GEOSEA III: our own means for investigating the seabed

A self-elevating barge operated by GEOSEA itself, with its own crew on board — an own means of putting drilling equipment on the seabed, with no dependence on third-party charter to start the campaign.

Why owning your own means matters

Owning our own fleet and equipment means we don't depend on chartering from third parties to start a marine geotechnical campaign — and that translates directly into schedule: less mobilization time between the decision to hire and the first borehole on the seabed.

The means we put to sea

GEOSEA investigates the marine subsurface — in sheltered seas, open sea, rivers, tailings dams and lakes — with these means:

  • Floating barge

    Floating base for drilling over the seabed. The GEOSEA III, self-elevating and with its own crew on board, is the example shown in this page's photos.

  • Platforms

    Support structure for campaigns that require a fixed base at the investigation site.

  • Drilling bell

    Equipment that supports drilling between the surface and the seabed.

  • Drill ships

    Vessels used for drilling campaigns in open sea.

Where we operate at sea

From sheltered coastal waters to the open sea, from rivers to tailings dams and lakes — the same means also support port terminal expansion and dredging projects.

Crew and safety on the barge

The crew aboard the GEOSEA III works in full PPE — helmet and life vest — alongside the spuds and the winch, on every marine drilling campaign.
