In current offshore wind turbine (WTG) tower installations, bolted flange connections are common. These connections are however reaching their limit due to the maximized size of the bolts. Also, bolted connections require the motions between the tower and foundation to be limited during installation, suggesting their workability of installation...

In order to meet the climate goals to minimize the global temperature rise, an accelerated growth of renewable energy sources is necessary. Within the renewables market, the offshore wind sector takes a big part and has experienced a rapid growth over the past years. Around 80% of offshore wind turbines have a monopile foundation, (a large...

The offshore wind energy industry has been developing rapidly due to the increasing demand for renewable energy. As a result, offshore wind turbines are increasing in mass and height and are installed at larger water depths and further away from shore. A floating vessel is not limited by water depth and soil conditions, but is sensitive to wave...

Wind turbine industry is growing and future predictions are promising. However, a shortage of installation vessels could influence this growth in offshore wind industry. Commonly, wind turbines are installed in components using a jack-up vessel. Occasionally, wind turbines are installed fully assembled. The center of gravity of a fully assembled...

Ocean thermal energy conversion (OTEC), is a renewable energy resource that uses the thermal gradient of the ocean to generate electricity. Warm surface water and cold deep sea water, which can be found at depths of approximately 1000 [m], are used to generate electricity in a thermodynamic Rankine cycle. Due to its dimensions, the installation...

As the exploration for oil and gas is shifting towards greater water depths, there is a market for subsea rock installation (SRI) at these large water depths as well. Boskalis is a key player in the rock installation market and installing rock material at water depths of approximately 3000 meters is still far from routine work. Therefore,...

To decrease Europe’s harmful emissions, the European Union aims to substantially increase its offshore wind energy capacity. To further develop offshore wind energy, investment in ever-larger construction vessels is necessary. Designing these vessels is difficult however, as this market is characterised by a large but seemingly unpredictable...

The yearly installed percentage of offshore wind jacket substructures is rising. The most common installation method for a jacket structure nowadays starts by driving the foundation piles in the seabed through a pre-piling template. The jacket is then lowered on top until the legs are resting on the foundation piles through friction-based...

Over the last decade, the demand for offshore power cables has increased significantly due to, in particularly, the emergence of offshore wind. Despite this growth, industry-wide rules and guidelines to analyse fatigue during cable installation operations are yet to be developed, even though fatigue can become an important...

This graduation project follows the process of researching, developing and creating a demonstrator for a surface design using the electroluminescent material - EL for short - a sandwich structured composite that emits light when alternating current flows through it. The project kicks-off with an analysis phase where the electroluminescent...

The Nederlands Fotomuseum is the Dutch national museum for photography and its archive has the biggest collection of photographic material in the country. Currently, the visitors of the museum have a rather passive role and are merely subjected to the visual artworks in the museum. The museum desires to give the visitors more insight in the...

During the design phase of a foundation installation aspects are easily overlooked. When this aspect is overlooked a foundation element risks not reaching its design depth or getting damaged during the installation process. As a result significant delays and/or costs could occur. A driveability study gives insight in the installation aspects of...

With increasing diameters of offshore monopile foundations, impact hammers require more energy per blow in order to drive them into the seabed. This does not only increase the fatigue loading on the monopile, but it also increases underwater noise that affects marine life. The increase in installation costs due to additional material on the...

Offshore wind energy is one of the solutions to meet the growing demand for renewable energy. The offshore wind turbines producing this energy keep increasing in size and, as a result, the monopile foundations are becoming larger and heavier. The traditional jack-up installation vessels have limited crane capacity and many of these vessels are...

To reach the Paris Agreement goals, switching from fossil fuels to renewable energy is inevitable. Wind power has proved to play a critical role in this transition. To speed up this transition, the wind industry must keep innovating. The major part of Wind Turbine Generators (WTGs) is installed by a jack-up which not only has its limitations...

In 2022 the first 12 MW offshore wind turbines are expected to be installed. Due to the continuous upscaling of wind turbine generators new problems are expected to arise during the installation of the turbines. Especially the workability of the installation of larger wind turbine blades, which are already causing problems during the...

The energy transition results in large offshore windfarms being installed. The most common support structure for a wind turbine at sea is a monopile. These are currently installed by large hydraulic hammers. However, hammering produces a lot of underwater noise which may harm marine life (Kastelein, 2014). Therefore, the industry is looking for...

Today’s increasing complexity, rising interconnectivity and larger systems in engineering require new approaches and methods for effective engineering. This is also the case for the technological installation in infrastructure sector (TII), which designs technical systems for infrastructural civil structures. To assist in engineering, Model...

Contrary to a one-off jacket installation where a contractor can wait for favourable weather conditions, the installation of support structures for offshore wind turbines is of repetitive nature. This repetitive nature leads to a need for a better understanding of the behaviour during installation of various jacket geometries. This need brings...

Due to often existing subsea infrastructure or challenging seabed conditions, engineers are forced to design newnearshore pipeline trajectories that are not always in a straight line. Since subsea tie-in operations are often complex and relatively expensive, alternative methods like pulling pipelines into a curve are worthwhile. By means of this...
