ILF becomes involved in North Caspian Offshore Project

more

As part of a joint ven­ture with two part­ners, ILF was awar­ded a 5‑year frame­work con­tract by the North Caspian Ope­ra­ting Com­pa­ny B.V. (NCOC) for the North Caspian Off­shore Pro­ject – the first major off­shore oil and gas deve­lo­p­ment in Kazakhstan.

The pro­ject com­pri­ses five fiel­ds: Kas­ha­gan, Kalam­kas Sea, Kai­ran, Akto­ty and Kas­ha­gan South West. The giant Kas­ha­gan field is one of the lar­gest oil dis­co­ve­ries of the past four deca­des, con­tai­ning appro­xi­mate­ly 9–13 bil­li­on bar­rels of reco­ver­a­ble oil. The com­bi­ned safe­ty, engi­nee­ring and logisti­cal chal­len­ges in this har­sh off­shore envi­ron­ment make Kas­ha­gan one of the world’s lar­gest and most com­plex indus­tri­al pro­jects cur­r­ent­ly being developed.

The scope of ILF work inclu­des con­cep­tu­al stu­dies, pre-FEED and FEED deve­lo­p­ment and other services.

Expansion of wastewater treatment plant Frankfurt/Main (GER)

more

The Stadt­ent­wäs­se­rung Frank­furt am Main (SEF, https://www.stadtentwaesserung-frankfurt.de/) ent­rus­ted ILF Con­sul­ting Engi­neers tog­e­ther with a Ger­man part­ner to plan, exe­cu­te and imple­ment the expan­si­on of the Nie­der­rad Was­te­wa­ter Tre­at­ment Plant (WWTP).

The Nie­der­rad WWTP is cur­r­ent­ly reaching its maxi­mum design capa­ci­ty of 1.35 mil­li­on PE. The expan­si­on is the­re­fo­re urgent­ly requi­red in order to be pre­pa­red for future deve­lo­p­ments in the con­stant­ly gro­wing Frank­furt area. For this rea­son, the num­ber of secon­da­ry aera­ti­on tanks (with a volu­metric capa­ci­ty of 7,200 m³ each) will be incre­a­sed from 8 to 10, and the num­ber of secon­da­ry sedi­men­ta­ti­on tanks (with a volu­metric capa­ci­ty of 1,875 m³ each) will be incre­a­sed from 32 to 40. The pro­ject com­pri­ses the smooth inte­gra­ti­on of the­se new tanks, as well as the asso­cia­ted mecha­ni­cal, electri­cal and SCADA equip­ment, into the exis­ting plant while main­tai­ning con­ti­nuous plant ope­ra­ti­on and com­pli­an­ce with efflu­ent requirements.

Addi­tio­nal­ly part of the assign­ment are the re-rou­ting of exis­ting pipe­work and the con­struc­tion of an access road.

ILF will be invol­ved in all eight ser­vice pha­ses of this pro­ject, which are in accordance with the Ger­man Offi­cial Sca­le of Fees for Ser­vices by Archi­tects and Engi­neers (HOAI), inclu­ding the buil­ding per­mis­si­on app­li­ca­ti­on as well as con­struc­tion super­vi­si­on and com­mis­sio­ning. The com­ple­ti­on is sche­du­led for Febru­a­ry 2027.

ILF and GEV sign MOU for hydrogen project

more

ILF Con­sul­ting Engi­neers and Glo­bal Ener­gy Ven­tures (GEV) have signed a Memo­ran­dum of Under­stan­ding (MOU) to iden­ti­fy and deve­lop green hydro­gen pro­jects in Euro­pe and Aus­tra­lia that inclu­de a com­pres­sed hydro­gen (C‑H2) genera­ti­on and trans­por­ta­ti­on solu­ti­on, offe­ring a valu­able addi­ti­on of mari­ne trans­por­ta­ti­on to the H2 value chain.

