NEW REGULATORY REQUIREMENTS
MACONDO BLOWOUT ???
The Norwegian regulations are mainlyperformance-based
The U.S. regulations are primarily prescriptive
The intention with a performance-based regime is to make the operator regulate own activity when it comes to safety, health and environment (SHE)
The intention with prescriptive regulations is to prevent accidents by identifying specific technical requirements that the operator must comply with. The Authorities control the operator’s activity inter alia through approvals and inspections.
Mainly risk-based approach, systematically identify and mitigate risks.
Separate authorities for resource management and SHE management
Agency with coordinating role in the development and supervision of SHE regulations.
Establish barriers on technical, operational and organisational levels
Latest edition ofapplicable regulations and referred standards for mobile units
Two independent and tested well barriers in all drilling and well operations
Recertification of blow-out-preventer (BOP) every 5 years
AND one area where we are not so different
Validation of functionality and capacity of oil recovery equipment ?
A lot of understandable “wait and see”.
