Designs and oversees rotating machinery like compressors, turbines, and pumps for maritime cryogenic systems, ensuring technical specs, vendor compliance, and project delivery.
As part of InnoTech, the AL Maritime activity connects a wide range of global markets to essential molecules across borders and oceans. Air Liquide Maritime is organized along four business units, namely Offshore Energies, Cryogenic Supply, Global Rare Gases and Global Helium, and is also supporting OCEOS, a joint venture to offer CO2 shipping and barging services for CCS projects across Europe. The organisation has grown significantly over the last few years and regroups 10 sites located in 9 countries with more than 200 employees.
Air Liquide Maritime Sdn Bhd specializes in cryogenic tank and equipment rental for the offshore and maritime industries as well as in cryogenic transport of molecules, and provides a full range of repair and testing services.
Mechanical Packaging & Detailed Design
Perform structural analysis including lifting lugs calculations, and structure to withstand transit, seismic, and operational dynamic loads.
Generate detailed system assembly drawings, process flow diagrams, fabrication drawings, Bill of Materials (BOMs), and technical specifications for the modular skid assembly.
Create and review the submission of design documentation.
Integrate instrumentation, valves and electrical junction boxes onto the skid package in compliance with hazardous area classifications.
Lead the development of standardized mechanical layouts and modular designs for turboexpander skid systems (including lubrication consoles and dry gas seal systems) to improve engineering efficiency, reduce lead times, and lower manufacturing cost.
Technical Specifications & Vendor Management
Draft comprehensive technical specification sheets for turbo expanders and auxiliary equipment based on customer’s process requirements and Aero design.
Perform and validate critical mechanical, fluid, and thermal calculations for turboexpander auxiliary systems, including piping hydraulics, pressure drop analysis, heat exchanger sizing, safety relief valve (PSV) sizing, and structural lifting/loading criteria in compliance with applicable standards
Evaluate vendor proposals, perform technical bid tabulations, and serve as the primary technical point of contact with AL Turbo team/division.
Review performance curves, rotordynamic limits, and system P&IDs provided by AL Turbo and auxiliary equipment suppliers to verify design integrity and enforce alignment with company and client requirements
Participate in Factory Acceptance Testing (FAT) and mechanical running tests at vendor facilities, as needed.
Cross-Functional Coordination & Safety
Collaborate closely with various engineering disciplines (process, instrumentation, electrical) and project management to ensure seamless boundaries, interfaces and adherence to project goals and objectives.
Lead and participate in HAZOP, and 3D Model Reviews to guarantee the inherent safety, operability, and maintainability of the skid package.
Ensure all designs rigorously adhere to Air Liquide's industrial safety guidelines and environmental regulations.