ILF will design the upstream infra­st­ruc­tu­re from the pro­du­cer to the export or loading faci­li­ty and the down­stream infra­st­ruc­tu­re from the import or unloading faci­li­ty to the con­su­mer, while GEV will cover the port-to-port trans­por­ta­ti­on of hydro­gen using com­pres­sed gas­eous hydro­gen ships. For pro­jects that invol­ve impor­ting hydro­gen from regio­nal mar­kets in clo­se pro­xi­mi­ty to Euro­pe, such as the Midd­le East and North Afri­ca regi­on, GEV has iden­ti­fied an oppor­tu­ni­ty to leverage off­shore loading capa­ci­ty and deve­lop a com­pres­sed gas­eous hydro­gen solu­ti­on for the off­shore wind indus­try. Thus, a fleet of ves­sels could pro­vi­de an off­shore loading and trans­port solu­ti­on for are­as whe­re an sub­sea cable or pipe­line on seabed is not suitable.

Jens Kott­sie­per, ILF Busi­ness Deve­lo­p­ment Mana­ger, com­men­ted, „The trans­por­ta­ti­on of lar­ge volu­mes of gas is an issue that ILF has been invol­ved with for over 50 years. We are plea­sed to be able to com­ple­ment our pipe­line exper­ti­se with GEV’s exper­ti­se in the cost-effec­ti­ve trans­port of hydro­gen by ship. Working with GEV will allow us to pro­vi­de our cus­to­mers with even more com­pre­hen­si­ve advice on their trans­por­ta­ti­on issu­es in order to deve­lop a solu­ti­on that meets their spe­ci­fic needs.”

Wit­hin the frame­work of the upgrade to four-track ope­ra­ti­on of the Nort­hern fee­der line to the Bren­ner Base Tun­nel, ILF Con­sul­ting Engi­neers and a part­ner were com­mis­sio­ned by ÖBB INFRA to car­ry out the ten­der and con­struc­tion design as well as the geo­tech­ni­cal engi­nee­ring on site for the pri­ma­ry lining of the approx. 2.5 km long Angath tun­nel. Once com­ple­ted, the Angath tun­nel shall ser­ve as the res­cue tun­nel for the 11.5 km long Anger­berg tunnel.

The Schaftenau–Radfeld sec­tion is part of the nort­hern fee­der line of the Bren­ner Base Tun­nel and the­re­fo­re con­sti­tu­tes an essen­ti­al part of the most important North-South rail­way link in Euro­pe. The Anger­berg tun­nel situa­ted near Wörgl is the key ele­ment of this upgrade.

The ent­i­re design ser­vices shall be car­ri­ed out using the BIM method and shall also inclu­de the opti­on for the ten­der and con­struc­tion design tog­e­ther with the geo­tech­ni­cal engi­nee­ring on site for the 2.9 km long sec­tion of the twin-track Anger­berg tun­nel. A sequen­ti­al exca­va­ti­on method (NATM) is plan­ned for the tun­nel structures.

ILF has alrea­dy been invol­ved in the pre­vious design pha­ses and now con­ti­nues to work on this chal­len­ging pro­ject in the next design phases.

Date and time:
Febru­a­ry 26, 2021
11:00 AM — 12:00 PM (CET) / 10:00 AM — 11:00 AM (GMT)

Green hydro­gen is incre­a­singly seen as an indis­pensable part of the Ener­gy Tran­si­ti­on. Ambi­tious tar­gets for pro­du­cing it have been set for the mid-2020s and 2030.

Many pro­jects and use cases are pro­po­sed, but how is an indus­try that cur­r­ent­ly only ope­ra­tes at the level of tens of MW going to reach GW-sca­le quick­ly – and effi­ci­ent­ly – enough? Will access to cheap ener­gy at the bounda­ries of and/or out­side Euro­pe help to make green hydro­gen com­pe­ti­ti­ve in the mid to long term, even taking the need to trans­port hydro­gen into account?

ILF, Den­tons  and Ope­ris have pro­du­ced a white paper on Sca­ling up Green Hydro­gen in Euro­pe. In it, we look across the hydro­gen value chain and con­si­der both the phy­si­cal and contractual/regulatory infra­st­ruc­tu­re that will be nee­ded to make the visi­on of a hydro­gen eco­no­my a rea­li­ty. We con­si­der how to match sup­ply and demand for hydro­gen; sug­gest pos­si­ble models for finan­cing hydro­gen pro­jects and tra­ding their out­put; and review the role of public finan­cial sup­port and other poli­cy inter­ven­ti­ons. We are opti­mistic about the pro­spects, but also rea­listic about some of the chal­len­ges facing this new industry.

