Geoquip Marine have designed and built the Twin Ram Drilling Rig (GMTR150) which will complement the company's existing fleet and enable expansion into deep water markets. The GMTR150 drilling system is a fully heave compensated (6m stroke) drilling ... Morerig. The GMTR150 incorporates a top drive unit capable of handling 5½" or 6⅝" API drill string.

The GMTR150 is suitable for drilling, coring, sampling and testing in all soil conditions in water depths plus borehole depth of up to 3,500m. The Geoquip Marine designed Bottom Hole Assembly (BHA) allows the downhole tools to be fully interchangeable, even with coring, thus mitigating the requirement to recover the drill string (as with some other offshore drilling systems) to change sampling/testing modes.

Wireline cone penetration testing (CPT), push/piston sampler, PS suspension logger, and other downhole tools can be used without having to retrieve the drill string. This makes the sampling process more efficient. The reaction (weight) for the downhole sampling and testing is provided by the 27-tonne seabed frame. The seabed frame incorporates an electronically-driven subsea hydraulic power pack to operate clamps to grip the drill string during testing/sampling if required.

Geoquip Marine's GMTR geotechnical drilling rigs are a series of modular ram hoist type rigs designed to be easily mobilised onto vessels of opportunity. Sufficient spares are carried onboard to perform general repairs whilst offshore. The rig and component parts are designed for transport in standard open-top shipping containers.

The principle of easy transportation and subsequent mobilisation on board a vessel of opportunity is one of the main design premises of the GMR600. Based on ISO container sized dimensions, each derrick section is an approved shipping container, unique to this series.

The GMR600 is suitable for conducting drilling and sampling in all soil conditions up to 600m (water depth plus borehole depth) using steel API drill pipe. A drop in wireline core barrel is used where variable cemented materials are encountered enabling core samples to be obtained without the need to recover the drill string. All downhole tools are fully interchangeable within the single drill string and bottom hole assembly such that any sampling and testing regime can be accommodated.

The GMR600 rig has a Dando 1000 top drive power swivel capable of handling a maximum 6⅝" API drill string length of 700m. An 8 to 20t seabed frame is used to clamp the drill string to enable downhole sampling and in situ testing to be performed using a suite of downhole tools. The rig can be combined with Geoquip Marine's other equipment, including
Geoquip Marine designed, built and commissioned the Twin Ram Drilling Rig (GMTR120) in 2013, which complements the company’s existing fleet of geotechnical drilling rigs and enabled the expansion into deep water markets.... More

The GMTR120 geotechnical drilling rig is compatible with a wide range of wireline, downhole sampling, testing and logging equipment. This includes piezocone penetration testing (CPTU/PCPT), push/piston and percussion sampling, rotary coring, and P-S suspension logging tools. All can be run interchangeably without recovering the drill string. The GMTR120 is also capable of running Logging While Drilling Bottom Hole Assemblies to provide detailed geophysical, geomechanical, petrophysical and geological borehole data.

The GMTR120 is suitable for drilling, coring, sampling and testing in all soil conditions in water depths plus borehole depth of up to 2,500m with an option to extend to 3,000m.

Geoquip Marine's GMTR series rigs are a series of modular ram hoist type rigs designed to be easily mobilised onto vessels of opportunity. The parts are designed for shipping in standard open top containers.

The rig has an automatic pipe handling system, ram hoist system with twin wire suspension for safe and controlled handling of in-hole tools and 6m passive stroke compensation (improved sample recovery and quality).

The seabed frame can clamp onto the drill string and enable in situ testing with the downhole CPT. Furthermore, the GMTR120 is capable of lowering and hoisting the GMCPT200 seabed CPT system, which enables rapid execution of CPT surveys, especially for offshore wind farm projects.
The drilling rig is capable of conducting drilling, sampling and testing operations from a jack-up barge. A simultaneous drilling and casing system is operated with this rig - this being far more efficient in terms of time and equipment than traditional ... Morerod based drilling systems.

The wireline piston sampler or core barrel, and the casing are advanced together, ensuring a high quality sample recovery and a stable borehole. When full, the piston sampler or core barrel is 'delatched' from the lead length of casing, brought to deck level and the sample extruded horizontally.

Guar gum powder is used to form the flush medium during drilling operations. It is mixed with seawater, and the resulting ‘mud’ or flush is then pumped downhole, providing lubrication during drilling, stabilising the borehole and lifting away the cuttings from the base of the hole.

The nearshore spread can be mobilised with a geotechnical soil testing laboratory, allowing technicians and geotechnical engineers to determine soil classification and strength parameters for use in engineering during fieldwork operations. Testing that can be performed in the field laboratory includes: miniature vane, pocket penetrometer and torvane shear strength testing, bulk and dry densities, and unconsolidated undrained triaxial testing and full geotechnical field descriptions to BS 5930 or ASTM standards.

This drilling spread allows the acquisition of high quality data in real-time, which coupled with on board logging and laboratory testing, allows engineering analyses such as spudcan and pile capacity, to be conducted in the field.

Piezocone Penetration Testing (PCPT/CPTU) using AP van den Berg WISON-APB wireline CPT system can be conducted with this spread. It is a wireline system and can be used interchangeably with the sampling and coring barrel, giving the advantage of a flexible sampling and testing regime. As with the sampling and coring equipment, this wireline testing system ensures maximum efficiency during drilling operations. The 10cm² cone with a 3m stroke is an ideal tool to be used in soft ground, giving high quality data.

Parameters recorded by the cone are displayed in real-time on the acquisition computer, include tip resistance, sleeve resistance and pore water pressure. The stroke length during a test is measured by a calibrated flow cylinder.
