1000, 2000, 3000 meters below the surface. There is no room for failure at extreme depths. Since the introduction of its deepwater system (DWS) in the late 1980’s, MENCK has been pushing the technological limits.

MENCK’s innovative solution to inefficiencies of traditional equipment was to develop a unique power pack (MHP DWS) that sits directly on the hammer; needing only a single umbilical with communications, energy and air leading to the surface.

With over 30 projects under our belt, successful installations on projects such as the Kikeh SPAR, Magnolia TLP and BC-10 conductors have increased our ever increasing track record as a technological leader in deep subsea pile driving.

Over the years the system has developed into a fully integrated and flexible deepwater pile driving system; taking into consideration that each project has its own special requirements and the need for an ever decreasing footprint.

MHU “T” series hammer

The MHU”T“ hammers can be fitted with the MHP DWS deepwater power pack. These Hammers offer a range of energy from 135-750 kJ at 1000m water depth.

MHP DWS

Joining the power pack to the hammer offers easier deep water handling and pile driving.

The unique power pack sits directly on the hammer, eliminating the need for long hydraulic hoses that traditionally link the hammer to the surface. By doing this, full energy is delivered to the hammer with only a single umbilical running to the vessel. 

Umbilical

The connection to the surface, this single cable carries communications between computers, provides electrical power for the electric motors and supplies air to create the air bubble needed between the anvil and pile.

MHC DWS

The deepwater MHC 21 monitoring and control system provides vital information such as hammer status, performance to the operator. Real-time control allows active adjustments during pile driving even at 2000m.
