5.1. A successful case study
After the REPSOL accident occurred in 2003, new corporate safety strategies were implemented in the company in order to improve safety at all levels. These strategies where fully applied to the projects C-10 (Cartagena refinery expansion) and ADI-1000 (Bilbao Petronor refinery extension), affecting 22,200 people and 700 contractor, resulting in 37 million hours worked with a Loss Time Frequency Injury (number of lost-time accidents per million hours worked) of 1.05 (much lower than Spain average index of 50 for construction activities). Strategies used were: incorporation of international best standards, introduction of safety experts from outside companies, intensive use of Permits to Work (PTW) and SafeWorks Assignments (SWA), preventive observations, intensive training (around 235,000 h), widespread use of the HAZOP echnique as a tool for Process Hazard Analysis (PHA), etc. The C-10 project was selected among all the global Fluor orporation projects of the Energy & Chemicals - Downstream as winner of the “2011 E&C TOP (Totally Outstanding Project) HSE Project Award”, granted to the best project of the year, not only for the good accident rate results but also for the implementation of best practices, for the active participation of senior management in safety activities, and for the emphasis on and promotion of “Zero incidents”.
