RAUMA
Rauma,
Wasa Dredging was awarded this contract as a main contractor in 2016 and the deepening of the southern fairway into Rauma began in the spring of 2016. During the following two years (2016-2017) Wasa would deepen the fairway from 10 meter to 12 meter navigational depth. During the project Wasa deployed its entire fleet to cope with the massive amount of work that had to be done in a short period of time. In the spring 2016 Wasa deployed its biggest dredger “Optimus” along with the combined drilling platform/dredge “Boulder”. Optimus started with undertaking the 108 000 square-meter environmental dredging of polluted masses while Boulder started with the drilling and blasting operations. Later in the project Wasa also mobilized the combined driller/dredger “Hector”. Via a sub-contractor a hopper dredger was mobilized to take out the soft sediments.
All of the material, except the polluted masses, during the project was taken to the reclamation area at “Järviluoto”. The building of this reclamation area was a part of the scope and in total Wasa built almost 2 km of new bunds to hold the dredged material.
This project was up until this time the biggest ever performed by Wasa Dredging. The value of the project ended up to be around 38 million euro.
The numbers:
2200000
Soft soils dredged: 2,2 milj m3
1200000
Hard soils dredged: 1,2 milj m3
