Dredging works on the Elbląg River – Construction of a waterway linking the Vistula Lagoon with the Gdańsk Bay
Województwo / lokalizacja: Warmian-Masurian VoivodeshipZamawiający: Maritime Office in Gdynia
Stage IV of the waterway connecting the Vistula Lagoon with the Gdańsk Bay included dredging two sections of the Elbląg River with a total length of 9.45 km.
The project aimed to deepen and expand the existing fairway to improve navigational accessibility and create a new transport corridor.
Scope of works
The project covered two sections of the river: km 7+450 – km 0+000 (7.45 km) and from point P1 (km 0+000) to point P2 (approx. 2.0 km).
It involved dredging, reconstruction and cleaning of the fairway together with supporting infrastructure for subsequent stages.
- Section 7,450 m long from km 7+450 to km 0+000.
- Section 2,000 m long from point P1 (km 0+000) to point P2 with removal of ferromagnetic obstacles.
- Total fairway length covered by the task: 9,450 m.
Fairway parameters – section km 7+450 to km 0+000
- Design bottom width – 60 m (reduced to 40 m on a 900 m stretch near Nowakowo).
- Two passing places: 248 m × 100 m and 300 m × 120 m.
- Technical depth Ht = 5.00 m.
- Total dredging volume – approx. 1.5 million m³.
Fairway parameters – section point P1 to point P2
- Design bottom width – 20 m.
- Slope inclination – 1:3.
- Technical depth Ht = 5.00 m.
- Dredging volume – approx. 93,064 m³.
Executed works
- Dredging of 580,000 m³ between km 7+450 and km 0+000.
- Dredging of 15,000 m³ between points P1 and P2.
- Inspection and removal of ferromagnetic obstacles from the riverbed.
- Transport of spoil to the reclamation field located on the artificial island in the Vistula Lagoon.
