Wireline Units can be manufactured in various configurations, therefore there not a standard way to categorize them. For example, Wireline Combi Units can be used as well for Slickline only, it depends on client request.
All our Slickline Units can run drums with 700mm outer diameter and because of this, one can categorize them as Slickline units, while one another can categorize them as Cased Hole Logging Units for up to 1/4″ cable.


Two weeks ago our Wireline team from Celle finished the first GOES Offshore Wireline unit.
The second one was finished this week. Our customer Inwatec Combined B.V. from Netherlands owns both units.

Electro-hydraulic driven Offshore Wireline Split Unit to EXPRO North Sea Limited.
Due to its three lifts modular setup acc. to IMO MSC/Circ.860 and ISO 10855-1, with 2 winch modules and operator + power pack module this Unit can be regarded as an Multi Purpose Offshore Unit that supports Expro’s ongoing deployment of HYDRA well intervention services.
While the single drum module is designed for 5/16” E-Line applications with more than 25,000 ft drum capacities, the dual drum winch is manufactured for Slickline application up to 0.160” wire and E-Line/Braided-line applications up to 7/32” with more than 25,000 ft drum capacities.
The winch drive is realized by a hydraulic high performance closed loop drive system, which is driven by a 75KW electric motor with safety features in an “ATEx” configuration.
