Analysis and Design of Columns in Offshore Structures subjected to Supply Vessel Beam Collisions
Kristiansen, Line (Master thesis, 2013)The recommended force-deformation curves for supply vessels collision presented in NORSOK N-004 are based on simplified methods and tests developed more than 30 years ago. The purpose of this work is to contribute to the ... -
Analysis and Design of Columns in Offshore Structures subjected to Supply Vessel Collisions
Watan, Reny (Master thesis, 2011)The assessment had been conducted for shipside collision against unstiffened, inclined jacket leg segment (column). The inclined column has been modelled with horizontal-to-vertical ratio of 1/7. Two types of boundary ... -
Analysis and Design of Floating Bridge over Bjørnefjorden - Floating Bridge Subjected to Large Ship Collisions
Eldegard, Ole (Master thesis, 2017)In This Master s Thesis, a bridge design for the crossing of Bjørnafjorden have been investigated. The design was developed in a cooperation between COWI, Aas Jakobsen, Johs Holte As and Global Maritime, as a part of The ... -
Analysis and design of offshore tubular members against ship impacts
Yu, Zhaolong; Amdahl, Jørgen (Journal article, 2018)Ship collisions may be critical to the operational safety of ships and offshore structures, and should be carefully designed against. This paper investigates the response of offshore tubular members subjected to vessel bow ... -
Analysis and Design of Ship Collision Barriers on a Submerged Floating Tunnel subjected to Large Ship Collisions
Hansen, Jørgen Lima (Master thesis, 2015)The Norwegian Public Roads Administration (NPRA) is running the project "Ferry free coastal route E39". One of the main challenging are regarding how to cross the wide and deep fjord on the west coast of Norway. One of the ... -
Analysis and Design of Ship Collision Barriers on a Submerged Floating Tunnel subjected to Large Ship Collisions
Århus, Gisle Hoel (Master thesis, 2016)Reinertsen AS is developing a bridge crossing concept to cross the Sognefjord in Norway. The concept consists of floating bridge and submerged tunnel. The submerged tunnel is exposed to ship collisions from passing ship ... -
Analysis and Design of Ship Collision Barriers on a Submerged Floating Tunnel subjected to Large Ship Collisions
Rødland, Sindre (Master thesis, 2017)In this thesis, the global response of a floating bridge, with a submerged floating tunnel at the midspan, is studied when subjected to high energy ship impacts. The bridge is a concept pro- posed for use when crossing ... -
Analysis and Design of Stiffened Columns in Offshore Floating Platforms Subjected to Supply Vessel Impacts
Bøe, Terje Skogan (Master thesis, 2018)In this work the resistance of a stiffened column exposed to stern corner impacts is studied. The effect of ring and vertical stiffeners are explored, as well as the effect of decks and bulkheads. It is found that the ring ... -
Analysis and design of the SEVAN FPSO against extreme ice actions
He, Zhengmin (Master thesis, 2014)Generally, the main objective of this thesis has been completed for the improvement of previous master thesis work. The preparation and background review are accomplished quite sufficient and reflects a good understanding ... -
Analysis of accidental iceberg impacts with large passenger vessels
Wang, Suyu (Master thesis, 2017)The number of collisions between ships and ice are increasing with the increase of ships sailing in Arctic areas. It is necessary to research on large passenger ships subjected to iceberg impact, since it may cause huge ... -
Analysis of accidental iceberg impacts with large passenger vessels and FPSOs
Radhakrishnan, Gowtham (Master thesis, 2018)This Master thesis is part of the degree for the Nordic Masters in Maritime Engineering -
Analysis of accidental iceberg impacts with LNG tank carriers
Dahl, Knut Aaberge (Master thesis, 2012)The number of collisions between ships and icebergs are increasing in correlation with the increase of the number of ships sailing in Arctic areas. Due to the exploitation of gas fields in Arctic areas, the LNG shipping ... -
Analysis of an Offshore Jacket subjected to Supply Vessel Impacts
Flatøy, Erlend (Master thesis, 2018)In this master s thesis an offshore jacket platform subjected to supply vessel impacts is analysed. Since the supply vessels have increased in size and have been reinforced through modern ship design it has been of ... -
Analysis of Dropped Objects on Offshore Installations
Ramberg, Amalie (Master thesis, 2022)Denne masteroppgaven tar for seg den strukturelle responsen av et avstivet panel etter støt fra fallende laster, med hovedvekt på en fallende container. Responsen er funnet ut fra den ikke-lineær elementmetoden med ... -
Analysis Of Floater Supported Offshore Wind Turbines
Vu, Lucia Hanh Tran (Master thesis, 2022)Forbedrede fornybare løsninger blir kontinuerlig studert og evaluert med fokus om å redusere det menneskeskapte CO2-fotavtrykket. En av de mest lovende fornybare energiressursene de kommende tiårene er flytende vindkraft. ... -
Analysis of Floating Offshore Wind Turbine Subjected to Ship Collisions
Rypestøl, Martin (Master thesis, 2020)Flytende offshore vindmøller er, i likhet med andre offshore strukturer, utsatt for skipskollisjoner. Fremtidige vindparker kan bli plassert i nærhet av skipstrafikk, og tøffere værforhold sørger også for større forsyningsskip. ... -
Analysis of Ice-Induced Damages to a Cargo Carrier and Implications wrt. Rule Requirements
Lyngra, Nora Helen Lund (Master thesis, 2014)In this thesis, an ice-induced damage to a DNV-GL registered cargo ship isinvestigated by looking into its damage survey report, and running nonlinearfinite element analyses. The analyses are used for regeneration of the ... -
Analysis of Ice-Induced Vibrations and Comparison with Full-Scale Experimental Data
Meese, Andreas Nordby (Master thesis, 2013)In the present work, a model which estimates the fatigue life for a cylindrical structure interacting with ice is developed. The model is based on the lighthouse of Norströmsgrund, and estimates the fatigue damage for one ... -
