The physical systems — and the procedures wrapped around them — that keep third-party product safe, segregated and verifiable.
Asset Systems
Seven Systems, One Standard
Terminal infrastructure is only as credible as the procedures that operate it. Each system below is described with the operational controls a counterparty's inspector would ask about.

01
Storage Tank Systems
Tankage is the core asset class of any terminal. Tanks are selected and operated by service: floating-roof units for crude oil and volatile white products, where the roof rides on the product surface to minimize vapor space and evaporative loss; fixed-roof units — often insulated and fitted with heating coils or external heat exchangers — for fuel oil, bitumen feedstocks and other heated service.
Each tank operates within a defined envelope: maximum safe filling height, minimum operating heel, pumpable volumes and roof-landing limits for floating-roof units. Levels are monitored continuously by radar or servo gauging with independent high-level alarms and overfill protection in line with recognized overfill-prevention practice.

Heating & circulation capability heating and circulation for viscous grades
Radar / servo gauging with independent overfill protection
Secondary containment: bunded compounds sized to tank capacity
02
Manifold Systems
The manifold is the terminal's switching yard: a valve matrix that routes product between berths, pipelines, tank groups and loading gantries. Every movement is executed against a written, verified line-up — the sequence of valves opened and closed for that specific transfer — and isolated from all other services by double block-and-bleed arrangements.
Dedicated manifold segments are assigned by product family to prevent cross-contact between incompatible grades, and line-ups are independently checked before any pump start.

Product Segregation
Segregation protects the single most valuable property of stored product: its specification. The terminal maintains segregation at three levels — dedicated tankage per grade family, dedicated or verifiably cleared transfer lines, and procedural controls covering line displacement, interface cuts and first-fill sampling after any service change.
Where a tank or line changes service, the change follows a documented product-change procedure including cleaning verification and a first-receipt quality check before the new grade is accepted.

Transfer Operations
Transfers — tank-to-tank, tank-to-berth, berth-to-tank — are planned movements with a nominated quantity, verified line-up, agreed pumping rates and defined start/stop communication. During transfer, operators monitor levels at both ends, line pressures and pump performance; any discrepancy between dispatched and received volume beyond tolerance triggers an immediate stop and investigation.

05
Pipeline Connectivity
Pipeline interfaces connect the terminal to refineries, other terminals or national grids. Receipts and deliveries across a pipeline interface pass through custody metering — proved flow meters or verified tank gauging — with quantities reconciled against the counterparty's figures for every batch and documented in signed meter or gauge tickets.

Marine Loading Facilities
The marine interface is operated to the ship–shore standards of ISGOTT (International Safety Guide for Oil Tankers and Terminals). Every vessel call proceeds through pre-arrival vetting and exchange of information, a jointly completed ship/shore safety checklist, agreed transfer rates and emergency shutdown criteria, and continuous watch during cargo operations.
Berth specifications — draft, LOA, displacement limits and manifold arrangements — are published per terminal published berth specifications and made available to scheduling counterparties and agents.
Custody is the discipline that lets a customer prove, at any time, how much product is held and in what condition. Opening and closing quantities for every movement are established by static tank gauging or proved meters; samples are drawn, sealed and retained at agreed points; and independent surveyors appointed by cargo interests have access to witness gauging, sampling and calculations.
Quantities are computed under recognized API MPMS / ISO measurement standards and recorded in signed documentation issued to the customer — the working paper trail of ownership.
