When designing and modifying offshore structures, taking wind loads on equipment into account has been a complicated task for engineers. The new release of DNV GL’s Sesam GeniE software includes cutting-edge technology for wind analysis, allowing designers to achieve more accurate results in significantly less time, thereby reducing costs.
The wind loads on large equipment and living quarters installed on for example jackets, must be taken into account when performing strength assessment for the structure. With the new Sesam GeniE 6.7, the software can analyse these loads, automatically calculating new loads, including suction, when wind strength and direction is re-specified. "This allows engineers to determine the combined forces in effect on beams and walls, and is especially useful when structures are modified and equipment is moved. This capability is unique for Sesam, and confirms our position as the leading provider of software for design and engineering of offshore structures. This is truly about managing risk," says DNV GL – Software managing director Are Føllesdal Tjønn.
Previously, engineers would have a time-consuming task when calculating moved equipment, having to redo the analysis from the start. Sesam GeniE will take the moves into account and recalculate automatically, says Ole Jan Nekstad, Sesam Product Director at DNV GL – Software.
Sesam GeniE version 6.7: several new features
The new release of Sesam GeniE includes many new features, especially for analysis of jackets, including expanded code check features. Users can now define code checking details on the structure, and not only on a capacity member.
Another important development is the possibility to import models from SACS, something that will give users full flexibility when choosing their preferred software for modification and requalification, allowing them to benefit from the advanced graphic and modelling capabilities of Sesam GeniE.
The new release also includes improvements in tension/compression analysis – with the possibility to calculate wave loads under water. It also includes code checking of grouted and double-skinned joints, leading to possible cost savings with less steel used in the design of tubular joints.
It is also easier now to include coefficients on clean and ‘fouled’ (i.e. surface has been subject to marine growth) members, with automatic analysis based on the parameters given. Here it is also possible to import data from SACS.
