Zeguang, W. (author)The phenomenon that waves break in sea has long been existing, but the nature of wave breaking and the effects it would bring have not been weIl understood. However, as nowadays more and more offshore installations go to deep sea and/or are operated under more violent wave climates, the effects, which are caused by breaking wave impingement up...master thesis 1987

De Blaeij, T. (author)Monopiles are being used more extensively for offshore wind turbine foundation. Current guidelines on the construction of fixed offshore foundations still base the design of laterally loaded piles in sand on empirical data (p-y curves), originating from the oil and gas industry, from field tests executed in 1974 on 0.61 m diameter piles. However...master thesis 2013

Romp, R.H. (author)Nowadays suction caissons are extensively used for anchoring large offshore floating facilities. Installation of suction caissons in coarse grained soils is achieved by induced seepage flow in the soil. This reduces the soil resistance at the caisson tip, which contributes to the installation process. Installation in fine grained materials with...master thesis 2013

Beemsterboer, T.N. (author)Subsea rock installation is often used in offshore engineering. With offshore activities in increasing water depths a flexible fallpipe is currently used to accurately install the rock particles. The total required volume of rock material during installation can be determined by summing the geometrical volume, the operational losses and the...master thesis 2013

Chatzivasileiou, G.I. (author)Suction caissons are used more and more for various in the oil&gas and offshore wind industries. Although, the use of suction caissons is not new, uncertainty still exists regarding their installation, due to the varying soil profiles encountered and the absence of experience within the offshore industry. Prediction methods, regarding the...master thesis 2014

Bakker, F.C. (author)This Msc graduation study covers the installation of topsides on a jacket by an offshore heavy lift crane vessel, and its related problems. One of the problems take place after the topside is hoisted on the jacket, during the weight shift from the hoist cable onto the jacket. The topside then exerts large horizontal forces upon the crane and...master thesis 2015

Leontaris, G. (author)During the past years a lot of attention has been drawn towards the development of renewables, due to the expected depletion of fossil fuels and political decisions. Offshore wind energy is considered as one of the most promising renewable energy sources, however the cost of offshore wind farms have not yet reached competitive levels. Hence...master thesis 2015

Hoes, R.S. (author)This thesis researches the change of the hydrodynamics of jack-up spudcans close to the seabed and the influence of this change on calculated jack-up motions. Two GustoMSC jack-up designs are selected as typical: a large drilling jack-up (CJ-70), and a small wind turbine installation vessel (NG-2500X). Limits for allowable wave heights during...master thesis 2015

Rodenburg, M.L. (author)Crane companies face difficulties when installing blades of wind turbines: the tall cranes required for installation have large sail areas and are unable to lift 80% of the time due to too high wind speeds. Also load control by men from the ground is limited in high winds. To design a new installation method, enabling more lifting days per year...master thesis 2015

Panagoulias, S. (author)Suction caissons are used in a variety of bottom founded and floating offshore applications, in shallow and deep waters. The present research focuses on the analysis of suction-assisted installation in sand. Suction pressure measurements from a number of field projects and laboratory centrifuge tests in sandy soils led to find that, in 70% of...master thesis 2015

De Groot, K. (author)Trends in the offshore wind market show that newly installed wind farms move towards deeper waters. Wind turbine generators are currently installed using jack-up vessels, which have a limited operating depth. Installation of wind turbines using a floating vessel is an alternative for the current method, but blade installation is an area which is...master thesis 2015
