Structural Reliability Analysis of Intact and Damaged Ships in A Collision Risk Analysis Perspective
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:17, Doctoral thesis, 2011)Risk-based design is growing in importance due to the need of obtaining measures of the safety to aid making decisions regarding the optimal balance between safety and economy. Design against Accidental Limit State (ALS) ... -
Structural reliability analysis of secondary hull detail
(Chapter, 2023)A reliability model for analyzing the possible occurrence of crack propagation of a secondary structural detail is developed. Vibration response due to engine excitation is formulated by a stochastic model based on analysis ... -
Structural Reliability Analysis of the Hardanger Bridge using an enhanced Monte Carlo Method
(Master thesis, 2014)In the present study, a reliability analysis of the Hardanger Bridge was performed, by assessing the probability that multimodal flutter will occur. The self-exiting forces which reduce the effective damping and stiffness ... -

(Journal article; Peer reviewed, 2017)The paper presents a detailed review of the state-of-the-art research activities on structural reliability analysis of wind turbines between the 1990s and 2017. We describe the reliability methods including the first- and ... -
Structural reliability based position mooring
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:62, Doctoral thesis, 2008)This thesis considers control of moored marine structures, referred to as position mooring. Moored marine structures can take on a number of different forms, and two applications are considered in this work, namely ... -
Structural resistance of polar ships and FPSO´s to ice loading
(Master thesis, 2012)Due to the substantial increase in oil and gas activities in Polar areas the demand for ice strengthen vessel has increased greatly. This increase in demand has highlighted the importance of designing ice strengthened ship ... -
Structural resistance of polar ships to ice loading: Discussion of the IACS Polar rules considering different structural and methodological aspects
(Master thesis, 2013)Generally, the design of ships and offshore structures intended for operation in ice infested waters has been based upon elastic methods of plasticity. However, through development of knowledge regarding the true behaviour ... -
Structural resistance of ship and offshore structures exposed to the risk of brittle failure
(Doctoral theses at NTNU;2020:338, Doctoral thesis, 2020)The thesis aims to present the possibility of brittle failure in ship and offshore structures at low temperatures, and propose a material failure criterion for the prediction of ductile-brittle fracture transition in ... -
Structural Response Analysis and Fatigue Damage Estimation of a Floating Bridge Subjected to Inhomogeneous Wave Loads
(Chapter, 2020)In this paper, a computational study of the structural responses of a floating bridge for crossing of the Bjørnafjord in Norway is presented. The study employs an idealized floating bridge model developed based on the phase ... -
Structural Response in Ship-Platform and Ship-Ice Collisions
(Doctoral thesis at NTNU;2016:14, Doctoral thesis, 2016)Collision events may have severe consequences, and it is important to design both ship and offshore structures so that they have sufficient resistance to a collision event. The main purpose of the work herein is to improve ... -
Structural restoration of Mesozoic rifting phases in the northern North Sea
(Master thesis, 2013)Structural restoration has been carried out on the northern North Sea (60-62ºN), based on the reprocessed, interpreted and depth converted seismic lines NSDP84-1 and 2. Two major rifting events have previously been recognized ... -
