Accidental Impact Resistance of non-disconnectable bouy type FPSO
Slagstad, Martin (Master thesis, 2014)The surroundings of offshore structures consist of many components controlled by nature, but also some that are managed by people- ships. Due these factors, ship collisions are a constant threat to offshore installations ... -
Evaluation of Nonlinear Material Behavior for Offshore Structures Subjected to Accidental Actions
Amdahl, Jørgen; Storheim, Martin; Alsos, Hagbart Skage (Journal article; Peer reviewed, 2018)Evaluation of the nonlinear structural response of any structure is a challenging task; a range of input parameters are needed, most of which has significant statistical variability and the evaluations require a high degree ... -
Iceberg shape characterization for damage assessment of accidental impacts with ships and offshore structures
Myhre, Torstein (Master thesis, 2013)The northern areas are becoming more and more attractive because off the large oil and gas reservoir that is there. In this area there is a harsh environment and the possibility to collide with an iceberg increases as the ... -
Laboratory experiments on shared-energy collisions between freshwater ice blocks and a floating steel structure
Kim, Ekaterina; Storheim, Martin; Amdahl, Jørgen; Løset, Sveinung; von Bock und Polach, Rüdiger Ulrich Franz (Journal article; Peer reviewed, 2017)Ship collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. ... -
Pilot study of ice-structure interaction in a pendulum accelerator
Storheim, Martin; Nord, Torodd Skjerve; Kim, Ekaterina; Høyland, Knut Vilhelm; Langseth, Magnus; Amdahl, Jørgen; Løset, Sveinung (Journal article; Peer reviewed, 2015)More knowledge on the coupled response of ice and structure in collision in which both bodies undergo permanent damage is needed. These types of experiments are challenging to perform in a laboratory at relatively high ... -
Probabilistic material modeling of iceberg for analysis of accidental impacts with ships and offshore structures
Bøhlerengen, Simen (Master thesis, 2013)There has been an increasing interest of maritime and offshore operations in the arctic regions for some decades now. In arctic regions there are icebergs which can?t be neglected. The first part of this thesis is an ... -
Structural Design Considerations for an Ice Resistant Semi Submersible Drilling Rig
Jacobsen, Heidi (Master thesis, 2014)Arctic areas contain large oil and gas fields demanding robust drilling and field development solutions. Semi submersible drilling and completion rigs are highly used for the current operations. Operating while surrounded ... -
Structural Response in Ship-Platform and Ship-Ice Collisions
Storheim, Martin (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 ... -
Understanding the effect of assumptions on shell plate thickness for arctic ships
Kim, Ekaterina; Amdahl, Jørgen; Storheim, Martin; Løset, Sveinung (Journal article; Peer reviewed, 2015)The presence of ice requires specially constructed ships. The biggest challenge in this aspect is ice loads on ship’s hull: processes of deformation and fracture of ice are not fully understood and ice geometry and mechanical ...
