This report presents a method to calculate the frequency characteristics of a vessel that takes into account the dynamic interaction between the vessel and the Ampelmann system. Insight is provided into the dynamic interaction between the vessel and the Ampelmann system and the factors are identified that determine the changing dynamic behaviour...

Nowadays, as it is a easy sequence in construction and installation, the monopile is the most common used support structure. Due to the limitation of water depth and lifting capacity, jack-up vessels gradually become unable to fulfill the demands of monopile installation. Floating vessels can expand the market of wind farminstallation due to the...

The starting point of this research is to asses possible shortcomings of the combined operation of a Dynamic Positioning (DP) vessel and a motion compensation system, with respect to the amount of energy that is used. The motion compensation system is used to allow a safe transfer from the vessel to a static offshore structure. Both systems have...

When working offshore on a floating vessel, the vessel will be subjected to wave induced motions and with a moving crane tip, a suspended load can start to swing. When the motions of the load become too large, the operation is interrupted. Alternatives such as jack-ups, function as a fixed platform to which the crane is attached, therefore...

Motion compensation for personnel transfer has greatly reduced costs and increased accessibility for offshore assets operation and maintenance. Solutions exist using hexapods or gangways that make a stiff connection by clamping to a customized offshore structure. State of the art gangways allow for a stepless workflow and have a rubber tip which...

Offshore wind farms are a sustainable source of energy, but these farms require maintenance which is very expensive using the current techniques. Huisman Equipment B.V. proposed a new type of offshore motion compensated crane that is capable of reaching the height of the nacelle of these wind turbines. The crane has a compensation system on the...

In the offshore industry, there is a growing demand for designing efficient, sustainable and competitive products. In order to fulfil the component requirements, a method named topology optimization can be applied. This is a mathematical design method which can be used in the early phases of the design process.At IHC there is an interest of...

After years of using fossil fuel, the transition to renewable energy sources need to be made to limit the increase in temperature and to support the future energy demand. To support and speed up the transition phase from fossil fuels to renewables it is necessary to decrease the costs. Offshore Wind Turbines are widely used for the production of...

Objects floating on or near the water surface (e.g. vessels, and floating wind-turbines) suffer from motions induced by waves of varying height, direction, and frequency. This not only causes unpleasantness for passengers and crew of ships but also it limits the accessibility to the offshore platforms. Bosch Rexroth with their partner Barge...

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...

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...

ISAR imaging is a well known technique which uses range and Doppler information from a radar to generate an image of a moving target. Research performed on the combination of a large receive array with airborne ISAR is scarce. This thesis is aimed to reach the highest possible image quality for AMBER, a radar with a 24 element receive array...

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...

A Fall-Pipe system deposits rock on the seabed for the protection of submerged objects. Due to the irregular motion of a vessel on the waves the accuracy and efficiency of the rock dumping process is limited. This thesis develops a motion compensation system for a modular Fall-Pipe system developed by Vuyk Engneering. From literature it appears...

Due to an increase demand for renewable and sustainable forms of energy, the offshore wind industry is growing rapidly. To make wind energy more cost-effective, new wind turbines are becoming larger in size and are placed further offshore. This results in deeper waters, making the installation more difficult. The current methodology uses a jack...

Using a floating vessel operating on its DP-system and using a motion-compensated pile gripper to install monopiles could be the installation method of the future. Therefore, this thesis focuses on this method. The main objective of this thesis project is to build a model that accurately describes the motions of the Stella Synergy, the monopile,...
