Developing invaluable software solutions
Ramboll is constantly developing new software tools for the project to be able to model the complexities of the project and efficiently optimise the design.
Especially a tool for determining fatigue life for free spanning pipeline is being developed. (The tool is developed using ANSYS for Eigen frequency analysis and Mathlab for classification of Eigen frequency, hydrodynamic loading and fatigue calculation).
“The investment made in developing the tools in-house will become extremely valuable for us for future projects as we can activate them on new projects, too. You simply cannot buy the tools in the market. They will become valuable for future projects of similar character enabling fast execution of extensive design disciplines,” says Kristoffer Bergholt, Engineering Manager of the project and Team Leader in the department of subsea and pipelines.
Raising the bar on FEED projects
With the help of the software tools the team was able to deliver a very comprehensive Front-End Engineering Design (FEED) to Statoil.
“Our initial ambition was to make the world’s best FEED. It was matured to be close to detailed design for several disciplines. Statoil was very happy with our work and have highlighted this as how they see FEED for future projects. This of course is a great compliment to our work and also a great motivation. We’re not the only ones in the market with know-how about designing highly complex subsea pipelines of this character, but there are very few of us in the Norwegian market,” says Kristoffer Bergholt.
Statoil: Design will be competitive factor for similar future projects
The pioneering aspects of the project call for high-class expertise and technical understanding of the challenging environment while keeping future expansion opportunities in mind.
Engineering Manager at Statoil A/S, Morten Aamodt, says:
“The key factors for success are to have the necessary technical competences and experience and to have the ability to understand each other’s expectations. And I believe this is the case between Statoil and Ramboll. The pipeline design made by Ramboll so far, and the engineering tools developed for this project to optimise the design will become a competitive factor for similar future projects.”
- The Polarled Pipeline Project comprises a 36", 481 km gas transmission pipeline from the Aasta Hansteen field, located in the Norwegian Sea, to Nyhamna gas facility in the western part of Norway.
- It is expected that a pipeline to the Barents Sea, which would potentially add another 1000 km, is a natural expansion of the Polarled pipeline.
- Ramboll carries out FEED, detailed design, route optimisation, pipeline tie-in, geotechnical foundation design, risk and safety, EIA, interface coordination.
- Project period: 2013 – 2016
- Customer: Statoil
- Budget: NOK 25 billion
