  • Pressure Containment (Bursting)
  • Local Buckling (General); which comprise of:
  • Local Buckling External Overpressure only (System Collapse)
  • Propagation Buckling
  • Local Buckling (Combined Loading Criteria). This may be Load or Displacement Controlled.
  • DNV-OS-F101 (2001) Submarine Pipeline Systems;
  • ASME B31.4 (2001) American Society of Mechanical Engineers, Gas Transmission and Distribution Piping Systems;
  • ASME B31.8 (2007) American Society of Mechanical Engineers, Liquid Transportation Systems for Hydrocarbons, Liquid Petroleum Gas, Anhydrous
  • Ammonia, and Alcohols;
  • Provide data for screening of observed span length
  • Evaluate allowable span length
  • Static stresses due to bending under lateral loads in the extreme storm conditions. The loading on the span includes self weight, buoyancy and maximum steady state hydrodynamic loading
  • Assessment of the risk of vortex-induced vibrations by the use of simple “reduced velocity” method.
  • Determining concrete thickness for a pipe specification;
  • Determining wall thickness to achieve a specified safety factor;
  • Determining a safety factor for a specific pipe input
  • Batch processing several analyses for different water-depths, currents and wave profiles.
  • Determine concrete thickness for a pipe specification;
  • Determine a required wall thickness to ensure stability;
  • Calculate the safety factor between submerged weight as specified and that required for stability.
  • Determine whether the pipeline is susceptible to upheaval buckling;
  • Evaluate the required height of backfill to prevent upheaval buckling.
  • The Pipeline is trenched for protection, therefore preventing lateral movement;
  • Submerged weights are low since concrete is often necessary for stability;
  • The contents temperatures are high and Pipeline flexibility is high.
  • The UPBK module enables the engineer to quickly and easily carry out upheaval buckling calculation. This in turn allows flexibility in conceptual design and assessment of the pipeline for a range of operational and environmental conditions.
  • API 1111 (2009, Errata 2011) – American Petroleum Institute (Design of Offshore Hydrocarbon Pipelines);
  • ASME (B31.4: Liquid, B31.8: Gas) – American Society of Mechanical Engineers, Pipeline Transportation Systems for Liquid Hydrocarbons & Gas
  • Transmission and Distribution Piping Systems;
  • DNV 1981 – Det Norske Veritas (Rules for Submarine Pipeline Systems);
  • BS PD8010 (2004) – Code of Practice for Pipelines (Part 2: Subsea Pipelines);
  • BS8010 (1993) – British Standard, Code of Practice for Pipelines Part 3 (Pipelines Subsea).
  • Calculate the minimum wall thickness for each of the selected design code requirements (hoop stress, hydrostatic collapse, buckle propagation, diameter to thickness ratio);
  • Select the minimum wall thickness that will comply with all the selected design code requirements;
  • Recommend the nearest API pipe size that will comply with all the selected design code requirements.
  • Calculate the thermal, pressure, frictional and total strain at each node along the pipeline;
  • Calculate the displacement of both the hot and cold ends of the pipeline (this takes into account the variation of temperature and pressure profile along the length);
  • Calculate the maximum and minimum stresses at the nodal points.
