Consultancy core
The work that shapes the programme.
Endura concentrates on the front end, decision basis and execution
strategy. The structure remains technically useful to operators,
contractors, assurance teams and management reviewers.
01 · Primary service
Decommissioning studies and business case development
From early screening through defined study phases, Endura frames
the asset boundary, compares credible pathways, develops the
technical basis and produces a review-ready package for
management, regulators or procurement.
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.
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.
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.
