The ongoing transition towards sustainable energy has resulted in a large interest in alternative sources. Proton exchange membrane fuel cells (PEMFC) use hydrogen to produce energy without harmful emissions, and they can be used in a range of applications, from mobility to industrial power generation.<br/><br/>One hurdle that still stands...

The Autonomous Low Energy Replenishment Dredger (ALERD) strives to revolutionize the dredging world. The ALERD operates autonomously underwater, which saves energy during the dredging process and transit. Autonomous underwater operation drives the need of alternative energy facilities. However, due to the energy savings of dredging, alternative...

The Ampelmann A-type hexapod platform is a motion compensating gangway system designed to transfer offshore personnel between a crew transfer ship and an offshore bottom founded structure. During operation, the platform is moved to compensate wave induced ship motion and create a still standing platform from which crew can safely transfer to the...

Current dynamical models of the slewing motion of offshore cranes cannot predict the occurring vibrations during the design phase that arise during slewing. The relatively small pedestal crane on the Sleipnir experienced severe vibrations during the slewing motion in both the crane house and the boom, which were in the order of 1 and 5 Hz. As a...

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...

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...

Raising environmental concerns have stimulated the development of renewable energy, including energy from the oceans, which contain a huge potential. In this thesis, particular emphasis is given to wave energy, which can deliver up to 2 TW on a global scale. The aim of this thesis is to optimize the control system of the Symphony Wave Power...

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. <br/>If there is a coil wound around...

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...

One potential problem associated with the high electrical frequency in high-speed electrical machines are additional iron losses near the end-windings. They are expected to be a significant part of the total iron loss. The reader is introduced to currently known methods to study high-frequency iron loss estimation and end-effects in laminated...

Wind energy has recently come to constitute more than 10% of the electric power consumed in the EU. As the wind industry is rapidly growing, wind turbines grow larger and new models are soon expected to reach ratings of 10 MW. The development of offshore wind farms is another major trend in the industry. Offshore farms are particularly suitable...

The global demand for natural gas is growing as gas is a cleaner partner to renewable energy than oil and coal. To be able to exploit remote offshore gas fields Shell is developing a floating facility to produce, treat and liquefy natural gas, called a Floating Liquid Natural Gas (FLNG) vessel. To make the FLNG vessel a cost effective option for...

The extension of the reliability and hence the lifetime of the power converters used in wind turbine systems gains growing interest given the potential to drive the costs further down. This study conducts a detailed comparison among several suggested multilevel converter topologies so as to investigate which converters achieve a more even...

As we move deeper into offshore waters to harness more of wind energy there is a need to keep the total operational and maintenance costs to a minimum, of which expenditures related to the generators form a major share. Brushless Doubly-fed Induction machine used as a generator, due to the requirement of a lower rating converter, and the absence...
