Offshore wind turbines are being placed all over the world. The increased popularity of these structures comes with a boost to the development of wind turbines in general, resulting in larger and higher constructions. To ensure the support structures of the turbines are able to withstand the extreme loads and environmental conditions, it is...

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

Several calculation models have been developed to predict the cutting forces in the linear rock cutting process. Rock failure can occur in different manners: brittle tensile, brittle shear and ductile. Each failure mechanism has a corresponding calculation model with specific cutting geometries and assumptions to predict the cutting forces as...

Shipyards these days see an increase in customers that specify combined speed and seakeeping ability design requirements. This requires the shipyard to make a prediction of the additional installed power required to maintain a certain speed when waves are encountered. The additional required installed power is directly related to the average...

Over 450 oil platforms need to be removed from the North Sea in the next decade. Each of these platforms is custom designed for installation and service lifetime, but not for decommissioning. Allseas' Pioneering Spirit is the largest heavy lift vessel in the world, capable of lifting complete topsides in a single-lift operation. The vessel’s...

In the field of fatigue testing in laboratory conditions, the common practice is uniaxial testing (i.e. in tension). The real-life loads on structures are usually not limited to one direction but contain multiaxial components. For this kind of testing, the ship and offshore structures department of Delft University of Technology developed a...

This master thesis describes a method to determine the workability of an offshore heavy lift operation. By creating wave realisations based on and statistically equivalent to measured ocean weather data, a quick assessment of the risk of failure can be achieved.

In the past decades the understanding of fracture of ductile material has increased substantially. Research has shown that the onset of fracture highly depends on the full state of stress inside the material. Better understanding of fracture resulted in more advanced and complex fracture models being conceived, allowing researchers to predict...

In order to guarantee safe operations in the offshore industry, at all time it is necessary to predict motion behaviour of structures in specific sea states accurately. Safety is very important for the offshore industry, which can come in jeopardy when motions are either extreme or unexpected with regards to predicted motion behaviour. This...

During Abandonment and Recovery (A&R) operations, steel wire ropes (figure 1) can experience torsional deformation. This deformation is a result of the helical configuration and the tension gradient in the rope due to its self-weight. The latter is very high when the ropes are used in deep water operations. Since the static component of the...

In order to meet future energy demand, a more sustainable energy society is essential because fossil fuel reserves are depleting while the total energy consumption worldwide increases. One type of renewable energy which can play a role is ocean energy having the theoretical potential to exceed both current and future human energy needs. This...

The Pioneering Spirit is the world’s largest construction vessel. The twin-hulled vessel is 382 m long and 124 m wide. At the bow is a slot, 122 m long and 59 m wide, that enables the Pioneering Spirit to straddle a platform and remove or install entire topsides up to 48,000 t in a single lift using eight sets of horizontal lifting beams. Until...

In a world with an increasing energy demand and consciousness of the long-term effects of the use of fossil fuels, offshore industries are continuously searching for new sources of energy. Marine tidal currents, which are a consequence of the gravitational forces exerted by the Moon and the rotation of the Earth, have a theoretical potential up...

The present state-of-the-art modelling tools (such as FAST, BLADED) used for modelling an offshore wind turbine (OWT) are too detailed and computationally expensive. These tools are required only at detailed design stages of a project. For the preliminary phase, however, a much simpler (yet reliable) 3D model can improve and speedup the design...

Declining production, continuously rising cost levels, low oil prices and the subsequent declining reserves, are forcing the oil and gas industry to reduce its operating expenditures. This study focuses on how the best maintenance policies for the power generation on unmanned satellite gas platforms of Total Exploration and Production...

For decades, sub-sea pile driving has been performed to safely attach offshore and sub-sea infrastructure such as jackets, templates and manifolds to the supporting soil. In sub-sea pile driving, a hammer is lowered from an installation vessel and similarly descended until the (generally steel tubular) pile reaches his final penetration depth....

A significant reduction in the levelized cost of electricity is necessary for offshore wind farms to become a competitive energy source. Amongst other methods, overall project cost reduction can be achieved by optimized support structure design. An upcoming trend is the use of `XL monopiles', which provide a cost effective foundation solution...
