02

ARO basis support

Engineering support behind the provision basis, with scope logic, key cost drivers and documentation caveats stated clearly.

03

Method and engineering development

Removal, isolation, demolition, logistics and well P&A methodology support shaped around the asset and decision stage.

04

Contracting and execution strategy

Scope packaging, interfaces, contract models and tendering logic that place risk where it can be managed.

05

Regulatory and permitting pathway

Pathway mapping and evidence planning for the applicable jurisdiction, aligned to the actual scope.

From liability to closure

A disciplined route from uncertainty to action.

The work begins with the decision the client needs to make. Each stage improves the basis, exposes remaining uncertainty and defines the next practical action.

About Endura

Independent advice, informed by execution.

Endura combines senior offshore judgement with disciplined front-end engineering. The consultancy stays focused on the decisions that establish scope, cost basis, commercial strategy and the path to execution.

The consultancy

Specialist support for late life and decommissioning decisions.

Endura Decommissioning is the consultancy offering of Van Iersel Projects Pty Ltd. It supports operators and delivery teams where inherited scope, uncertain data or unresolved interfaces are preventing a clear decision.

The role is independent and vendor-neutral. decomm.ai is introduced as a separate platform offering only where documentation intelligence would materially improve the basis.

Director · Endura Decommissioning

Jed van Iersel

Jed has more than 20 years of offshore decommissioning, heavy-lift and demolition experience. Endura was established to bring execution-grounded judgement into the planning stage, where scope, cost and risk decisions are still changeable.

The leadership role remains practical: shaping the technical approach, challenging the inherited basis and keeping the advice independent of a preferred equipment or contractor solution.

Where decomm.ai fits

Asset intelligence for decisions constrained by inherited data.

decomm.ai structures source records, scores documentation integrity and helps teams identify which gaps are most likely to affect scope confidence and targeted cost drivers.

The platform is commercially separated from the consultancy offer. It can support an Endura engagement or be considered independently.

Boundary kept explicitdecomm.ai informs the engineering and estimate basis. It does not set the accounting provision or replace engineering review.

Who the work supports

Built for teams carrying liability, assurance or delivery obligations.

The same asset can look different to a board, an engineering team, a contractor and a regulator. Endura structures the work so each group can see the basis, the limits and the decision path.

Operators and asset owners

Define the liability, improve the decision basis and set a practical route through study, approval and execution.

EPC and specialist contractors

Clarify scope, interfaces and delivery logic before commercial commitments harden.

Boards, finance and assurance

Understand what the engineering basis supports, where judgement remains and what action is proportionate.

Regulatory and technical reviewers

Review a structured evidence trail, assumptions register and defined pathway to closure.
