Closed Sampling · Since 2006

Samples without vapour.
Measurements without the mess.

Tank-Eye builds certified closed-loop sampling and inspection systems for hydrocarbon pipelines, barges and storage tanks. No dampening, no exposure, no compromise — from the North Sea to the Gulf.

Why closed sampling

Open sampling costs more than money. It costs air, time and people.

Every time a tank is opened to be measured, hydrocarbon vapour escapes and the inspector breathes it. Tank-Eye replaces that with a certified vapour lock: precise, auditable, and safer for the crew.

01 — Safe

Zero vapour exposure, by design.

A gas-tight vapour lock valve isolates the tank from the atmosphere during measurement and sampling — no fumes, no ignition risk, no confined-entry permit.

02 — Precise

Measurements you can defend in court.

Level, temperature, free-water, density and full chemical composition — captured under controlled pressure, compliant with API 8.2, ISO 3171 and Norsok I-105.

03 — Sustainable

Diesel-free, fugitive-emission-free.

One barge retrofitted with Tank-Eye saves roughly €5,850 in diesel per year and removes the need for standby engines during routine inspection — a quiet, measurable decarbonisation win.

What we sample

From barge to refinery, virtually any hydrocarbon stream.

Built to the standards that matter

Four codes, one certified valve.

Every Tank-Eye system is designed to meet the reference standards used by auditors, custody-transfer operators and national petroleum inspectorates.
