Drøbak Swimming facility is a progressive and modern swimming hall containing a 25 m, 8 lane competition pool with a great flexibility for a broad group of users and three diving platforms.(1 m, 3m og 5m)
Besides the competition pool it has hydrotherapy pool, children’s pool, Jacuzzi, water slide and wave pool. There is a common entrance for the swimming pool and the gym, along with cofeteria/ dining area, shops and changing rooms. On the second floor is 1,000 m² for rent. Technical room will be in the basement.
Verkís scope of work is a project coordination for collaborative design, structural design, sewage and sanitation system design, pool system design, ventilation systems, electrical and small-voltage systems, lighting design, operating systems, fire protection design, acoustics design, geotechnical engineering and tender documents for contracting. The project is being conducted in collaboration with White Architects, which is responsible for architectural design and project management.
Verkís was responsible for project management, cost estimates, all engineering design, transportation systems, geotechnical engineering, management of building permit licensing, preparation of tender documents, construction time consultation, and preparation of the operating manual. The project is based on BIM methodology.
The Challenge
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.
