ILF ranked nº 6 among Top International Design Firm for Pipelines


In 2018 the ENR Global Sourcebook published its 77th ranking for top inter­na­tional design firms. Once more, ILF Consulting Engineers was able to secure its position as a top inter­na­tional design firm for pipelines, being ranked 6th and thus improving on its 10th position from the 2016 ranking.

Pipeline projects have played an important role in the ILF Group ever since its founding in 1967. ILF’s first project was the Transalpine Pipeline (TAL), a one-of-a-kind project which, due to its crossing the Alps, was probably the most difficult pipeline project in the world at that time.
For more than 50 years, ILF Consulting Engineers has continued to establish itself as a trusted consultant and global player for the designing and engineering of demanding and challenging major pipeline projects. Having sometimes had to break new ground in order to find the optimum solution, ILF has provided its clients with indivi­dua­lized solutions, from planning to decom­mis­sioning. Whether in extreme mountain terrains, under challenging weather condi­tions, or over long distances, ILF has designed some of the largest pipeline systems in the world.

Amongst many others, ILF was involved in the Abu Dhabi Crude Oil Pipeline Project (ADCOP), the Trans-Adriatic Pipeline Project (TAP), the Trans Anatolian Natural Gas Pipeline Project (TANAP), Trans-Asia Gas Pipeline (TAGP), the Turkme­nistan-Afgha­nistan-Pakistan-India (TAPI) pipeline and the Nigeria-Morocco Gas Pipeline.

World-Scale Gas Separation Unit & Pipeline in Kazakhstan


Germany/Kazakhstan, February 2019 – KLPE, an affiliate of the United Chemical Company (UCC), initiated Kazakhstan’s first world-scale GSU project, which, with its total capacity of 1,250 ktpa, is to supply feedstock to the polyethylene plant in the Atyrau Region. The project is being executed as part of a Joint Develo­pment Agreement between the UCC and Borealis. ILF Consulting Engineers (ILF) is delighted to have been commis­sioned to carry out the Project Management Consul­tancy (PMC) services, including the super­vision of a Detailed Feasi­bility Study (DFS), which will support KLPE in the delivery of this strate­gi­cally important project.

“These strategic UCC initia­tives pave the way for the Republic of Kazakhstan’s estab­lishment as a global player in the polyolefin market. By utilizing advanced techno­logies, engaging world-leading contractors and suppliers, and targeting high levels of safety, relia­bility and opera­bility, we aim to ensure the maximum return on capital invest­ments” says Maksim Sonin, UCC Project Portfolio Managing Director, and Board Member.

“ILF is proud to support KLPE in this profes­sio­nally-led and rapidly-progressing project. With the team’s ability to integrate ILF’s Western style of project management and Kazakh engineering requi­re­ments with local, state-owned project execution processes, as well as the expertise offered by the team, I am highly confident that the DFS phase will create the maximum value for UCC and its partner, whilst supporting their strategy of sustaining Kazakhstan’s develo­pment in the polyolefin market” adds ILF Project Manager and Upstream Area Manager Helge Hoeft.
The heart of the project is the NGL recovery facility, located close to the Tengiz oil field, with a maximum feed gas capacity of over 7 billion Sm3/a for recovering ethane and heavier components as feedstock for the polyethylene project. In addition, a feed gas pipeline from TCO’s facilities, an appro­xi­mately 180 km long C2+ export pipeline to the polyethylene plant, and a redelivery gas pipeline to the GEEP pipeline, are within the project scope.

Creating New Horizons Together


“Contri­buting to improving quality of life around the world” is a motto that not only fits with ILF’s vision, but certainly also applies to the association Engineers without Borders Austria (IOG – Verein Ingenieure ohne Grenzen Austria). For more than a year now, the two insti­tu­tions have been success­fully colla­bo­rating with each other, most notably on the Tyrolean regional group’s “EduZapa” project.

As part of this project, the Tyrolean regional group, which includes some ILF employees, has been improving educa­tional oppor­tu­nities for school pupils in rural Mexico, since 2016. To ensure that the 3rd project imple­men­tation phase was carried out at a high technical level, the planning of the drainage and roof truss was examined by experts from ILF. Several workshops on the topic “Internal Processes” were also held by ILF.

Both ILF and the Tyrolean regional group value the fruitful coope­ration with each other, and look forward to continued colla­bo­ration during the 4th project imple­men­tation phase planned for this year.


ILF rushes into Australia’s hydropower market


At the end of last year, ILF Consulting Engineers was commis­sioned by EnergyAus­tralia as provider for independent verifier services for the pumped hydro project using seawater at Cultana in South Australia.

The facility would be capable of producing 225 megawatts (MW) of electricity with around eight hours of storage. That’s the equivalent of installing 126,000 home battery storage systems, but at a third of the cost. Pumped hydro works by using two bodies or reser­voirs of water, one at a high elevation, at the top of a hill, and another at a lower elevation, at the bottom. The Cultana project will also include two penstocks, a power­house containing two rever­sible Francis turbines, a tailrace structure and a seawater intake/outfall structure as well as a connection to an existing 275 kV trans­mission line and balance of plant systems. The water to fill the reser­voirs will be sourced from the Spencer Gulf. This water will pass through a pre-treatment filter and then be desali­nated via a reverse osmosis process.

It’s poten­tially a great, cost-effective way of integrating renewable power and ensuring energy is reliable and affordable.

First Francis turbine in a crude oil pipeline put into operation


On September 21, 2018 the Transalpine Oil Pipeline (TAL) officially put the world’s first recovery station that uses a Francis turbine into operation.

The Taimeralm energy recovery station is located in the munici­pality of Mittersill (Salzburg) at an altitude of around 1,335 m above the sea. The Transalpine Pipeline carries crude oil from Trieste to Ingol­stadt via the Alps. This innovative and worldwide unique station allows the potential energy in the gradient north of the Felber­tauern tunnel to be used for the first time to recover energy in an environ­mentally friendly manner. The energy is recovered by means of a Francis turbine with a directly coupled synchronous generator. The electricity produced is fed into the grid.

The bottleneck capacity of the Taimeralm energy recovery station amounts to 2,500 kW. An annual power generation of approx. 11.5 GWh is achieved. This corre­sponds to around 12 % of the annual energy demand of TAL Austria or the average annual energy demand of 3,000 house­holds. The diffe­rence in altitude between the high point at Felber­tauern and the station is 237 metres.

ILF Consulting Engineers has been a partner of TAL in this project since 2006 and was respon­sible for the following services: feasi­bility studies (2006 and 2009), conceptual design and site definition, permit appli­cation design, tender design incl. award of contract, site super­vision, support during commis­sioning and management of authority notifications.
