Nearshore Geotechnics

Horizon performs detailed nearshore geotechnical soil investigations to support the design, engineering and installation of the following structures:

  • Jack-up rigs
  • Jackets and platforms
  • PLEM and SPMs
  • Wind turbines
  • Pipeline and cable routes
  • Trenching and dredging activities
  • Port developments
  • Bridges and causeways
  • LNG terminals

Nearshore geotechnical investigations are performed from our Self Elevating Platforms (SEPs) mobilised with a drilling rig with wire line drilling systems (PQ3 & Geobor S). These can be supplemented with a variety of Horizon’s in-situ sampling and testing equipment such as SPT, vane and pressure meter testing.

The SEPs and drilling units are easily transported by road or sea for rapid mobilisations. The following services are available from Horizon’s nearshore drilling spreads:

  • Undisturbed and disturbed soil sampling
  • Rock coring
  • SPT testing
  • In-situ vane testing
  • Pressure meter testing
  • In-field soil laboratory testing
