Water separation from wellstream in inclined separation tube with distributed tapping
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:222, Doctoral thesis, 2011)Water separation in an upward, inclined separation tube, with distributed tapping points has been studied, verified and modeled in this thesis. Phase segregation in an upward inclined pipe is widely occurring in oil and ... -
Water Vapour Resistance of Ceiling Paints - Implications for the Use of Smart Vapour Barriers in Compact Wooden Roofs
(Peer reviewed; Journal article, 2023)Smart vapour barriers enable building envelopes to dry toward the interior side. This property can be used in compact wooden roofs to create more slender structures by placing the wooden load-bearing elements inside the ... -
Water waves in the presence of sub-surface shear: developing an experiment
(Master thesis, 2016)The planning and analysis of a laboratory set-up for examining the behaviour of water waves in the presence of sub-surface shear is presented in the following work. Water waves propagate on shear currents in many important ... -
Water-repellent surfaces consisting of nanowires on micro-pyramidal structures
(Journal article; Peer reviewed, 2019)Super-repellent surfaces are relevant for several practical applications, such as water collection and self-cleaning and anti-icing surfaces. However, designing surfaces that can maintain their super-repellency when the ... -

Waterflooding Optimization for Improved Reservoir Management
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:56, Doctoral thesis, 2012) -
WaterMet2: a tool for integrated analysis of sustainability-based performance of urban water systems
(Journal article; Peer reviewed, 2014)This paper presents the “WaterMet2 ” model for long-term assessment of urban water system (UWS) performance which will be used for strategic planning of the integrated UWS. WaterMet2 quantifies the principal water-related ... -
Waterproof sprayed concrete with improved sustainability performance
(Chapter, 2023)Sprayed concrete in combination with rock bolts has successfully been used for permanent rock support in tunnels for decades. The main shortcoming is that sprayed concrete alone is unable to function as permanent waterproofing ... -
Watertight insertion of heavy sliding doors in exterior walls
(Peer reviewed; Journal article, 2023)The joints around heavy terrace doors are considered a weak point in rain-exposed façades, as it is vulnerable to defects in design and construction. The insertion process of heavy sliding doors is a notable challenge. ... -
Wave and Current Effects on Floating Fish Farms
(Journal article; Peer reviewed, 2018)The paper is partly a review on hydrodynamic and structural aspects of fish farms. In addition, new numerical results are presented on the stochastic behavior of bending stresses in the floater of a realistic net cage in ... -
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 ...
