“…Further, each risk type is divided into elementary risk factors. The risk factors are ranked on a scale from 0 to 3, where a higher value represents a greater risk potential of that activity (Meinhold 1998). These risk factors are used for pairwise comparison using the methodology provided in Sadiq et al (2003a).…”

Environmental risk management is an integral part of risk analyses. The selection of different mitigating or preventive alternatives often involve competing and conflicting criteria, which requires sophisticated multi-criteria decision-making (MCDM) methods. Analytic hierarchy process (AHP) is one of the most commonly used MCDM methods, which integrates subjective and personal preferences in performing analyses. AHP works on a premise that decision-making of complex problems can be handled by structuring the complex problem into a simple and comprehensible hierarchical structure. However, AHP involves human subjectivity, which introduces vagueness type uncertainty and necessitates the use of decision-making under uncertainty. In this paper, vagueness type uncertainty is considered using fuzzy-based techniques. The traditional AHP is modified to fuzzy AHP using fuzzy arithmetic operations. The concept of risk attitude and associated confidence of a decision maker on the estimates of pairwise comparisons are also discussed. The methodology of the proposed technique is built on a hypothetical example and its efficacy is demonstrated through an application dealing with the selection of drilling fluid/ mud for offshore oil and gas operations.

“…These stressors have also been incorporated in the development of the present model. In addition, Meinhold [9] discusses the physical effects of the material deposited. This includes burial effects and changes of grain size caused by deposition of particles with diameters differing from the natural grain size at the drilling site.…”

Modeling environmental impact on sediment caused by discharges deposited on the sea floor

A model has been developed that is able to model various types of impact on the sea floor caused by the deposition of particle matter and chemicals (attached to the particle matter). Particle matter may also contain heavy metals. The sediment is assumed to be represented by natural grains and porewater. The concentrations of dissolved chemicals in the pore water are assumed to be bioavailable, and the concentrations (toxicity) in the pore water are then given by partition of the chemicals (and heavy metals) between the pore water and the sediment. Other stressors caused by the discharges deposited are oxygen depletion (caused by the biodegradation of the chemicals deposited), generation of "exotic" sediment (caused by the particle size distribution of the particle matter deposited, which may have another distribution than the original sediment) and burial. All these factors are embedded into a numerical model that is able to simulate these stressors as a function of sediment location and time.
