The Dhon, it has been mentioned previously that a jack-up rig was the preference for this play, simply because it was the cheapest stand alone option and good availablity but having said that I guess that Galp will make an assessment based on their experience and possible rig sharing with others for a semi submersible.

Generally drill ships, drill in water depth of 500m or more and can cost anywhere from 3 to 5 times more cash to contract. Once you go to that water depth its the only option.

I believe there are plenty of jack-ups available at the moment. The only downfall with a jack-up is blowout and collapse but I think that will not be a problem on the seafloor base we are drilling into.
