Subsea Pipelines & Cables


Subsea Pipelines & Cables


11 – 12 October 2022 in Trondheim

– Previously known as “Offshore Pipeline & Risers” –

Conference language: English

NPF is pleased to invite the pipeline, riser, umbilical and power cable community to Trondheim for the traditional two-day conference, 11-12 October 2022. Being a post-covid event, we hope that the conference will again be a popular networking forum where recent achievements, case studies, industry trends and new developments are discussed and presented.

To better reflect on market trends, the Program Committee have decided to change the conference title to Subsea Pipelines & Cables. The conference format will address topics related to design, installation, operation and new technology solutions. As always, this conference will include technical and field-specific presentations as well as good time for networking. There will also be strong focus on future developments with a national and international perspective.


Abstract DEADLINE is now closed. 

We have received many abstracts of high quality.  Thanks to everyone that have submitted an abstract. After thorough consideration the committee has now chosen who will present at our conference, and we are very pleased to see such a wide variety in the difference companies presenting this year.

The programme is now published under the tab “Program” and the conference is now ready for registration.

On behalf of the Program Committee, we look forward seeing you in Trondheim in October!

END of conference day 2

Mark Christian Degn Eskesen

Engineering & Asset Manager, Energinet

In my recent working career, I have designed large onshore and offshore energy infrastructure, advised authorities and companies on the transitional path to a sustainable energy future and performed various techno-economic studies, including CAPEX, OPEX and ABEX estimates.

Currently, I am working for Energinet on the Baltic Pipe Project, which includes technical project responsible for the 105 km Baltic Pipe offshore pipeline construction and installation, landfall construction works as well as commissioning. The Baltic Pipe project connects the Norwegian gas grid with the Danish and Polish transmission systems via the EPII pipeline in the North Sea. Responsible for detailed design, procurement of line pipes, construction and installation works as well as commissioning activities. This includes developing ITT material and managing the technical part of the tendering process to secure the settlement of contracts with main contractors (Allseas and DeepOcean). Managing the engineering project team as well as internal and external stakeholders, including authorities and permitting processes to ensure high quality deliverables on time. Construction activities have taken place in 2021 and commissioning and first gas in 2022.
