Driven pile installation services

driven pile installation

Since the introduction of the first steam hammer in 1886, we have continued to provide outstanding customer service through high quality and innovative pile driving solutions.

Hydraulic hammers are striking hard, delivering consistent energy for reliable pile driving above and under water.

The centre of the pile driving solution is the MHU Hydraulic Underwater hammer. The hammer’s flexible design allows a customisable solution for clients’ needs. Hammers can be provided in varying energy intervals, from 100 kJ, all the way up to, but not limited to, the largest hammer ever built: the MHU 4400S, offering a whopping 4400 kJ of power.

The MHU is built to withstand the harsh offshore conditions and deliver reliable and consistent performance. The complete service program from Acteon ensures the longevity and efficiency of the pile driving system.

POWER REQUIREMENTS

Whatever your energy requirements, MENCK can supply hammers at various intervals from 100 kj to 4400 kj of power. Every project is different and energy requirements differ based on pile size, environment and water depth.

FINDING THE CORRECT PILE SIZE

To find out about each pile size, select your power requirements from the drop-down menu. Standard pile sleeve data is provided, but please note that our insert system allows for quick and easy pile sleeve adaptation for various pile sizes.

100 kj

Originally built for offshore conductor installation with its light weight and versatility, the MHU 100C is ideal for smaller subsea pile installation and onshore construction. The MHU100C is built to withstand harsh offshore conditions and deliver reliable and consistent performance.

KEY FEATURES & BENEFITS

  • Slender design with simple and uncomplicated operator controls.
  • Compatible with standard MENCK power packs and control systems.
  • Energy levels are seamlessly adjusted from 10% to 100% of nominal energy through the MHC 21 hydraulic control system with hammer performance monitored in real-time.
  • Free riding and submersible up to 300 meters.
  • Quick and easy pile sleeve adaptation for various pile sizes, reducing set-up time thanks to the exchangeable insert system.
  • Suitable for subsea portable templates such as the StabFrame™.
  • Dry glider ram weight system makes the hammer more environmentally friendly and ensures a safe and clean operation.
  • Rubber-based shock-absorbing system protects the hammer from energy rebounds and helps reduce maintenance time and cost.
  • Quick connect release for hydraulic hoses to save time during operation.
  • Suitable for operation on drilling vessels through the moon pool.
  • Various options available to suit the application including vertical hose connection configurations in order to fit into tight spaces.
  • Higher energy output with a lower total hammer weight due to the double-acting hydraulic drive unit which not only pulls the ram weight up but also pushes it back down.
  • Lower ceiling clearance for transport and a smaller footprint on deck with offset lifting supports and eccentric pins.
  • Safety shut-off devices are triggered if the shackle leaves its horizontal resting position, indicating tension on the crane line. Sensors monitor hammer to pile contact, so if there is not proper contact to the pile, the hammer will not operate.
  • Reduced energy loss with the pressure compensation system where the system monitors the water level inside the pile sleeve, preventing water blows and associated energy loss.
  • A closed loop hydraulic system minimises the risk of oil emission and biodegradable oil is used.
