The Nord Stream Pipeline is a subsea natural gas pipeline transmission system from Russia to Germany comprising of two parallel pipelines. Each pipeline has a diameter of 48” and a length of 1 220 km. The twin pipelines are designed for complex operation with a staged design pressure of 220/200/177 bar and a transport capacity of 55 billion m³/year.
IMPaC has provided engineering services to Nord Stream from the early stages of the project which included Authority Engineering & Permitting support, preparation of detailed documentation and maps for the Construction, Commissioning and Operation of the pipelines and for the national & international permitting processes. Within the project IMPaC has also developed and evaluated alternative pipeline routes and installation concepts incl. hydraulic and temperature simulations and calculations and emission reports. The detailed design of the Dry Section Pipeline Facilities comprised Pipeline Stress Analyses, Dry Section Layout Optimization and multidisciplinary design and engineering work. IMPaC also developed and prepared the overall operation management system and provided Construction Management and consultancy services for offshore and onshore installation works. In addition IMPaC contributed to the Certification of the Automation System.
