Tekla Structures in practice:<br />
<strong>SAIPEM</strong> <strong>offshore</strong>
At work with<br />
SAipem<br />
<strong>offshore</strong><br />
a In 2002 Saipem and Tekla joined on<br />
a technical project to get Saipem’s Offshore<br />
division started in using the Tekla Structures<br />
software. The technical team at Harpaceas<br />
(Tekla’s reseller in Italy) first worked with<br />
Saipem’s design teams in San Donato Milanese<br />
to determine the relevant technical issues<br />
in this critical design sector. They then<br />
cooperated directly with Tekla’s development<br />
teams to develop a customized application<br />
and also used their own development<br />
resources based in Italy. This process<br />
achieved defined results in a relatively short<br />
time, and today, the configuration of Tekla<br />
Structures used by Saipem includes a series<br />
of additional features created specifically to<br />
allow management of <strong>offshore</strong> design project.<br />
With Tekla’s open solution, Saipem was able<br />
to generate added value by exploiting its own<br />
design organization.
The Halfdan<br />
platform<br />
s Halfdan BB is an unmanned<br />
platform situated in the North<br />
Sea at a location where the<br />
depth reaches 50 m. The<br />
platform’s substructure consists<br />
of traditional tubular cable<br />
profiles which are welded together to form a tower lattice<br />
with three arms joined below to the foundation pylons.<br />
The deck is supported by the jacket’s three pillars which<br />
are spaced apart at a distance of 18 m. All of the technical<br />
equipment is situated on the deck along with the platform’s<br />
auxiliary services. The platform also supports a bridge to the<br />
other two platforms installed in the same area.<br />
The design of the deck structure was done with Tekla<br />
Structures right from the early stages of the project.<br />
Modeling began with the main steel structure as soon as<br />
the calculations were completed on the computer. The<br />
model encompassed all of the reinforcements and minor<br />
elements such as the connecting joints welded between the<br />
main beams. As soon as information about the equipment<br />
was available, the designers moved on successively to the<br />
secondary structures with all of the required detailing.<br />
The Tekla Structures model was used successfully for various<br />
purposes:<br />
- Continuous monitoring of the weight of the structure<br />
and the position of the deck structure’s center of gravity<br />
during the design phase<br />
- Output of 2D drawings to present to the end client and<br />
the relevant authorities for certification purposes<br />
- Output of lists of materials to obtain the necessary<br />
materials<br />
- Updating of the structure using the 3D model to identify<br />
and correct any conflicts with the equipment, piping,<br />
cables, access routes, etc.<br />
- Output of 2D drawings for developing the workshop<br />
designs used on the construction site
a “We believe that in the future, Tekla Structures<br />
will contribute to further boosting the efficiency<br />
of our work processes as well as the quality of<br />
the results that can be derived from the model.“<br />
– Giuseppe Frigerio, Engineer at Saipem<br />
The Awa-Paloukou<br />
platform<br />
s The Awa platform is a structure used to extract fuel oil<br />
with 12 slots. It is installed <strong>offshore</strong> from Congo at a depth<br />
of about 76 m. The jacket consists of a frame structure<br />
with four arms which are positioned over four preinstalled<br />
foundation pylons and securely attached to them. The deck<br />
is supported on the four arms of the jacket. Its total weight<br />
during operating conditions is about 3000 t. On the western<br />
side of the deck, a cantilever flare extends over about 60<br />
m. Tekla Structures was used to model the entire structure<br />
including the jacket, deck and flare. The 3D model of the<br />
entire platform was also used to characterize all of the other<br />
structural components, provide lists of needed materials,<br />
monitor the weight and the position of the center of gravity,<br />
and prepare the project plans and workshop detailing.
Why Saipem chose Tekla<br />
Structures<br />
Saipem’s Offshore division has now used Tekla Structures<br />
to design its platforms for two years. “Clearly, the most<br />
significant benefit is the availability of a single structural<br />
model from which we can extract project plans and<br />
detailing, lists of materials, weights and centers of gravity.<br />
The software also allows direct interfacing to the piping<br />
model in PDS,” noted engineer Giuseppe Frigerio, Engineer<br />
at Saipem.<br />
“The program was customized to handle our needs related<br />
to material management, construction phase management<br />
and integration with corporate standards (standard joint<br />
macros and customized user attributesand material lists).<br />
Another useful function provided by Tekla Structures is<br />
simultaneous access by multiple users to the same model.”<br />
“Modeling the design of an entire platform with small<br />
dimensions, such as Maamoura, required a single designer<br />
for the deck and another designer for the<br />
jacket. Without Tekla Structures, we would<br />
have definitely needed one more designer.”<br />
“However, the greatest benefit of using Tekla Structures<br />
lies in the ability to oversee the whole project since all of<br />
the information is encompassed in the model. This is also<br />
true of the execution of feasibility studies and initial steps,<br />
assessment and evaluation of weights and centers of gravity<br />
and the speed of verification of project variations over the<br />
course of the work.”<br />
“We believe that in the future, Tekla Structures will<br />
contribute to further boosting the efficiency of our work<br />
processes as well as the quality of the results that can be<br />
derived from the model,” concluded Frigerio.<br />
Saipem<br />
Crossing ocean and sea, Saipem’s <strong>offshore</strong><br />
activities division has built a global reputation<br />
as one of the true innovators in its field. Since<br />
the late 1950s, the company has continually<br />
updated and advanced its capabilities to<br />
anticipate the ever greater demands of the<br />
market. Saipem’s pioneering work in pipeline<br />
installation is matched by its experience<br />
installing <strong>offshore</strong> platforms around the world,<br />
mastering both the heavy lift and the floatover<br />
techniques.<br />
Over the last ten years, Saipem has<br />
completed some 120 <strong>offshore</strong> construction<br />
projects – including modular deck drilling<br />
and production platforms, integrated deck<br />
platforms, wellhead platforms, accommodation<br />
platforms, FPSOs – often, and increasingly<br />
so, in an integrated contractor role. Current<br />
potential of Saipem fabrication facilities<br />
exceeds an aggregate of 130,000 t per annum.
