Blue-Chip or Sub-Standard?: A data interrogation approach to identify safety characteristics of shipping organisations
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:8, Doctoral thesis, 2004) The objective of this thesis describes the characteristics that distinguish shipping companies that have a superior safety standard, called blue-chip, from those being substandard. The different characteristics of ... -
Boarding control system for improved accessibility to offshore wind turbines: Full-scale testing
(Journal article; Peer reviewed, 2015)This paper considers the dynamic modelling and motion control of a Surface Effect Ship (SES) for safer transfer of personnel and equipment from vessel to-and-from an offshore wind-turbine. The control system designed is ... -
Bond Graph Modeling of Marine Power Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:56, Doctoral thesis, 2009)Mathematical models for an All Electric Ship component library is developed in this thesis. The main motivation for writing this thesis is to develop a model library that gives the opportunity to simulate both existing ... -
Bond Graph Modelling of Fuel Cells for Marine Power Plants
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:161, Doctoral thesis, 2009)There is a constant search for alternative solutions improving the fuel efficiency and environmental impact of marine power plants. Fuel cells are regarded as a potential future candidate for significantly reducing pollution ... -
Bondline thickness effects on damage tolerance of adhesive joints subjected to localized impact damages: Application to leading edge of wind turbine blades
(Peer reviewed; Journal article, 2021)The leading edges of wind turbine blades are adhesively bonded composite sections that are susceptible to impact loads during offshore installation. The impact loads can cause localized damages at the leading edges that ... -
Breaking Characteristics and Geometric Properties of Spilling Breakers over Slopes
(Journal article; Peer reviewed, 2015)A two-phase flow CFD model based on the Reynolds-Averaged Navier–Stokes (RANS) equations coupled with the level set method (LSM) and k − ω turbulence model is used to simulate spilling breakers over a sloping bed. In order ... -
Broken Ice Loads on Floating Wind Turbine
(Master thesis, 2022)I interessen for å designe flytende vindturbiner for kalde områder med flytende havis, utvides det tilgjengelige tekniske verktøysettet i denne oppgaven. SIMA, en programvare for marine operasjoner og fortøyningsanalyse, ... -
Bucket Foundation in Clay for OWT Subjected to Combined Cyclic Loads
(Master thesis, 2014)This thesis project investigates the bucket foundation in clay subjected to cyclic loads. The cyclic irregular loading history in this thesis was represented by the equivalent number of cycles Neq with a certain level of ... -
Buckling and Load Shedding in Redundant Plated Ship Structures
(Master thesis, 2016)A linear Finite Element(FE) procedure developed by DNV GL as an alternative to standard design procedures for redundant plated panels has been tested and evaluated. The method is based on modifying the so-called macro ... -
Buckling and Post-Buckling Behaviour of Extruded Aluminium Panels Subject to the Combined Effects of Welding and Pitting Corrosion
(Chapter, 2023)The present study investigates the effects of pitting corrosion and welding, both independently and combined, on the buckling and post-buckling behaviour of extruded aluminium panels. For this purpose, a finite element ... -
Buckling of Cylindrical Shells with a Granular Core Under Global Bending: Strength Gains and Imperfection Sensitivity
(Master thesis, 2014)Thin cylindrical shells are commonly employed in civil and structural applications in which the dominant loading condition is global bending. In applications such as wind turbine towers and offshore piles, the design of ... -
Buckling of Non-spherical MOSS-LNG Tanks
(Master thesis, 2020)Etterspørselen etter store LNG-skip har økt. Den enkleste måten å øke kapasiteten til Moss LNG-skip er å øke diameteren til de sfæriske tankene, og dermed også skipets bredde. På grunn av begrensningene på skipets dimensjoner ... -
Buckling of Non-spherical Moss-LNG tank
(Master thesis, 2019)Etterspørselen etter skip som kan frakte mer LNG har økt de siste årene ifølge Moss Maritime. Den uavhengige sfæriske tanken av type B fra Moss Maritime må modifiseres hvis et skip skal frakte mer LNG. Tanken kan ikke ... -

Buckling strength analysis of aluminium plates with varying panel thickness and heat-affected zone patterns
(Master thesis, 2021)Aluminium er ett materiale med mange verdifulle egenskaper industrien kan dra nytte av. Dets høye spesifikke styrke gjør det til en ypperlig kandidat til å bygge lette skrog til hurtiggående båter med lavere klima utslipp ... -
Building safety in the offshore petroleum industry: Development of risk-based major hazard risk indicators at a national level
(Journal article; Peer reviewed, 2019)There has been an important controversy over whether the series of major accidents at Chinese Bohai Bay in 2011, i.e. the Penglai 19-3 and Suizhong 36-1 oil spills, are a sign of systematic safety problems in the Chinese ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
(Peer reviewed; Journal article, 2021)In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery with a large mesh top panel
