The technology

PURPOSE-BUILT FOR SUBSEA ROCK DRILLING

Norsub has developed a custom-built ROV system for specialized drilling in subsea rock.

The system enables drilling up to 6 metres horizontally into underwater rock formations and up to 6 metres vertically into rock beneath the seabed.

Rather than adapting a conventional ROV to the operation, the platform has been developed around the requirements of demanding subsea drilling.
