How good is good enough in DP calculations?: A case study into uncertainties involved in the DP capability prediction process

Currently there are three methods of calculating the Dynamic Positioning capability of a vessel namely: static calculations, real-time time domain simulations and fast-time time domain simulations, although the outcome of the last two should be identical. In each of these methods a set of input variables is required to perform the calculations....

Long-Term Infrastructure Planning of Airport System in Developing Country

Developing scenarios for the European plastics industry based on the uncertainties of shale gas

Towards an efficient sensitivity analysis of wave forcing in coastal erosion studies: A case study of Negril Coast, Jamaica

This research investigates approaches to conduct an efficient sensitivity analysis of wave forcing in coastal erosion studies. For this three speed-accuracy trade-offs have been assessed: (i) between the use of a simple and a complex model, (ii) between the use of several methods for conducting a sensitivity analysis, and (iii) between the use...

Uncertainties in future dike design

A dike is designed for an extreme event which greatly exceed the situation under daily circumstances. The expected loading during such an event is, however, difficult to estimate. Inherent uncertainties in nature and epistemic uncertainties in models and statistical data impede a clear verdict about the exact loading on a dike. Consequently,...

Design of a probabilistic decision support tool for the cable installation of an offshore wind farm

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...

Dealing with Uncertainties in Rural Restructuring Projects: A comparison between theory and practice

Managing uncertainties in practice differs from the suggested uncertainty management approach in the (scientific) literature. Uncertainty managers are not aware of the many tools and techniques that are available to manage uncertainties in their projects. They deal with uncertainties in a rather implicit way with varying success. Furthermore it...
