The modeling method for the performance of positive displacement pumps of hydraulic pumps is based on collecting operational data of the pump for its operational envelope and using equations with empirical fitting parameters and fit these equations to the data. This way values for the fitting parameters are obtained, with which the equations can...

Subsea pipelines are critical for oil and gas production and transport, more than 100.000kmof subsea pipelines have been laid. These pipelines are laid by specially designed ships which can lay these pipelines at great depth and a high speed. However, designing the supply chain to deliver joints (pipe pieces) to these pipe lay vessels can be...

Artificial intelligence is used in this research to predict the shelf life of strawberries. The prediction of shelf life is based on temperature measurements from the moment a package of strawberries is harvested till the moment this same package is bought by a customer in a local PLUS supermarket. The strawberries are harvested in the south of...

This work simulates the impact of horizontal motion on the Symphony wave power device. To that end the existing time domain simulation is expanded with a module that simulates horizontal motion in the 2d plane. This extension is coupled with the existing operational modelling. the extension is based on a mathematical motion model based on rigid...

As wind turbines continue to increase in size, so do the loads acting on the drivetrain.
To handle the higher loads the mass of the drivetrain needs to increase. A better understanding
of this mass increase can result in lighter drivetrain design and provide
an insight which drivetrain design has the lowest mass potential for large...

Wind energy plays a major role in the ongoing energy transition. To accelerate the adoption of wind energy and thereby the energy transition, the Levelized Cost of Energy (LCOE) has to be minimized. Apart from increasing turbine performance, reducing turbine down-time can contribute to lowering the LCOE.Down-time is defined as time during which...

In the transition to renewable energy, harvesting the power from oceanic waves is often mentioned to be next step after the deployment of wind energy technology. Although many different solutions for wave energy conversion (WEC) are being developed and financial support schemes exist, commercially extracting this energy seems however to be...

Converters are the essential devices in the energy transformation process from the wind generators to the grid. Power electronic semiconductors have a high share of failures in the power electronic converters. Therefore, the reliability based on lifetime of power semiconductor generates more and more attention. This thesis presents a comparison...

Stability and security of the grid are two vital aspects of energy supply. To keep the grid stable, it is necessary that the electricity plant can control and protect the mechanism. In the past, traditional plants could meet these requirements. Nowadays, the share of sustainable power sources in total electricity generation has become so...

Eddy currents are loops of electrical currents induced within conductors by varying magnetic field in the conductor. Eddy currents flow in the closed loops in the conductor, in planes perpendicular to the magnetic field. The eddy current effect plays an important role in the transformer or an actuator system.
If there is a coil wound around...

Tidal energy is one of form through which renewable energy can be extracted from oceans which covers more than 70% of the earth surface. Tides are a periodic function and can be predicted for a long period this makes tidal energy more favorable than other ocean energy. To prevent the sealing problems associated with the tidal generators the...

Steam has been widely used in industrial processes, however, these industrial processes also discharge a huge amount of low quality waste steam, low temperature steam at ambient pressure which is not fit for heat integration with other local processes. As the energy needs and environmental concerns increase, it is desirable to utilize the waste...

Current trailers and caravans use overrun brakes, which cause overheated brakes in the mountains. A solution is to design an electric brake system in which the brakes are controlled electronically instead of mechanically. The report discusses the control models associated with braking, anti-sway detection and velocity sensor fusion. The RDW...
