Geoquip Marine featured their new Twin Ram Drilling Rig (GMTR150). This twin ram drilling rig can be used for drilling, coring, sampling and testing in all soil conditions in water depths of up to 3,500m, including the borehole depth.

Geoquip designed and engineered the rig as the latest addition to a series of modular ram hoist type rigs which can be easily mobilised from vessels of opportunity. GMTR150 enables the company to survey at greater depth than the rigs in the existing fleet and therefore expand into deeper water markets.

“The GMTR150 builds on the success of our GMTR120 rig and is suitable for drilling, coring, sampling and in-situ testing, including PCPT,” explains Andrew Wright, CEO of Geoquip Marine.

“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,” he adds.

GMTR150 has been mobilised on board Poseidon-1, a new build DP2 vessel which has been designed and built in Japan, providing an extremely stable platform for deep water drilling operations. It is particularly suitable for pressure and non-pressure coring of gas hydrates in deeper waters and has already seen its first use, performing deep water gas hydrate exploration in Japanese waters, including CPT, sampling and pressure coring in water depths in excess of 1,000m.

“This is a milestone in offshore geotechnical and geological investigation equipment - in terms of quality, penetration depth and adaptability the spread presents an excellent addition to the current deep water products available within Geoquip,” Andrew Wright concludes.

The Poseidon-1 and GMTR150 are available for gas hydrate campaigns and geotechnical site investigation surveys in the Far East and the rest of the world.
