We supply a complete geotechnical solution utilising offshore heave compensated drilling, seabed sampling and in situ testing services from the nearshore to in excess of 2500m water depth.

Gardline owns and operates the Ocean Vantage, a drilling vessel complete with a heave-compensated offshore drilling system. Gardline can also offer additional flexibility with a standalone, heave compensated drill rig that can be mobilised onto vessels of opportunity anywhere in the world. All our drill rigs use standard API steel drill pipe or Geobor and have a capability to drill to 500m.

We provide scientific and engineering solutions worldwide with our team of experts.

Wireline tools are available for deployment inside the drill pipe to perform Cone Penetration Tests (CPTU) and to recover undisturbed samples. The drilling system also incorporates a Geobor-S or PQ3 wireline coring facility enabling recovery of quality rock cores. A dedicated offshore geotechnical laboratory is installed onboard for rapid assessment of recovered samples.

Combined with Gardline’s comprehensive range of in situ testing, seabed sampling and laboratory services, Gardline provides a wide range of marine engineering and scientific solutions.
