Risk information for operational decision making in oil and gas operations
(Chapter, 2015)In the oil and gas industry in Norway, there is a strong emphasis on the use of results from risk assessment as input to decision making. Quantitative Risk Analysis (QRA) is extensively used to develop safe design and ... -
Risk information for operational decision-making in the offshore oil and gas industry
(Journal article, 2016)Operational planning decisions, which are characterized by relatively short time lag between decision and implementation, have received little attention in risk and safety research in offshore oil and gas industry. The ... -
Risk information in decision-making: definitions, requirements and various functions
(Peer reviewed; Journal article, 2021)Inappropriate decisions are often regarded as causes of major accidents in the process industries. To improve the quality of decisions, it is important to make the right information available at the right time. The objective ... -
Risk Management in Procurement of Blue-Green Roofs – A Project Owner Perspective
(Journal article; Peer reviewed, 2019)Blue-green roofs are vegetated roofs used for stormwater management purposes. With the roof serving several different purposes at the same time, the risk that any of its functions could be compromised needs to be addressed. ... -

(Chapter, 2019)Blue-green roofs are vegetated roofs used for stormwater management purposes. With the roof serving several different purposes at the same time, the risk that any of its functions could be compromised needs to be addressed. ... -
Risk Management in Shipbuilding Projects - Using Monte Carlo Simulation for Scheduling
(Master thesis, 2014)The main objective of this thesis was to identify potential improvements of the risk management process to DNV GL so that it is best fit at identifying risk of time overruns and estimating project duration. Focus was placed ... -
Risk management of autonomous marine systems and operations
(Chapter; Peer reviewed, 2017)Autonomous systems may lead to smarter and more efficient operations, but emerging risks are involved, because of lack of knowledge and operational experience with such systems, and challenges related to verification of ... -
Risk Model applied to Non-operational Hydrocarbon Leaks on Offshore Installations - Causal modeling of hydrocarbon leaks caused by technical degradation and design error with the use of risk-influencing factors
(Master thesis, 2015)This project proposes a risk model for identifying causal factors of hydrocarbon (HC) leaks on offshore installations and estimating the platform-specific frequency of HC leaks. The central concern is non-operational leaks ... -
Risk modeling of autonomous underwater vehicle operation focusing on the human operator
(Chapter, 2015)Autonomous Underwater Vehicles (AUVs) are used in scientific, commercial and military organizations to conduct surveys and follow a preprogrammed mission path through the oceans. If a fault or an unexpected deviation from ... -
Risk Modeling of DP Operation for Offshore Tandem Offloading
(Master thesis, 2016)The paper proposes a risk model to warn shuttle tanker drive-off previously and detect it punctually, and proposes a risk decision support model to generate, evaluate and select a best vessel maneuvering plan to avoid the ... -
Risk modelling of collision between supply ships and oil- and gas installations
(Master thesis, 2014)This thesis is a framework for risk influence modelling of supply vessel-platform collisions, with the inclusion of central concepts from the Risk OMT model. The framework is a improvement from existing QRA frameworks in ... -
Risk Modelling of Collisions between Passing Vessels and Fish Farm Facilities - A Development of a Frequency Model
(Master thesis, 2018)The aim of this master's thesis is to develop a model that is tailored to estimate the frequency of a collision between a powered passing vessel and a fish farm facility. The aquaculture industry is expected to grow, which ... -
Risk of collision between service vessels and offshore wind turbines
(Journal article; Peer reviewed, 2013)Offshore wind farms are growing in size and are situated farther and farther away from shore. The demand for service visits to transfer personnel and equipment to the wind turbines is increasing, and safe operation of the ... -
The risk of individual fish being captured multiple times in a catch and release fishery
(Peer reviewed; Journal article, 2019)The proportion of angled Atlantic salmon Salmo salar L. being caught and released has increased. If individuals are repeatedly captured, this may have fish welfare consequences. Of 995 Atlantic salmon tagged during catch ... -
Risk Reduction for Floating Offshore Installations Through Barrier Management
(Chapter; Peer reviewed, 2015)Marine system accidents have a relatively high frequency worldwide. In Norwegian waters loss of installations has been avoided the last 20 years, but several near-misses and severe incidents confirm that the risk level is ... -
Risk Reduction Framework for Blue-Green Roofs
(Peer reviewed; Journal article, 2021)As climate change in the Nordic region brings an increase in extreme precipitation events, blue-green roofs have emerged as a solution for stormwater management, hereafter referred to as “blue-green roofs”. The addition ... -
A Risk-Based Approach in Rehabilitation of Water Distribution Networks
(Peer reviewed; Journal article, 2022)A risk-based approach to support water utilities in terms of defining pipe rehabilitation priorities is presented. In a risk analysis in the risk management process, the probability that a given event will happen and the ... -
Risk-Based Control of Autonomous Surface Ship
(Doctoral theses at NTNU;2024:174, Doctoral thesis, 2024)The last few decades have seen tremendous technological development in the maritime industry. Improvements in navigation systems such as Global Navigation Satellite Systems have reduced measurement error and uncertainty ... -
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 ... -
