Improved reaction loads incroporated in sea fastening designs of offshore wind turbine components: A study on preparing the reaction loads calculation method for the future

The offshore wind energy market is expanding and the number of offshore wind turbines being installed in the near future is rising. Offshore wind turbines are being installed further offshore and in deeper waters. Besides, to lower the cost of wind energy offshore wind turbines are increasing in size and power output. Both wind turbines and...

Combining cross-shore and longshore processes in long-term probabilistic coastline modelling: Development of a probabilistic framework

Many coasts around the world experience coastal erosion as a result of climate change, lack of sediment supply or human interventions. In the coming decades, coasts will be exposed to increased natural forcing because of climate change and sea level rise, leading to increased risks of coastal flooding and erosion. As sandy coasts are highly...

Toward more reliable cost estimations for asset replacement projects: Incorporating probabilistic models and the price uncertainty in the preliminary cost assessments for asset replacement projects

The majority of existing infrastructure assets are ageing, and sooner or later, they will have reached the end of their service life. As a result, many asset owners are confronted with large-scale replacement projects in the coming decades. Annually, they allocate a significant number of resources, but these budgets are never adequate for...

Connecting deterministic and numerical methods to better estimate the probability of flooding for clay dikes

Dikes protect people and lands all around the globe. With rising sea levels, the importance of well-designed dikes has never been more essential. One of the main factors that can compromise the stability of dikes are macro-instabilities. Macro-instabilities can cause dikes to lose their water bearing potential, leading to floods. Methods are...

A probabilistic approach for optimizing the resurvey frequencies of the Netherlands Continental Shelf

Bathymetric surveying of the Netherlands Continental Shelf (NCS) is taken care of, by the Dutch Hydrographic Office and Rijkswaterstaat. The survey frequencies vary from location to location depending on a set of factors defined by the authorities. These are the minimum depth, draught (the difference between seafloor depth and ship’s keel),...

Safe Flight Envelope Uncertainty Quantification using Probabilistic Reachability Analysis

Loss of Control is the primary contributor to aviation fatalities. To prevent this type of accident, flight envelope protection is considered to be a necessary development. The calculation of the Safe Flight Envelope provides a bound on the states that can safely be approached by the aircraft. Although theoretically accurate, some states may not...

Probabilistic analysis of manufacturing variability and wear of core engine components

In the framework of LuFo R\&amp;T projects a number of Rolls-Royce Deutschland Low and High Pressure Compressor rotor blades were geometrically scanned at the beginning and end of their life cycle. Based on this data component wear, ageing and manufacturing variability across the life cycle of the engine can be derived. Using Computational Fluid...

Predicting Coastal Hazards with a Bayesian Network

Recent and historic events have demonstrated the European vulnerability to coastal floods. Larger and more extreme events in Asia and the Americas have shown the devastating effects that these low-frequency high-impact floods can have. This thesis contributes to the development of an Early Warning System (EWS) for marine coastal hazards. The...

Impact Assessment of Extreme Storm Events Using a Bayesian Network

The most densely populated and economical most valuable areas in The Netherlands lie below mean sea level. These areas are protected against the sea by a coastal dune system. The vital importance of this dune system is reflected in the extensive collection of Dutch legal regulations that ensure the safety level of the dunes. Current safety...

Differences between a 3 dimensional probabilistic method of berthing structure design and the traditional method of a berthing structure design

Jetties are designed by the guidance of the deterministic standards. These standards are based on the standardized values of safety factors (semi-probabilistic) and use the load and the capacity of every element as a standard value. The interaction of every separate element as a part of a whole is not taken in to account. The use of...
