Tank Terminal & Tank Farm Surveys

A tank terminal or tank farm can be rapidly and accurately mapped using the latest surveying technology. You may be managing multiple tanks of different sizes, ages, products and priorities, all within a shared bund and site layout.

Running an effective integrity, calibration, or maintenance programme across a whole facility requires a survey partner who can deliver consistent, comparable data across every asset, year after year. We work with both new and existing terminals – whether you are planning a build-out or managing a long-established site.

At Storage Tank Surveys, our teams use laser scanning and UAV technology to capture full facility geometry quickly, safely and with minimum disruption to your operation.

What We Survey Across a Terminal

Our terminal and tank farm survey programmes cover the full range of dimensional work, across every tank and much of the supporting infrastructure. Typical scope includes:

  • Shell deformation, roundness and verticality for every tank
  • Tank floor inspection and settlement surveys – foundation and differential settlement
  • Roof alignment and rim seal geometry for floating roof tanks
  • Calibration and volumetric data for inventory management and custody transfer
  • Bund capacity and containment volume modelling for the entire facility
  • 3D modelling of pipelines, manifolds and site layout for dimensional control
  • Historical comparison across successive surveys

Every tank gets the same treatment, so when your integrity, operations and compliance teams come to look at the data, they’re comparing like with like.

Coordinated Survey Programmes

When you appoint Storage Tank Surveys as a single partner across a terminal, you gain consistency that’s difficult to achieve with multiple providers. One methodology. One reporting format. One dataset structure. Across every tank on the site.

That consistency matters. It makes it dramatically easier to:

  • Compare tanks against each other and prioritise maintenance work
  • Plan inspection cycles at a facility level, not a tank-by-tank level
  • Track movement, deformation and settlement over time
  • Integrate survey data into your asset integrity and management systems
  • Brief incoming inspection bodies or engineering consultants

Our Methodology

Technology Suited To Large Sites

We use high-accuracy laser scanners and UAV drones to capture the full 3D geometry of large facilities in a fraction of the time traditional methods require. The approach minimises personnel on site and reduces disruption to operations – important considerations at live terminals where product turnover and safety constraints often make scaffolding or confined space entry impractical.

The resulting point cloud data is a complete, auditable record of every tank at a given point in time. The same dataset supports calibration, deformation, bund volume and 3D modelling work, so one site visit delivers multiple outputs.

Supporting Integrity & Compliance Programmes

Multi-tank facilities operate under demanding regulatory frameworks, including COMAH in the UK, and industry standards such as API 653, EEMUA 159 and EN 14015.

Our dimensional survey data provides the accurate geometric inputs – shell geometry, settlement, verticality, and bund capacity – that your engineers, inspection bodies and competent authority use to support their integrity and compliance assessments. We are not an inspection body, and we do not determine compliance; our role is to make sure the data behind those assessments is as accurate and auditable as it can be.

Frequently Asked Questions

How long does a tank terminal survey take?

It depends on the size of the facility and the scope of the survey. A mid-sized terminal can typically be surveyed in a matter of days using laser scanning; traditional methods would take significantly longer.

Can you survey a terminal without shutting it down?

In most cases, yes. External laser scanning can generally be carried out while tanks remain in service, and we plan surveys around your operational and safety constraints.

Can you compare the current data with previous surveys of the same terminal?

Yes. Where previous survey data is available, whether ours or from another provider, we carry out differential analysis to track movement, deformation and settlement over time.

Can you compare the current survey data with previous EEMUA 159 surveys?

Yes. Where previous survey data is available, whether ours or from another provider, we carry out differential analysis to track movement, deformation and settlement over time.
