PROTen hang-off tool (HOT)

Designed for conductor or well support during platform drilling and abandonment operations.


Why our PROTen hang-off tool?

The Aquaterra Energy PROTen Hang-Off Tool (HOT) has been designed to provide support to the conductor for a number of operations which will help you save vital rig time. The tool can be used whilst waiting on cement to cure during platform drilling operations, as well as for general conductor or well support during abandonment operations. Using this tool will support rig-time savings of 24 to 48 hours of drilling unit idle time.

  • Rig-time savings of up to 48 hours
  • Provides increased safety during operations
  • Compact and simple to use
  • Expert engineering

Although our system is primarily designed for platform operations, it can also be utilised on a rig floor during exploration well drilling – creating a safer and more controllable support once the conductor has been run and the cement stringer deployed, as well as for proving conductor cuts.

  • Low profile and lightweight design to allow easy positioning in congested cellar deck areas
  • Integral trolley wheels and multiple lift points for handling
  • Cylinder stroke accommodates space out and the slump of the conductor once the cement has cured, to allow the unit to be removed
  • 250 to 400-tonne axial support (other loads available)
  • Fail-safe cylinder design and locking system
  • Engages directly with the underside of the starter head profile or can be used in conjunction with a SUREGrip Tension Ring around the conductor OD
  • Guards in place to protect against moving parts
  • Can support all conductor ODs and string weights
  • Compact, simple to use with ATEX zone 1 control unit panel
  • Bespoke designs and applications available on request

Supporting industry decarbonisation goals:

By using the PROten Hang-off tool to hold the casing at its final position whilst the cement cures, it enables the drill package to skid over to the next well and continue with drilling operations.

With traditional operations, the casing would have been held in its final position with the correct amount of tension/overpull via holding with the top drive or by being locked into the rotary table. Due to the curing process being anything from 12-24 hours (depending on mix) it can waste a lot of rig utilisation time, especially if attempting multiple wells, as no further work can be performed until this curing process has been met.

Using our previous service report data our PROten Hang-off Tool can save circa one rig day per well. The saving of a day’s operational time, equates to 67.71 tonnes of CO2e (using performance data from a mid-range jack-up).
