Currently, two production units in Maersk FPSOs operateusing this technique. A third unit is planned to convert tore-injection during 2009.Accidental dischargesAlthough every effort is made to prevent accidental discharges,incidents still happen. A formally approved OilSpill Contingency plan needs to be in place for each offshoreoperation, describing procedures in the event of aspill. Through continuous monitoring, adherence to proceduresand planning, Maersk Drilling and Maersk FPSOsseek to keep unplanned discharges to a minimum – strivingto reach the target of zero spills zero spills.In figure 9 the numbers of spills in 2007 – 2008 is seen.76543210Oil & Fuel spillsDrilling fluid spillsChemical / Other spillsQ32007Q42007Q12008Q22008Q32008Q42008Figure 9: Number of accidental spills to the sea 2007 – 2008distributed among oil & fuel spills, drilling fluid spills andchemical/other spills.Three major accidental spills occurred in late 2008 on twodrilling rigs. These spills account for the major part of thetotal amount of discharges. Out of the total spillage, 86 %consist of seawater spillage from mud pits and thus witha low environmental impact.

This target has not beenreached due to these three major spills.
