Wave conditions encountered by ships—A report from a larger shipping company based on ERA5
(Peer reviewed; Journal article, 2021)This study reports about the wave conditions encountered by the fleet of Maersk Line. Herein, wave conditions refer to integral wave parameters in terms of significant wave height, zero-upcrossing period, and wave direction ... -
Wave Conditions for Offshore Wind Turbine Foundations in Intermediate Water Depths
(Master thesis, 2012)In this thesis, the effects on regular waves when propagating from deep to shallow water have been investigated, assuming linear wave theory. The effects of shoaling, refraction, reflection and diffraction have been studied. ... -
Wave dispersion in moderate channel turbulence
(Peer reviewed; Journal article, 2023)We study channel turbulence by interpreting its vorticity as a random sea of ocean wave packet analogues. In particular, we investigate the ocean-like properties of vortical packets applying stochastic methods developed ... -
Wave disturbance rejection for monopile offshore wind turbines
(Journal article; Peer reviewed, 2019)The dimensions of offshore wind turbine (OWT) support structures are governed by fatigue considerations. For 6‐ to 10‐MW OWTs, wave loads are often dominating in terms of fatigue utilization. The present work proposes a ... -
Wave environment assessment at a Norwegian harbor for land-based aquaculture facilities using a combined numerical approach
(Master thesis, 2021)Numerical wave modeling of Norwegian coastal areas is challenging due to the strongly varying bathymetry, irregular coastline, and large domains of interest. Phase-averaged models provide an appealing solution due to their ... -
Wave Impact Forces on complex structures during lowering through the splash zone
(Master thesis, 2013)New oilfields are discovered further from land, at great depths and in harsh environments. Subsea developments of such fields are economical and preferred choice for operators today. One of the challenges is to process the ... -
Wave induced effects on floaters of aquaculture plants
(Doctoral Theses at NTNU, 1503-8181; 2010:20, Doctoral thesis, 2010)The main objective of this work is to study wave loads on floaters of fish farms. Several incidents of major fish escapes due to structural collapse of fish farms in harsh weather have motivated this study, as a step towards ... -

Wave induced motions of two ships advancing on parallel course
(Doktoravhandlinger ved NTNU, 1503-8181; 64, Doctoral thesis, 2002)Under way replenishment between two ships is a critical operation, and accidents have been reported. Hydrodynamic interaction between the hulls may influence the forces and the motions of the vessels, and both manoeuvring ... -
Wave inhomogeneities in a wave basin of constant water depth
(Journal article; Peer reviewed, 2023)Experimental testing of large marine structures in hydrodynamic laboratories requires an accurate reproduction of waves over a large area of the basin. However, with a uniform motion of the wavemaker, wave interactions ... -
Wave load compensation in DP control systems
(Master thesis, 2022)Denne masteroppgaven presenterer alternative metoder for bølgelastkompensasjon i dynamiske posisjonering (DP) av marine fartøy, der stabile og robuste konvensjonelle kontrollere med tilbakekopling vanligvis brukes. Slike ... -
Wave load effect analysis of a floating bridge in a fjord considering inhomogeneous wave conditions
(Journal article; Peer reviewed, 2018)When designing a floating bridge crossing a deep and wide fjord, a homogeneous wave field is usually assumed for simplicity. However, waves in fjords are commonly inhomogeneous, and hence the mentioned design practice ... -
Wave loads on decks of offshore structures in random seas
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:163, Doctoral thesis, 2012) -
Wave Loads on Underwater Protection Covers
(Master thesis, 2011)Submerged structures in shallow water can be exposed to large hydrodynamic wave- and current forces. An estimate of the total external loads will be important for the design and robustness of the structures. The aim will ... -
Wave power statistics for sea states based on wind statistics
(Journal article; Peer reviewed, 2018)The paper addresses how the wave power for sea states can be assessed based on available wind statistics for an ocean area. Results using a simple analytical tool are exemplified for a Pierson–Moskowitz wave spectrum ... -
Wave propagation in multicomponent flow models
(Journal article; Peer reviewed, 2010)We consider systems of hyperbolic balance laws governing flows of an arbitrary number of components equipped with general equations of state. The components are assumed to be immiscible. We compare two such models: one in ... -
Wave propagation over rugged topography Mehamn Harbourentrance case study

Wave Propulsion of Ships
(Doctoral thesis at NTNU;2015:16, Doctoral thesis, 2015)Propelling a boat forward by converting wave energy into propulsive thrust was first proposed in 1858 and first successfully done in practice in the 1890s - to the author's knowledge. Several experimenters have since ... -
Wave Response Experiments of Fish Farms
(Master thesis, 2023)Den globale havbruksnæringen er i en fase med store expansjon. Bærekraftig vekst i havbrukssektoren er en flott mulighet til å sikre sunn mat for mange. Det krever strenge regler og forskrifter, som drar nytte av omfattende ...
