Included potline work with pot tending cranes with metal tapping capabilities, HV and rectifier equipment, one GTC, rodding shop, bath recycling plant, casthouse, alumina storage and transportation systems, one vacuum ship unloader and a 40,000 mt alumina storage silo, compressed air generation and distribution systems, maintenance facilities, warehouses and other general plant infrastructure.
Expanded the potline and increased the metal production from 60,000 tpy to 90,000 tpy. It included additional casthouse equipment, pot re-lining facility and an extension of the alumina pot feeding system, the compressed air system and other infrastructure.
Increased metal production from 90,000 tpy to 180,000 tpy and consisted of a new potline based on the same pot technology, additional pot tending cranes and a new crane maintenance facility, HV equipment and rectifiers, one new GTC, rodding shop refurbishment, a new bath recycling plant, special buildings for cooling of spent anodes, casthouse extension, a 70,000 mt alumina storage silo, extension of alumina transport system, compressed air system and other plant infrastructure.
Phase IV and V
Consisted of further extension of the second potline and additional production capacity of 40,000 tpy each. These phases included further extension of alumina transport systems, one GTC for each phase, additional cooling building for spent anodes and an extension of compressed air system and general plant infrastructure.
HRV Engineering´s involvement in the Norðurál Grundartangi project evolved from being a sub-contractor in phase I to becoming the only EPCM service provider.
