Overview
The POSEIDON-1 is a new build DP2 vessel designed and built in Japan. Recently, the GMTR150 geotechnical drilling rig was mobilised on board to perform drilling including CPT, sampling and pressure coring in water depths in excess of 1,000m. The POSEIDON-1 has a very powerful dynamic positioning system which enables the vessel to be suitable for varied offshore works in challenging marine environments.

POSEIDON-1 is fitted with two NIIGATA Z-Peller (CPP) to generate powerful thrust and excellent efficiency. This enables the vessel to be suitable for varied offshore development works which require DPS (dynamic positioning system).

DUAL DP System Installed: K-Pos DP-21+C JOY by KONGSBERG (Autoposition, Auto Track, Follow Target, Joystick System). Reference System (DGPS, HiPAP501).

Equipment & Assets
Drilling & Sampling
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 rig. The GMTR150 incorporates a top drive unit capable of handling 5½" or 6⅝" API drill string.... More

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.
Cone Penetration Testing
Geoquip Marine have developed a 200kN Seabed Cone Penetration Testing System (GMC201) capable of operating in water depths up to 800m (which can be extended to 2,000m on demand), providing a push capacity of 200kN (20t). This enables the recovery of in situ soil engineering data to a depth of 40m or more below the seabed (depending on soil conditions).... More

The GMC201 Seabed CPT unit has two electrical motors which power the chain drive system (CDS) and the piezoelectric cone (PCPT) into the soil.

Key Features

200kN (20t) thrust capacity

Depth rating to 800m (2,000m optional)

Electrically-driven chain drive system (CDS)

Penetration to +40m below seabed (depending on soil conditions)

The GMC200 unit has a subsea hydraulic power unit (HPU) which is mounted on the subsea frame and provides power to the chain drive system (CDS) to push/pull the CPT string and clamping force onto the CPT string by means of hydraulic cylinders.

Sensors & Instruments
Geoquip Marine operates a Robertson Geo PS Logger Probe – a low-frequency acoustic sonde designed to measure compressional (P) and shear-wave (S) velocities in soils and soft rock formations. It operates using indirect excitation rather than mode conversion as in a conventional sonic. It is capable of acquiring high resolution P and S wave data in ... Moreborehole depths of up to 600m in water.

The PS Logger probe contains a unique design of powerful hammer source and two receivers, separated by acoustic damping tubes. To acquire data, the probe is stopped at the required depth and the source is fired under surface command. Firing causes a solenoid-operated shuttle aligned across the borehole axis to strike plates on opposite sides of the probe in turn, setting up a pressure doublet in the surrounding fluid. The resultant fluid motion produces a tube wave at the borehole wall with velocity close to the shear velocity of the formation together with a compressional wave.

As the waves propagate parallel to the borehole axis, they set up corresponding fluid movements that are detected by the two neutral buoyancy 3D hydrophone receivers and geophones, allowing the wave velocity to be determined. The facility to stack multiple shots and filter the data as in normal seismic data acquisition is included in the operating software.
