Allision risk analysis of offshore petroleum installations on the Norwegian Continental Shelf—an empirical study of vessel traffic patterns
Hassel, Martin; Utne, Ingrid Bouwer; Vinnem, Jan Erik (Journal article; Peer reviewed, 2017)The Norwegian Petroleum Safety Authority (PSA) requires offshore petroleum operators on the Norwegian Continental Shelf (NCS) to perform risk assessments of impacts (allisions) between passing ships and offshore installations. ... -
An allision risk model for passing vessels and offshore oil and gas installations on the Norwegian Continental Shelf
Hassel, Martin; Utne, Ingrid Bouwer; Vinnem, Jan Erik (Peer reviewed; Journal article, 2020)This article presents a new risk model for estimating the probability of allision risk (the impact between a ship under way and a stationary installation) from passing vessels on the Norwegian Continental Shelf (NCS). ... -
Analysis of Accelerometric Datasets for Wind Turbine Monitoring
Rolfseng, Jon Henning (Master thesis, 2016)An approach using accelerometric datasets for condition monitoring of wind turbines is developed and applied specifically to the planetary stage of the gearbox. -
Analysis of current ROV Operations in the Norwegian Aquaculture - Reducing Risk in exposed Aquaculture Operations
Solem, Anne Jieli Louise (Master thesis, 2017)The Norwegian aquaculture is already considered to be one of the most dangerous occupations when it comes to risk, and the risk is likely to be amplified as the industry wants to expand and utilize more exposed areas. These ... -
Analysis of Dynamic Positioning System Accidents and Incidents with Emphasis on Root Causes and Barrier Failures
Dong, Yining; Rokseth, Børge; Vinnem, Jan Erik; Utne, Ingrid Bouwer (Chapter, 2017)The accidental statistics from 2003 to 2013 revealed that the frequency of floating production storage and offloadingshuttle tanker (FPSO-ST) collision risk was significantly above the cut-off limit. There is a need for ... -
Analysis of Loss of Position Incidents for Dynamically Operated Vessels
Hauff, Kristian Stenvågnes (Master thesis, 2014)This project sought to identify the causal factors related to loss of position incidents for dynamically positioned vessels, and to explore the possibility of using a Bayesian Belief Network (BBN) to model the identified ... -
Applicability of current remotely operated vehicle standards and guidelines to autonomous subsea IMR operations
Hegde, Jeevith; Utne, Ingrid Bouwer; Schjølberg, Ingrid (Chapter, 2015)This paper employs a combination of literature review and case study methodology to assess the gap between current remotely operated vehicle (ROV) standards and future autonomous IMR operation requirements. With advent of ... -
Application of fuzzy logic for safe autonomous subsea IMR operations
Hegde, Jeevith; Utne, Ingrid Bouwer; Schjølberg, Ingrid; Thorkildsen, Brede (Chapter, 2015)Numerous technical and knowledge gaps pose challenges towards implementation of autonomous subsea intervention, maintenance, and repair operations. One such gap is related to development of methods for ensuring subsea asset ... -
Application of RCM Principles to Identify Barriers in Design of Unmanned Engine Rooms for Oceangoing Merchant Vessels
Jacobsen, Nikolai Havikbotn (Master thesis, 2016)Research has shown that unmanned merchant vessels are possible, and researchers have claimed that larger autonomous vessels can be seen within 10 years. For oceangoing vessels, one of the biggest challenges is to get systems ... -
