  1. 1. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martin Persson; [2022]
    Nyckelord :Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

    Sammanfattning : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. LÄS MER

  3. 2. Jordning av propelleraxel : Konceptutveckling för jordningsanordning som kräver lite underhåll

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :William Bergqvist; [2019]
    Nyckelord :Jordningsenhet propelleraxel; prestanda optimering; konceptgenerering; fiberborstar;

    Sammanfattning : Detta masterprojekt genomfördes på Rolls-Royce AB (nu känt som Kongsberg Maritime per 1 april 2019) i Kristinehamn, Sverige. Avhandlingen fokuserar på att utveckla en jordningsutrustning för propelleraxlar som kräver lågt underhåll till företagets nya poddrivna framdrivningssystem. LÄS MER

  4. 3. Estimation of Ship Properties for Energy Efficient Automation

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Lucas Nilsson; [2016]
    Nyckelord :System identification; ship properties; energy efficient; automation; ship modelling; estimation; signal processing; simulation; ship dynamics; cusum; cumulative summation; change in dynamics; load condition; podded propulsion; azipod; yaw dynamics; noise impact; measurement noise; model error; bias due to model error; ship yaw model; moment of inertia; estimate ship properties; ship automation;

    Sammanfattning : One method to increase efficiency, robustness and accuracy of automatic control, is to introduce mathematical models of the system in question to increase performance. With these models, it is possible to predict the behavior of the system, which enables control according to the predictions. LÄS MER
