Challenging tunnel rehabilitation work well underway

more

Work at the Weissenstein Tunnel (SUI) construction site is progressing at full speed.
The first sections of the damaged masonry vault have been successfully removed and secured as part of the localized complete rehabilitation of the vault.
The most challenging part of the work is the complex geological conditions and the partially unknown conditions outside the existing masonry. The parts of the masonry vault that have been removed are located in the Opalinus Clay section of the railway tunnel – the geologically most challenging section. Differing conditions, fault zones and brittle conditions in the first section of the Opalinus Clay in the Folded Jura make tunneling difficult in this section.

As part of the rehabilitation work on the Weissenstein Tunnel, localized partial and complete rehabilitation of the vault is being carried out in various sections of the tunnel, and the tunnel drainage system, cable systems, safety installations and railway track running through the tunnel are being renewed. Two existing stations are also being modernized to meet the provisions of the Swiss Disability Discrimination Act.

IG WST (ILF Consulting Engineers in Switzerland and Emch+Berger AG Bern) has been commissioned by the sole contractor – the joint venture ARGE EWT (PORR Group and fretus ag) – as the “Tunnel and Stations Project Manager”, responsible for all rehabilitation works in the tunnel and the stations.

Innovative hydrogen project “mosaHYc” for a sustainable future!

more

Being a project between France, Germany and Luxembourg,”mosaHYc” (Moselle-Saar-Hydrogen-Conversion) is a European and pioneering cross-border project in the Grande Région, aimed at providing an initial and innovative infrastructure for the transport of hydrogen across borders. Thus Creos’ and GRTgaz’s mosaHYc project constitutes an essential link to bring together hydrogen producers and users in this region. With a 90 km long pipeline, hydrogen can be used as fuel and energy carrier for the industry, for mobility, reconversion and heat in the Grande Région, thus saving almost one million tons of CO2 per year. It is an important step to achieve the climate targets for 2030, 2040 and 2045!
To this end, about 70 kilometers of existing gas pipelines, some of which are no longer in operation, are to be converted into hydrogen pipelines. By additionally constructing about 20 kilometers of new hydrogen pipelines, the first hydrogen island network will be created.

We are delighted to be part of the planning and design of this innovative project with our team.
Our experts work on the preparation of the detailed design ready for implementation and on obtaining planning approval from the authorities for the construction of the hydrogen pipeline in the Leidingen-Dillingen section.

The start of the planning approval procedure is scheduled for early 2025. After the start of operation in 2027, the island network will have a capacity of up to 120,00 m3/h, depending on the maximum operating pressure.
mosaHYc is an example of a hydrogen infrastructure that extends beyond national borders.

Progress on the longest road tunnel in the Alps

more

Work on the construction site of the Gotthard road tunnel – the 2nd tube – in Switzerland is running at full speed. In early May 2024, work in the northern fault zone was initiated by starting construction lot 241, and thus the next important construction phase.
The northern fault zone is an approx. 300 m long section, characterised by weak kakirites in the Urseren zone, at the transition from the Mesozoic to the Permo-Carboniferous. It is located about 4.5 km from the northern portal.

The northern fault zone is excavated prior to the main excavation so that the shield TBM coming from the north can be pushed through. Advance takes place using NATM with full-face excavation. The tunnel face, which has an excavation diameter of 15 m, is divided into a maximum of 8 partial areas and systematically supported by using face bolts. Due to the squeezing rock mass behaviour, yielding support is installed, allowing controlled convergence of the profile before it is fastened. The excavation works are expected to continue until the end of 2025.

The joint venture Nuovo Gottardo (ILF Consulting Engineers in Switzerland, Lombardi SA, B+S AG Bern, Emch+Berger AG Bern) being the “Tunnel project manager”, has been commissioned to carry out all works from the Göschenen portal to the Airolo portal. Within the joint venture, all JV partners are involved in the design work required to deal with the fault zones, with ILF being in charge of the northern fault zone. We wish to thank the construction consortium (lot 241) for carrying out these difficult works under complex conditions.

Look back 1974: ILF’s International Debut in Pipeline Engineering

more

In July 1974, half a century ago, ILF was awarded a contract by Iraq’s State Consulting Company for Oil Projects (SCCOP) to provide engineering and consulting services for the construction of the Strategic Pipeline.

In the same year, Mannesmann contracted ILF to provide design services for the Turkish section of the Iraq–Turkey Pipeline (ITP). Additionally, ILF was tasked with assuming responsibility for the hydraulics of the entire 1,000 km system under a further contract from the Iraq National Oil Company (INOC).

