Disposal of
end-of-life vessels in an environmentally sound and safe manner is a major
challenge today. In the present study an attempt has been made to develop a
three-step risk assessment method – which offers a systematic pedagogic
approach for the “analysis team” comprising of production managers, safety
officers, safety supervisors and the designated expert monitor to reduce risks
and enhance safety at ship recycling yards. The three-step risk assessment was
performed in 35 ship recycling yards through questionnaire surveys and
door-to-door communication. Thus, 35 data sets from field personnel at the ship
recycling yards, each data set with 8 risk indexes (4 risk indexes each, before
and after implementing corrective actions) were collected. In addition, 9 data
sets were collected to document the perceptions of experts. In all, a total of
44 data sets were collected and used to validate the risk assessment method.
Validation of the three-step method, essentially addresses the differences (or
similarities) in “perception of risk” by several health, safety and environment
(HSE) managers who volunteered for the risk assessment exercise. In order to
validate the risk assessment method, three validation protocols were developed.
Consistency check on the data sets was also performed and it was found that the
relationship was linear with the slope close to unity. The example illustrating
the application of Three Step Method in identifying and minimizing risks
provides clear understanding for the users of this method. Evidently, the
three-step risk assessment method developed in this research appeared to give
consistent results in a variety of scenarios of validation.
