Future challenges are mainly related to three specific scenarios:

• Utilization of existing infrastructure and tail production
• Development of new and remote areas with no or little infrastructure
• Specific arctic requirements

Additional issues, which are common to all developments and operations, will be even stricter environmental requirements and continued focus on reliability, safety and cost.

All these challenges have one thing in common: the need for reliable power supply to subsea installations. The ability to supply enough and stable power to subsea installations as the power need is growing, the depths are getting larger and the step out distances are getting longer, is in itself a challenge that must be overcome. This is acknowledged by the strategic forum OG21, which has pinpointed subsea power supply as one of the areas where fundamental research is needed.

The Research Council of Norway (RCN), through Petromaks, has awarded funding for three large competence building projects in the area of subsea power supply to SINTEF Energy Research. A large consortium of industry partners is also involved in the projects. The three projects cover more or less the total power supply chain from production site (platform/floater or shore) to the consumer (motor drives, pumps, compressors etc.) The titles of the three projects are:

• Electric Power Systems for Remote and Deepwater Processing and Transportation of Oil and Gas
• Feasible Power Electronics for Demanding Deepwater Applications
• Electrical Insulation Materials and Insulation Systems for Subsea High Voltage Power Equipment

These three projects will have competence building and education of new experts as its main objective. The expected outcome is the fundamental knowledge needed to develop good system solutions for transmission and distribution of electric power to the subsea installations, to design and manufacture the necessary components needed for these systems, and to test and qualify the solutions. 

The projects will be run as three separate projects under a common umbrella. This is accomplished by having separate project managers/project teams and separate steering committees, but common workshops with presentation and discussion of results. The duration of the projects is five years, and the total budget is approximately 70 million NOK during this period.

SINTEF Energy Research will be the lead executing partner in the projects and the partner that has contact with the RCN, but SINTEF ICT and SINTEF Materials and chemistry will also contribute to the execution of the projects. The Norwegian University of Science and Technology (NTNU) will contribute through education of PhDs within the projects.