We will be laun­ching the white paper at the online seminar.

After a brief pre­sen­ta­ti­on of our con­clu­si­ons, a panel of indus­try experts who are enga­ged in com­mer­cial hydro­gen pro­jects will deba­te the issu­es and share insights from their own experience.

Spea­kers from ILF, Den­tons and Ope­ris will be joi­ned by:

  • Julia Pres­cot, Chief Stra­te­gy Offi­cer and Co-Foun­der at Meri­diam Infra­st­ruc­tu­re, Mem­ber of the UK Natio­nal Infra­st­ruc­tu­re Commission
  • Roland Schul­ze, Mana­ge­ri­al Advi­ser on Low Car­bon Tech­no­lo­gies, Euro­pean Invest­ment Bank
  • Mari­nus Tabak, Plant Mana­ger, RWE

Plea­se click the „Regis­ter now” but­ton below if you would like to attend the cost-free online semi­nar, or to recei­ve a copy of the white paper when it is released.

We look for­ward to mee­ting you vir­tual­ly and to an inte­res­ting dis­cus­sion. Plea­se do not hesi­ta­te to con­ta­ct ILF if you have any questions.

The Minis­try of Con­struc­tion, Housing Muni­ci­pa­li­ties and Public Works of Iraq has awar­ded ILF Con­sul­ting Engi­neers a con­tract to pro­vi­de con­sul­ting ser­vices for a pro­ject that should make desa­li­na­ted sea­wa­ter avail­ab­le for 13 muni­ci­pa­li­ties in the Al Bas­rah governora­te (Iraq). During the next 30 to 40 years, it is expec­ted that the pro­ject will sup­ply more than seven mil­li­on peop­le with pota­ble water.

The pro­ject com­pri­ses a 1,000,000 m³/d capa­ci­ty desa­li­na­ti­on plant, which will desa­li­na­te sea­wa­ter taken from the Ara­bi­an Gulf in the area of the Al Fao Grand Port Deve­lo­p­ment, and a 240 km long water trans­mis­si­on sys­tem, which will trans­port the pota­ble water to nine off­ta­ke sta­ti­ons, thus con­nec­ting this new sys­tem with the exis­ting water sup­ply sys­tems of 13 muni­ci­pa­li­ties. A cap­ti­ve power plant with a capa­ci­ty of 300 MW will pro­du­ce the requi­red ener­gy to desa­li­na­te and trans­port the water.

ILF’s ser­vices are divi­ded into two pha­ses: Pha­se 1 inclu­des the fea­si­bi­li­ty stu­dy, envi­ron­men­tal scoping, con­cep­tu­al design, pre­pa­ra­ti­on of ten­der docu­ments and sup­port of con­tract nego­tia­ti­ons until award of the imple­men­ta­ti­on con­tract. Pha­se 2 ser­vices com­pri­se site super­vi­si­on and PMC ser­vices, from the start of con­struc­tion to the start of operation.

As part of the ongo­ing Ves­t­fold­ba­nen rail­way upgrade sche­me, sta­te-owned Nor­we­gi­an rail­way infra­st­ruc­tu­re com­pa­ny Bane NOR is buil­ding 10 km of new dou­ble-track rail­way bet­ween Dram­men and Kobbervikdalen.
In 2018, ILF Con­sul­ting Engi­neers was hired by the Nor­we­gi­an con­trac­tor Vei­dek­ke Entre­prenør AS as the desi­gner of the most tech­ni­cal­ly chal­len­ging sec­tion of the pro­ject, a 290 m‑long tun­nel mined in dif­fi­cult geo­lo­gy below the ground­wa­ter table. The exca­va­ti­on com­men­ces in low cohe­si­on gla­cio­flu­vi­al depo­sits and pro­gres­si­ve­ly tran­si­ti­ons into full face rock exca­va­ti­on. Exten­si­ve ground impro­ve­ment works in the form of jet-grou­ting will be exe­cu­t­ed from the sur­face in advan­ce of the tun­nel­ling works.

