Decommissioning & Operations Optimization

Brownfield performance optimization and end-of-life execution: cost-optimized plug and abandonment, subsea and structural removal, and the method statements, FEED and bespoke tooling behind them.

When we get the call

Typical scenario

A campaign is being scoped and the wells and subsea removal scopes are being engineered by two teams that never meet

Typical scenario

The complete field decommissioning plan and cost need updating, to properly map the ABEX, the abandonment expenditure

Typical scenario

An offshore campaign keeps running into downtime, and is accumulating failures and incidents

Typical scenario

An offshore decommissioning strategy is hesitating between custom made special equipment and off the shelf equipment only

Typical scenario

A large decommissioning campaign raises a question: one large campaign, or four small specific vessels

Typical scenario

Several wells to plug and abandon, without a complete well integrity analysis of each one

What we deliver

  • Full decommissioning plans covering wells, SPS and SURF infrastructure
  • Cost-optimized plug and abandonment engineering and well integrity management
  • Brownfield workflow optimization, operating management systems and independent compliance audits
  • Bespoke removal tooling: XMT interfaces, custom ROV tools and structural removal equipment, from concept through manufacturing oversight and FAT
  • Streamlined method statements and decommissioning FEED your offshore campaign can be built on

How we work

Decommissioning money is rarely lost in the office. It is lost offshore, in vessel days nobody planned for and interfaces nobody owned. Quartic engineers the well and subsea scopes together, cost-optimized plug and abandonment alongside structural and subsea removal, so the method statement that reaches the rig floor is the one the engineering actually supports. Where a campaign needs equipment no catalogue sells, we design it, oversee its manufacture and witness it at FAT before it goes in the water.

Every engagement follows the four Quartic principles, agile, transparent, innovative, hands-on, with deliveries tailored to each client's approach and standards. Our partners stay personally involved from kick-off to close-out.

The people behind it

Partners whose disciplines match this work. The person you scope with is the person who shows up.

Common questions

Do you cover the wells side as well as subsea removal?

Yes, and that is the point of this service. Cost-optimized plug and abandonment and well integrity sit with our drilling and well engineers, subsea and structural removal with our subsea team, and both work to one method statement.

Can you build the tooling you design?

No, we are not a manufacturer. We engineer the tooling, including XMT interfaces, custom ROV tools and structural removal equipment, then supervise manufacturing and witness factory acceptance testing on your behalf.
