Tank Cleaning & Calibration
Danholsen Global Services Limited (DGSL) delivers integrated tank cleaning and calibration services designed to improve storage safety, measurement accuracy, and operational performance across oil and gas facilities. Our execution model combines controlled decontamination workflows with high-precision dimensional assessment.
We support vertical, horizontal, floating roof, spherical, and other industrial storage tanks, delivering technically defensible outputs for maintenance planning, inventory management, and compliance verification.
Industrial Tank Cleaning Operations
Using specialised equipment and controlled entry procedures, we remove sludge, hydrocarbon residues, and contaminants to restore tanks to safe operational condition while reducing inspection and maintenance constraints.
Volumetric Calibration & Tank Table Development
Our calibration scope includes generation of accurate volumetric tables from field measurements, supporting dependable stock accounting, reconciliation control, and custody-transfer confidence.
Dimensional & Geometric Integrity Assessment
DGSL performs wall verticality checks, roundness and shape analysis, plus roof and floor profile evaluation to identify geometry deviations that influence capacity calculations and asset condition.
Technical Reporting & Decision Support
We provide clear, data-driven reporting packages that convert field findings into actionable maintenance priorities, helping clients optimise interventions and extend tank service life.

Related Questions to Service
Why should tank cleaning and calibration be integrated?
Integrated delivery reduces downtime and improves data quality because calibration is performed after contamination effects are addressed, giving more reliable geometric and volumetric measurement outcomes.
Which tank types does DGSL support?
We support vertical, horizontal, floating roof, spherical, and other industrial storage systems, with service methodology tailored to tank geometry, product type, and operating constraints.
What technical deliverables are provided after calibration?
We provide volumetric tank tables, dimensional checks, verticality and roundness analysis, roof and floor profile results, and clear report summaries to support engineering and operations decisions.
How do you manage safety during tank cleaning activities?
DGSL applies controlled entry protocols, gas testing, isolation verification, and supervised work execution to maintain safe conditions for personnel and assets throughout the cleaning process.
Can you support both one-off scopes and long-term maintenance programs?
Absolutely. We execute single campaign scopes and recurring service programs with planned reporting cycles, helping clients sustain performance and regulatory confidence over time.
