Risk-based Convolutional Perception Models for Collision Avoidance in Autonomous Marine Surface Vessels using Deep Reinforcement Learning
(Chapter, 2023)In this work, we propose a novel policy network architecture for model-free Reinforcement Learning (RL)-based path-following and collision avoidance in marine surface vessels. By applying convolutional neural networks ... -
Risk-based decision-making support model for offshore dynamic positioning operations
(Journal article; Peer reviewed, 2021)A Dynamic Positioning (DP) system enables vessels and rigs to accurately maintain a predetermined position and heading or track. It enables precise operations under harsh environmental conditions. DP is used for a variety ... -
Risk-based Design of an Offshore Wind Turbine using VoI Analysis
(Chapter, 2019)Monopiles are the most common solution for supporting wind turbines in offshore conditions. At the design phase of a monopile, a frequency check is to be performed to avoid the resonance hazard with the 1P and 3P excitation, ... -
Risk-based Fatigue Design Considering Inspections and Maintenance
(Peer reviewed; Journal article, 2020)The different phases of a structure’s life-cycle are managed by different teams with little interaction. Correspondingly, the optimization of the individual phases is isolated and does not necessarily result in optimal ... -
Risk-based implementation of COLREGs for autonomous surface vehicles using deep reinforcement learning
(Peer reviewed; Journal article, 2022)Autonomous systems are becoming ubiquitous and gaining momentum within the marine sector. Since the electrification of transport is happening simultaneously, autonomous marine vessels can reduce environmental impact, lower ... -
Risk-based inspection planning for hydrogen technologies: review of currents standards and suggestions for modification
(Journal article; Peer reviewed, 2021)The research addressing loss of integrity (LOI) for hydrogen containment technologies requires a multidisciplinary perspective. However, lack of collaboration between materials and process safety engineers is reflected in ... -
Risk-based maintenance backlog
(Chapter, 2018)A relevant issue in manufacturing and production seems to be “silo”-organisations and “silo”-planning with lack of coordination between departments. Integrated Planning (IPL) is a concept that aims to cope with this ... -
Risk-based management framework for microplastics in aquatic ecosystems
(Peer reviewed; Journal article, 2022)Microplastic particles (MPs) are ubiquitous across a wide range of aquatic habitats but determining an appropriate level of risk management is hindered by a poor understanding of environmental risk. Here, we introduce a ... -
Risk-Based Model Predictive Control for Autonomous Ship Emergency Management
(Peer reviewed; Journal article, 2020)Control for semi- and fully-autonomous ships is a broad and complex field. Making autonomous high-level decisions in place of the captain is considered difficult, partly due to the risks and uncertainties involved. Though ... -
Risk-Based Obstacle Avoidance in Unknown Environments using Scenario-Based Predictive Control for an Inspection Drone Equipped with Range Finding Sensors
(Chapter, 2019)This paper develops an obstacle avoidance strategy for inspection drones equipped with simple range finding sensors, such as radar or sonar. The obstacle avoidance strategy uses scenario-based model predictive control where ... -
Risk-based supervisory control for autonomous ship navigation
(Peer reviewed; Journal article, 2023)This paper proposes a novel method to transform the results of qualitative risk analysis into a numeric optimal control problem for autonomous ship navigation. Today, making autonomous high-level decisions replacing a crew ... -
Risk-benefit assessment of five underutilized fish species in Norway
(Peer reviewed; Journal article, 2023)Risks and benefits of increasing the consumption of five underutilized demersal fish species in Norway by applying the Benefit-Risk Analysis for Foods (BRAFO)-tiered approach were assessed. A reference scenario with zero ... -
Risk-informed control systems for improved operational performance and decision-making
(Peer reviewed; Journal article, 2021)Autonomous systems, including airborne, land-based, marine, and underwater vehicles, are increasingly present in the world. One important aspect of autonomy is the capability to process information and to make independent ... -
Risk-related information needed through the planning process for offshore activities
(Journal article; Peer reviewed, 2018)Planning and plan quality influence safe and efficient execution of work in offshore oil and gas activities. An important basis for developing good plans and making good decisions during the planning process is to have the ... -
Risk-taking behavior of adolescents and young adults born preterm
(Peer reviewed; Journal article, 2023)Objectives To study sexually transmitted Chlamydia trachomatis infections (STCTs), teenage pregnancies, and payment defaults in individuals born preterm as proxies for engaging in risk-taking behavior. Study design Our ... -
RiskBIM - Risikostyring i BIM-drevne offentlige samferdselsprosjekter
(IFE/E;, Research report, 2022)This report summarizes the main results from the RiskBIM project (Risk management for BIM-driven public transport projects) supported by the Norwegian Research Council. RiskBIM dealt with the use of digital models and BIM ... -
Risks to Norwegian plant health posed by import of plants with soil or other growing media from Europe
(Research report, 2024)Background: The Norwegian Environment Agency (Miljødirektoratet) and the Norwegian Food Safety Authority (Mattilsynet) tasked the Norwegian Scientific Committee for Food and Environment (Vitenskapskomiteen for mat og miljø, ... -
Risky Play and Children’s Well-Being, Involvement and Physical Activity
(Peer reviewed; Journal article, 2021)Children’s activities and experiences in Early Childhood Education and Care (ECEC) institutions are essential for children’s present and future lives. Playing is a vital activity in childhood, and playing is found to be ... -
Risky play in children’s emotion regulation, social functioning, and physical health: an evolutionary approach
(Journal article; Peer reviewed, 2022)The focus of this theoretical paper is to explore three biopsychosocial levels of children’s risky play: (1) mental health and emotion regulation, (2) social functioning and challenging norms, and (3) physical health and ...