ILF’s success in these contracts not only enabled ILF to enter the Middle Eastern and Turkish markets, but also to apply ILF’s pipeline expertise on an international scale for the first time. In addition, assuming a leading role in the field of Pipeline Engineering, which had previously been dominated by American companies, ILF was also able to establish this field in German-speaking countries.

ILF’s pipeline expertise was developed with determination and purpose during ILF’s early years. Initially focused on oil and gas pipelines, it was rapidly expanded to include pipelines for other media. This expertise was instrumental for ILF being awarded the contract for the Riyadh Water Transmission System (RWTS) in 1977.

Looking back on ILF’s history encourages us to continue acquiring new skills and developing existing ones.

SuedLink: The Next Milestone in Green Electricity Grid Expansion

more

In order for Germany to become climate-neutral by 2045, the country’s electricity grid must be expanded. 
High-capacity direct current lines such as SuedLink will play a key role in ensuring a secure supply of green electricity in the future.

In the SuedLink project, another important milestone has been reached: The application documents for the consultation procedure have been submitted in full and on time, which means that the permit application procedure for design section 2 of SuedLink has been completed and is now pending the final decision from the approval authority. The timely submission of the application documents is important not only because of the challenging topography and technically complex closed crossings along the cable route, but also to ensure that construction can begin on schedule.

The next step will be the start of construction design/detailed design and objection management, which will involve responding to objections from public and private stakeholders. This will be followed by a hearing and, ideally, the planning approval decision in spring 2025, after which construction can begin. SuedLink essentially consists of two direct current (DC) transmission lines (two systems with a voltage level of 525 kV, each with two-pole plastic-insulated cables) running from north to south, which have been planned and are to be built and operated in parallel. 

The two lines will be laid side by side for most of the route to minimize the impact of construction on people and the environment. We are proud of our experts who have been contributing to the SuedLink project since 2019. Most recently, this has involved preparing the full permit application design and application documents. 

We would like to congratulate everyone involved in the project on this milestone and we look forward to the next steps.

Rehabilitation work on the Weissenstein Tunnel has begun (SUI)

more

Major rehabilitation work has begun on the Weissenstein Tunnel in Switzerland. The tunnel is currently closed until the work is completed, scheduled for the end of 2025.
The tunnel was opened to traffic in 1908 and needs to be rehabilitated so that it can continue to be used for decades to come.

The Weissenstein Tunnel is a 3.7 km long, over 100 year old single-track railway tunnel that runs through the approximately 1,300 m high Weissenstein mountain and is owned and operated by the Bernese Alpine Railway Company Bern-Lötschberg-Simplon. The existing tunnel has a masonry vault as well as an open water intake and a drainage system. The large groundwater inflow from the mountain, which can be several 100 l/s, has to be collected and diverted.

The rehabilitation work will include localized partial and complete rehabilitation of the vault in various sections of the tunnel, as well as renewal of the tunnel drainage system, cable systems, safety installations and track. Two existing stations will also be gradually modernized to make them accessible.

IG WST (ILF Consulting Engineers in Switzerland and Emch+Berger AG Bern) has been commissioned by the sole contractor – the joint venture ARGE EWT (PORR Group and fretus ag) – as the “Tunnel and Stations Project Manager”, responsible for all rehabilitation works in the tunnel and the stations.

A step towards decarbonizing Denmark’s heat supply

more

In Aalborg – about a three-hour drive from Esbjerg – the next milestone in Denmark’s sector coupling program will soon be reached; a step towards decarbonizing the heat supply in Denmark. With a total heating capacity of 132 MW, the planned heat pump plant in Aalborg will be two and a half times larger than the world’s largest CO2-based heat pump plant in Esbjerg.

In total, the seawater heat pump plant in Aalborg will supply one third of the city with district heating and save around 160,000 tons of CO2 emissions. The plant, to be built in Denmark’s third largest municipality, will consist of three heat pumps, each with a capacity of 44 MW, and is expected to supply around 550,000 MWh of heat per year. Similar to in Esbjerg, the system in Aalborg will use electricity from renewable energy sources and energy harnessed from seawater to generate heat. Construction of the plant is scheduled to start in August 2024.

We have been suppporting MAN Energy Solutions in the development of and processing of orders for such heat pump plants since 2020, most recently with the heat pump project in Esbjerg.
With the award of the EPC contract for this project in Aalborg to MAN, we are delighted that our team of experts can once again contribute to the planning and implementation of the world’s largest CO2-based heat pump with our electrical engineering, mechanical engineering and automation technology services.

