A weathering study has been conducted on Aasta Hansteen blend condensate. The study is based on a small-scale laboratory testing at 13 °C. The SINTEF Oil Weathering Model (OWM) was used to predict the weathering properties of the Aasta Hansteen blend condensate if spilled on the sea surface. The...

...project adapts the use of autonomous and tetherless underwater vehicles as a carrier of sensor systems for data acquisition, where the data are transferred from sea-based fish cages to a centralized land base (Figure 1). The vehicle will use active motion con-trol and acquire data from the cage environment...

...by SINTEF Fisheries and Aquaculture demonstrates an approach with the potential to increase the efficiency of oil spill recovery operations, in particular by concentrating the surface emulsion layer and reducing the leakage under oil booms, but also by recovering dispersed oil and underwater spills at...

...heating and heat pumps for reduced power consumption The Norwegian power system is facing enormous challenges in the transition to a fossil-free society. The on-going electrification of transport and industry, together with establishment of new power-intensive industries, calls for rapid and extensive...

...memo describes the development process of simulation and optimization models for energy-flexible operation of building envelopes. These models consist of linear time invariant state space models designed to consider space heating qsh as the input and the following inputs as disturbances: outdoor temperature...

Fluorescence (XRF) to identify objects containing Indium and other critical material on-line in a waste stream a series of tests were performed on e.g. mobile screen and batteries. Due to the extensive time needed to record the full XRF spectrum of each item and of reference samples of the critical elements to...

The objective of this state-of-the-art report (STAR) is to review work done to make pozzolana from natural occurring minerals by chemical treatment, and also outline principle possibilities of doing so. It does not include pozzolana by thermal treatment as for e.g. clays. Based on the theory of acidity...

The result of activity 1 Acoustic element design studies. Assessment and analyzes of different possible design” in the subproject 5.2 is reported here. The main goal of the subproject 5.2 is to find possible acoustic solutions for effective use of passive thermal mass (ptm). The acoustic element design...

Almost every household in Norway has a smart electricity meter installed. The advanced functionality of the meters and the large amounts of data transmitted from them have the potential to contribute to more than just a more accurate billing of customers. This report is a result from the ENERGYTICS...

...prosjektet var å utvikle, prøve ut og evaluere en ny opplæringsmodell for trafikkopplæring på sykkel basert på det vitenskapelige konseptet Mind, Bra in and Education (MBE), som utnytter samspillet mellom nevrovitenskap, psykologi og pedagogikk. Opplæringsmodellen er forankret i kunnskap om hjernens utvikling...

...over condition monitoring (CM) and structural health monitoring (SHM) for offshore wind turbines with a special focus on two innovative sensor types – Fiber Bragg Grating (FBG) and Microelectromechnical Systems (MEMS) sensors. Based on a limited literature survey and interviews with wind turbine operators...

The objective of the CruiZE project is to develop innovative, integrated and environment-friendly concepts for supplying heating and cooling needs for the hotel facilities on board cruise ships. As in other sectors, there are non-technological barriers which must be addressed to pave the way for...

...on SMA surfaces exposed to winter conditions and studded tyres. The correlation is improved if the ISO-levels are compared to surfaces not exposed to winter conditions. A 1/3rd octave band frequency analysis have been performed on all CPX-measurements, and compared with SPERoN modelling results. The analysis...

This report presents the open INO OptiFLEX 22MW floating wind turbine design, used as a case study in the OptiFLEX project....

...of the oil components. Samples collected in 2023 from both the oiled area and a nearby reference area have now been subjected to chemical and microbial analyses to characterize the long-term natural (bio)degradation of oil and the microbial community composition in a non-treated experimental oil spill...
