Process Safety and Risk Management using System Perspectives - A contribution to the chemical process and petroleum industry
Sultana, Sharmin (Doctoral theses at NTNU;2022:323, Doctoral thesis, 2022)Risk management is all activities used to manage the risk of hazardous events and provides information to improve decision-making. A typical approach to system safety is to identify and eliminate the causes of an accident ... -
Reliability Analysis for Physically Separated Redundant System
Kim, HyungJu; Haugen, Stein; Utne, Ingrid Bouwer (Chapter, 2017)Redundancy has been a key concept to achieve high system reliability in technical systems, and the concept is central in modern technology regulations. One important aspect of successful redundancy is independence of the ... -
Review and comparison of existing risk analysis models applied within shipping in ice-covered waters
Xu, Sheng; Kim, Ekaterina; Haugen, Stein (Peer reviewed; Journal article, 2021)With the changing climate and declining extent of sea ice, the activities in the Arctic region have become increasing significantly. Compared to the environments with ice-free waters, the harsh environment in the Arctic ... -
Risikobasert design av fartøy og merde for eksponert havbruk
Hole, Jens Kristian (Master thesis, 2017)Jorden står ovenfor en befolkningsvekst, som setter stort press på matproduksjonen. Havbruk kan være en egnet metode for å produsere bærekraftig mat, ettersom jordens overflate består av ca. 72% sjøvann. For å gjennomføre ... -
Risk acceptance criteria for autonomous ships
Kristensen, Susanna Dybwad (Master thesis, 2021)Målet med denne oppgaven er å foreslå risikoakseptkriterier for autonome skip. Omfattende forskning blir gjort på temaet autonome skip, og flere konsepter for autonom transport til sjøs har blitt utviklet. Per nå kreves ... -
Risk assessment of collisions of an autonomous passenger ferry
Guo, Chuanqi; Haugen, Stein; Utne, Ingrid Bouwer (Peer reviewed; Journal article, 2021)Autonomous transportation is an increasingly popular concept and is gradually becoming a reality. This transformation also changes the way people travel. For example, the autonomous ferry is an emerging alternative for ... -
