PIONEERING DESIGN WITH SESAMCustomer story – Aibel
Aibel AS has used DNV GL’s Sesam software for as long as the company has existed. The current innovative DolWin Beta wind platform is designed using Sesam for fixed structures.
SOFTWARE – SESAM™
DNV GL AS, [email protected], www.dnvgl.com/software October 2017
DolWin Beta will be towed into the right position and placed on the sea bed. It has separate living quarters for 24 people, a helipad and two lifting cranes. The platform is being built by a subcontractor in Dubai and will be fitted out at the Aibel yard in Haugesund, then towed out to the German DolWin field. Sesam’s fem software is used on DolWin Beta for structural and ballast analyses.
“The program covers the offshore segment well. DNV GL under-stands the challenges of the offshore industry. Many of the offshore companies have a close working relationship with DNV GL. And when we need support, DNV GL is focused on helping us with a solution,” says Mr Høeg.
“There is a certain level of proficiency that our engineers have to reach in order to fully utilize the program, but when they have learned it they can make use of powerful and efficient software,” he says. The efficiency is heightened when several users can work on a model. Using Sesam for fixed structures, it’s possible to perform analysis on separate parts of a structure, which saves time in comparison to modelling the entire structure.
The reporting functions have also advanced in recent years, and it is possible now to transfer information directly from the analyses to a report.
Aibel does not use a third party modelling tool in dialogue with GeniE, but Høeg says this may change in the future. Currently they use a different program for non-linear analysis, and the information is transferred routinely from Sesam.
