Keppel Offshore & Marine (Keppel O&M) said on Monday that it has made full payment of the fines and damages payable worth 343.6 million reais (US$65 million) to Brazil under a leniency agreement that had been set out earlier.
Greenpeace protests who had tried to prevent a Shell oil ship from reaching Alaska could face fines of up to $5,000.
According to reports, the Coast Guard has warned the protestors have 30 days to either pay the fines or contest the civil citations before a hearing officer.
The environmental group has been ramping up its protest against the move in the past couple of months as Shell looks to resume its operations in the Arctic.
