Human Factors Analysis of Operational Activities
(Master thesis, 2016)Investigation of major accidents shows that along with technical factors, human factors can influence operational activities as well. In spite of this, existing quantitative risk analysis are utilized broadly for technical ... -
Human Reliability Analysis for Dynamic Risk Assessment: a case of ammonia production plant
(Master thesis, 2018)Human and organizational factors play a key role for the prevention and mitigation of major accidents. Risk assessment techniques, as the classical Quantitative Risk Analysis (QRA), are only focused on the analysis of ... -
Hybrid Modelling for Dynamic Reliability Assessments in Subsea Oil and Gas Processing Systems
(Master thesis, 2017)Traditional reliability methods such as fault tree analysis and reliability block diagrams were not designed to account for the complex dynamic behavior of most industrial systems. These traditional reliability methods ... -
Hybrid Prognostic Model for Residual Useful Life Estimation of Degraded Equipment
(Master thesis, 2015)As the consequence of the more widely used complex systems, there has been a shift in maintenance strategy. The traditional corrective maintenance is gradually replaced by preventive maintenance or even more advanced ... -
Impact of partial and imperfect testing on reliability assessment of safety instrumented systems - Possible approaches for inclusion of its effects in reliability assessments
(Master thesis, 2015)Testing of safety instrumented systems is vital to ensure they are able to perform the required safety function when the need arises. These tests are carried out at specified time intervals. The verification of the ability ... -
Implementing IEC 61508 for Qualification of Safety-Instrumented Systems for Submergible Tube Bridges
(Master thesis, 2016)Qualification of new technology (or systems) has become an important discipline within application areas that have strict requirements to safety and/or reliability, and where new technology is not adequately covered by ... -
Industry 4.0 and Predictive Maintenance in a Steam Turbine
(Master thesis, 2018)The current project is structured as follows: first, a brief description of the three industrial revolutions that has occurred in the past years. Then, the introduction and thorough description of the fourth industrial ... -
Joint Maintenance Interval and Spare Parts Optimization using a Discrete-Event Simulation Model
(Master thesis, 2015)The goal of this report is to use discrete-event simulation (DES) as a method for optimizing maintenance strategies, such as spare parts levels and maintenance intervals. Firstly, the au- thor argues for spare parts ... -
Maintenance Excellence
(Master thesis, 2018)The concept of maintenance has been evolving in the industry through the years. Maintenance passed from been a necessary evil to a concept where organisations can generate value through maintenance activities. Implementing ... -
MAINTENANCE STRATEGIES IN CIVIL ENGINEERING - OVERVIEW AND APPLICATION IN FERRY FREE E39
(Master thesis, 2016)This report focuses on the maintenance activities in civil engineering considering the used case Bjørnafjorden as a part of Ferry Free E39 project. Civil engineering is one of the oldest sectors in engineering, and its ... -
Methodology for Identification of Dangerous Combinations of Output States of SIS
(Master thesis, 2015)Many operations in process industry and other application sectors involve inherent risk due to different hazards. A safety-instrumented system (SIS) is installed to prevent development of a hazard to an accident or to ... -
Model Uncertainty Analysis in Operational Risk Analysis
(Master thesis, 2016)A model is a simplified representation of the real world. Model uncertainty is a common issue in predictive models, and discussions on this can be found in many subjects. Model uncertainty is a branch of uncertainty analysis ... -
Modeling Human and Organizational Factors for Operational Risk Analysis
(Master thesis, 2016)In terms of accident sequences in the offshore oil and gas industry, technical factors have been focused on the risk analysis area widely. However, there are still accidents and losses occurred frequently. To understand ... -
Modelling of Technical, Human and Organisational Factors of Ship Grounding Accidents with the use of Bayesian Belief Networks
(Master thesis, 2016)In recent years, the management of risk has developed towards a risk based approach. Thus, industries need to have a comprehensive understanding of why accidents occur and how they develop. In order to act successfully in ... -
NewModel for Reliability and Availability Assessment of Subsea BOP System - Challenges and Approaches for New Requirements
(Master thesis, 2015)The blowout preventer system is acting the secondary safety barrier in a hydrocarbon well, where the drilling mud column is defined as the primary safety barrier. However, in pratical industry, there is a new demand for ... -
Optimization of Design, Safety and Cost of Pressure Protection Systems
(Master thesis, 2016)The purpose and application of the High Integrity Pressure Protection System (HIPPS) has been explored, both in general and in the specific case for Kristin. As the HIPPS was a fairly novel off- shore technology in 2005, ... -
Performance of dynamic safety barriers-Structuring, modelling and visualization
(Master thesis, 2014)The main objective of this master thesis is to discuss performance of dynamic safety barriers. A comprehensive literature review is performed in order to get understanding what dynamic safety barrier is. Three different ... -
Prediction of failure rates for subsea equipment
(Master thesis, 2016)Prediction of failure rate for new subsea equipment is a challenge in oil and gas industry mainly due to lack of relevant data and use of increasingly novel technologies. There is a lack of common guideline or framework ... -
