Refurbishment of Geothermal Well

Veitur are currently refurbishing one of the oldest geothermal wells in Reykjavík, at Bolholt behind the Icelandic Stock Exchange. The project is to install a new pump system as well as refurbishment of the well itself. After serving Reykjavík's district heating for almost 60 years there is noticeable scaling in the hole that has reduced its output. It is necessary to re-enter the hole for cleaning and re-casing.

As well as re-entering the hole it is time to replace the old pumping system with a new submersible pump system that that is more energy efficient and make the control more agile with real time monitoring of the holes KPI’s.

Mannvit is responsible for the design of electrical system for the new pump system. Design of Control system and remote monitoring system for the new pump system and review of current buildings and updating design documents to new codes. Mannvit is also doing the commissioning of the control system as well as structural engineering of modifications.
