Geoquip Silvretta

Vessel introduction

Geoquip Silvretta is a state-of-the-art DP2 integrated geotechnical drilling vessel, designed to deliver safe and efficient offshore site investigations in deep and ultra-deep water environments. Permanently mobilised with Geoquip Marine’s GMTR150 heave compensated drilling rig, the vessel provides a stable and highly capable platform for advanced sampling, coring and in situ testing operations.

Designed by Marin Teknik and built at Kleven Verft in Norway, the vessel combines a wide beam hull form with optimised diesel-electric propulsion to maintain precise station keeping while minimising fuel consumption and environmental footprint.

Geoquip Silvretta is equipped with the GMTR150 twin-ram offshore geotechnical drilling rig, capable of handling combined water and borehole depths of up to 2,500 m. The rig incorporates automated pipe and tool handling systems to improve operational safety and efficiency, with all downhole tools fully interchangeable within a single drill string and bottom hole assembly.

A comprehensive range of wireline downhole sampling, coring and in situ testing tools is available, including piston sampling, push sampling, percussion sampling and CPT systems with pore pressure and seismic capability.

The vessel is fitted with a comprehensive 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 and optimisation of drilling and testing programmes as data is acquired.

Recovered samples are handled, logged and stored offshore in a controlled environment prior to transfer to Geoquip Marine’s onshore laboratories for advanced testing where required.

Geoquip Silvretta can deploy Geoquip Marine’s deep-push seabed CPT systems to support in situ testing in deep and ultra-deep water environments. The seabed system uses a straight rod push mechanism to record in situ data to depths of 40 m below seabed, subject to ground conditions.

Accurate station keeping is maintained using a Kongsberg DP system with multiple reference inputs, ensuring precise deployment and repeatable positioning during drilling and seabed testing operations.

    Geoquip Elena Continues Strong Momentum into 2026

    Geoquip Elena has been active in UK waters throughout 2026, with her current project due to complete in early July. As we reach the midpoint of the year, we reflect on a strong 2025 that saw the vessel deliver a diverse range of offshore operations across Europe, from cable lay works in France to a highly efficient North Sea campaign completing approximately 250 CPT locations.

    Northern Breeze crew comes to the rescue during Bowdun operations

    When operations at the Bowdun Offshore Wind Farm called for nearshore survey work, the crew of Njord Survey vessel Northern Breeze answered a different kind of call, pausing operations to assist a nearby vessel in distress and tow it to safety.
