A plate field optimization tool for offshore structures according to DNVGL standards

Project description

ANYstructure is a GUI based steel dimesion calculation and weight optimization tool intended for naval architects. It is based on DNVGL-OS-C101 Design of offshore steel structures, general - LRFD method.

The following is caluculated:

  • Minimum section module for stiffener
  • Minimum plate thickness
  • Buckling capacity (DNV-RP-C201 Buckling Strength of Plated Structures)
  • Plate/stiffener connection fatigue (DNV-RP-C203: Fatigue Design of Offshore Steel Structures)
  • Bow slamming according to DNVGL ship rules

In an optimization process all these can be acconuted for or individually turned off.

Loads are defined as follows:

  • External surface loads defined by polynominal equations
  • Tank loads are calculated automatically

Loads are combined according to DNVGL-OS-C101.


The easiest way to install the package is via pip:

$ pip install anystructure


An entry point is defined. After installing on PIP, just type “ANYstructure” in the command window.

Alternatively run
