Subsea is the next frontier, and an important research area for SINTEF

At SINTEF we have a strong research teams on subsea power and power electronics, which provide customers with more secure, robust and efficient subsea solutions. We have laboratories, equipment and expertise to test and develop materials and components for demanding environments, and in deep water and high and low temperatures.

Expertise

CFD - Computational Fluid Dynamics

The CFD group at SINTEF Energy Research has more than 30 years of experience in performing numerical modelling of chemically reactive processes in laminar and turbulent flows consisting of single-phase (gaseous fuels combustion) or multi-phase (solid fuels combustion) configurations. Depending on the specific needs and time constraints of our customers, we are able to perform numerical simulations that boast a wide range of accuracies, geometric complexity and computational cost.

Direct Electric Heating of pipelines (DEH)

Hydrate and wax formation in subsea transport flowlines will cause undesired fluid properties and even blocking of the wellstream, following shutdown and comprehensive repairs. Direct electrical heating (DEH) is developed at SINTEF Energy Research and qualified as a method for avoiding hydrates and wax, and is also applicable for removal of plugs.

Electrical insulation systems and electrical insulation materials

High reliability of the electrical insulation system is of key importance to any high voltage apparatus. The effect of many parameters/mechanisms needs to be carefully assessed when designing electrical insulation systems. In particular the effect of humidity, temperature, pollution/contaminants, mechanical and electrical stress, and external pressure need to be assessed in order to assure high reliability of the insulation system.

Power Electronics

The conversion of electric power by means of power electronics (converters) is playing an increasingly important role in various parts of the power system. Examples include the integration of renewable power plants, high-voltage direct current (HVDC) transmission and electrification of the oil and gas sector.

Power electronics for subsea applications

Deep-water subsea oil production installations require complex electrical power systems. There is currently a need for local supply systems close to wellheads serving equipment such as gas boosters, oil pumps and separators. In the future we anticipate the development of supply systems for long step-outs where high voltage DC represents a viable solution.

Subsea - Offshore Power Supply

The costs for repair and maintenance of high voltage equipment installed in deep waters can be very high. Therefore, high operating reliability is crucial for the components placed at the seabed. At high hydrostatic pressures, water ingress is the most challenging for the electrical insulations systems and materials used in power supply components. Due to environmental issues the equipment positioned at remote distances from land must be supplied by using subsea power cables. In many cases this calls for developments of new technologies, such as pressure compensated high voltage components.

Transformers

A power transformer is a complex apparatus with windings, core, tap-changer, bushings etc., designed and manufactured for many years of operation in a power system. SINTEF has know-how and runs projects in the transformer technology field; spanning from development and testing of materials for manufacturers, ageing performance, condition monitoring and life estimation, to analysis of interaction between power systems and transformers. A big challenge for the utilities is asset management of ageing transformer fleets.