Nor­way has a long tra­di­ti­on of rock tun­nel­ling, howe­ver lar­ge span soil tun­nels are not com­mon in the coun­try. ILF is able to bring exper­ti­se and suc­cess on simi­lar tun­nel designs to this project.

Initi­al­ly, ILF pre­pa­red the Ten­der Design and sup­por­ted Vei­dek­ke during the Com­pe­ti­ti­ve Dia­lo­gue com­pe­ti­ti­on. After the EPC Con­tract was awar­ded to Vei­dek­ke in Octo­ber 2019, ILF deve­lo­ped the Con­cept Design to later car­ry on with the Detail­ed Design, which is cur­r­ent­ly under­way and inclu­des a BIM model which is then inte­gra­ted into a com­bi­ned model of all the works wit­hin the contract.

Operation & safety eqpt.for Germany’s longest bi-direction tunnel

more

The 3.6 km long Kra­mer Tun­nel will be the lon­gest two-way tun­nel in Ger­ma­ny. It is pri­ma­ri­ly meant to relie­ve through traf­fic in down­town Gar­misch-Par­ten­kir­chen and towards Grainau/Eibsee and the federal bor­der at Grie­sen. In 2020, the Staat­li­che Bau­amt Weil­heim con­trac­ted ILF Con­sul­ting Engi­neers to car­ry out the fol­lowing design pha­ses: 5 to 9 (among others, pre­pa­ra­ti­on of ten­der docu­ments, con­tract awar­ding and site super­vi­si­on) for the instal­la­ti­on of the ope­ra­ti­on and safe­ty equipment.

The Kra­mer tun­nel will pre­do­mi­nant­ly be con­struc­ted as a mined tun­nel. Fur­ther­mo­re, the tun­nel will have two ope­ra­ti­ons buil­dings out­side and a cavern insi­de the tun­nel with a 26 m high exhaust air chim­ney. The tun­nel is plan­ned with cross pas­sa­ges acces­si­ble to pede­stri­ans and vehi­cles as escape rou­tes. More than 1,300 LED lights will ensu­re that necessa­ry ligh­t­ing is pro­vi­ded in the Kra­mer Tun­nel. 16 jet fans (55 kW each), and 2 exhaust air fans (420 kW each) ensu­re that the requi­red ven­ti­la­ti­on con­cept is implemented.

Sin­ce 2017 ILF has been suc­cess­ful­ly invol­ved in the Kra­mer tun­nel pro­ject, car­ry­ing out tun­nel­ling and road design ser­vices, pre­pa­ra­ti­on of ten­der docu­ments and risk ana­ly­sis as well as the first three design pha­ses for the ope­ra­ti­on and safe­ty equipment.

A revolution in reporting

more

On account of the gro­wing com­ple­xi­ty of day-to-day pro­ject work, the deman­ds on repor­ting are incre­a­sing signi­fi­cant­ly. Due to the lack of auto­ma­ted pro­ces­ses, clas­sic repor­ting is pro­ne to errors, only par­ti­al­ly up to date and time con­suming as well.

By imple­men­ting ana­ly­ti­cal soft­ware solu­ti­ons such as MS Power BI, the gre­at poten­ti­al of infor­ma­ti­on manage­ment can also be used for repor­ting. The aim is to visua­li­ze pro­ject-spe­ci­fic data both quan­ti­ta­tively and qua­li­ta­tively, and in a struc­tu­red and descrip­ti­ve man­ner. The­se pro­ject cock­pits are used for qua­li­ty assuran­ce and also for pro­ject coor­di­na­ti­on and control.
For the pro­ject, 2. S‑Bahn-Stamm­stre­cke Mün­chen (2nd Munich S‑Bahn Main Line), the Cli­ent, Deut­sche Bahn, reques­ted qua­li­ty assuran­ce for BIM in the design pha­se for various disci­pli­nes. In the cour­se of the gene­ral BIM coor­di­na­ti­on, ILF Con­sul­ting Engi­neers deve­lo­ped the qua­li­ty assuran­ce pro­cess by means of MS Power BI. In a mul­ti-sta­ge pro­ce­du­re, the qua­li­ty of the indi­vi­du­al tech­ni­cal models was eva­lua­ted and pre­sen­ted in a report. After the client’s appro­val, a uni­form work­flow, an inter­di­sci­pli­na­ry tem­pla­te and a pro­ject-spe­ci­fic user gui­de were developed.

