Weathering data of Buzzard crude oils – Input to Oil database for OSCAR simulations
(SINTEF Ocean rapporter;OC2024 A-088, Research report, 2024-10-07)A standardized bench-scale weathering study has been performed on two Buzzard crude oils from the main field and the northern terrace manifold (NTM), respectively. The laboratory data of the crude oils are input to the ... -
Weathering study of TOR II and evaluation of oil weathering properties on Eldfisk S and Ekofisk J - In relation to oil spill response and evaluation of the predicted behaviour relative to previous studies of Ekofisk oils - OC2022 A-050
(SINTEF Ocean rapporter;OC2022 A-050, Research report, 2022-05-19)SINTEF Ocean has performed a standardized small-scale weathering study, including dispersibility testing, on TOR II. Limited laboratory studies were conducted for Ekofisk J and Eldfisk S to compare the weathering properties ... -
A Web-Based Communication Tool for Postoperative Follow-up and Pain Assessment at Home After Primary Knee Arthroplasty: Feasibility and Usability Study
(Peer reviewed; Journal article, 2022)Background: We report the use of an electronic tool, Eir (Eir Solutions AS, Norway), for symptom registration at home after knee arthroplasty. This electronic tool was used in a randomized controlled trial (RCT) comparing ... -
A Web-Based Platform for Efficient and Robust Simulation of Aquaculture Systems using Integrated Intelligent Agents
(Peer reviewed; Journal article, 2023)We propose a web-based platform of integrated intelligent agents that incorporates multiple Functional Mock-up Units (FMUs) and surrogate modelling techniques. In this platform, each FMU envelops a stand-alone simulation ... -
