Scope

The overall goal of the Offshore Structural Reliability Conference is to contribute to:

• Understanding and documenting the collective knowledge of offshore structures reliability
• Maximizing the learnings from operational experience
• Providing knowledge management (convey existing knowledge; especially new knowledge…balance experience and devoted beginners)

Stakeholders

• Operators
• Industry Organizations
• Regulators
• Academics
