This new method of installation, which creates only minimal noise compared to traditional piling, and far less disturbance to coastal communities, sea mammals and fish, is common in the oil and gas industries.
During installation, rather than using piledrivers, the Borger units pump water out of the giant steel upside-down buckets (open on one side that faces downwards), creating a pressure difference vacuum. Helped on their way by the weight of the structures, this anchors them into the seabed before they are then hermetically sealed.
Borger’s pumps, with their high performance and significantly smaller footprint, are already widely utilised in the marine and offshore sectors.
