In this thesis a model is set up to assess the economic viability of early stage buoyancy design concepts. The main research question is to find out if a versatile design approach to the buoyancy lifting concept, i.e. being able to take on multiple projects, can result in an economical viable solution for decommissioning offshore platform...

The new rapidly growing wind energy market has been moving to offshore waters the last few years. New techniques and growing experiences make it possible to move to challenging offshore domains and towards harsher conditions and deeper waters. From the oil & gas industry a lot of expertise is already available on support structures. The...

Jacket support structures are a preferred solution for offshore wind turbines in deeper waters. Extensive knowledge exists in relation to its construction technique as well as its crucial components, but due to considerable cost pressure, continued optimization is essential for the future competitiveness of the concept in the offshore wind...

Offshore wind turbines are exposed to complex irregular and highly fluctuating environmental conditions. The analysis is, therefore commonly performed in the time domain, resulting in a time consuming and computationally demanding optimization process. In order to reduce the computational cost, an optimization approach using the principle of...

The offshore industry and especially the oil and gas production, has faced a remarkable growth in the last decades, causing an increase in the population of offshore structures. The overwhelming majority of these structures are bottom founded and mostly made out of steel. Over these decades much experience has been gained with the design and...

Denim is something we all love to wear, worn by young and old, throughout the world. Denim’s graceful aging allows us to build valuable relations with it. Like a friendship, it becomes more personal and intimate with the passing of time. This jacket embraces denim’s characteristics to tell an unique dialogue with its wearer. Based on the wearers...

In pursuit of saving mother nature, man has been extending his boundaries to find renewable sources of energy. Wind being one of them, has been exploited in the past years with offshore wind gaining high popularity in the recent years. Owing to the high capital costs of the offshore wind sector, research has been directed to focus on technology...

In order to gain insight in maximum wave conditions in which installation of a four-legged suction bucket based jacket foundation could safely take place, a 2D time domain MATLAB model has been created, containing the most important features of a heavy lifting jack-up crane vessel and its appropriate rigging elements. The model is used to...

Pioneering Spirit, Allseas newest vessel, is specialised in offshore platform installation and decommissioning. The goal of this research is to find a solution for the interface between the topside lifting system and platform jacket legs without the necessity of lengthy preparation work to platform. In a research regarding platforms...

Prefabricated vertical drains (PVD) are used to accelerate drainage and consolidation of soft sediment. An effective functioning of these PVD depends on its capacity to drain water from the subsurface. Among other causes, the clogging of filter jackets is thought to be of a considerable negative influence on the functioning of PVD. Current...

The first platforms for oil and gas production in the North Sea have been installed around 1970. Since then about 500 platforms have been built to explore the North Sea oil and gas fields. Now, after 30 years of use, the first platforms are abandoned, creating a demand for innovative and economical removal concepts. Heerema Marine Contractors ...

Random wave and current forces acting on an offshore structure, cause random base shear forces in time. The peak base shear is the maximum value of base shear that occurs during the passage of a wave. The extreme base shear is the maximum value of base shear that occurs within a period of time, say one hour. So far, the distributions of extreme...

Dit verslag geeft een stap voor stap beschrijving van het oplossen van een door de vakgroep kustwaterbouwkunde gesteld probleem. Binnen deze vakgroep was behoefte aan een computerprogramma dat in combinatie met een staafkrachtenprogramma geschikt is voor het maken van een statische analyse van ruimtelijke vakwerkconstructies in zee (jackets e.d....
