Calculate Pipeline Requirements: Wall Thickness Estimator

Design safer pipelines, risers and jumpers with accurate wall thickness calculations. 

• What you can do

  • Determine required pipeline, riser and jumper wall thickness based on industry standards
  • Calculate specifications for rigid pipelines, risers, and jumpers
  • Apply either API RP 1111 (4th Edition) or DNVGL OS-F101 (2013 Edition) guidelines
  • Account for both burst and collapse design load cases
  • Transfer calculated values directly to your connection's metadata
• How it works

  The Wall Thickness Estimator is built into FieldTwin, calculating optimal pipeline specifications based on your project parameters:

  Project Level Parameters: Use default engineering values for steel properties (Modulus of Elasticity, Poisson's ratio) and environmental factors (seawater density, gravitational acceleration)

  Elevation Reference: Set your reference height where maximum design pressure is specified (typically a platform location above mean sea level)

  Connection-Specific Inputs: Enter eight key values for each connection:

  • Maximum Design Pressure
  • Maximum Design Temperature
  • Connection Outer Diameter
  • Minimum Internal Pressure
  • Pipe Corrosion Allowance
  • Pipe Grade (X60, X65, etc.)
  • Fabrication Process
  • Service Type (Oil, Gas Injection, Water Injection, etc.)
• Getting results

  • The module calculates two thickness values - one for burst scenarios and one for collapse scenarios
  • The larger of these two values is automatically selected as the recommended wall thickness
  • You can transfer the calculated value directly to your connection's metadata with one click
  • Choose which design code (API or DNVGL) to apply to your final selection
