SESAM Xtract (Ceetron, DNV GL)

January 31, 2019

Post-processing of hydrodynamic and structural analyses


DNV GL’s SESAM software package is recognized as one the most advanced and comprehensive software systems for structural and hydrodynamic analysis available to the offshore and maritime industry.


In 1999, DNV GL Software decided to enter a collaboration with Ceetron AS to develop a customized post-processor for SESAM. The new software, named Xtract, was designed as a replacement for SESAM Viewer and SESAM Postfem. The objective with the product was to offer to the market a high-performance general purpose visualization program for animation and presentation of results from various hydrodynamic, static, and dynamic structural analyses. The graphics were to support highly interactive work sessions and navigation of super-element hierarchy, result cases, result attributes (e.g. displacements and stresses), and sets.


The Ceetron Solutions team has designed and implemented Xtract - formerly as employees of Ceetron AS – and from 2013 as subcontractor to Ceetron AS. The development work was based on GLview 3D Visualization API, Ceetron’s second- generation development toolkit for 3D visualization and interpretation of CAE data. Following the first release in September 2000, SESAM Xtract has since been updated on a yearly basis.


Driven by its purpose of safeguarding life, property and the environment, DNV GL enables organizations to enhance the safety and sustainability of their business through delivery of services and software. They conduct their business in the maritime, the oil & gas, and the energy industries. They operate from more than 400 offices in more than 100 countries, and approximately 16,000 employees. Annual revenues are around NOK 22b (2014).