For the pro­ject, this con­sti­tu­tes a new stan­dard of qua­li­ty assuran­ce, which has been imple­men­ted for the first time with such pro­fes­sio­na­lism and which will be a yard­stick for future projects.

The Nort­hern Fee­der Line forms part of the Trans-Euro­pean Scan­di­na­vi­an-Medi­ter­ra­ne­an Cor­ri­dor, which stret­ches from the South of Fin­land to the island of Mal­ta. The cur­rent pro­ject is loca­ted along the Munich–Verona axis and is a com­po­nent of the Nort­hern Fee­der Line to the Bren­ner Base Tunnel.

DB Netz AG has recent­ly com­mis­sio­ned ILF Con­sul­ting Engi­neers, as part of a joint ven­ture, to pro­vi­de design ser­vices for the rou­te selec­tion pro­cess invol­ving public par­ti­ci­pa­ti­on for the plan­ned Grafing–Großkarolinenfeld pro­ject area. The Grafing–Großkarolinenfeld sec­tion will con­sist of a new twin-track high-speed line run­ning from Gra­fing sta­ti­on to an area south of Tun­ten­hau­sen. As part of this joint ven­ture, ILF has also been invol­ved in the Großkarolinenfeld–Schaftenau sec­tion in Aus­tria sin­ce 2016. This sec­tion is loca­ted next to the Grafing–Großkarolinenfeld section.

The elec­tri­fied twin-track high-speed line shall pro­vi­de grea­ter capa­ci­ties for rail traf­fic and con­tri­bu­te to reli­e­ving traf­fic on the exis­ting Munich–Innsbruck rail­way line. Faci­li­ta­ting train speeds of up to 230 km/h, the new line is fur­ther­mo­re advan­ta­ge­ous for pas­sen­gers tra­ve­ling long distan­ces. The Grafing–Großkarolinenfeld sec­tion has a length of approx. 23 km and a maxi­mum lon­gi­tu­di­nal gra­di­ent of 12.5 ‰. The ent­i­re pro­ces­sing of the pro­ject has been done using BIM, star­ting from the ear­ly design stages.

Core ele­ments of the design con­tract inclu­de deve­lo­p­ment of fea­si­ble rou­te alter­na­ti­ves, envi­ron­men­tal inves­ti­ga­ti­ons and inter­di­sci­pli­na­ry rou­te selec­tion, as well as per­for­mance of a com­pre­hen­si­ve base­li­ne sur­vey and a pro­ject area ana­ly­sis. The design works will be accom­pa­nied by exten­si­ve citi­zen participation.

TuRisMo reduces the risk in road tunnels

more

With the imple­men­ta­ti­on of EU Direc­ti­ve 2004/54/EC, tun­nel safe­ty beca­me a cen­tral aspect in the design and ope­ra­ti­on of road tun­nels. By doing so, Aus­tria intro­du­ced a per­for­mance-based approach to tun­nel safe­ty. The Aus­tri­an tun­nel risk ana­ly­sis model (TuRis­Mo) is defi­ned in the Aus­tri­an gui­de­li­ne RVS 09.03.11, which descri­bes one of the first methods for ana­ly­zing and asses­sing road tun­nel safe­ty in a quan­ti­ta­ti­ve manner.

TuRis­Mo com­bi­nes dif­fe­rent metho­di­cal ele­ments for ana­ly­zing a tun­nel sys­tem in its ent­i­re­ty and fol­lows a holistic approach. The use of TuRis­Mo offers the pos­si­bi­li­ty of quan­ti­ta­tively record­ing and asses­sing almost all decisi­ve fac­tors influ­en­cing tun­nel safe­ty. This con­tri­bu­tes to ensu­ring that invest­ments for tun­nel safe­ty are used as cost effi­ci­ent­ly as possible.

Combining infrastructures: H2 pipelines in cable routes

more

For the lar­ge-sca­le dis­tri­bu­ti­on of hydro­gen in Ger­ma­ny, the Fach­ver­band der Netz­be­trei­ber (FNB) – the Ger­man Asso­cia­ti­on of Net­work Ope­ra­tors – pro­po­ses to make modi­fi­ca­ti­ons to the exis­ting natu­ral gas net­work as well as to a num­ber of new con­struc­tion projects.

