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.

Electrotechnical laboratories

SINTEF Energy Research operates laboratories for high voltage, high power and climatic testing. Customers are manufacturers, suppliers and users of electric power equipment.

Marine Cybernetics Laboratory

The Marine Cybernetics Laboratory is a wave basin, especially suited for tests of marine control systems, due to the relatively small size and advanced instrumentation package. It is also suitable for more specialized hydrodynamic tests (for example forced motion tests), mainly due to the advanced towing carriage, which has capability for precise movement of models in 6 degrees of freedom. Flow measurements can be performed using Particle Image Velocimetry (PIV) technique.

AEMON - Novel Failure Monitoring System for Marine Applications by including Acoustic Emission

22 November 2019

Gear systems are critical in maritime vessels and wind turbines, and damage of components in these systems may lead to catastrophic and costly failure. Today, gears and bearings are often monitored by frequent inspections and manual condition monitoring. However, closed gears are not easily inspected, and in autonomous and remote-controlled vessels and subsea installations, remote condition monitoring is the only option over long periods of time.

HyLINE - Safe Pipelines for Hydrogen Transport

07 November 2019

Hydrogen, the most abundant chemical substance in the universe, may, as an energy carrier hold the key to the inevitable and needed transition from fossil fuels to renewable energy. Together with Norway's important role as a major energy provider in Europe comes the obligation to be a main player in this transition.

Hydrate Management - New understanding of hydrate phenomena in oil systems to enable safe operation within the hydrate zone

09 September 2019

For the O&G industry, risk-based hydrate management can be a viable strategy for significantly widening the operational window. The traditional approach has been to avoid entering the hydrate region (high pressure and low temperature) altogether by temperature control (insulation and heating), chemicals (methanol and glycols) and pressure control. Although ensuring safe operations these remedies are costly for longer and colder transport conditions and not necessarily environmentally sound. This project will help meet demands of marginal field developments by advancing the new fundamental knowledge of gas hydrate properties and develop methods for risk assessment, minimize environmental impact and cost-effective hydrate management.

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.