Water Transmission System from Shuqaiq to Jizan (KSA)

more

The Shuqaiq–Jizan Water Transmission System Phase 4 is already having a significant impact in the Jizan region in Southwest Saudi Arabia, even before it becomes operational. This project is set to enhance the water supply infrastructure in the region, addressing a pressing need for a reliable and efficient water transmission system.
The planned Shuqaiq–Jizan Water Transmission System Phase 4 encompasses an extensive area and aims to deliver an astonishing 600,000 m3  of potable water per day from Shuqaiq to the governorates of the Jizan region.
The backbone of the water transmission system is a colossal network of high-quality steel pipelines stretching over 523 km. These pipelines have been carefully designed to withstand the region’s unique environmental conditions and to deliver water efficiently and reliably.
Eleven pumping stations shall be strategically located along the transmission route to ensure that water can be efficiently transported across varying terrains and elevations. Each station will be equipped with state-of-the-art technology to optimize water flow and pressure.
The project includes a network of 77 strategically positioned reservoirs, which shall ensure the consistent availability of water throughout the region. These reservoirs will act as storage and distribution hubs, reducing the risk of water shortages and enhancing overall supply reliability.
18 operational reservoirs will help balance water supply and demand, ensuring a stable and consistent flow of water to consumers.
12 specialized water tanker filling stations shall allow for the efficient refilling of water tankers to supply remote areas in the region. This is especially crucial in areas where direct access to pipelines is limited.
As part of the project’s integration with existing infrastructure, eight tie-in stations will be established to connect to and enhance the functionality of existing reservoirs. This approach not only optimizes resources ,but will also improve the overall water distribution system.
A network of tap-off and cross-over stations shall furthermore ensure that water can be efficiently distributed to various communities, industries and institutions. These stations will facilitate access to water at a local level as well.

The Shuqaiq–Jizan Water Transmission System Phase 4 is a remarkable engineering feat and its realization will be a significant milestone in the development of the Jizan region. With its extensive network of steel pipelines, strategically located pumping stations, and multitude of reservoirs and distribution points, this project is poised to revolutionize the region’s water supply infrastructure, addressing essential water transmission needs for years to come.

400 MW Plant for Green Ammonia Production in Angola

more

Sonangol, Angola’s state-owned energy company, plans to use surplus, low-cost electrical energy from hydroelectric power plants (HPP) in Angola to produce green ammonia. 
In a 400 MW electrolysis and synthesis plant at the Oceânico da Barra do Dande (TOBD) terminal, about 65 km northeast of the Angolan capital Luanda, energy from HPP plants shall be converted into green hydrogen and ammonia before being stored and loaded onto ships for export to Europe. While Africa offers favorable conditions for the production of low-cost, green hydrogen produced in a climate-neutral way, Germany is currently pursuing a strategy to diversify its energy supply.

The 2,000 MW Laúca hydropower plant, located about 200 km southeast of the process plant, shall supply the plant with base-load electricity via the existing power grid. The HPP is currently operating at 1,000 MW rather than at full capacity.

Our team of experts has been commissioned with the pre-FEED (preliminary engineering) for this project. This includes the collection of basic design data, (process and electrical) engineering, preparation of a power grid and power supply concept, cost estimates, environmental and social impact assessments, and risk and safety studies.

KITT (Tunnel safety with AI) research project is completed

more

Upon conclusion of the almost three-year-long KITT (“Artificial Intelligence for Improvement of Safety of Tunnels and Tunnel Control Centers”) research project, we fom ILF are looking back on great challenges and informative discussions. Coordinated by the Federal Highway Research Institute (“Bundesanstalt für Straßenwesen”) in a German-Austrian consortium, options for using Cooperative Intelligent Transport Systems (C-ITS) to improve the safety of tunnels were developed and tested.

Until the recent completion of the project, the results were tested and demonstrated on real tunnel structures together with the project partners and users from the city of Stuttgart as well as ASFINAG. This showed the great potential of the extensive information from C-ITS, which not only significantly improves the safety in tunnels through the use of real-time risk analyses, but also further increases the efficiency and availability of the road network as a whole. A big step towards innovative solutions for mobility in the future!

The research project is being funded by the Security Research Funding Program (“KIRAS”) set up by the Austrian Federal Ministry of Finance (“BMF”) and the German Federal Ministry of Education and Research (“BMBF”) as part of the call for Artificial Intelligence in Civil Security Research (“Künstliche Intelligenz in der zivilen Sicherheitsforschung”).
