SHIPP methodology: Predictive accident modeling approach. Part II. Validation with case study

Methods and models in process safety and risk management: Past, present and future

“…Most importantly, the predictive model was capable of predicting the risk profile of the system dynamically. The methodology description and case study validation are available in Rathnayaka et al (2011a;2011b). Application of SHIPP methodology to an LNG case study was later discussed (Rathnayaka et al, 2012).…”

Contribution of dynamic experience feedback to the quantitative estimation of risks for preventing accidents: A proposed methodology for machinery safety

“…In other cases, by using systemic calculations of the probabilities of causes responsible for the consequences, updating risk alerts the decision makers to hazardous scenarios that develop as the system evolves. In some cases, the calculations use system-related data that are entered real time (Swaminathan and Smidts, 1999;Rathnayaka et al, 2011). In others, data entry is done manually (Mili et al, 2009) and is therefore dependant on the good will of the organizations concerned.…”

Safety study of an LNG regasification plant using an FMECA and HAZOP integrated methodology

“…The DyPASI methodology was utilised to mitigate the deficiencies of the current HAZID techniques in the identification of unexpected potential hazards related to atypical scenarios and the integration of the recommendations from past atypical accidents. Rathnayaka et al (2011aRathnayaka et al ( , 2011b developed the new safety assessment methodology system hazard identification, prediction and prevention (SHIPP) to provide a guide for possible improvements at every step of the accident sequence process. Hazards related to LNG properties and processing were identified and analysed to investigate possible accident scenarios, causes and their consequences.…”

“…Therefore, the quantification includes uncertainties. However, the authors introduced a Bayesian updating mechanism to minimise the uncertainty in the quantitative analysis (Rathnayaka et al, 2011a(Rathnayaka et al, , 2011b.…”
