Resource consumptionMaersk Drilling and Maersk FPSOs depend on fossil fuelsfor powering drilling and hydrocarbon production.The gas used for power is produced offshore at the FPSOvessels. The same goes for the drill and fresh water,which is produced using water makers on board. Onshorewater resources will thus not be affected immediately.Principal resources in quantities are given in table 4.Total principal resourceDiesel oil74,010 metric tonnesFuel gas11,3890 metric tonnesOnshore activitiesMaersk Drilling and Maersk FPSOs operate local onshoreadministrations with warehouse facilities in all areas ofoperation. The primary environmental concern is the impactfrom electrical consumption, generated waste productsand water consumption.As some of Maersk Drilling and Maersk FPSOs officepremises are shared with other business entities and/or rented, it has not been possible to obtain valid datafrom all entities. Where data is missing local estimateshave been given to establish overall total consumption.Water *279,509 metric tonnesPrincipal impact in quantities is given in table 5.Table 4: Total principle resources in 2008.* Includes both household fresh water usage and raw water(drill water) for drilling fluid composition (approx. 42 % of totalconsumption).In figure 15 is shown the distribution of recourse usage.metrictonnes80000700006000050000400003000020000Diesel (Drilling)Diesel (Production)Fuel gas (Production)Water consumptionTotal principal onshoreElectrical consumption 3,796,900 kWh *Household waste products 161 metric tonnes **Water consumption 22,500 cubic metres ***Table 5: total principle onshore impact 2008.* Based on measured six offices/warehouses and four localestimates** Based on measured four offices/warehouses and six localestimates*** Based on measured two offices/warehouses and eightlocal estimatesThe electrical consumption roughly equals 875 metrictonnes of CO 2calculated based on local emission factorssupplied from the International Energy Agency (IEA).100000Q32007Q42007Q12008Q22008Q32008Q42008Figure 15: Distribution of resource usage 2007 – 2008.The period shows an increase in diesel and fuel gas consumptionfrom the newly commissioned hydrocarbonproduction units in the fourth quarter of 2008.
