Customer story – Aibel
Aibel AS has used DNV GL’s Sesam GeniE for as long as the company has existed. The current innovative
DolWin Beta wind platform is designed using Sesam GeniE.
“DNV GL - Software understands the customers and the challenges in the offshore market,” says Ragnar Høeg, Section Manager
Structural, Architect & Marine in Aibel. “We use Sesam GeniE on
all main load-bearing structures.” In addition, the software is used
for processing units and FPSOs.
Currently Aibel has 30 user licences for Sesam GeniE. “We’ve
used Sesam as long as we’ve existed as a company. Personally,
I’ve used the Sesam since 1990, and there are some people here
who have used it since the 1980s,” he says. Mr Høeg has worked
at Aibel and its predecessor ABB Offshore Systems, for 16 years.
The main use of Sesam GeniE at Aibel is on oil platform newbuilds, mostly for fixed structures and jackets. An example is the
Gudrun project, where Aibel used Sesam GeniE during the building of a 10,000 ton topside finished in 2013.
The DolWin Beta project is also built using Sesam GeniE. DolWin
is a collaboration project between Aibel and ABB, a self installing
GBS that will serve a large wind farm cluster in the German sector
of the North Sea. It will receive alternating current from the wind
farms, converting it into direct current before sending it onshore
through subsea cables. Aibel is designing and building the plat-

form, while ABB has project responsibility and is supplying cables
and conversion equipment.
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
GeniE is used on DolWin Beta for structural and ballast analyses.
“The program covers the offshore segment well. DNV GL understands 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 GeniE, 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 GeniE.
DolWin Beta It will receive alternating current from wind farms, and
convert it into direct current before sending it onshore via subsea cables.
It will have a capacity of 924 MW and can receive electricity from three
wind farms, i.e. a total of 240 turbines. It is the size of a football field.
