Abstract
Mobile Offshore Drilling Units (MODUs) are more susceptible to meteorological conditions such as winds, currents and, most importantly, waves. These meteorological conditions generate a movement of the installation that will inevitably be transferred to some extent to the drilling pipe. A mobile offshore drilling unit can include a rooster box configured to move the rooster box along the height of a derrick to which it is attached. An injector configured to attach to an intervention frame of the rooster box, wherein the injector is configured to be releasably coupled to a conduit The injector configured to be positioned on-axis with the conduit in a first configuration and off-axis with the conduit in a second configuration.
