For the real-time simulation of ship manoeuvring, it is required to estimate the hydrodynamic forces with high accuracy. Current methods to determine the hydrodynamic coefficients prove to be time consuming and labour intensive. In this thesis, a method based on Singular Value Decomposition is proposed to determine the hydrodynamic coefficients...

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...

Due to a low restoring force as well as lack of damping, the roll motion of a<br/>vessel is usually the motion with the highest amplitude of all degrees of<br/>freedom. Therefore, in history many have tried to stabilize rolling ship<br/>starting with Watts in 1883. He described the damping of the roll motion by<br/>having a group of men running...

A previous work at Royal IHC, following the observation from sea trials of trailing suction hopper dredgers (TSHD) that the turning performance of bow tunnel thrusters significantly reduced at slow forward speeds, studied the flow behaviour and performance of bow tunnel thrusters at slow forward speeds using Computational Fluid Dynamics (CFD)....

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...

In deep sea mining polymetallic nodules are harvested that are found in large parts of the oceans at depths of up to 6000 metres. A deep sea mining system collects such nodules using a seabed crawler and transports them to a continuously sailing ship by pumping them via a jumper through a free-hanging riser. The position of the seabed crawler...

Comparative study into the effects of applying different spectral wave models to workability prediction of the Ampelmann A-type. Single peaked (wind sea), double peaked (wind sea and swell), and hindcast wave spectra are compared.

To compensate the heaving motion of a payload during deep water offshore installations, hanging from an on-board crane on a monohull vessel, a new concept is being investigated. By actively rolling the vessel using ballasting systems, the coupled heave motion of the crane tip can be reduced significantly. This is investigated by building a...

The Ocean Cleanup’s goal is to extract, prevent and intercept plastic pollution by initiating the largest clean-up in history. It aims to achieve this by installing a large moored floating barrier, which passively concentrates the plastic debris using the ocean currents. In this thesis an alternative to this concept is developed and evaluated....

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...

Offshore wind turbines are growing significantly to become a cost-effective alternative for the offshore oil and gas market. This causes rapid growth of offshore wind turbine foundations (monopiles). Currently, monopiles are installed using jack-up vessels like Aeolus. However operations will be limited by crane capacity and its cost...

The aim of this work is to study the performance of the selected wake oscillator model in predicting the vortex-induced vibrations (VIV) response of a free-hanging vertical riser subjected to certain imposed harmonic oscillations at the top. This model is a simplification of the situations commonly found in offshore industries when a marine...

This thesis work is a starting point for the Flettner-rotor field of the wind-assisted ship propulsion research of TU Delft and POLIMI. During the development of this project, the flow around a bare spinning cylinder is investigated, introducing the Flettner-rotor without its end plate. The simulations were carried out in 2D and 3D with the...

Contrary to conventional conversion FPSOs, new-build FPSOs are not equipped with a propulsion system. This thesis explores the idea of installing a cost-effective low-power propulsion system on a new-build FPSO and letting it transit self-propelled to its destination, without compromising the safety. To this end, a computational tool is...
