Costly checks can be eliminated thanks to the integrated RIB solution, as with iTWO we all work in one system – from system engineers to tendering management
The Energy Management division of Siemens AG, headquartered in the Franconian city of Erlangen, is one of the leading worldwide providers of products, systems and solutions for the transmission and distribution of electricity. The division supports the development and extension of an efficient energy infrastructure for energy suppliers and industry. 52,000 employees work for Siemens Energy Management worldwide on around 100 production and construction sites.
They include Energy Management Division Transmission Solutions: A team of experts focusing on planning, erection, maintenance and repair of high-voltage facilities and direct current transmission technologies (HVDC facilities) across the globe. They steer the successful realization of projects such as the plant commissioned by Joint Venture Nemo Link for a maritime cable connection of over 140 kilometers between Great Britain and Belgium. Nemo Link is a partnership between national energy suppliers from both countries. The HVDC plant, currently under construction, is designed for a power of 1,000 megawatt and is a symmetrical, monopolar system for +/- 400 kilovolt direct current. Nemo link is a showcase project for an integrated energy market within Europe. The new network is intended not just to improve energy supply in both countries, but also to contribute to the integration of renewable energies.
In the field of cost management, the Transmission Solutions department has relied on software systems from RIB for more than ten years. First, the software was only used for the creation of calls for tender and price comparisons. After a few years, all calculation, including bid creation, in the assembly and repair disciplines, was carried out with RIB software. “When constructing high-voltage plants on the scale of the Nemo Link project, the number of participants adding costs into the system and the number of details within the overall calculations represent a significant challenge,” acknowledges Kai Herrmann, iTWO Program Manager at Energy Management Transmission Solutions. “For this reason, we started introducing iTWO by RIB in the sector already in 2015, with the goal of thoroughly integrating the software solution. The system won us over and has in the meantime found deployment in Great Britain and India, as well as in Germany,” he continues.
In the past, we did this work with many smaller tables. The problem: All details for the overall calculation were manually transferred, meaning errors could easily slip in
In the course of the analysis of the company and project processes for the new iTWO solution, 2-day workshops with the software supplier took place every 14 days during the first few months. As time went on, the 400 employees, who now all work with the new software, were introduced to the functionalities of the system and learned at the same time a method for optimized calculation which extends over the entire plant engineering project. “In the past, we did this work with many smaller tables. The problem: All details for the overall calculation were manually transferred, meaning errors could easily slip in,” explains Herrmann. “Costly checks can be eliminated thanks to the integrated RIB solution, as with iTWO we all work in one system – from system engineers to tendering management,” he continues. The advantages are obvious: Even detailed information can be easily found. There is no longer a need to trawl through individual software tools. The team at Energy Management Transmission Solutions uses circuit meetings to work together on the project – within a software system. “All in all, the quality of collaboration has markedly improved with RIB,” Kai Herrmann concludes.
> high transparency in the planning process
> improved coordination of all involved in planning
> BIM as an all-encompassing method ensures quality in the project
