expertise o f the designer. An inherent weakness in the development is the interface, not only between components of the design, but
also between designer and operator.

Traditionally, engineering design is based on sound engineering judgment with recognised standard specifications, engineering
codes, checklists and guides. In spite of many decades of successful practice, some 25 to 30 percent of accidents are still due to
Technical failure, and it is there that ADEPP can make significant contribution to improve quality.

Over the past 20 years, attempts have been made to decrease the likelihood of technical failures and accidents by using an inherently
safer design. However 70 to 75 percent of accidents, human failure (inattentiveness, poor judgment, and negligence) is the decisive
factor A diagnosis of the chain of events, leading to operational accidents shows that many of these could have been prevented by
judicious design, by adequate procedures and precautions, or by specific training. Specific training for design team and operational
jobs is a
must. When hazardous situation develops, the competence of the operator is of decisive importance.

It is for this reason that in 1993, Fabienne Salimi and Frederic Salimi decided to initiate the development of an innovative tool called
ADEPP (Analysis & Dynamic Evaluation of Project Processes).  ADEPP applies a dynamic simulation in process safety, thereby
taking into account the evolution of fire & explosion, with respect to response time of safety systems.  ADEPP offers the capability to
trace and audit the results of risk assessment. The final step is t he training of the design engineers and operators regarding the
consequences of accidents in chemical, petrochemical, and petroleum industries for both offshore and onshore installation.

ADEPP is designed to create a graphical system of review for both designers and operators. It will be used as a means of auditing
equipment and processing safety as well as a management tool for the industrial customers of ADEPP Academy.

ADEPP can also federate the different software packages used by project for different tasks such as dynamic simulation,
consequence modelling, risk studies.

Dynamic simulation can assist and guide the design as well as the operator team making more precise decisions and corrective
actions for a specific scenario of the particular risk.

A definition or example of a risk scenario would be preparation of event logic, fault trees and performance standards. All are modelled
and simulated in ADEPP and the results are presented in pleasant and convivial interactive graphical interfaces.
