Wasa Dredging Makes Progress on Klintehamn Harbor Scheme

The Klintehamn Harbor dredging scheme, being conducted by Wasa Dredging, is progressing according to schedule.

“We are dredging about 250.000 m³ of material from the harbor and fairway of Klintehamn Harbor on Gotland and about 120.000 m³ of this material is limestone which could be very hard to dredge. The rest of the masses are clay/sand/silt and is very soft,” Mr. Daniel Backlund of Wasa Dredging revealed exclusively for Dredging Today.

The dredged limestone will be used for creation of the new harbor area.

“Wasa is in charge of the filling and we are not using sub-contractors for this. Our company recently purchased a brand new Hitachi EX1200 machine for the job. This is the first land-excavator that we have,” added Mr. Backlund.

“Wasa is expecting to be able to take out all of the hard masses without the blasting. For the job we have deployed “Optimus” along with barges “Miika II” and “Dana II”.

The Finnish dredging contractor is going to take out as much as possible of these hard masses with the 12 m³ hard material bucket, and the rest will be loosened with an “Excentric Ripper” hydraulic hammer.

This major cleanup and construction project is co-driven by Swedish maritime administration (Sjöfartsverket) and Klintehamn harbor.

There are three different dredging areas; the fairway (depth -7,3 m), the turning zone (depth -6,8 m) and the outer harbor area (depth -6,0 m).

The Wasa Dredging’s part of the contract is worth around $8 million (about 68 million SEK).

“The project will be finished at the latest in February 2017, but it is of course in Wasa’s interest to get the project completed as soon as possible to free up Optimus for other tasks,” concluded Mr. Backlund.
