Subsea Processing – Happening Now!

12 – 14 November 2012

Stresa, Italy

Technical Agenda

Monday, 12 November, 0900–1100

Keynote/Plenary Session

To set the scene for the workshop and as an introduction to session I, a keynote/plenary session has been arranged with a panel of recognised senior industry experts from operators and suppliers. The panellists will provide their views on the opportunities and issues associated with implementing subsea processing as part of a field development and increased recovery initiative. A facilitated discussion will encourage questions and comments from participants, which will provide an opportunity to “break the ice” and launch an open and active dialogue for the workshop.


Session I: Concept Development

Session Managers: Rick Kopps and Hans Kristian Sundt

The first hurdle any subsea processing project must pass is the conceptual phase of the field development. This session will look at the role of the concept development phase of major capital projects. What can we learn about this phase from the projects that have succeeded? What arguments are others making to convince management to pursue the option to maximise economic gain with the greatest perceived risk vs. choosing the minimum economic threshold and utilising the “status quo” solution? How do we prevent inappropriate/overly conservative assignment of risk to this technology during the conceptual phase?

Presentations will look back at the “path taken”, the resulting lessons learned from early subsea processing projects and the current state of subsea projects. The discussions will then focus on how we as an industry can work to ensure that more subsea processing projects succeed in the concept development phase.


Session II: Separation and Pumping

Session Managers: Jeff Jones and Jay Swoboda

With a growing number of separation and boosting technologies and installations, it is important to understand the differences in these technologies and the drivers for selecting one over another. Topics include current technologies, evolving needs and the technical drivers and incentives for selecting specific technologies.

The separation portion of this session addresses the leading technologies including current and “state-of-the-art” subsea separator design, process technology and flow assurance considerations. There will also be a section on boosting which covers current pump technologies including developments in subsea pump design and industry-led pump qualification efforts currently underway. Each section of this session will include discussion sessions to cover the various technologies and specific drivers for selecting a specific type of subsea separation and/or pumping system.

Tuesday, 13 November, 0900–1230

Session III: Compression and Power

Session Managers: Simon Davies and Knut Nyborg

Following on from the discussions on separation and pumping in session II, we will first address the need for reliable and cost-effective power supply and distribution in subsea processing. Technology status and needs will be presented and discussed in terms of power requirement and step-out distance, illustrated by examples. This will be followed by a facilitated discussion that will assess the future direction of subsea power.

The second part of the session will focus on subsea compression, which is rapidly emerging as a new business area in subsea processing. Drivers and needs will first be addressed, looking at “where, why and how much” compression can be applied. Following this, the status of the three ongoing subsea compression projects will be explained. Participants will then discuss the future market potential and technology trends related to subsea compression.


Session IV: Design and Operational Considerations

Session Managers: Svein Håheim and Bjørn-André Egerdahl

Subsea processing systems are growing in complexity, with larger scale and more complex systems being designed and deployed. This session is focused on best practices and learnings from present deployments and how these can be applied to ongoing and future projects. Specific topics are installation and intervention challenges, condition monitoring and maintenance, reliability and availability experiences and modelling, testing and technology qualification and standardisation.

Wednesday, 14 November, 0900–1230

Session V: Operating Experience

Session Managers: Per Arne Nilsen and Henning Gruehagen

The last session of the workshop will be unique, as for the first time operators from around the world will address specific subsea processing projects that have been deployed, commissioned and recently started operation. The projects will be briefly presented, together with the main design choices that facilitated a subsea processing solution. The focus of the session will be to address current and future challenges and what we can learn from them. In addition to operational challenges, challenges around intervention, service and repair and interventions strategies will be addressed. Discussions will be encouraged and the session will challenge the audience on how these learnings could help pave the way for even more subsea processing projects in the future.
