Wasa Dredging Ltd, a Finland based marine offshore and inland water construction company, is in full action at the Sommarøya harbor deepening project in Norway.
This demanding project consists of a lot of different stages, including 60 000 m3 of underwater blasting, dredging of 170 000 m3 of blasted bedrock and 160 000 m3 of hard soil dredging. In addition some 6000 m3 of soft soil will be removed by environmental dredging.
A rock bank is being constructed as depo for storing the dredged contaminated masses. As the blasting occurs inside of a small recreational port, with blasting right up to the quay walls and housing nearby, this is a demanding job for the Wasa Dredging blasting experts.
Wasa Dredging has deployed the backhoe dredger/drilling pontoon “Boulder” and two 450 m3 split barges together with land based excavators to undertake the job.
