Hammer, T.C. (author), Puolakka, Otto (author), Hendrikse, H. (author)A modeling approach to simulate ice-induced vibrations of vertically sided offshore structures in ice tank experiments is presented. The technique combines replica modeling with the preservation of kinematics during ice-structure interaction. The technique was chosen based on the theoretical understanding that ice-induced vibrations are...journal article 2024

Sharma, Astha (author)In the past decade, suction caissons have emerged as a preferred offshore foundation solution for wind turbines due to their silent installation process and potential for recyclability. However, there has been growing speculation regarding the necessity of under base filling, which involves filling the gap between the top plate of the suction...master thesis 2023

Scharnke, Jule (author), van Essen, S.M. (author), Seyffert, Harleigh C. (author)In the assessment of wave-in-deck loads for new and existing maritime structures typically model tests are carried out. To determine the most critical conditions and measure sufficient impact loads, a range of sea states and various seeds (realisations) for each sea state are tested. Based on these measurements, probability distributions can...journal article 2023

van Essen, S.M. (author), Seyffert, Harleigh C. (author)Green water and slamming wave impacts can lead to severe damage or operability issues for marine structures. It is therefore essential to consider their probability and loads in design. This is difficult, as impacts are both hydrodynamically complex and relatively rare. The complexity requires high-fidelity modeling (experiments or CFD),...journal article 2023

(author), Hammer, T.C. (author), Ziemer, Gesa (author)In the FATICE project we have addressed the fatigue damage on fixed offshore structures exposed to drifting ice. This is an important challenge in the development of energy production from offshore wind in the Baltic and involves at least five element: a) define ice statistics, b) predict the structural response (ice-structure interaction...conference paper 2021

Cabboi, A. (author), Kamphuis, Thijs (author), van Veldhuizen, E. (author), Segeren, M.L.A. (author), Hendrikse, H. (author)An alternative option to the traditional grouted joint for wind turbines is a direct steel-to-steel connection, also known as slip joint. In a recently published work, a proof of concept of a vibration-assisted installation and decommissioning technique of a slip joint was illustrated. Leveraging on the obtained results, the current study shows...journal article 2021

Verma, Amrit Shankar (author), Jiang, Zhiyu (author), Ren, Zhengru (author), Hu, Weifei (author), Teuwen, Julie J.E. (author)The presence of rain-induced leading edge erosion of wind turbine blades (WTBs) necessitates the development of erosion models. One of the essential parameters for erosion modeling is the relative impact velocity between rain droplets and the rotating blade. Based on this parameter, the erosion damage rate of a WTB is calculated to estimate...journal article 2021

Rodenburg, Jorrit (author)Offshore wind turbines are designed to persist harsh environmental conditions, including corrosion. Pitting corrosion is one of the most dangerous forms of corrosion. In combination with a fatigue loading, a corrosion pit could result into the failure of a structure, due to a minimal weight reduction. Of the corrosion fatigue process, the...master thesis 2020

Seo, Ho Seung (author)Fatigue failure is a governing limit state for marine structures. Marine structures are composed of the numerous structural members connected by the welded joints which are the typically governing fatigue sensitive locations. In this thesis, attention has been paid to...master thesis 2019

Bridges, Robert (author), Riska, K.A. (author), Hopkins, Mark (author), Wei, Ying (author)Ice encroachment is the accumulation of ice atop a platform and results when ice drifts against a platform. Most often this occurs in shallow water but in principle can occur in deep water if the ice drift length is long enough. As the ice drifts against the platform it is broken and generates rubble and ice piles in front of the platform, and...journal article 2019

Besseling, Floris (author), Lengkeek, H.J. (author), de Waard, Huig (author), Nieuwenhuis, Kees (author)The Afsluitdijk is one of the Dutch Delta programme landmarks. Afsluitdijk is a 32 km long primary flood defense, separating lake IJsselmeer from the Wadden Sea and protecting large areas of the Netherlands against flooding. Over the period spanning 2018 - 2022 the levee will be upgraded by the consortium Levvel (BAM, Van Oord and Rebel). Ice...conference paper 2019

van der Horst, M.P. (author)Ship and offshore structures are prone to fatigue damage as they are cyclically<br/>loaded by waves. Therefore, regular inspection is needed in order to confirm adequate structural integrity throughout the entire service life of the structure. Detected fatigue cracks that are too long for safe operation need to be repaired. Detected cracks of...doctoral thesis 2018

Rivera Arreba, I. (author), Bruinsma, N. (author), Bachynski, E. E. (author), Viré, A.C. (author), Paulsen, B. T. (author), Jacobsen, N. G. (author)Floating offshore wind platforms may be subjected to severe sea states, which include both steep and long waves. The hydrodynamic models used in the offshore industry are typically based on potential-flow theory, and/or Morison's equation. These methods are computationally efficient, and can be applied in global dynamic analysis considering...conference paper 2018

Hendrikse, H. (author)Offshore developments in ice-covered waters, such as the Arctic Ocean or Baltic Sea, have received increasing attention from the petroleum and wind power industries over the past decade. Sustainable developments in such waters can contribute to a balanced energy future provided that the deployed offshore structures are designed to be safe. The...doctoral thesis 2017

Vittori, F.E. (author)Floating structures as spar, semi-submersibles and TLP have been proposed for offshore wind turbines for deep waters (>60m) according to the report of Arapogianni, Moccia, Williams, & Phillips (2011), where bottom fixed sub-structures are technically and economically not feasible. Several floating concepts have been designed and just some of...master thesis 2015

Andrianov, A.O.I. (author)Due to the growth of their population, urban development and the corresponding expansion of land use, several countries have decided to build artificial islands in the sea to decrease the pressure on the heavily used land space. The reclamation of the land from the sea is already widely applied, however, there is also an attractive new...doctoral thesis 2005

Böcker, B.M. (author)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 ...master thesis 2001
