Geoquip Saentis + GMR600

Vessel introduction

Built in 2005 and converted for offshore geotechnical operations in 2019, Geoquip Saentis is a DP2 multi-purpose support vessel (MPSV) configured to deliver efficient and reliable offshore geotechnical site investigations. The vessel is particularly well suited to projects requiring a combination of borehole drilling and shallow geotechnical operations.

With a fully heave compensated GMR600 drilling rig installed over the midship moonpool and an aft A-frame for shallow geotechnical equipment, Geoquip Saentis provides a stable, flexible platform capable of operating safely across a wide range of environmental conditions.

Geoquip Saentis is equipped with Geoquip Marine’s fully heave compensated GMR600 drilling rig, capable of handling combined water and borehole depths of up to 600 m. The rig incorporates remote tool handling, mechanical pipe handling and an iron roughneck to minimise manual intervention and enhance operational safety.

A comprehensive range of wireline downhole sampling, coring and in situ testing tools is available, including piston sampling, push sampling, wireline core barrels, percussion sampling and PCPT systems. All tools are fully compatible within the 5½” API drill string, enabling efficient operations.

The vessel is fitted with a dedicated offshore soil and rock testing laboratory, enabling Geoquip Marine’s geotechnical engineers to classify samples and determine strength parameters in real time during offshore operations. This supports on-board engineering assessments such as pile capacity and installation analyses as drilling progresses.

Routine sample handling, photography, classification and secure storage are carried out offshore, with recovered samples stored in a temperature-controlled environment prior to transfer to onshore laboratories where required.

Geoquip Saentis can deploy a range of shallow geotechnical and seabed investigation equipment via the vessel’s stern A-frame. In addition, the vessel can be mobilised with Geoquip Marine’s deep-push seabed CPT systems to support in situ testing requirements.

Accurate station keeping is maintained using multiple DP reference systems, including independent DGPS and acoustic positioning, ensuring precise deployment and tracking of subsea equipment throughout operations.