A com­pa­ri­son of FNB’s pro­po­sed hydro­gen net­work with under­ground cable pro­jects in Ger­ma­ny shows that the rou­tes for the direct cur­rent trans­mis­si­on lines, which are alrea­dy in the plan­ning sta­ge, could be mea­ning­ful­ly used to com­ple­te the plan­ned H2 pipe­line net­work. In addi­ti­on, this could incre­a­se the H2 trans­port capa­ci­ties in a North–South direc­tion to appro­xi­mate­ly 10 GWh/h.

In an initi­al stu­dy con­duc­ted by ILF Con­sul­ting Engi­neers, it beca­me appa­rent that pipe lay­ing is tech­ni­cal­ly fea­si­ble wit­hin a lar­ge part of the rou­te for the power trans­mis­si­on lines, with only a few sec­tions lea­ding to incre­a­sed plan­ning and con­struc­tion cos­ts. For the smal­lest part of the rou­tes, a small-sca­le re-rou­ting of the H2 pipe­line is likely to be advi­s­able for eco­no­mic rea­sons. The next steps shall be the exami­na­ti­on of the gene­ral con­di­ti­ons, espe­cial­ly with regard to the project’s chan­ces of recei­ving aut­ho­ri­ty appro­val and a detail­ed con­si­de­ra­ti­on of the tech­ni­cal feasibility.

Like many urban agglo­me­ra­ti­ons, Colo­gne is also expe­ri­en­cing incre­a­sing num­bers of com­mu­ters. In addi­ti­on, the high­ly fre­quen­ted Colo­gne rail­way loop is a cen­tral con­nec­tion point for regio­nal, natio­nal and inter­na­tio­nal rail traffic.

In order to incre­a­se the capa­ci­ty of the line and the fre­quen­cy of the trains on the line, invest­ments are to be made into the expan­si­on of Colo­gne’s local public trans­port sys­tem. ILF Con­sul­ting Engi­neers has been com­mis­sio­ned with the over­all design for the expan­si­on of the S11/S‑Bahn Main Line, packa­ge 1 “VP1” (Köln-Dell­brück to Ber­gisch Glad­bach) (https://sbahnkoeln.de/).

The scope of ser­vices inclu­des, among other things, the plan­ning and design of the trans­por­ta­ti­on faci­li­ties and engi­nee­ring struc­tures, envi­ron­men­tal plan­ning, sub­soil inves­ti­ga­ti­ons, the necessa­ry noi­se and vibra­ti­on inves­ti­ga­ti­ons, the plan­ning and design of the con­trol and signa­ling tech­no­lo­gy as well as over­head trans­mis­si­on sys­tems, and site super­vi­si­on during the plan­ning and design.

Can you teach an old dog new tricks?

Hydro power is com­mon­ly con­si­de­red as a matu­re tech­no­lo­gy. Does this mean that you can­not teach an old dog new tricks?

The incre­a­se in cal­cu­la­ti­on power allows us employ­ing Com­pu­ta­tio­nal Flu­id Dyna­mics simu­la­ti­ons to tailor stan­dard struc­tures to your needs and to design and test tru­ly inno­va­ti­ve hydrau­lics structures.

See in the below video how we used cut­ting-edge CFD models to re-design the Nam Emoun pro­ject in Lao PDR. The key for the trans­for­ma­ti­on of the pro­ject was the imple­men­ta­ti­on of ful­ly pres­su­ri­zed water­ways. To gua­ran­tee ope­ra­tio­nal fle­xi­bi­li­ty and hydrau­lic sta­bi­li­ty, an inno­va­ti­ve baff­led drops­haft struc­tu­re was deve­lo­ped and tes­ted. Thus, the cost of the pro­ject could be redu­ced by USD20 mil­li­on com­pa­red to the pri­or con­trac­tor offer, the ener­gy out­put was incre­a­sed by almost 10% and the con­struc­tion time was redu­ced by 8 mon­ths. CFD was key to turn a bare­ly fea­si­ble pro­ject into a high-per­for­mance invest­ment. So, Yes, you can teach an old dog new tricks.
