...implementation of the EEDI is based on calm water conditions. Depending on the type and size, vessels are not allowed to exceed a threshold for emitted CO2. However, when vessels operate under real-sea conditions with effects of wind and waves, the emissions are higher than assumed for a given speed according...
...mitigated. However, risk mitigation comes at a cost, and only the countermeasures that cost-efficiently mitigate risks should be implemented. This report presents an approach to integrate the countermeasure cost-benefit assessment into the risk analysis, and to provide decision makers with the necessary decision...
Flow diagnostics are simple quantities that can be derived from basic flow simulations to probe a reservoir model, establish connections and basic volume estimates, and measure heterogeneity in flow paths. This user guide introduces various types of flow diagnostics, followed by an overview of two graphical...
...operators and regulators. The FanSi model formulates optimisation problems in the form of Linear Programming (LP) problems to solve the economic dispatch problem (EDP). We apply the decomposition technique Lagrangian Relaxation (LR) on the EDP with the goal of reducing computation time and obtaining...
...of a system. The PREDIQT method develops and makes use of a multi-layer model structure, called prediction models. Usefulness of the prediction models requires a structured documentation of both the relations between the prediction models and the rationale and assumptions made during the model development...
...of measuring work conditions, and offers suggestions for improving practice. We discuss the needs for updated and representative measurement of working conditions in Norway, and argue that despite Norway’s strong tradition of work life research, studies of work life and working conditions have almost...
Multiscale simulation is a promising approach to facilitate direct simulation of large and complex grid-models for highly heterogeneous petroleum reservoirs. Unlike traditional simulation approaches based on upscaling/downscaling, multiscale methods seek to solve the full flow problem by incorporating...
...are interconnected and in many cases there is still potential for further production improvement by only optimising the different stages (e.g. separate grinding, mill operation etc.). This, in turn, indicates the potential for quality improvers to further optimise the production and improve the quality...
...upon version V1.0 of the ZEN definition guideline and series of ZEN definition reports. The ZEN categories for GHG emissions, energy, and power have been updated after having been tested in selected pilots. In addition, a description of the ZEN KPI tool and framework has been added. Finally, the ZEN categories...

...energy production, and variable energy prices in different industrial com panies to make an optimization entity for industrial cluster energy use. We discuss two energy optimization approaches: a centralized choice for all energy consumption and local-level trading of energy surplus and develop a graph-based...
...state-of-the-art within electrical systems for pumped storage plants. Three main different systems are presented and evaluated: Constant speed, adjustable speed with doubly-fed induction machine and adjustable speed with a full rated frequency converter. Pumped storage hydropower systems have been used for...
...passenger car tyres measured in 2003 and 2004. In 2003 preliminary measurements on 6 tyres on 9 different road surfaces were performed. In 2004, the measurements were done in 2 parts:1) 7 car tyres were measured on two test tracks in the Netherlands: ISO-surface and a two layer porous asphalt (2LPA)2)...
...summarizes the activities and results from the research project "Oil spill containment by use of air bubbles". The goal of the pro;ect has been to investigate how air bubble induced flows can be used as a barrier against oil spills in coastal and environmentally sensitive areas and to prepare for industrial...
...developed at SINTEF, for the efficient joint modelling of active power control and structural degradation due to fatigue damage. It bridges two fields of research that are traditionally split: grid integration and mitigation of asset degradation, through multi-objective wind farm control. Component-level...
...an ongoing process within the EU on how to fulfil the commitment made to the Paris agreement. The role of hydrogen, and in particular hydrogen from natural gas combined with capture and storage of the produced CO2 (CCS), is debated. The hydrogen for Europe pre-study has been undertaken with the purpose...
...products and solutions that will lead to the realization of sustainable neighbourhoods with zero greenhouse gas emissions. These solutions will be tested in the eight real life pilot projects in Norwegian municipalities. When searching for the best solutions, we first need to map the pilot projects and the...
...precise, consistent and understandable vocabulary for our work on model-based user interface development, by finding or making our own definitions of concepts that are central in this field. When working on the definitions, we have exploited general vocabularies for describing and categorizing computer...
Expert judgments are often used to estimate likelihood values in a security risk analysis. These judgments are subjective and their correctness rely on the competence, training, and experience of the experts. Thus, there is a need to validate the correctness of the estimates obtained from expert judgments...
Relaxation and Benders decomposition, were studied. The computational experiments showed that results were not of high enough quality to be used with the FanSi model. Benders decomposition was applied for decomposition in time. Three decomposition schemes were tested, one serial implementation and two schemes...
