Twin Ram Offshore
Geotechnical Drilling Rig GMTR150

Geoquip Marine's GMTR150 Twin Ram Offshore Drilling Rig on Vessel
Water + borehole depth
Heave compensation

Ultra-deep water geotechnical drilling capabilities

The GMTR150 can be configured to reach combined water and borehole drilling depths down to 3500m. This Geoquip Marine designed and built twin ram rig is suitable for drilling, coring, sampling and testing in all soil conditions in ultra-deep waters.

Drill rigs for deep water

Reliable samples from challenging environments

The rig is operated to achieve better sample recovery and quality with safe and controlled handling of downhole tools using the rig’s ram hoist system with twin wire suspension, combined with the GMTR150‘s nitrogen charged 6m passive heave compensation capability.

Drill rigs for deep water

Safe and efficient site investigations

Safety is improved with the rig’s mechanized pipe handling system that is remotely operated, allowing for minimum manual intervention.

With the Geoquip Marine designed Bottom Hole Assembly, downhole tools are fully interchangeable without the need to recover the drill string, allowing investigations to run more efficiently.  The GMTR150 is compatible with a wide range of wireline, downhole sampling, testing and logging equipment including:

  • Piezocone Penetration Testing (PCPT) systems.
  • Push / piston and percussive sampling tools.
  • Rotary coring tools.
  • P-S Logging tools.

CPT surveys can be rapidly executed with the Geoquip Marine designed and built GMC201 seabed CPT test system which can be lowered and hoisted by the GMTR150 rig.
