Helms Geomarine currently carries out drilling services from three geotechnical survey spreads, Keyfield Helms 1, Azuma and G-Star.

Keyfield Helms 1 is a 2017 BV-classed dedicated geotechnical survey vessel equipped with DP2 positioning system that is capable to work in up to 500 meters of water depth. This vessel is also equipped with a large centered moonpool to support stable and safe geotechnical drilling operations as well as a 10-ton A-frame for deployment of seabed sampling and seabed CPT equipment.

Azuma is a 2012 LR-classed dedicated geotechnical survey vessel equipped with DP2 positioning system that is capable to work in up to 400 meters of water and soil depths This vessel is also equipped with a centered moonpool to support stable and safe geotechnical drilling operations as well as a 30-ton crane for deployment of seabed sampling and seabed CPT equipment.

G-Star is a 2023 KR-classed dedicated geotechnical survey barge equipped with 4-point mooring and spud legs system that is capable to work in water depths ranging from 3 meters to 70 meters. This barge is also equipped with a centered moonpool to support stable and safe geotechnical drilling operations as well as a 20-ton A-frame for deployment of seabed sampling and seabed CPT equipment.

The three geotechnical survey spreads offer a range of drilling, sampling, coring and insitu testing services via its HG30, HG30A and GV20 Drilling Rig respectively and rated to a maximum load of 30 tons fitted with Dando 1000 power swivel. An AP van den Berg WISON down-hole CPT system is also available to undertake PCPT operation in real-time.

The geotechnical vessels are the perfect solution to undertake geotechnical survey drilling operation in support of the following activities:

  • Geotechnical investigation for windfarm foundation design and analysis
  • Geotechnical survey for offshore hydrocarbon exploration and development
  • Geohazard survey for exploration Jackups emplacement
  • Shallow gas investigation including very deep pilot holes
  • Submarine cable and pipeline route survey
  • Marine geological research studies
