Offshore Analysis & Design


GT STRUDL offers powerful capabilities for offshore analysis and design. A set of integrated features enable the engineer to perform the complex functions of sea environmental load computation, fatigue life analysis, jacket pile foundation analysis, and code checking of offshore structural strength and performance behavior.


The computation of sea environmental loads is performed by the GTSELOS program. Various specialized analyses include the following:

  • Static and dynamic wave and wind load analyses of fixed and floating jacket and semi-submersible structures
  • Jacket launch analysis, including the effects of both barge and jacket motion
  • Jacket upending analysis
  • Jacket floating stability analysis

The sea environment loads computed by GTSELOS are then easily imported by GTSTRUDL, where they are used to perform fatigue life analysis, jacket pile foundation analysis, and code-checking procedures.

Fatigue Life Analysis

Fatigue life analysis can be performed by one or more of three methods, including the Discrete Probabilistic Method, the Power Spectral Density Method, and the simple Deterministic Method. The fatigue life analysis includes load-dependent joint classification analysis according to:

  • API and ISO standards
  • SCF factor computations based on the Kuang, Smedley, and Efthymiou equations
  • User-defined S-N fatigue data
  • Cumulative damage computation based on the appropriate application of the Palmgren-Miner Law

Pile-Structure Interaction Analysis

Pile-structure interaction analysis can be used for three-dimensional structures supported by nonlinear foundation pile members that are embedded in a nonlinear soil medium. The superstructure is described by a conventional GT STRUDL small deflection, linear elastic model. The pile-soil foundation can be modeled to include the:

  • Soil nonlinear bending, axial, and torsional properties
  • Inelastic load displacement properties of the pile
  • Beam-column effect of the pile
  • Ultimate axial capacity of the pile, taking into account skin friction along the pile

Code Checking

Standard tubular members can be checked according to the provisions of the latest API and ISO code provisions for:

  • Tension
  • Compression
  • Bending
  • Punching shear between brace and chord members
  • Hydrostatic collapse
Quality Assurance

GTS_Nuclear QA Graphic

Since 1983, the GT STRUDL quality assurance and quality control (QA/QC) program and procedures have been some of the industry’s most rigorous. They are in full compliance with applicable provisions of the U.S. NRC’s 10CFR21 and 10CFR50 Appendix B regulations. In addition, GT STRUDL QAQC procedures are in full conformance to the ASME NQA-1-2008, including the 2009 Addenda Subpart 2.7 (NQA-1a-2009).

Comprehensive QA/QC Program

The QA/QC program and procedures are routinely audited by independent auditors from nuclear industry corporate licensees several times each year. Auditors representing the Nuclear Procurement Issues Committee (NUPIC) and the Nuclear Industry Assessment Committee (NIAC) conduct audits every three years. Each new version of GT STRUDL is thoroughly validated and verified (V&V) for its computational quality and performance with approximately 5,000 V&V test problems.

The combination of GT STRUDL's QA/QC procedures along with its advanced linear and nonlinear analysis capabilities, computational speed, steel and reinforced concrete design, extensive collection of comprehensive detailed user documentation, and technical support services makes GT STRUDL ideal for use in the worldwide process, power, marine, and other general structural engineering industries.
