Human Technical Factors in FPSO-Shuttle Tanker interactions and their influence on the Collision Risk during Operations in the North Sea
K. Lundborg, Magne Erik (Master thesis, 2014)Following a series of collisions and near-misses, involving shuttle tanker and FPSO performing tandem offloading operations in the North Sea, extensive effort was put to address the issue in the early 2000 s. The aim of ... -
Improving safety of DP operations: learning from accidents and incidents during offshore loading operations
Dong, Yining; Vinnem, Jan Erik; Utne, Ingrid Bouwer (Journal article; Peer reviewed, 2017)The risk caused by DP vessels in offshore marine operations is not negligible, due to wide applications of DP vessels in complex marine operations, and the sharp increase of DP vessel population. The DP accidents/incidents ... -
Inherent safety assessment: current state of the art and why is still not effectively adopted by industry
Haugen, Stein; Vinnem, Jan Erik; Dahlsveen, Jan; Sultana, Sharmin (Chapter, 2020)Inherent safety is a proactive approach to risk reduction. The industry should adopt it in the early stages of design as it is the most prominent approach to risk reduction, as described by experts. Researchers have worked ... -
Maintenance of petroleum process plant systems as a source of major accidents?
Vinnem, Jan Erik; Haugen, Stein; Okoh, Peter (Journal article; Peer reviewed, 2016)The prevention of hydrocarbon leaks is of great importance as they are the most critical precursor events that may lead to major accidents on petroleum facilities. Maintenance of process components on offshore and onshore ... -
Major accident prevention illustrated by hydrocarbon leak case studies: A comparison between Brazilian and Norwegian offshore functional petroleum safety regulatory approaches
Almeida, Alex Garcia de; Vinnem, Jan Erik (Journal article; Peer reviewed, 2020)Despite laws, regulations, or risk management tools designed to avoid loss events, a hydrocarbon leak (HCL) in an offshore oil and gas platform1 is a major hazard event that reveals failures in risk control. In addition, ... -
Major Accidents in Exposed Fish Farming - A quantitative collision risk analysis
Lunde, Karoline (Master thesis, 2018)The Norwegian aquaculture industry has had a large increase in activity over the last years, and the expansion is expected to continue in the years to come. However, a further expansion of traditional fish farming is not ... -
