Geoquip Marine’s new twin ram drilling rig claims to have improved drilling, coring, sampling and testing in all soil conditions in water depths of up to 3,500m.
The new GMTR150 is the latest addition to Geoquip’s series of modular ram hoist type rigs which can be mobilised from a vessel.

“The GMTR150 builds on the success of our GMTR120 rig and is suitable for drilling, coring, sampling and in-situ testing, including PCPT,” explained Geoquip CEO Andrew Wright.
“The rig has an automated pipe handling system, a ram hoist system with twin wire suspension for safe and controlled handling of in-hole tools and a six -metre passive stroke compensation. It is also designed to be capable of lowering and hoisting our GMCPT201 deep water seabed CPT unit.”
The first of the GMTR150 rigs is currently operating offshore of Japan where is it undertaking CPTs, sampling and pressure coring in water depths in excess of 1,000m.
Wright believes that the new rig is a milestone in offshore geotechnical and geological investigation equipment in terms of quality, penetration depth and adaptability.
