Semi conversion

The world semi-submersible fleet is ageing and current operation demand are based on equipment and systems that were not available when most semi-submersibles where originally built. Deeper drilling depths and adverse weather conditions also bring new challenges for the operators. Owners must either upgrade their existing units or build new vessels. GVA has vast experience in succesfully converting or upgrading vessels, and we can also carry out FPSO conversions and jack-up conversions.

We offer our customers a flexibility and depth of experience not found anywhere else, including:

  • an in-depth understanding of the demands of a modern offshore unit
  • optimal conversion result as GVA is familiar with most of the semi-submersibles or tanker designs and understand both their potential and limitations
  • a project result that in many cases are almost equal with a new unit at a substantially lower cost.
