BOP handling systems

J.D. Neuhaus BOP handling systems are known for their reliable, robust and efficient operation on land, jack-up and semi-submersible drilling rigs. They have carrying capacities from 20t up to 200t.

The monorail hoists (EH) in our BOP handling systems feature a compact design with low headroom. They can be used as double lifting gear as in standard BOP handling systems or they can be connected by a coupling rod for use as a four-point BOP handling system. For extremely reduced spaces we recommend our ultra-low monorail hoists of the UH series.

Air and hydraulic-driven cranes and kits

JDN offers air and hydraulic-driven cranes suitable for working in hazardous areas as standard. The programme includes explosion-proof:

  • Overhead travelling cranes
  • Underslung cranes
  • Slewing jib cranes

Subsea hoists

The JDN PROFI Subsea series is available with air or hydraulic drives. As well as a sensitive control system, the PROFI hoists are equipped with an overload protection. PROFI subsea hoists are a versatile and indispensable tool for professional divers and are suitable for horizontal work as well as for oblique pulling.

Cryogenic hoists for BOP handling in arctic areas

The temperature range of standard JDN hoists is -20°C to +70°C. JDN has developed hydraulic hoists for applications at temperatures as low as minus 45°C, such as BOP handling in arctic areas. JDN hydraulic hoists are designed to be operated with low-temperature hydraulic fluids and can be operated efficiently at temperatures from -45°C to +40°C.
