With its team of specialists, Sigma Solutions can accommodate a variety of needs, including but not limited to the following:

Tank Cleaning

Our confined space entry teams provide tank cleaning services for…

  • Tank Farms
  • Product Terminals
  • Power Plants
  • Refineries
  • Industrial

Tank cleaning projects can be extremely complicated and difficult to assess. At Sigma Solutions, tank and other confined space cleaning are core competencies…not filler time for some other primary service focus. There is no single best method for implementation, and mistakes can be costly…both for the tank owner and the tank cleaning contractor. Each project has to be carefully evaluated to determine the most economical and practical approach contingent on all relevant issues (e.g., worker safety, required degree of cleanliness, out-of-service constraints, quantity, quality, and viscosity of residual product, etc.).

Whether it is a single tank, multiple tanks, an entire tank farm, or a terminal to be decommissioned, Sigma Solutions has the trained personnel and equipment to help accomplish the project and all related tasks…at a cost effective turnkey price. Our experience runs deep with assignments that have been influenced by:

  • Augmentation of storage capacity
  • Product type change
  • API 653 internal inspections
  • Repairs and/or modifications
  • Decommissioning or demolition

As warranted, all confined space entry activities are conducted with appropriate secondary containment. Additionally, special attention is given to on-site monitoring of weather conditions prior to and during the execution of projects and the assessment of such factors as temperature, relative humidity, heat index, wind direction & velocity, and barometric pressure.
