Permanent sea wave brake barriers during port reconstruction, Rennesoy Island, Norway 

Situation before renovation

Port Hanasand on island Rennesoy Norway is used as back up for the main ferry port Mortavika near Stavanger. As the port needed to be profoundly rebuilt and capacity increased, stone barriers were used to protect the site from the strong waves in this part of the island, but this was not enough, and an additional quick solution was needed to reinforce the protection – AquaRockBag®. 

Facts

• 200 Bags 2T AquaRockBag® –Classic and Prime – were used
• Installation was done on site within 2 days, instead 10 days using crash stones
• Cost savings in material, excavator renting time and labor force are estimated at 40.000 €
• AquaRockBag® absorb water energy, preserves natural processes and minimizes the impact on the substrate. 
• AquaRockBag® in this case due the high performance will remain as permanent protection.
