Ship hulls exposed to ice-induced loads and resistance
(Master thesis, 2018)Marine activities in the Arctic have always been difficult. In recent year there have been a significant increase in activities in this region. This is a combined result of both global warming and a strong development in ... -
Ship Machinery Configuration Analysis - An Open Source Web-based Simulation Environment
(Master thesis, 2020)In the conceptual design phase of a ship, some of the parameters of the ship are required to be estimated to allow engineers proceed to other stages of the design . A ship is a complex structure which can be divided into ... -
Ship maneuvering model optimization for improved identification with less excitation
(Peer reviewed; Journal article, 2023)The precise model of a ship is the foundation for its operation and control. The traditional methods of building such models are time-consuming and require large amounts of simulation data, sea trial experiments, or ... -
Ship Motion Control Concepts Considering Actuator Constraints
(Master thesis, 2018)Numerous motion controllers and autopilots have been proposed over the years. Most control algorithms found in the literature do not explicitly consider saturation constraints for the actuators. In traditional control ... -
Ship motion-based wave estimation using a spectral residual-calculation
(Chapter, 2018)This paper presents a study focused on a newly developed procedure for wave spectrum estimation using wave-induced motion recordings from a ship. The particular procedure stands out from other existing, similar ship ... -

Ship Organizer
(Bachelor thesis, 2022)Giske Kystfiske var på utkikk etter en måte å forenkle lagerstyringssystemet deres på. Etter å ha opplevd vanskeligheter med sitt nåværende system, ønsket Giske Kystfiske at noen skulle utvikle en løsning tilpasset deres ... -
Ship Path Planning using Navigational Charts with Time-Dependent Weather Constraints
(Master thesis, 2018)Automatically planning safe paths for ships to follow will be an important step towards a more autonomous shipping industry. This thesis develops an algorithm that generates safe paths that avoid grounding, sailing in ... -
Ship Performance Monitoring using In-service Measurements and Big Data Analysis Methods
(Doctoral theses at NTNU;2022:101, Doctoral thesis, 2022)Ship performance monitoring is quite important for ship owners as well as charter parties to optimize their profits. Moreover, the regulatory organizations, like IMO, has also become interested here in order to maintain ... -
Ship Project Supply Chain Planning
(Master thesis, 2011)Shipbuilding is a project and customer driven industry with complex processes. The shipbuilding market is dependent on many other markets, such as world trade, world energy demand, demand for infrastructural development, ... -
Ship Propulsion Dynamics and Emissions Gas Engine Methane Slip Reduction at Dynamic Loads
(Doctoral theses at NTNU;2021:261, Doctoral thesis, 2021)Continuous discharging of greenhouse gases into the atmosphere has motivated researchers to develop prime movers for working with less polluted energy sources. The low cost of natural gas relative to diesel and gasoline ... -
Ship response and manoeuvrability - Main machinery characteristics, configuration modes, and its resulting effect on thrust response. Proposed dynamic ship merit factor / index.
(Master thesis, 2016)This thesis have in general been divided into three parts: Discussion about the traditional approach for station keeping and manoeuvring capability (static approach with dynamic factor), use of more modern tools analysing ... -
Ship routing and scheduling with speed optimization and voyage separation requirements
(Doctoral theses at NTNU;2017:43, Doctoral thesis, 2017)Summary of the thesis This PhD thesis discusses how operations research (OR) can be used to help ship operators with finding good solution for their tactical planning problems. The research has been a part of the larger ... -
Ship track estimation from single hydrophone data
(Master thesis, 2014)Passive acoustic range estimation and source tracking using hydrophones have been a problem because of the complexity of the underwater channel. This thesis is concerned with a fast method for the estimation of ship velocity ... -
Ship Tracking Based on Fiber Optic Cable Data
(Master thesis, 2020)På havbotnen rundt om i verda finns det eit nettverk av fiberoptiske kablar. Ved å kombinera desse kablane med ein teknologi kalla distribuert akustisk måling, kan det kanskje vera mogleg å bruka data frå kablane til å ... -
Ship Traffic Organization with Moving Havens: Ship and Shore Perspective
(Chapter, 2020)e-Navigation is a concept launched by the IMO in 2006. The point is to share digital data to the benefit of safety, efficiency and the environment. Every ship must make a voyage plan before leaving berth. Sharing such ... -
Ship Traffic Scheduling and Disruption Management for the Kiel Canal - A Simulation-Optimization Approach
(Master thesis, 2018)The Kiel Canal is a nearly 100 km long artificial waterway that connects the North Sea and the Baltic Sea through the north of Germany. The canal alternates between wide and narrow segments, and on the narrow segments the ... -
Ship Trajectory Control Optimization in Anti-collision Maneuvering
