Skid Unit

The Skid unit is a service unit which consists of a cabin designed and manufactured as specified by the customer. Used as a platform for geophysical measurements in the exploration and production of oil and gas, the container can be operated fully selfcontained and remote from any supplying facilities. Air conditioning and heating systems allow operation in diverse environments. The Skid unit has been designed to withstand temperatures ranging from -40°C – +50°C. Divided into three compartments, the container contains a winch skid, a lab designed to house the control panel for the winch and enough space for any required acquisition and interpretation equipment and the power Skid. Many modern conveniences can be incorporated for the service crew.

Built as conventional and offshore skid unit

  • For transportation by helicop-ter
  • As a see container with a turning facility
  • Skid units for arctic, desert or offshore operations available

Technical features

  • Long life hydraulic compo-nents up to 400 bar
  • Planetary gear built in the drum (no chain necessary)
  • Disk brake built in the plane-tary gear (no external band – brakes)
  • 3 step cable cleaner (me-chanical, pressure air, steam)
  • Depth correction by magnetic marks
  • Single, double or split drum available
  • Maintenance free mercury collector up to 7 conductors
  • Cable spooler with measuring head incl. depth encoder, ten-sion sensor, magnetic mark system

Designed for use in most environ-ments

  • Fully insulated for arctic and desert operations
  • Special under floor heating for the lab
  • Integrated CFC-free air condi-tion
  • Special coated and shielded roof to prevent cabin from heating-up

Technical Specification of the Skid Unit

Self-contained for remote operations

  • Hydraulic winch powered by electrical or diesel power unit
  • Diesel generator for power supply
  • Compartments provided for necessary logging tools
  • Kitchen unit with fresh water tank
  • Sleepers provided

Safety and maintenance

  •  Direct-driven winch without sprocket, chain or other moving parts
  • Hydraulic driven brakes, in case of leakage or failures in the hydraulic system the brakes work automatically by falling pressure
  • Cable spooler for regulated coiling of the cable
  • Oiler system for the cable
  • Drip pan assembled under the winch
  • Mechanically secured transport device for the logging tools
  • Black box which records each second or minute the cable speed, tension, depth, date and time

Depth computer

  • Display of depth in meter or feet
  • Display of tension in kN or lbf
  • Display speed in m/h or fpm
  • Automatic winch drive with preset speed (constant speed independent full or empty drum)
  • Automatic shutdown exceeding max. tension
  • Automatic shutdown exceeding min./max. depth
  • Automatic shutdown at relief of cable to avoid loops
  • Integrated function for calibration of depth and tension
