Top Hole Drilling

Top Hole Drilling (Riserless Drilling) is one of the main focus areas for Norshore. By using the Norshore concept to drill the top hole sections and pre-install the wellheads, operators will achieve many advantages:


  • Large cost reductions related to a conventional MODU (semi sub).

  • Increased utilization of conventional MODU’s on contract

  • Advanced (accelerated) development and project time

  • Advanced (accelerated) production

  • This is valid both for exploration wells and for production wells.
