Stability Analysis of a Rapid Mechanical Lifting System for the Vertical Transportation of Polymetallic Nodules

Due to urbanization, improved living standards and electrification, approximately five times more raw minerals are necessary in 2050 compared to 2018. In deep oceans, the seafloor contains these minerals in the form of polymetallic nodules. Nodules are about the size of golf balls that grow throughout the ocean at depths between 3500 m and 6000...

Dynamic Load Prediction in Offshore Wind Turbines

The rapid development of the wind industry over the past few years has pushed turbine manufacturers to meet the growing energy demands by designing and producing large scale wind turbines.This also means development of larger monopile foundations for the foundation designers in the case of offshore wind turbines.\ Generally, the turbine tower...

Improvement of the operating reliability of the BAM Tidal Bridge by reducing the dynamic response due to waves

The BAM Tidal Bridge is a proposed bifunctional concept of a bridge connection between two Indonesian islands, and the world’s largest tidal power plant. The wave forcing on the floating structure leads to an undesired dynamic response and a decreased operating reliability. The thesis objective is about designing an additional structure or a...

Two-dimensional ice-structure interaction for offshore wind turbines

With the Paris climate accords signed in 2016, most countries have committed themselves to ambitious climate targets during the next decades. One of these targets is a dramatic increase in the overall energy portfolio's market share of renewable energies. This increase in renewable market share will, for a large part, consist of newly built...

Experimental setup of the dry test for Gyroscopic-pendulum wave energy converter

Oceans account for 71 percent of the earth’s surface, marine resources and energy are abundant. Therefore, making full use of marine energy is a good choice for humans to solve the energy crisis. One way to capture ocean energy is converting wave energy to electrical energy, by means of devices called wave energy converters (WECs). This project...

Power Efficiency of the Gyroscopic-Pendulum Wave Energy Converter

The oceans, which cover nearly 70% of the earth’s surface, can be considered as an inexhaustible energy source for renewable electricity due to its size and predictability. One way to capture ocean energy is by harnessing the energy produced by waves at sea, by means of devices called wave energy converters (WECs).<br/><br/>Delft University of...

Work-ability increase: Using tugger control

For the offshore market an increase in renewable projects can be observed. The technological innovations are continuously decreasing the costs of renewable projects. Especially offshore wind is getting more cost effective, and is receiving a lot of attention. However, with the growth of the sector, new challenges arise. Water depths are...

Technical feasibility study for slurry transport of the Atlantis II deep-sea mining field

Deep-sea mining is becoming more popular. The Atlantis II Deep is a deep sea mining field of metalliferous muds in the Red Sea. This field could be exploited by transporting the sediments through a pipeline laid from shore onto the sea bed to the field. From determined concentrations with their shear stress-shear rate relation, parameters for...

Dynamic FEM assessment of sagbend: Improved methodology for the dynamic FEM assessment

Deep-sea nodule mining: Vertical transportation of collected manganese nodules by means of mechanical lifting

With a rapidly growing population and subsequent technological developments, an increase in demand of rare-earth metals evolves. Land-based deposits seem to be insufficient and shortage impends within the coming decades. Mineral resources from the deep ocean are considered as a possible complement. These minerals occur in various forms. One of...
