Effective and robust safety and environmental management system
Ensure that exploration and production is done safely and in a sustainable manner
Assure all stakeholders that activities that pose a threat to life, environment and assets are properly controlled
How to prevent major accidents – “black swans”
How arrange a proper response capability for major environemntal spills
How to establish predictability for the industry
How to prevent unnecessary business interruption and disturbance
How to manage all relevant legislation

Current Regulation in Brazil Regulatory bodies for Safety and Environmental aspects:
- The National Agency of Petroleum, Natural Gas and Biofuels (ANP): 17 Management Practices
- Marine Authority ( the Coast and Ports Directorate, DPC): Maritime Authority Standards, NORMAM
- Ministry of Labour and Employment: regulations, codes of practice and guidelines
- Environmental licencing: CONAMA and IBAMA
It seems to be a continued need for better understanding of objectives and expectations and further the implementation of the regulations and criteria to be applied for developing and approval of safety and environmental studies.
Overall, it is a “learning process” that goes between the Regulators and the industry and it will take some time until all parties have the same understanding and the conditions are understood, implemented and well applied.
Some areas for improvement when comparing best practices

Historical major accidents and related improvements and learning's:
Alexander Kielland (1980) Structural redundancy
Piper Alpha (1988) “Offshore Safety Case”
Exxon Valdez (1989) Double hull
Scandinavian Star (1990) Corporate accountability for loss of life
Texas City (2005) Improved understanding of major accidentsOccupational safety ≠ Major accident safety
Deepwater Horizon (2010)Are we prepared for worst case accidents?
Herald of Free Enterprise (1987) Increased freeboard, initiation of ISM
Estonia (1994) Requirements in crowd and crisis management

Need of improved quality in decisions at critical point
Importance of managing barriers and critical functions to prevent accidents and achieve corporate goals for safe and productive installations
Importance of organizing information to support decision makers
Importance of a visual, intuitive framework and “common language” for communication, consensus, and action across discipline and organization boundaries
Importance of providing practical guidance and training in challenging, high stress situations

Design vs Operations Phase Risk approaches Design stage – only a few specialists need to know
- They decide on risk reduction based on cost-risk benefit approach
- Complex risk approaches are necessary for some kinds of decisions
- Broad based decisions can be concluded with Risk Matrix
- Difficult decisions may require QRA (Quantitative Risk Analysis)
Operation stage – everyone involved need to know- What makes things safe- What is their role in maintaining the controls- Management and regulators need to be assured that the controls they
specified / agreed to are working

Swiss Cheese Model – barrier methodology
Major Accident
Emergency responseE.g. escape, evacuation
MitigateE.g. drainage, fire protection
DetectE.g. fire & gas detection, control systems
Prevent E.g. design, maintenance, procedures, competence

Barrier philosophy linked to the safety management system

The Bow Tie risk model
• Implements the Swiss Cheese model• Clearly identifies barriers in accident pathways• Critical barriers can be identified• Barrier ownership is assigned• Barriers linked to management system – Operations,
Engineering, Maintenance etc.

Summing up – how to meet the environmental challenge
Legislation and regulation is in place in Brazil. However, areas for improvement both regarding interpretation and implementation
Question mark whether we have sufficient focus on the operational safety and specifically the unexpected events potentially leading to environmental catastrophes
Barrier methodology and specifically the bow tie may be a tool to enhance and improve the safety and environmental performance
