Decisions and decision support for major accident prevention in the process industries
Kongsvik, Trond; Almklov, Petter; Haavik, Torgeir K; Haugen, Stein; Vinnem, Jan Erik; Schiefloe, Per Morten (Journal article, 2015)Decision making is a central component in the management of safety-critical operations. Some attempts have been made to employ Quantitative Risk Analysis as input to such decisions. Although adequate for long-term planning ... -
Design of a Small Autonomous Passenger Ferry
Havdal, Gina; Heggelund, Christina Torjussen; Larssen, Charlotte Hjelmseth (Master thesis, 2017)The main objective of this study is to determine the design of an autonomous ferry to transport people between Ravnkloa and Fosenkaia in Trondheim. It will also be considered whether or not it will be a better solution ... -
Design of service vessels for operations in exposed aquaculture
Andersen, Dani (Master thesis, 2021)Havbruksnæringen er blant de mest risikopåvirkende yrkene i norsk industri, når det gjelder omkomne. Utvidelsen av havbruksnæringen mot mer utsatte områder kan lede til en risikoøkning, på grunn av usikkerheten av hvordan ... -
Developing a Risk Model for Fire in Passenger Ships - Based on Bayesian Belief Network
Dokmo, Hanne Bjørkås (Master thesis, 2016)Passenger ships, especially cruise ships, are rapidly increasing in size. With larger vessels, comes a greater risk to the passengers if something where to happen. A fire on a passenger vessel can spread quickly, and with ... -
Development of a Risk Model for Fish Farming Operations
Nordtvedt, Helene (Master thesis, 2016)Fish farming has grown to become one of Norway s largest export industries. By 2050, Norway has the potential of producing 50 million tons of fish each year, if challenges related to the production and environment are ... -
Development of an inherent system safety index (ISSI) for ranking of chemical processes at the concept development stage
Haugen, Stein; Sultana, Sharmin (Peer reviewed; Journal article, 2022)Inherently safer design is the most proactive approach to manage risk, as referred by scientists and experts. Researchers have adopted various methods in evaluating inherent safety indices like parameter-based indexing, ... -
Dynamic risk analysis for operational decision support
Haugen, Stein; Edwin, Nathaniel John; Vinnem, Jan Erik; Brautaset, Olav (Chapter, 2017)Safe design of complex technical systems with a potential for major accidents is often supported by Quantitative Risk Analyses (QRA). The QRA has developed over several decades and the offshore oil and gas industry in ... -
Dynamic Risk Analysis for Operational Decision Support
Haugen, Stein; Edwin, Nathaniel John (Journal article; Peer reviewed, 2017)Quantitative risk assessments for offshore oil and gas installations have been developed and used to support decision making about major hazards risk for more than 30 years. Initially, these studies were used to support ... -
Enhancing the basis for Crew Resource Management (CRM) training for well operations crews: Risk Influencing Factors in Offshore Drilling
Kvalheim, Sverre Andreas; Haugen, Stein (Chapter, 2015)The offshore drilling industry is experiencing a stronger focus on human and organizational factors that are influencing risk of major accidents. Industry associations, authorities and drilling operators are starting on ... -
An extended FRAM method to check the adequacy of safety barriers and to assess the safety of a socio-technical system
Sultana, Sharmin; Haugen, Stein (Journal article; Peer reviewed, 2023)Safety barriers are used in the system to prevent unwanted events and accidents. Traditional approaches like fault tree or bow-tie method use linear accident models without considering complex interactions of failures of ... -
Factors in offshore planning that affect the risk for major accidents
Sarshar, Sizarta; Haugen, Stein; Skjerve, Ann Britt (Journal article; Peer reviewed, 2015)The purpose of this paper is to systematically analyse a typical planning process in the offshore industry from the perspective of causes of major accidents, with the ultimate aim of identifying factors that affect the ... -
Hazard analysis: Application of STPA to ship-to-ship transfer of LNG
Sultana, Sharmin; Okoh, Peter Ichekani; Haugen, Stein; Vinnem, Jan Erik (Journal article; Peer reviewed, 2019)The process industry has experienced technological advances, such as automatic handling of hazardous substances, process equipment, and valves. High levels of automation, as well as system interactions at component and ... -
Human Factors Analysis of Operational Activities
Hoque, Muhammed Ridwanul (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 ... -
Identification of safety indicators in aquaculture operations based on fish escape report data.
Holmen, Ingunn Marie; Utne, Ingrid Bouwer; Haugen, Stein (Peer reviewed; Journal article, 2021)Finfish farming is the most common aquaculture mode in Europe.
