Masterplan en meer<br />

Arent Tissingh is vanaf eind 2007 Teamleider<br />

van de afdeling Engineering. Hij<br />

vertelt over lopende en toekomstige<br />

projecten en de gevolgen tot nu toe van<br />

de kredietcrisis.<br />

Arent: “Het Masterplan dat in 2007 werd<br />

opgesteld, is een uitgebreid plan voor<br />

uitbreiding en modernisering van <strong>Aluchemie</strong>.<br />

Het houdt onder meer in dat er<br />

meer ovens worden gebouwd, meer<br />

rookgasreinigers en een uitbreiding van de<br />

Massafabriek, om maar een paar voorbeelden<br />

te noemen. In <strong>2008</strong> zijn de voorbereidingen<br />

voor twee grote projecten<br />

gestart.<br />

Master plan and more<br />

Arent Tissingh has been Team Leader of the<br />

Engineering department since late 2007. Below,<br />

he talks about current and future projects and<br />

the consequences of the credit crisis so far.<br />

Arent: “The Master Plan that was drawn up in<br />

2007 is an extensive plan for the expansion and<br />

modernisation of <strong>Aluchemie</strong>. Among other things,<br />

it entails the construction of more furnaces,<br />

more fume treatment plants and expansion of<br />

the Paste Plant, to name but a few examples.<br />

Preparations for two major projects commenced<br />

in <strong>2008</strong>.<br />

• Het eerste project, <strong>Aluchemie</strong><br />

550.000 ton, omvat de bouw van een<br />

nieuwe oven ter vervanging van onze<br />

bestaande Oven 5 plus een uitbreiding<br />

van de Massafabriek met een<br />

extra, vierde lijn.<br />

• Het tweede grote project is de bouw<br />

van Rookgasreiniger 7.<br />

Door de kredietcrisis, die eind <strong>2008</strong> begon,<br />

hebben we het project <strong>Aluchemie</strong><br />

550.000 ton uitgesteld voor een nog<br />

nader te bepalen periode en het project<br />

Rookgasreiniger 7 met zes maanden.<br />

Dit laatste overigens met toestemming<br />

van DCMR.<br />

• The first project, ‘<strong>Aluchemie</strong> 550,000 Tons’,<br />

involves the construction of a new furnace to<br />

replace our existing Furnace 5, plus expansion<br />

of the Paste Plant with an additional fourth line.<br />

• The second major project is the construction<br />

of Fume Treatment Plant 7.<br />

Because of the economic crisis, which started<br />

in late <strong>2008</strong>, the <strong>Aluchemie</strong> 550,000 Tons project<br />

has been postponed until further notice, and the<br />

Fume Treatment Plant 7 project by six months.<br />

The latter has the approval of DCMR.<br />

A range of major projects were also carried out<br />

in <strong>2008</strong>, such as the completion of the ‘Revision<br />

and expansion of Furnace 4’ project, and the<br />

new construction of Fume Treatment Plant 6.<br />

22<br />

Verder zijn in <strong>2008</strong> diverse grote projecten<br />

uitgevoerd, zoals de afronding van project<br />

“Revisie en uitbreiding van Oven 4” en de<br />

nieuwbouw van Rookgasreiniger 6.<br />

Hoewel Oven 4 officieel al eind 2007 is<br />

opgestart, was deze oven in februari<br />

<strong>2008</strong> pas op volle snelheid. Deze oven is<br />

nu geschikt gemaakt voor grotere anoden<br />

voor onze klant Norsk Hydro Karmoy.<br />

Tijdens het project is besloten dat Oven 4<br />

met één kraan gaat opereren en dat de<br />

zuidkraan, die in 2007 uit de oven is gehaald<br />

voor aanvang van de revisiewerkzaamheden,<br />

niet meer werd teruggeplaatst.<br />

Although Furnace 4 officially became operational<br />

in late 2007, it was not working at full capacity<br />

until February <strong>2008</strong> and has now been adapted<br />

to be able to make larger anodes for our customer<br />

Norsk Hydro Karmoy. During the project it was<br />

decided that Furnace 4 would continue to operate<br />

with a single crane, and that the southern crane<br />

(which was removed from the furnace in 2007<br />

prior to commencement of revision) would not<br />

be put back. The new crane beams that were<br />

ordered for the southern crane of Furnace 4 as<br />

part of the project will be used to replace the<br />

45-year-old crane beams of the southern crane<br />

in Furnace 2. This means that Furnace 2 will<br />

also be ready for the future. A fact unknown to<br />

many was that the Revision of Furnace 4 project<br />

also involved work in Furnace 2. This was<br />

because one of the project objectives was to<br />

adapt <strong>Aluchemie</strong> to be able to produce the new,<br />

larger Karmoy anodes.<br />

Oven 4 in aanbouw<br />

Per year, around 65,000 tons of these anodes<br />

will be produced in the newly revised Furnace<br />

4, and around 20,000 tons in Furnace 2.<br />

Replacing the beams of the southern crane in<br />

Furnace 2 is scheduled for week 20 in 2009, at<br />

which time Fume Treatment Plant 6 will be<br />

linked to Furnace 2. Only after that will the<br />

Furnace 4 project be officially complete.
