Probabilistic assessment of first-year ice ridge loads on offshore structures
(Doctoral theses at NTNU;2024:45, Doctoral thesis, 2024)Advancements in technological capabilities, growing energy demands, and climate change are making offshore regions with floating sea ice increasingly attractive for infrastructure development. Notable examples include the ... -
Probabilistic Assessment of Ice Environment and Ridge Loads for the Norströmsgrund Lighthouse
(Chapter, 2018)Structural reliability analysis requires statistical distribution of the loads. One such case is ice load calculation for offshore structures. Ice-structure interaction is a highly stochastic phenomenon due to the natural ... -
Probabilistic assessment of ice rose diagrams for ice drift in the beaufort sea
(Journal article; Peer reviewed, 2019)The intention of this paper is to introduce the ice rose diagram, which is a graphical tool that makes it possible to display the ice drift speed, the occurrence frequency, and the drift direction at a particular location ... -
Probabilistic autoencoder-based bridge damage assessment using train-induced responses
(Peer reviewed; Journal article, 2024)Structural health monitoring (SHM) systems have been increasingly employed to continually assess the current state of bridges. However, the vast amounts of sensor data generated by SHM systems, along with constantly changing ... -
Probabilistic Damage Stability - Evaluating the Attained Subdivision Index by Analysing the Effect of Changes in the Arrangement and Intact Stability for an Offshore Vessel
(Master thesis, 2016)The motivational basis and underlying goal of this master s thesis is to provide more knowledge to the experience data bank for ship designers with respect to probabilistic damage stability (PDS). More precisely, the ... -
Probabilistic Damage Stability - Maximizing the Attained Index by Analyzing the Effects of Changes in the Arrangement for Offshore Vessels
(Master thesis, 2015)Probabilistic damage stability calculations are time demanding and are conducted at a late stage of the design process. A detailed arrangement is required to calculate whether a ship fulfills the requirements. To minimize ... -
Probabilistic Design of Midship Panel based on Model scale compressive Ice Test
(Master thesis, 2013)This thesis is investigating compressive ice loads acting on the mid-ship using a model experiment performed in Aalto ice tank where atactile sensor was mounted on the side. In order to get insight in thevery complex ... -
Probabilistic Design of Sustainable Reinforced Concrete Infrastructure Repairs Using SIPmath

Probabilistic estimates of permissive areas for undiscovered seafloor massive sulfide deposits on an Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2018)Norway explores its seabed mining potential including exploration studies on seafloor massive sulfides (SMS) at the outermost parts of its continental shelf, the Mohn’s Ridge. Owing to the significant development potential ... -
Probabilistic estimation of fatigue loads on monopile-based offshore wind turbines - Application to sensitivity assessment & clustering optimization for support structure cost reduction
(Master thesis, 2015)Offshore wind energy faces three important trends: (1) wind farms grow in size, (2) monopiles are installed in deeper water, and (3) cost reduction remains the most important challenge. With wind farm size, the importance ... -
Probabilistic fatigue model for design and life extension of mooring chains, including mean load and corrosion effects
(Peer reviewed; Journal article, 2022)A probabilistic model for mooring chain fatigue damage is developed based on the S–N approach. The effects of mean load and corrosion condition on the fatigue capacity of the chains are included by adopting a parameterized ... -
Probabilistic finite element analysis of failures in concrete dams with large asperities in the rock–concrete interface
(Peer reviewed; Journal article, 2023)Common analytical assessment methods for concrete dams are unlikely to predict material fracture in the dam body because of the assumption of rigid body behavior and uniform- or linear stress distribution along a predetermined ... -
A Probabilistic Framework for the Fatigue Damage Assessment of Ships Navigating through Level Ice Fields
