Computational Fluid Dynamics Simulations of Nonlinear Sloshing in a Rotating Rectangular Tank Using the Level Set Method
(Journal article; Peer reviewed, 2018)In this paper, numerical simulations of nonlinear sloshing in rectangular tanks are presented. Model implementations in the open source software reef3d are tested, and the results are compared with experimental data from ... -
Computional fluid dynamics (CFD) study on free surface anti-roll tank and experimental validation
(Master thesis, 2015)The excessive motion of a ship can seriously degrade the performance of machinery and personnel. Anti-roll tanks are tanks fitted onto ships in order to improve their response to roll motion, which is typically the largest ... -
Concept Design and Simulation of a Water Proofing Modular Robot for Amphibious Locomotion
(Chapter, 2017)This paper will introduce a novel adaptive modular robot for amphibious locomotion research. First, an overview of modular robotic research is given systematically. In this project, we concentrate on designing a new kind ... -
Concept Development of a Sailing Cruise Ship Powered by Alternative Fuel
(Bachelor thesis, 2023)I denne oppgaven har et konsept for et miljøvennlig ekspedisjonscruiseskip blitt utviklet. Skipet tar i bruk metanol som alternativt drivstoff for å være CO2-nøytralt. Seil blir også brukt for å kunne redusere utslippene ... -
Conceptual design study of a harvesting tool for large-scale seaweed production on current kelp farms
(Master thesis, 2022)Tare er blitt et populært og mye diskutert tema de siste årene på grunn av dets mange ideelle egenskaper som plante og ressurs. Tare finnes i naturen eller kan dyrkes. Begge metoder praktiseres, men siden høsting av vill ... -
Containerisering av Nord-Norge
(Bachelor thesis, 2021)Siden containeren ble introdusert på 1960-tallet har bruken av den eksplodert. Samtidig ser man at bruken av den i deler av Nord-Norge ikke er like utbredt. Denne oppgaven undersøker derfor følgende problemstillingen: ... -
Containerisering av Nord-Norge
(Bachelor thesis, 2023)Containertransporten har revolusjonert den globale handelen ved å tilby effektive løsninger for frakt av varer. I midlertidig ser man at containertransport ikke har blitt like utbredt i deler av Nord-Norge, og transport ... -
The contribution of Vessel Traffic Services to safe coexistence between automated and conventional vessels
(Peer reviewed; Journal article, 2021)The maritime industry could face major changes the coming decade. Technology development opens for new ways of operating vessels and autonomy is argued to revolutionise design and operations. However, despite a large focus ... -
Contribution of Wastewater Irrigation to Soil Transmitted Helminths Infection among Vegetable Farmers in Kumasi, Ghana
(Peer reviewed; Journal article, 2016)Wastewater irrigation is associated with several benefits but can also lead to significant health risks. The health risk for contracting infections from Soil Transmitted Helminths (STHs) among farmers has mainly been ... -
Control of the combustion process and emission formation in marine gas engines
(Journal article; Peer reviewed, 2018)A smooth transition to the use of gas engines instead of conventional engines in marine shipping is a logical pathway for compliance with tightening environmental regulations. Currently, five major gas engine concepts are ... -
Controlling Kuka Industrial Robots : Flexible Communication Interface JOpenShowVar.
(Journal article, 2015)JOpenShowVar is a Java open-source cross-platform communication interface to Kuka industrial robots. This novel interface allows for read-write use of the controlled manipulator variables and data structures. JOpenShowVar, ... -
Conversational user interfaces for maritime autonomous surface ships
(Peer reviewed; Journal article, 2024)We propose integrating conversational user interfaces (CUIs) into Maritime Autonomous Surface Ships (MASS) to facilitate direct communication with other ships without human intervention. The aim is to enable other ships ... -

Coupling of dynamic reaction forces of a heavy load crane and ship motion responses in waves
(Peer reviewed; Journal article, 2021)The conventional approach to dynamic analysis of ship motion response with shipboard operation equipment is usually done by establishing combined equations of motion of the multi-body system. The weakness of such methods ... -
Creating and Processing Ship Design Data for Sheet Metal Cutting.
(Master thesis, 2016)The process from the creation of a design to the initiation of production in the shipbuilding industry is a complex procedure. Recently more and more shipyards has started moving away from traditional shipbuilding methods. ... -
A Cross-Modal Integrated Sensor Fusion System for Fatigue and Awareness Assessment in Demanding Marine Operations
(Doctoral theses at NTNU;2021:34, Doctoral thesis, 2021)The maritime domain is characterized by demanding operations. These operations can be especially complex and dangerous when they require coordination between different maritime vessels and several maritime operators. ... -
Cryptanalysis of a generic one-round key exchange protocol with strong security
(Journal article, 2017)In Public-Key Cryptography (PKC) 2015, Bergsma et al. introduced an interesting one-round key exchange protocol (which will be referred to as BJS scheme) with strong security in particular for perfect forward secrecy (PFS). ... -
