The RD pile wall was built to protect the foundations of new cruise terminal at Tallinn Old City Harbour from soil erosion. Tallinn is a popular destination on the Baltic Sea serving hundreds of thousands of cruise passengers yearly. In a normal year, more than 300 cruise ships anchor at the Port of Tallinn.
SSAB delivered an RD pile wall, with pile size RD220/10, to a retaining wall at the new cruise terminal in the beginning of 2021. The RD pile wall was the first RD pile wall in Estonia. Main contractor of the project was YIT Eesti AS. YIT Eesti chose the RD pile wall solution for project because of demanding conditions. Large piling machines could not reach the area near the water, as the drilled steel piles had to be installed on a very narrow area of land. Soil conditions were also challenging. There are numerous obstacles in the soil, such as tetrapods, reinforced concrete, and old wood, through which the piles had to be drilled.
