In 1914 was ordered from Werf Conrad,Haarlem
for Russian MPS (communication Minystery)
a dredger WARSZAWA , yard No.481
Very probably that unit was not delivered becouse of war
as it is reported completed in 1926
Unfortunately I was not able to find such vessel in Poland

According to
[www.dredgepoint.org]

Length (OA): 42.5 m
Length (BP): 26 m
Width: 6.39 m
Depth: 1.5 m
Total power: 168 kW
Bucket capacity (standard): 0.25 m³
Dredging depth: 14 m

Perhaps somebody knows her fates.

In Gdynia was employed before the WW2 a dredger VARSOVIE
but I think it was another vessel
