Assessment of structural damage due to cryogenic spill for FLNG plants: Beregning av konstruksjonsskade som følge av kryogenske utslipp på flytende LNG anlegg
(Master thesis, 2014)To investigate the effect of cooling by liquified natural gas, literature on the topic wasinvestigated in prior project work. Test results for cooling of steel by liquid nitrogen wascompared to numerical solutions of heat ... -
Effects of Pretension in Bolt for a Slewing Bearing
(Master thesis, 2014)This thesis is to check to bolt pretension for high duty bolted joint in the slewing ring. The bolted joint in the slewing ring is of special type the loads acts off axis of the bolt. For this kind of bolted joint, there ... -
Theory and Experiments of a Free-Running Fishing Vessel in Stern Sea
(Chapter; Peer reviewed, 2014)Hydrodynamic aspects of a modern fishing vessel during manoeuvring in a seaway was studied theoretically and experimentally. The focus was on small frequencies of encounter, corresponding to following and stern quartering ... -
Modeling and Control for Dynamic Positioned Marine Vessels in Drifting Managed Sea Ice
(Journal article; Peer reviewed, 2014)This paper presents a development framework for dynamic positioning control systems for marine vessels in managed ice. Due to the complexity of the vessel-ice and ice-ice interactions a configurable high fidelity numerical ... -
Ultimate Strength and Post-Ultimate Behavior of Hybrid Platform Deck Girders
(Master thesis, 2014)As for the increasing demands of offshore oil and gas, the new platforms are designed in more and more serious conditions. The safety check and modification of the complex structure has become a hot subject. Normally, the ... -

Pigment Composition of Macroalgae from a Norwegian Kelp Forest
(Master thesis, 2014)Variation in pigment composition between seasons in 10 different species of macroalgae was examined using high precision liquid chromatography (HPLC). In addition, a study on the variation of pigment quantity and quality ... -
Development of a Risk Management Process for NTNU's REMUS 100 AUV
(Master thesis, 2014)Autonomous underwater vehicles (AUV) are highly complex electromechanical systems which act in a hazardous, unstructured environment. The AUR Lab of NTNU operates one REMUS 100 AUV and several other unmanned underwater ... -
Stokes drift estimation for deep water waves based on short-term variation of wave conditions
(Journal article, 2014)The paper provides a simple analytical method which can be used to give estimates of the Stokes drift based on short-term variation of wave conditions. This is achieved by providing bivariate distributions of wave height ... -
Survivability of ships at sea: A proposed model to account for human factors in a safety critical system
(Journal article, 2014)Most serious accidents at sea are caused by minor incidents that escalated into an uncontrolled situation. This study is aiming to develop a model to investigate the likelihood of fatal accidents, given that a critical ... -
Motion Compensation System for a Free Floating Surface Effect Ship
(Chapter, 2014)This paper deals with vertical motion compensation, or motion damping, on a freefloating Surface Effect Ship (SES) at zero speed. The Motion Compensation System (MCS) works by varying the air cushion pressure of a Surface ... -
Response and Structural Analysis of a Flap-type Wave Energy Converter in a Combined Wind and Wave Concept
