Independence here is structural. It is not a statement of intent.
Portis is retained by the party that will own and operate the asset. It supplies nothing, resells nothing, and holds no agency or margin arrangement with any manufacturer whose equipment it may specify.
- 01
No supply interest
assessments carry no commercial position of their own
By structure
- 02
One reader
the design, the offer and the claims that follow are read by one party
By engagement
- 03
Written divergence
where the operating case and the contract minimum diverge, it is recorded
By method

Specified before it is built.
Where we add most
| Moment | What fails | What Portis does | When | |
|---|---|---|---|---|
| 01 | Feasibility | throughput assumed rather than tested | operating case written and tested before capital is committed | Before commitment |
| 02 | Specification | equipment chosen without the yard it must serve | requirements stated so they can be tested at handover | Before tender |
| 03 | Procurement | awarded on capital price alone | spares, energy, availability and maintenance levelled before award | Before award |
| 04 | Handover | commissioning planned after the fact | held to the criteria written at tender | Before acceptance |
Earliest intervention · lowest cost of change
The engagement ends with a position the owner can defend to a board, a lender or an authority.
