Design for decommissioning

PetroWiki

Draft Index for review by the Joint Industry project.  The final page will be completed soon with many additions

1 Statement of objectives

The D4D Database provides feedback from late life and abandonment operations.  It provides practical guidance to engineers when designing new facilities or modifying existing facilities

The challenges and issues encountered at the end of a facility's life may not be foreseen or correctly considered during the design phase. This lack of attention can make the eventual decommissioning work more technically challenging and costly.  The purpose of the database is to identify decommissioning issues based on real industry lessons learnt and translate these into potential solutions which could be implemented in future designs

2 History of JIP

Work group: formed in Aug 2016 with thirteen organisations

Initial project scope: boundaries identified – i.e. subsea only

Demonstrated economic value: examined the influence of decommissioning costs in the whole asset lifecycle

Structure for database: defined for use by Lead Design Engineers

Database populated: input from decommissioning community

Industry guidelines: started preparation to integrate findings and recommendations into the conceptual and FEED phases of the lifecycle

3 Decommissioning cost matrix

4 When to incorporate decommissioning in design

5 Database of lessons learnt and design guidance

6 Economic Benefits
