Quy, N. M. (author), Łazuga, Kinga (author), Gucma, Lucjan (author), Vrijling, J.K. (author), van Gelder, P.H.A.J.M. (author)This paper presents an attempts towards creation of generalized models of ships manoeuvring area determination and ship performance created on the base of real simulation results. Those models are needed for better understanding of the safe navigation process in ports areas and its approaches and for risk analysis when no full information...journal article 2020

(author), Hulscher, S.J.M.H. (author), Lansen, A.J. (author)This paper explores an alternative method to determine extreme surge levels at the Dutch Coast. For this exploration, specific focus is on the extreme water level at Hoek van Holland, The Netherlands. The alternative method has been based on a joint probability model of the storm characteristics at the North Sea. The intent of this method is to...conference paper 2014

Wang, L. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author), Ranasinghe, R.W.M.R.J.B. (author), Maskey, S. (author)To guarantee a safe flood defence in a changing environment, the adaptation to climate change needs to be considered in the design of river dikes. However, the large uncertainty in the projections of future climate leads to varied estimations of future flood probability. How to cope with the uncertainties in future flood probability under...conference paper 2013

Dawotola, A.W. (author), Trafalis, T.B. (author), Mustaffa, Z. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author)This paper proposes a data-driven approach in determining an optimal inspection interval for a petroleum pipeline system. The approach accounts for the determination of both the probability of failure and its associated consequences. The probability of failure is estimated by fitting the historical data of failure of the pipeline into either a...journal article 2012

Pham Quang, T. (author), van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author), Thu, T.M. (author)Reliability and risk analyses are basic approaches, nowadays, for flood risk assessments in European countries such as the Netherlands, German, United Kingdom, etc. The methods also receive a lot of interest in developing countries. By considering uncertainties for both load and strength variables, the probability of failure for each element of...conference paper 2012

Dawotola, A.W. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author)A model is constructed for risk management of crude pipeline subject to rupture on the basis of a methodology that incorporates structured expert judgment and analytic hierarchy process (AHP). The risk model calculates frequency of failure and their probable consequences for different segments of crude pipeline, considering various failure...journal article 2011

Pham Quang, T. (author), Vrijling, J.K. (author), van Gelder, P.H.A.J.M. (author), Thu, T.M. (author)The application of reliability analysis in civil engineering is still an emerging technology, more so in geotechnical engineering and even more so in application to river dikes. However, much experience remains to be gained, recently, especially in European countries (the Netherlands, Germany, United Kingdom ) as well as in the United States of...conference paper 2010

Nguyen, D.V. (author), Van Gelder, P.H.A.J.M. (author), Verhagen, H.J. (author), Vrijling, J.K. (author)In order to avoid failure in its lifetime, a breakwater system has to be inspected and, if necessary, has to be repaired. In this paper, a comprehensive maintenance strategy with optimal inspection planning is formulated. Rational maintenance decision-making approaches are discussed. The proposed maintenance strategy combines time-dependent and...conference paper 2010

(author)This paper presents a comprehensive maintenance strategy with optimal inspection planning and its application to rubble mound breakwaters. In order to fulfil designated functions, a breakwater has to be inspected during its lifetime and has to be repaired if necessary. Actions of inspecting and repairing form a maintenance strategy.

Mai, C.V. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author), Mai, T.C. (author)This paper aims at risk analysis and the investigation of safety aspects of coastal flood defences in Vietnam. The sea dike system has been actually designed by a 20 to 25 years return period. From the current situation it seems that the dike system is not sufficient to withstand the actual sea boundary conditions. Accurate safety assessment of...conference paper 2008

Viet, N.D. (author), Verhagen, H.J. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author)In 2006 a Vietnamese Engineering Consultancy Company carried out a design study of a Naval Base at the location of the South of Doson Peninsula in Vietnam. A deterministic approach applied to the conceptual design of the breakwater system of the Naval Base resulted in a cross-section with a big armour layer and a rather low crest level. This...conference paper 2008

Viet, N.D. (author), Verhagen, H.J. (author), Van Gelder, P.H.A.J.M. (author), Vrijling, J.K. (author)An appropriate assignment of probabilities of failure to subsystems and components in a structural system can bring a minimum of costs and risk. In this paper, a method for economic optimisation of rubble mound breakwaters using pre-assigned probabilities of failure is presented. Application to a design case shows that the proposed method is...conference paper 2008
