While debris reports give locations to the southeast of route, various maps of ocean currents in that area shows the flow to be toward northwest. That would rule out currents
If the debris is in the north equatorial counter current it could drift eastward at up to 3 knots which is like 70nm in 24hours:
Eastward flowing surface speeds in the western section of the current have been estimated by Fratantoni (2001) to be up to 147 cm s-1 and by Richardson and Reverdin (1987) to be up to 143 cm s-1 extending down to 350 m at 28°W
