Modelling of Floating Offshore Wind Turbines (FOWTs) is challenging due to the strong coupling between the aerodynamics of the turbine and the hydrodynamics of the floating structure, which makes the dynamic response of the whole system highly complex. A variety of numerical approaches can be used to predict this response.<br/><br/>The frequency...

Operational optimization of vessels is valuable for the planning and execution of maritime operations. Accurate and efficient models to predict vessel motions are needed to make reliable operational decisions. The wave-induced vessel response can be modelled in terms of a Response Amplitude Operator (RAO) and a wave spectrum. Uncertainties...

Deterministic predictions of wave induced ship motion are increasingly often used to enlarge the oper- ational envelope of ships that perform complex operations at open sea. The large amount of complex operations performed nowadays, motivates the relevance of motion predictions. The company Next Ocean provides these forecasts, based on linear...

\chapter*{Abstract}<br/>Larger wind turbines are being developed to fill the growing demand for green energy. Wind turbines that need to be installed in the next decade will reach a capacity of 15 MW, with an approximate rotor diameter of 240 meters. The currently used wind turbine installation vessels cannot install these larger wind turbines;...

In offshore operations a trend is forming where vessels are more often required to do multiple short operations within a small-time frame. Traditional mooring systems require execution time far beyond the operation time. Dynamic positioning systems offer great advantages for short time span operations such as crew transfer or lift operations. ...

Within this thesis an attempt is made to improve the seakeeping of a Service Operation Vessel (SOV) by means of an active anti-roll tank (ART). It is researched if the addition of a wave prediction system can improve the ART’s performance. As the seakeeping of the SOV is most important for the installed motion compensated gangway, the...

Real-time ship motion predictions contributes to safer operations at sea and increases workability. Nowadays, a handful of people and companies are actively working on this subject. Most approaches use the ship’s navigational radar to first predict the wavefield surrounding the vessel and then calculate the motion response. One of the methods...

New floating wind turbine designs are needed to reduce production costs and to increase mass production feasibility. The TetraSpar floating wind turbine achieves these goals by being constructed using components highly suitable for standardization and industrialization. The design makes use of a suspended submerged counter weight to obtain a low...

Experience-based decision making by crew plays a key role in the safe and effective execution of maritime operations. For yachts and naval vessels, common operations can be identified as helicopter operations (take-off and landing), launch and recovery of small craft and (dis)embarkment to and from these small craft. All of these operations are...

Heerema Marine Contractors is constructing a new semi-submersible crane vessel, the Sleipnir. Due to low initial stability, semi-submersibles may present significant wave induced resonant motions in heave, roll and pitch. For practical reasons, especially the roll motion could play a limiting factor for future lift operations of the Sleipnir. In...

Floating Bulk Transhipment Operation (FBTO), as a link in the whole bulk logistic chain, used to be performed only in well-sheltered water. Current operability assessment of FBTO is mainly based on experience and rules of thumbs, only taking into account environmental conditions such as significant wave height and wind speed. Corresponding to...

Humans have been using ships to transport goods and people around the globe for hundreds and thousands of years. In all cases harbours have been critical for the exchange of goods and have played a significant role in the development of countries. Initially, harbours were located in sheltered natural bays; later breakwaters were used to provide...
