Hammer Division

Dosco's hammer division works with Hydrohammer Technology, which has found application on the local market. Mainly in the Oil & Gas industry where pile conductors are installed that are much more efficient compared to drilling, especially on cluster wells.

When large diameter piles have to be installed, powerful and reliable tools are required to deliver the amount of driving energy. IHC Hydrohammer is specialized in piling jobs where large diameter piles have to be driven. Due to the anvil design, sleeves can be adjusted to suit any pile diameter.
Besides the use in the Oil & Gas industry, Hydrohammers are used in a wide range of other onshore applications.

Due to the innovative technology the Hydrohammers has been found highly applicable also on coastal / civil constructions and renewable energies sector for building wind turbines which must withstand adverse weather conditions and often their foundations are placed on unstable ground.

Hydrohammers are for example often used for foundation building activities for container terminals, bridges, viaducts and jetty and mooring posts. Recently, interest has primarily increased with regard to the hammer rock breaker combination for the dredging industry. Due to urbanization there are more buildings, less space and there is more environmental legislation. Larger, higher and unconventional structures require more complex foundations. It is in our Hydrohammer’s nature to test the limits. That is what makes the impossible possible.

IHC Hydrohammer

IHC Hydrohammer’s unique design makes it suitable for all types of piling and foundation works, both leader guided or freehanging. With regards to this, all kinds of profiles can be driven like sheetpiles, H-beams, MV-piles, tubular piles and so called combi piles whereby different steel profiles are connected by slots.

Dosco's Hammer Division owns S70 and S90 IHC Hydro Hammers which are capable of installing casing from 16” to 30” OD down to even 50-60m.

We are not limited to this figures and are able to supply on customer demand onshore/offshore services of pile driving up to 350” OD.
