Zone Power - Skid Mounted Logging Unit
The Skid is an offshore skid mounted logging unit that can be secured to a trailer for land
operations. It is for the conveyance of wireline tools in and out of the well. It is transportable,
rugged and self contained. The skid consists of these major components. A drum for spooling
the wire, a hydraulic system to power the drum, a power source or prime mover to drive the
hydraulics and an enclosed operator’s cab which houses the controls and the computer
system for recording.

3. Features
Zone Power’s skid mounted logging
units are built to customer
specifications. The function normally
found on a land based logging truck
are replicated in this offshore skid
unit. These units are self contained
except for electric power which is
supplied by the rig. They can be
stored, transported and operated as a
single self-contained unit.
The skids are very ruggedly built and
are DNV 2-7.1 certified. Great
attention to build detail is evident.
Due to the harshness of the marine
operating environment, all exposed
surfaces use either stainless steel
hardware or have multiple coats of
high quality paint over hot zinc spray.
The diesel prime mover provides
power to the hydraulic controls.
Because the winch is hydraulically
controlled, it can be operated at a
slow constant speed when necessary.
The diesel power pack is also housed
within the self-contained skid unit.
The operator cab provides winch
controls, measurement equipment
and ample space for rack mounted
logging computers. It is climate
controlled and provides safety
features such a steel mesh protective
barrier between the cab and the
winch.

The skid can be lifted as a single unit or if
necessary separated into 2 pieces, the unit and the
drum, to accommodate lifting limitations on smaller
rigs.
