Screening LCA of GHG emissions related to LNG as ship fuel
Ryste, Julianne Mari (Master thesis, 2012)In view of the increasingly popular climate change debate worldwide, maritime transport is under pressure to create sustainable solutions for a cleaner future.One of these solutions is using liquefied natural gas (LNG) as ... -
Spare Parts Evaluation in the Oil and Gas Industry
Fehn, Manuel Andre (Master thesis, 2015)The main objective of this master thesis is to develop a generic spare parts evaluation process flow based on NORSOK Z-008 and the daily practice in the Norwegian oil and gas industry. Additionally, a case study has been ... -
Spare Parts Management Methodology Development and Cost Evaluation - For offshore production facilities
Qvale, Vilde Elisabeth Aas (Master thesis, 2017)In the aftermath of the drop in oil price in 2014, the global energy industry has been in constant search for new business areas and more cost efficient solutions in order to stay competitive. The industry quickly recognized ... -
State-of-the-Art on Artificial Intelligence for Risk-based Decision-making in Autonomous Marine Vehicles
Maidana, Renan Guedes; Utne, Ingrid Bouwer; Sørensen, Asgeir Johan (Chapter, 2020)Risk assessment (i.e., risk analysis and risk evaluation) is routinely performed in marine operations by vessel crews to inform and support the decision-making process for the ship’s operations. With the inevitable ubiquity ... -
Supervised Dynamic Probabilistic Risk Assessment of Complex Systems, Part 1: General Overview
Parhizkar, Tarannom; Vinnem, Jan Erik; Utne, Ingrid Bouwer; Mosleh, Ali (Peer reviewed; Journal article, 2021)Dynamic probabilistic risk assessment (DPRA) is a systematic and comprehensive methodology that has been used and refined over the past decades to evaluate risks associated with complex systems. However, current approaches ... -
Supervised dynamic probabilistic risk assessment of complex systems, part 2: Application to risk-informed decision making, practice and results
Parhizkar, Tarannom; Utne, Ingrid Bouwer; Vinnem, Jan Erik; Mosleh, Ali (Peer reviewed; Journal article, 2021)One challenge that has received attention in maritime industry is assessing the risk level of dynamic positioning (DP) systems in emergency situations. Statistics from recent years have shown that the risk level of some ... -
Supervised dynamic probabilistic risk assessment: Review and comparison of methods
Guedes Maidana, Renan; Parhizkar, Tarannom; Gomola, Alojz; Utne, Ingrid Bouwer; Mosleh, Ali (Peer reviewed; Journal article, 2022)With the adoption of autonomous systems in higher levels of autonomy, large-scale, complex and dynamic systems are becoming commonplace.
