation, LNG operations, hydraulic modeling, gas quality management, commercial optimization, and operational decision support. The successful candidate will be responsible for understanding how upstream pipeline, storage, gas quality, and commercial activities influence LNG terminal operations and developing predictive tools, models, and workflows that improve operational reliability and commercial decision making. This position will serve as the primary technical lead supporting the evolution from reactive feedgas monitoring to predictive feedgas intelligence, enabling earlier visibility of changes in gas quality, pressure, flow, and supply reliability across the upstream transportation network. The capability is intended to support nominations, contingency planning, LNG operating decisions, and feedgas optimization. Duties and Responsibilities Feedgas Flow Assurance & System Optimization Develop and maintain hydraulic and flow assurance models for interstate and intrastate natural gas transportation systems. Perform steady-state and transient hydraulic simulations to evaluate system performance under normal and abnormal operating conditions. Analyze the impacts of compressor outages, pipeline maintenance, storage withdrawals, receipt point disruptions, and market changes. Support short-term and long-term gas supply planning activities through system modeling and scenario analysis. Identify capacity constraints and develop mitigation strategies. LNG Feedgas & Process Optimization Analyze the impact of feedgas composition, pressure, and flow variability on LNG facility performance. Evaluate feedgas quality trends, including nitrogen, BTU, Wobbe, CO₂, C6+, and other critical parameters. Support LNG operating decisions through forecasting and scenario analysis. Collaborate with LNG Operations to optimize facility performance, operating envelopes, and feedgas management strategies. Support development of predictive capabilities for gas quality and facility performance forecasting. Commercial & Gas Supply Planning Support Support nomination, scheduling, and gas supply optimization activities. Evaluate transportation, storage, and supply alternatives. Analyze impacts of market conditions, transportation constraints, and supply interruptions. Work closely with commercial teams, schedulers, gas controllers, and supply planners. Support month-ahead, week-ahead, day-ahead, and intraday gas supply planning activities. Operational Intelligence & Data Analytics Integrate operational, commercial, SCADA, gas quality, and market data into decision-support workflows. Analyze forecast versus actual performance to improve predictive accuracy. Develop automated reports, dashboards, and operatio…
