Power train degradation modelling for multi-objective active power control of wind farms
(Journal article; Peer reviewed, 2023)With the coming installation of hundreds of GW of offshore wind power, penetration of the inherent power fluctuations into the electricity grid will become significant. Therefore, the use of wind farms as power reserve ... -
Prandtl steady rotary current in an upright cylindrical container
(Journal article; Peer reviewed, 2018)The quantifying of the experimentally-known (Prandtl, 1949) steady rotary current during the swirl-type sloshing is first given. The current is treated as the sum of the mean wave (pseudo-) momentum through the meridional ... -
Predicting rig motions on a MODU using operational data and machine learning
(Master thesis, 2019)Olje og Gass selskaper har investert store summer i infrastruktur til å samle, lagre og henteut data, noe som har ført til at enorme mengder med data blir generert og lagret hver dag.Denne dataen, i kombinasjon med utviklingen ... -
Predicting scour around offshore wind turbines using soft computing techniques - Comparing Genetic Programming with Existing Scour Prediction Methods.
(Master thesis, 2015)In this report a prediction method is developed for scour around monopiles. A soft computing technique called genetic programming (GP) is used to create a scour prediction formula that can compute scour in all offshore ... -
Predicting ship speeds in the Arctic using deep learning on historical AIS data
(Chapter, 2020)This study offers a perspective of applying fully connected neural networks (NN) to predict vessels’ speeds on a part of the Northern Sea Route and discusses its challenges. A fully connected neural network model was used ... -
Predicting Ship Turnaround Times with Machine Learning
(Master thesis, 2020)Målet med denne oppgaven er å undersøke hvorvidt maskinlæring ved hjelp av AIS, skips- og seilasdata kan brukes til å predikere hvor lang tid et skip vil bruke i havn. Undersøkelsen er gjort fra et havneperspektiv som betyr ... -
Predicting the Buckling Load of Stiffened Plates by Surrogate Modeling
(Master thesis, 2024)Denne masteroppgaven undersøker anvendelsen av surrogatmodeller, spesielt kunstige nevrale nettverk, til strukturanalyse av stive platepaneler, en vanlig komponent innen marin ingeniørkunst. Sammenlignet med tradisjonell ... -
Predicting the Heading Misalignment of a Vessel-Shaped Offshore Fish Farm Under Waves and Currents
(Chapter, 2018)A vessel-shaped fish farm concept for open sea applications has been proposed recently. The whole system consists of a vessel-shaped floater, fish cages positioned longitudinally along the floater, and a single-point mooring ... -
Predicting thrust loss of ship propellers due to ventilation and out-of-water effect
(Journal article; Peer reviewed, 2017)This paper presents a propeller ventilation model that is tuned on experiments performed in open water condition in a towing tank. The main purpose of performing the experiments was to obtain more data at higher advance ... -
Predicting vessel speed in the Arctic without knowing ice conditions using AIS data and decision trees
(Peer reviewed; Journal article, 2021)The vessel speed is one of the important parameters that govern safety, emergency, and transport planning in the Arctic. While previous studies have traditionally relied on physics-based simulations to predict vessel's ... -
Prediction of deepwater riser VIV with an improved time domain model including non-linear structural behavior
(Peer reviewed; Journal article, 2021)In this paper, vortex-induced vibrations (VIV) of deepwater risers including the VIV-induced tension fluctuations were simulated using a time domain VIV model. Data from a large-scale riser experiment was applied for ... -
Prediction of Design Response for North Sea
(Master thesis, 2010)The methods to predict long term extreme structure responses induced by environmental loads are reviewed. Due to the variability of both environmental condition and response in a given environmental condition, the prediction ... -
Prediction of DI-CI Engine Performance and Emission Characteristics of Varying Renewable Diesel Fuels with Experimental Results from Marine Diesel fuel
(Master thesis, 2011)This paper discusses finding of combustion research carried out using Ricardo hydra research diesel engine with varying renewable fuels. The primary fuel of investigation is rapeseed methyl ester (RME) and marine diesel ... -
Prediction of extreme loads and fatigue damage for a ship hull due to ice action
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:77, Doctoral thesis, 2013)Knowledge about statistical behavior of local ice loads on ship hulls is valuable for the purpose of safe voyage in ice-covered waters, both for short and long term time horizons. Based on the loads that are measured, e.g. ... -
