Den nye bygning omfatter 2.430 m² i stueplan og 275 m² på første sal. Derudover blev den eksisterende fiskeindustribygning ombygget og udvidet med blandt andet to store fryserum og personalefaciliteter. Det nye anlæg rummer to produktionslinjer – én til rødfisk og én til torsk og kuller.
Bygningen indeholder kølerum til både råvarer og færdigvarer. Som en innovativ løsning er der etableret et særskilt kølerum til færdigvarer, hvor temperaturen kan sænkes til -10 °C. Anlægget omfatter desuden modtagehal, teknikrum, fryserum, værksted og øvrige driftsfaciliteter. Produktionslinjerne og procesudstyret er leveret af Marel og Skaginn 3X, mens fryseanlæggene er leveret af Frost, suppleret med udstyr fra en række andre leverandører.
Der er lagt stor vægt på hygiejne i produktionshallen, som rengøres grundigt med vand hver dag. Derfor er vægge og gulve projekteret til at modstå daglig vådrengøring. Ventilation, elinstallationer og vandførende installationer er placeret i et separat loftsrum, så produktionshallen er fri for rør og installationer – bortset fra de nødvendige tilslutninger til produktionsudstyret.
Projektet blev udviklet efter BIM-metoden (Building Information Modeling), hvor alle bygningsdele blev modelleret i 3D. De tværfaglige modeller gav alle projektets parter mulighed for at koordinere og gennemgå projektet digitalt, og virtual reality blev anvendt som en del af projekteringsprocessen.
Arkitekt var Helgi Már Halldórsson fra ASK Arkitekter.
Verkís leverede projektering af bærende konstruktioner, sprinkleranlæg, VVS- og ventilationssystemer, belysning, elinstallationer, brandalarmanlæg, passiv brandsikring, kameraovervågning, telekommunikationssystemer, jordarbejder samt BIM-projektering.
Udfordringen
Reykjavík Energy owns the Hellisheidi geothermal power plant, a combined heat and power plant located about 20 km from Reykjavík in south-west Iceland. The area is one of Iceland’s most active high enthalpy areas. A new area, at Gráuhnúkar, is being investigated for steam and fluid extraction. The purpose of the plants is to meet increased demand for electricity for industrial and domestic use and for hot water for heating. The 303 MWe geothermal power plant in Hellisheiði, Iceland, was commissioned in 5 stages during the years 2006-2011. The first stage was completed in 2006 with two high pressure geothermal turbines of 45 MWe capacity each. The second stage was completed in 2007 with one low pressure geothermal turbine of 33 MWe capacity. The third stage was completed in 2008 with two additional high pressure geothermal turbines, 45 MWe each.
In 2010 a heating plant for hot water generation was added to the plant, intended for district heating. The heat output of the first stage is 133 MWth and two further 133 MWth stages are to follow later. At the same time the Hellisheiði hot water main was put into service. The main is a 19,5 km long pipeline, 0,9-1,0 m in diameter, that carries hot water to Reykjavík. In 2011 the 5th stage of the plant was finished, which includes two new 45 MWe high pressure geothermal turbines, similar to the former turbines, situated in a new power house in Sleggjubeinsdalur.
The plant utilizes 500 kg/s of 180°C geothermal steam for electrical generation. The hot fluid is extracted from 30 wells, 2.000 – 3.000 m deep, and is led through steam and mist separators before entering the turbines. The high pressure steam gathering system operates at 9 bara pressure. The low pressure steam is generated with flashing of brine water from the steam separators at a pressure of 2 bara. The generating units are of single flow, single flash type with axial exhaust. Cooling is achieved through wet cooling towers of the counter flow type.
The main components of the electrical system for each unit consist of a 50 MVA generator, 50 MVA step-up transformer to 220 kV transmission voltage, an 11/11 kV transformer for connection to the 11 kV station service system and two 11/0,4 kV transformers for station service. The generating units, as well as the 11 kV and 0,4 kV distribution boards, are monitored and controlled by the state of the art control- and protection equipment.
