VESSELS

Helms Geomarine currently operates two geotechnical survey vessels, the Dolphin Geo Survey and the Keyfield Helms. Both vessels are equipped with a heave compensated drilling system.

Dolphin Geo Survey is a 2014 KRS-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.

Keyfield Helms is a 2014 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.

The vessels offers a range of drilling, sampling, coring and insitu testing services via its HG30A and HG30 Drilling Rig respectively and rated to a maximum load of 30 tons fitted with Dando 1000 top drive power swivel.

The system is heave compensated for a stable drilling operation and capable of handling up to 600m of standard 5-inch OD API drill pipes. An AP van den Berg WISON down-hole CPT system is also available to undertake PCPT operation in real-time with a maximum depth capability of 300m below seabed.

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
