MENCK SHALLOW (ULTRA)DEEP PILE SIZE PROJECTS RESOURCES AFTER SALES ABOUT NEWS You are here: Home Pile Size 150 - 300 kJ MENCK’S MHU 150S AND 300S PILE DRIVING SYSTEMS MENCK Hydraulic Underwater Hammer MHU –S and –T series have played an essential role in the development and progression of offshore oil & gas explorations and developments from the very beginning. MHU’s double acting hydraulic technology combined with the modular yet compact design delivers energy transfer efficiency of up to and above 95%, making the MHU series of hammers the lightest and yet most powerful system for every pile configuration required. OUTER DIAMETER (OD): 0.5 M (24-IN.) - 2.2 M (84-IN.) The MHU 150S and MHU 300S hammers are both directly adaptable to pile sizes ranging from 0.5m OD (24-in.) to 2.2m OD (84-in.). In line with its integral design considerations, these hammers can be utilized for above water and shallow subsea operations in up to 300 m water depth. Once paired with MENCK’s deepwater girdle-type powerpack, the MENCK Hydraulic Deepwater Power Pack (MHP DWS), these hammers can support installation efforts in water depths down to 3,000 m (10,000-ft) effectively and efficiently. Notably, the integral part of the technology – the MHU hammer - is one and the same for every system and size. KEY FEATURES & BENEFITS Suits free-riding or leader-guided operations Meets specification to be operated off drilling vessels through moonpool Fits into tight spaces Plug-and-play setup using quick-connect couplings on hydraulic, hose and umbilical connections Highest net energy vs. system weight ratio in its class making it the lightest system on the market >95% net energy transfer, infinitely adjustable between to the precise energy output required Can be mobilized globally and deployed to 3,000 m water depth Flexible adaptation concept for quick-reconfiguration of system to different pile diameters Single-lift deployment for operations Closed-loop hydraulic system, configurable using biodegradable Oil Numerous safety systems to meet highest HSE standards and improve system lifetime Powered by MENCK's MHP power pack(s) of variable size Controlled through MENCK’s one-fits-all-hammers MHC 21 control unit Supported by MENCK’s MWI combi winch unit for ease of deployment and recovery Run by MENCK’s service technicians OPERATIONAL DATA & STANDARD CONFIGURATION MHU 135T MHU 150S MHU 270T MHU 300S Minimum Nominal Energy Output (10%)[kJ] 15 15 27 27 Nominal Maximum Energy Output | Surface & shallow water [kJ] 150 150 300 300 Nominal Maximum Energy Output | Deepwater @ 1,000 m WD [kJ] 135 135 265 265 Oil Flow Rate @ Max.
