The Åsgard Subsea Compression is a high capacity system, designed for large flow rates and pressurernratios. The project has worked towards high ambitions of reliable, efficient and flexible operation. ThernÅsgard Subsea Compression is a platform: To a large degree, the subsea compressor station extendsrntowards the capacity and flexibility of a conventional topside compressor platform. More importantly, itrnprovides a technology and experience platform for both more advanced and broader applications, yet alsornsimpler and leaner solutions.rnThis paper dives into the trial and tribulations from concept to detailed design, fabrication and testing.rnAll were executed within the framework of one contract in an EPC execution framework. Examples willrnhighlight critical activities, both anticipated challenges and issues not foreseen at the outset of the project.rnLack of flexibility in future modification is a general objection to the subsea factory. The Åsgardrncompressor station has a long operational life and the production profile varies significantly throughoutrnthe whole life cycle. The paper will discuss how future functionality can be included in initial design or,rnif best suited, provisioned for future stages.rnTechnology qualifications have been handled with the rigor and timing required in established industryrnpractises. However, in an EPC execution framework, even smaller u0002first ofu0002 engineering or -designs willrndisturb the project’s pace; eventually demanding u0002out of sequence worku0002 to recover quality and progress.rnThe paper presents some u0002first-of’su0002 and discusses the dependency towards the EPC execution framework.rnThis also includes external interfaces and main procurement activities.rnThe compressor station is inherently more multidiscipline than a conventional subsea delivery. Onerncould say that it represents a u0002platform on the seabedu0002 in terms of process functionality. Thereforernengineering tools, methodology and expertise from topside projects has been utilised in the work. Thernexperience harvested by use of integrated systems for schematics, 3D modelling and engineering registersrnwill be summarized and concluded.rnFinally, the organisation set-up and development for the various project phases will be discussed, inrnparticular with respect to follow-up towards main procurement activities, fabrication, manufacturing,rncompletion/testing and commissioning support.
