50 years of experience in developing quality software has led to the most flexible solution for integrating engineering tasks, applications and results.

Key challenges
The demand for faster design of offshore structures has increased during the past decade, with many operators wanting to fast-track field installations. Yet worldwide yard capacity is strained, and there is a lack of engineering resources in a globally distributed working environment.

When designing offshore structures, all life-cycle stages need to be considered. Traditionally this has involved a broad variety of computer-aided engineering tools and associated data models. Valuable time is lost by making several data models of the same structure, and in learning different software tools. Furthermore, the lack of data integration between software tools prevents efficient design iterations, as it is necessary to modify the various data models and perform re-analysis for each project revision.

Our innovation
Sesam Fixed Structures is a complete toolkit for performing hydrodynamic, pile/soil and structural strength analysis, and design tasks such as fatigue and code checking covering the stages in a structure’s lifetime. This leads to enhanced quality, reduced software costs and reduced need for training. Concept technologies in computeraided engineering have proven to be costefficient in all life-cycle phases, as one unique concept model can be used with different complexities to create different analysis representations. This efficiently assesses the structure in different stages by analysing various parts of the structure with different boundary conditions – all from the same model. Another major benefit is that concept technologies lead to faster design iterations. By modelling your experiences in a workflow modelling system, it is possible to share them as templates to the entire organisation. This leads to standardisation of work processes, reduced learning curve and increased quality. Sesam Fixed Structures covers all aspects needed to document a safe design – from modelling through analysis to results assessments for the entire life cycle.
