Risk assessment using Hybrid Causal Logic (HCL) modelling - Assessing the collision risk of an unmanned autonomous vessel
(Master thesis, 2021)Autonome skip utvikles for tiden for bruk i offentlige farvann. Et av kravene til autonome skip er at de skal være minst like sikre som konvensjonelle skip. For å oppnå dette er effektiv samhandling og kommunikasjon mellom ... -
Risk assessments in the Norwegian aquaculture industry: Status and improved practice
(Journal article; Peer reviewed, 2018)The Norwegian aquaculture industry has the potential to become the country’s leading ocean industry in the future. More than 99% of the produced biomass is Atlantic salmon and trout. Norwegian fish farming is characterised ... -
Risk Aware Control of Underwater Snake Robots in Confined Environments
(Master thesis, 2023)The growing interest in ocean discovery imposes a need for inspection and intervention in confined and demanding environments. To tackle these demanding environments, articulated underwater robots, such as Eely, with their ... -
Risk Based Maintenance for Compressor Systems
(Master thesis, 2015)This thesis reviewed part of the maintenance activities in a compressor system using the risk based maintenance philosophy. The goal was to verify if a contribution could be made to the maintenance plan of the system. The ... -
Risk dimensions of fish farming operations and conflicting objectives
(Chapter, 2018)Operations at sea-based fish farms can be challenging, and several risk dimensions are of concern during operations. Sea lice represent a challenge for the fish farmers who are required to perform delousing when the ... -
Risk from cyberattacks on autonomous ships
(Chapter, 2018)The vulnerability of technological and administrative systems to cyberattacks has been shown to be high in several cases, which has led to different unwanted consequences. Autonomous ships will also be exposed to the threat ... -
Risk identification of third-party damage on oil and gas pipelines through the Bayesian network
(Journal article, 2018)This paper aims to identify the risks influencing oil and gas (O&G) pipeline safety caused by third-party damage (TPD). After comprehensive literature study, we found that the traditional risk identification of TPD suffers ... -
Risk in context to autonomous vessels in transit
(Master thesis, 2021)Det overordnede temaet for denne oppgaven er risikoen som blir introdusert når autonome systemer tas i bruk. Oppgaven gir en grundig forklaring til bakgrunnen innen feltet og utviklingen gjennom årene. Oppgaven illustrerer ... -
Risk in crane and lifting operations related to the logistic interaction process for well and drilling
(Master thesis, 2011)This master thesis compares the logistic chain of operations and maintenance versus drilling and well and finds how drilling and well affect this chain with regards to risk on crane and lifting operations. Research has ... -
Risk influence frameworks for activity-related risk analysis during operation: A literature review
(Journal article, 2017)Experience gained in the petroleum activities have showed that major accident risk is inherent in daily activities. Risk influence methodology is perceived as a good candidate to model the activity-related risk, as a key ... -
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 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 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 ...
