Efficient operations using numerical methods
Marine operations performed by offshore vessels become increasingly challenging. In order to avoid most unfavourable situations, one needs accurate and reliable data regarding behaviour of propulsors under realistic operation conditions. Computational Fluid Dynamics can be used to study the hydrodynamic performance of different type of propulsors including azimuth thrusters and tunnel thrusters. The impact of cavitation on tunnel propellers is also addressed. The studies illustrate the importance of dynamic effects associated with propulsor motions, unsteady inflow on propulsor, and interaction phenomena

Our maritime energy systems laboratory is unique in its capabilities as a research facility. We offer a system architecture that will accommodate any power system or component on ships, with the ability to build complex hybrid systems.
The main activities in the laboratory for marine structures are the testing of structures, structural components and materials. Typical problems involve fatigue testing, ultimate strength and collapse testing. Experimental work is often combined with...
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...
The main activity of the towing tanks is related to investigation of hydrodynamic performance of ships. This includes resistance, propulsion, seakeeping in head and following seas, and directional stability tests with free running models. The tanks...
The cavitation tunnel is used to investigate the hydrodynamic performance of different type of ship hulls, propulsors and other hydrodynamic objects. Propeller induced pressure fluctuations and noise as well as cavitation are investigated by means of...
The Ocean Basin Laboratory is used for basic as well as applied research on marine structures and operations. A total environmental simulation including wind, waves and current offers a unique possibility for testing of models in realistic conditions...
SINTEF has designed and manufactured the test rig that mainly will be used for full scale vortex-induced vibrations (VIV) testing of risers and other type of cylindrical structures.
Solving engineering challenges in global response analysis of subsea pipelines, umbilicals and power cables.
In order to improve reliability related to operation of flexible risers there is need for cooperation, improvements and systematic work. The starting point should be an industry consensus of what is the current status and secondly promote and obtain...
Real-Time Hybrid Model Testing is the science of combining advanced simulations, state-of-the-art experimental methods with active control system into a novel approach, to verify the safety and efficiency of marine structures and operations.
Important work on the validation of shiphandling manoeuvring models is being conducted in the R&D project SimVal (“Sea Trials and Model Tests for Validation of Shiphandling Simulation Models”, founded by the Research Council of Norway).
Helicopter manufacturer AgustaWestland has been carrying out model tests in our ship-model tank in order to study emergency landings on water and helicopters’ subsequent seaworthiness. Very few test facilities anywhere in the world perform tests of...
As an R&D partner in NOWITECH (Norwegian Research Centre for Offshore Wind Technology), SINTEF Ocean have been actively involved in developing robust numerical tools for the design and modelling of bottom-fixed offshore wind turbines.
The European Union project MUNIN (Maritime Unmanned Navigation through intelligence in Networks) is studying the possibilities of realising a completely unmanned ship by looking at the need for new sensor systems, improved maintenance methods...
SINTEF is involved in projects concerning novel concepts and innovative solutions for ocean energy, such as DeepWind and FAROFF, supported by the European Union and the Research Council of Norway.
In collaboration with Statoil and TNO - Netherlands, SINTEF has developed and validated a novel methodology for determining the operational limits of free-fall lifeboats.
Much of Norway's production of crude oil is transported by ship. Particularly during loading, volatile organic compounds (VOCs) are released from the ship's cargo tanks to the atmosphere.
