The 35 year history of Wasa Dredging began in the mid 1980’s when current CEO Kristian Backlund started the company. The company has since that time rapidly grown from being a small-scale local dredging contractor to taking on large-scale international dredging projects. Today the family owned company is steadily growing while taking on larger and more complicated maritime projects such as the capital dredging of Kokkola fairway in 2018 or the major dredging works performed in the Mälaren area in 2021.

The organisation today consists of highly skilled professionals with vast experience of the dredging business, this know-how can be found all the way from the top management to the operators handling the equipment.

The equipment is modern, newly build and designed by Wasa Dredging specifically for the type of dredging we perform on a day to day basis.

Below are some of the more important milestones:

In 2009 Wasa Dredging started the design and construction of two brand new pontoons: “Hector” and “Boulder”. Simultaneously two new 940 m³ split-barges were constructed. Both Hector and Boulder are still in service today as combined drilling and dredging pontoons. Hector features a Hitachi EX2500 250 ton Hitachi excavator while Boulder features an EX1200 120 ton excavator. Both units are fitted with drill-towers to be able to handle the blasting of underwater rock. Both units are capable of single-handily taking on jobs that include both dredging and blasting works.

In 2014 Wasa build their biggest dredger yet, “Optimus”. Optimus was fitted with and EX3600 360 ton Hitachi capable of handling buckets up to 22 m³ and going as deep as 29 meters. Optimus was first taken into service during the Pietarsaari project and proved itself to be a massive increase in the capacity of Wasa Dredging equipment.

In 2017 the first self-propelled barges were built. “Sinann” and “Boann” boasted a hopper volume of 1001 m³ and allowed for faster navigation in rougher weather conditions. The pair was taken into service during the expansion of the Kalundborg Port in Denmark where the distance to the dumping area exceeded 17 km.

In 2018 Wasa bought the “Transport 52” from Secora in Norway. The dredger was later named “Harald”. Harald is equipped with an EX2500 Hitachi, same as Hector. Harald started working during the fall of 2018 in Kokkola, Finland. Harald has during the last few years been rebuilt and modernized to meet the Wasa standards.

In 2022 Wasa is constructing a new multi-use support platform “Balder” than can be used for land reclamation work, on-water construction or even blasting and dredging work.

Today the fleet consists of four dredgers, two of them being drilling/backhoe combinations, eight split hopper barges, two of them being self-propelled and a range of auxiliary equipment such as the multi-purpose platform “Kampela”, two barsweeping vessels and five crewtransfer/survey boats. This family of high-end, modern equipment will get it’s newest member “Balder” in 2022.
