INTRODUCTION

DECOMMISSIONING MINDSET

We need to think differently about delivering cost effective and predictable decommissioning projects

The closer we work together the more effective we are.

Safety risks – non operational.Do the same performance

standards apply?

The tax payer is paying and there is no production revenue.

In Planning, multi-skilled teams, execution and how we approach

Gains in the critical path have a significant impact. Flexible and agile

planning crucial.

In process and technology. We need to do things differently to achieve the

same outcome.
