About the role

Position Summary

The Senior Project Engineer – Mechanical facilitates the development a small portfolio capital and OPEX projects for the Geismar site. During the development of projects, they will perform engineering tasks including engineering analysis of drawings, system and functional requirements, hazard analysis and vendor performance specifications. This will involve collaborating with multiple partners from all levels of the organization to determine data and requirements for technical solutions. A key aspect of these activities includes a focus on improving life-cycle costs by evaluating emerging technologies and technical solutions and ensuring quality, integrity, safety and regulatory compliance of projects in accordance with industry code and Methanex standards and procedures.
For capital projects this includes the initial 3 stages of a capital project (Visualization, Conceptualization and Basic Engineering), as well as monitoring the successful completion of the detailed engineering, utilizing the Manufacturing Capital Management Process (MCMP). Once detailed engineering is complete and capital funding is granted, the Project Engineer will provide support to the execution lead and follow through with formal project closeout activities.
OPEX project development will be more tactical in nature than capital projects and may include analysis of design issues related to pipe and equipment stresses, rotating equipment troubleshooting or to provide solutions for problems presenting operational, safety or maintenance challenges through the utilization of a Management of Change (MOC) process.
The Senior Project Engineer provides Q/A support to peer Project Engineers on other assigned capital and OPEX projects. They are also responsible for performing Mechanical Engineering design and pipe stress calculations to support the site CAPEX and OPEX portfolio.

Position Responsibilities

• Utilizes the MCMP procedure to progress a project from initiation to completion.
• Manages technical small to mid-sized capital projects from Stages 1 to 3 as per MCMP.
• Supports the execution leads on projects progressing from Stage 4 to close-out as per MCMP.
• Provides Q/A support to other Project Leads and their portfolios.
• Leads the selection of alternative studies during Stage 2 as per MCMP.
• Manages contract engineering services related to conceptual studies and Front-End Engineering Design (FEED).
• Leads the request for funding (AFE) on capital projects assigned as per MCMP.
• Estimates budgets and time scopes for each project.
• Works in collaboration with local engineering contractors on the development of engineering packages.
• Ensures all mechanical/piping and related tactical issues such as small modifications, troubleshooting and OPEX projects that arise at the Geismar facility are evaluated from the technical/mechanical engineering perspective.
• Ensures all mechanical/piping project functions are integrated effectively across all relevant work groups.
• Develops scopes of work for mechanical/piping OPEX modifications, following the global Management of Change (MOC) process.
• Effectively collaborates with the Maintenance Department on the troubleshooting, assessment, evaluation, inspection and recommended solutions related to static, rotative equipment and mechanical related issues in general.
• Contributes to the design approval process on assigned OPEX projects and small modifications to ensure input is obtained from the appropriate disciplines and changes are made to the design as required.
• Helps to ensure the systems to maintain and store mechanical/piping drawings by the drawing office are in compliance with the Methanex USA procedures and standards.
• Supports plant Operations, Maintenance and other stakeholders with mechanical engineering services requests related to safety and reliability vulnerabilities in the plant. These may be identified through various work processes including work orders, incident investigations or technical service requests.
• Designs and develops mechanical systems, keeping in mind the budget, timelines and other essential resources.
• Reports to the Engineering and Projects Lead regarding the status of each project.
• Uses CAD and 3D CAD programs to plan mechanical design projects.
• Troubleshoots problems and devises solutions to resolve them.
• Performs and checks piping stress analysis calculations, conducts studies and prepares reports.
• Prepares critical line list, piping stress analysis specification and technical specification for Spring Hangers/Supports datasheets.
• Selects types of support restraints and special support at feasible structural locations.
• Provides piping design loads on process structures, pipe racks, etc., to the civil/structure department.
• Reviews piping support designs and provides design support to piping designers.
