We would rather be essential to three industries than familiar with thirty.
Generic software makes the operation adapt to it. Retrotech works the other way: eighteen years building for three industries, close enough to the work to know how a tank farm reconciles stock, how a fleet keeps class satisfied, and how a project keeps ten thousand drawings under control. Breadth is easy to claim. Depth has to be built.
Our industries
Where we go deep.
Oil & Gas — Refineries & Terminals
From the gauge to the ledger.
We build for the people who run refineries, tank farms, and storage terminals: tank inventory and readiness, product movements and custody transfer, commercial contracts and invoicing, and HSE compliance — with volumes corrected on real petroleum-measurement standards, so the figure on the bill of lading is the figure in the books.
- Tank inventory, movements, and custody transfer
- Contracts, pricing, and invoicing with enforced rules
- Volume correction per API MPMS Ch. 11.1 and ASTM D1250
Maritime — Ship Managers & Owners
The whole fleet, ship and shore.
For ship managers and owners running vessels at sea: planned maintenance on a system type approved by DNV, defects and condition monitoring, procurement and spares, crewing, HSSEQ and vetting readiness, and the emissions regimes — on board each vessel and in the office, in step even without a live connection. Live today on more than a hundred vessels across the UAE, Greece, and India.
- Planned maintenance type approved by DNV
- Procurement, spares, crewing, and HSSEQ in one system
- Onboard instances that work offline and reconcile with shore
EPC & Engineering Projects
Every drawing, revision, and approval, controlled.
For the owners, PMCs, EPC contractors, and consultants delivering major construction and engineering projects: one controlled document register, reviews and markup with coded dispositions, routed approvals, and formal transmittals — with a full audit trail from first submission to close-out.
- One register across every project party
- Reviews, markup, and coded dispositions
- Transmittals and a full audit trail
Beyond these industries
Beyond these three, we build selectively.
Retrotech does not market to every industry. When an operation outside these three runs on the same fundamentals — records that must be right, workflows that must be followed, approvals that must hold — our custom development practice takes it on, with the same discipline and the same accountability. That is how our invoice, property, and HR systems came to exist: not as a sideline, but as the same way of building, applied to a different operation.
