Definitions

  • the present invention refers to a seabed drill system, for geotechnical site investigation for the installation of an offshore wind park.
  • the towers, cables and other structures that constitute an Offshore Wind (OW) park are supported on the seafloor.
  • the characteristics of the soils and rocks present at any site are crucial for the OW park design: insufficient site knowledge may seriously jeopardize installation and/or operation. Developers have stopped projects at a very advanced stage quoting poor geotechnical conditions.
  • Geotechnical Site Investigation for OW today implies taking soil and rock samples from scarce and expensive jack-up platforms and/or specialist geotechnical drilling vessels in a process that is slow and very sensitive to weather conditions. Geotechnical site investigation is thus a bottleneck for OW park developers.
  • Remotely operated submarine sampling systems make site investigation more resilient to bad weather conditions and use smaller, easily available supply vessels. They can thus offer a substantial reduction in development cost and extend the time window for GSI.
  • the objective of the present invention is to provide a seabed drill system designed with a modular approach that enables to use smaller and lighter configurations in circumstances when all the depth drilling capability is not required.
  • the seabed drill system comprises a drilling mast module for placing drill rods, said drill rods drilling the seabed, and it is characterized in that it also comprises:
  • a core barrel rack module comprising a frame for placing core barrels
  • a drill rack module comprising a frame for placing the drill rods
  • a remotely operated arm module provided with an arm for collecting and moving said drill rods and/or and core barrels from the rack modules to the drilling mast, or vice versa.
  • the seabed drill system according to the invention can also comprise a base comprising a plurality of adjustable feet and an acoustic sample checker module that detects the presence of a sample inside a core barrel.
  • the seabed drill system according to the invention can also comprise two gantry automated arm modules, one for the core barrel rack module and one for the drill rack module, which also collect and move the core barrels and the drill rods, respectively.
  • the acoustic sample checker module comprises an acoustic probe, such as a short range acoustic phased-array probe.
  • each gantry automated arm module comprises a grabber for grabbing one drill rod or one core barrel.
  • the base can comprise four feet which are independently adjustable in height.
  • the arm of the remotely operated arm module comprises a grabber at one of its ends, said grabber being rotatable, and the arm of the remotely operated arm module is preferably mounted on a position table, which is rotatable.
  • the frame of the core barrel rack module and/or the frame of the drill rod rack module comprise security locks for fixing the core barrels and/or the drill rods in their position in the frame.
  • the drill system according to the invention responds to a modular concept, which enables different borehole diameter options and multiple combinations of push- sampler tools in situ (CPT) test in the same deployment.
  • the main features of the drill system according to the invention are:
