1 Mapping Scientific Needs in the Arctic and Northern Areas Subsea Power Technology A key factor in order to unlock the Artcic in a sustainable manner Brussels, 11 Henrik Steine Madsen Head of Siemens Subsea Systems Siemens AG All rights reserved

2 The age of easy oil is over! New oil fields are located further offshore and in harsh environments Challenge With current field-proven technology, many remote hydrocarbon fields cannot be developed. Solution Siemens takes on the challenge and will provide the Subsea Power Grid to enable remote subsea development and processing.

3 The Power Grid will be an integral part of the Subsea Factory, enabling subsea processing «We are taking subsea longer, deeper and colder. Through innovative thinking and collaboration with partners, we aim to develop the elements required for a subsea factory by Statoil» Deeper waters, complex reservoirs, harsh fluids Longer subsea step-outs (distance from well to process facility) Drive for increased recovery from existing fields Reduce costs to drive marginal developments Source: E O Subsea

4 Unlocking the Arctic resources Siemens Subsea Power Grid Provide the infrastructure for energy and communication. Local energy supply at the seafloor. Enable processing of the fluids and transport to beach.

5 The Siemens Subsea Power Grid km

6 Longer transmission lengths! Coastline 200 km 600 km Combination of transmission length and power requirement drives for new technology solutions Technology selection i discussion AC vs Low Frequency AC vs DC How far can we reach with AC Effects of compensation Low frequency AC DC challenges Current solutions are based on AC and compensation. * Illustration courtesy of Statoil

7 Reliable distribution of power subsea Higher number of subsea loads Industrial switching technology High power connectors

8 Pressure tolerant power electronics Subsea VSD First application - Variable Speed Drive (VSD) Oil filled and cooled by natural convection Components can be applied for various applications Development of pressure tolerant power electronics is a gamechanging step!

9 Remote Control & Monitoring Control of dynamic processes over long distances Monitoring and health status of equipment Early detection and isolation of failures Subsea Powergrid can provide the infrastructure for Subsea Surveillance Systems Asset integrity Environmental monitoring Reservoir integrity

10 Environmental monitoring In order to manage it, you have to measure it Surveillance of pre-activity baseline Surveillance during operations Surveillance after decommissioning

11 Permanent reservoir monitoring Surveillance of the reservoir integrity. Provide time lapse data Microseismic activity Automatic fault detection From towed to seabed and from rarely to continuous.

12 Can we develop technology that can unlock the Arctic in line with our values? Our values Responsible Committed to ethical and responsible actions Excellent Achieving high performance and excellent results Innovative Being innovative to create sustainable value In Siemens we believe so and we will play a part in making this happen in a sustainable manner every day!
