Ocean space Subsea
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.
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.
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.
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.
Cooling is a crucial aspect of electronics design, all the way from high-power industrial applications to personal computers. We investigate and develop ways of creating more efficient and reliable cooling systems, using magnetic nanofluids (ferrofluids).
Numerical modelling of environmental processes supports objective, science-based management of natural resources as well as recreational and industrial activities. SINTEF is in the forefront in developing models addressing effects and risks associated with operational and accidental discharges to the environment.
At the SINTEF Multiphase Flow Laboratory, more than two decades of operational and scientific experience are united in working with multiphase flow phenomena.
The Offshore Structures group has long experience and internationally recognised expertise in both theoretical and experimental hydrodynamics. Much of our activity is based on MARINTEK’s hydrodynamic laboratories, but we also possess world-leading expertise in computational fluid dynamics (CFD) and numerical hydrodynamics.
We have extensive experience with developing and executing projects related to oil/gas/water separation relevant for electrocoalescence separation, the liquefaction processes of natural gas, and developing potential studies related to subsea technology. Our services assist the industry in providing detailed experiments and models in order to optimize the construction and operation of equipment with respect to efficiency and costs. Our partners include research institutions and industry, both in Norway and abroad.
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.
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.
SINTEF’s multi-technology basis has made flow assurance a key subject in many technological areas. Together with our industry partners we develop break-through technology solutions for the production and processing industries, including the oil production, metallurgical, hydrocarbon processing, chemical and petrochemical industries.
In the field of process technology, we are currently working with theoretical analysis, modelling and simulation, combined with experimental approaches to the analysis, design and optimisation of industrial gas processes and efficient energy conversion systems. We are focusing on both open and cyclic processes – right down to single component level.
Self-healing electrical insulation materials for high voltage apparatuses are very attractive, especially for new and high-power demand applications when placed in locations which are difficult to access and in harsh environments. Applications include offshore wind farms, subsea grid and equipment located in the Arctic.
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.
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.
SINTEF Energy Research operates laboratories for high voltage, high power and climatic testing. Customers are manufacturers, suppliers and users of electric power equipment.
LORCENIS – Long Lasting Reinforced Concrete for Energy Infrastructure under Severe Operating Conditions
The main goal of the LORCENIS project is to develop long lasting reinforced concrete for energy infrastructures under extreme operating conditions.
FerroCool is an experimental project that will investigate ferrofluid heat transfer. It is an early step towards realizing a novel, efficient and reliable cooling concept that uses magnetic nanofluids.

Aquaculture industry needs innovative thinking
Industry, biologists and engineers will need to cooperate more closely if Norway is to maintain its position as a leading marine nation.
More efficient marine operations
The Research Council of Norway has awarded MARINTEK NOK 5.5 million to participate in a research project that aims to develop decision-making simulation software for marine lifting operations.
Taking care of elderly wells
Thousands of old offshore oil wells will have to be plugged to prevent them leaking. The process may cost several hundred million Norwegian kroner, and you and I will have to find most of the money. Researchers are now proposing a solution that may offer some relief for what is a major headache for the Norwegian state.
