Data driven approach to risk management and decision support for dynamic positioning systems
Parhizkar, Tarannom; Hogenboom, Sandra; Vinnem, Jan Erik; Utne, Ingrid Bouwer (Peer reviewed; Journal article, 2020)Offshore oil and gas operations are inherently associated with risk and may have catastrophic consequences to life, property, and environment. Risk management is thus performed during the design, planning, and operation ... -
Dynamic probabilistic risk assessment of decision-making in emergencies for complex systems, case study: Dynamic positioning drilling unit
Parhizkar, Tarannom; Utne, Ingrid Bouwer; Vinnem, Jan Erik; Mosleh, Ali (Peer reviewed; Journal article, 2021)Decision-making in emergency situations is a risky and uncertain process due to the limited information and lack of time. Some key problem parameters, such as the time required to complete important response tasks, must ... -
Sizing Optimization of a Hybrid Shipboard Power System for Low-Emission Shipping
Michaelsen, Tor Magnus Clemens Kvinnsland (Master thesis, 2019)Valget av maskinerisystemet for et skip er i utgangspunktet en kompleks oppgave. Skip er konstruert med tanke på en levetid på 20-25 år, og vil derfor være utsatt for både endringer i operasjonelle krav, så vel som ... -
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. Ensuring safe operation of safety-critical autonomous systems is paramount, typically ...
