is configured for efficient well intervention operations. In addition, I will keep a close watch on the economics and business case to ensure that the client is receiving what they require. 2.       What kinds of intervention capabilities will the Helix 534 have once she is operational and what class of vessel will the Helix 534 be once the conversion is completed? When operational the Helix 534 will, at first glance, appear as she always has, however she will be equipped with a full intervention riser system and thus be capable of full through tubing intervention operations. Her status as a Mobile Offshore Drilling Unit (MODU) will be maintained and her top hole drilling capability will remain. 3. When converting a vessel like a drill ship into a well intervention vessel, what are some of the biggest challenges encountered? When operating as a drill ship the vessel is expected to remain on location for long periods and perform the well construction process. As a well intervention vessel, the mobilization, location set up, operations and demobilization process typically lasts for 14 to 21 days. Thus the efficiency of handling well services equipment and the ability to be operationally ready in short period of time are key. The emphasis is on making the vessel more well services friendly in terms of equipment handling and also adding multiple levels of operational activity such as well interface preparation at the same time as well service equipment rig up and testing. 4.       What are the differences
