General tab

The General tab includes the 4 following frames:

  • Type of analysis

  • Calculation method

  • Type of line

  • Results storage options

Details on the behavior of the tab are given below.

Type of Analysis

This frame includes 3 radio-buttons used to select which type of post- processing is to be performed between Spectrum response analysis, Fatigue Analysis, and Loads Histograms.

The other 3 main tab sheets and other frames from the General tab shall display dynamically as a function of the Type of Analysis option selected.

Calculation method

The user must select either:

Type of line

In this frame, you may select the type of line on which the fatigue analysis will be carried on. Available types of lines for fatigue post-processing include Steel risers, Anchor legs and Bounded flexible hoses. The type of line will then drive whether the calculation of damage must be done based on S-N or T-N curves, and whether stress will be calculated considering a Rigid Pipe type or Flexible Hose type.

More details for fatigue on Anchor leg (SN curves) can be can be found here.

The Tubular joints - Connections (by subjoint) section gives information on how to perform fatigue on tubular intersections by subjoint with calculated or user-defined SCF.

Result saving parameters

Select either the Save full database or Save RAOs (if computed) options.
