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 light of the recent increasing interest in the oil and gas developments in the arctic region, Huisman Equipment B.V. started development of a drilling semi-submersible suited for arctic condition. Model tests were performed by the Krylov Shipbuilding Research Institute to gain insight in the ice forces acting on the structure. Based upon the...

A model has been developed to calculate extreme responses of turret moored ships. The responses are expressed in terms of the environmental parameters: waves wind and current. Motions in the horizontal plane, surge, sway and yaw, are analyzed statically and dynamically. The static analysis resolves the equilibrium position and heading about...

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 costs of wind energy have to be reduced in order to be competitive with conventional methods to generate electricity. The tower costs contribute significantly to the costs of a wind turbine. This thesis aimed to suggest improvements in wind turbine tower design in comparison with industry standards nowadays in order to reduce the costs of...

A large contribution to the overall project costs of an offshore wind farm originates from the transport and installation of the substructures. A better understanding of the operational limits that apply for the installation helps to improve the project execution and thus reduces costs. It is important to analyze in which sea states the...

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...

This thesis presents the comparative study of the three different dynamic analysis methods (quasi-static, frequency-domain, time-domain), with respect to the dynamic analysis of the Yme MOPUstor platform. The initiation of this thesis is Allseas engineering project. As a major contractor in the oil and gas industry, Allseas group is seeking a...

The first report is about: A jack-up rig is a mobile offshore platform. Basically, it is a self-elevating pontoon, which can be supported by retractable legs resting on the sea bed. Recently, it is proposed to use these platforms for production of marginal fields, what implies a longer term use. Furthermore, there are plans to use such platforms...

A guyed tower offshore windmill has been designed to utilize the much higher wind energy production possible there in comparison to onshore. It will be sited in an intermediate water depth (=75 m) of a coastal region. The feasibility for North Sea conditions for a structure with a life of 25 years has been examined. A modified design, slender...

Over the last decades the costs of drilling oil and gas wells have soared. One of the ways to reduce drilling costs is to drill the wells at a faster rate. This can be done by changing operational parameters, like the rotational velocity of the drill string or the weight on the bit. However, increasing these parameters can lead to violent...

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....

First, the focus of a literature review was on industry visions and fatigue life assessments. Hence fatigue analysis methodology —with a special focus on local modelling— was thoroughly investigated because this is the Shell and industry accepted method to define and assess fatigue life. Secondly, a new strategy was developed to stretch the...

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...

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...

Wind energy needs to become cheaper in order to take on the competition with current non-durable energy sources. Innovative design procedures and better understanding of structural behavior are aimed for to improve the current wind turbine design. A better understanding of turbine behavior consists of several fields and one of these fields is...
