In American Samoa, almost 200 litres of diesel fuel was removed yesterday from the long-liner that has run aground on the reef off the airport, the Seahawk 68.
The fuel removal operation had to be cut short because high swells made it unsafe for the clean-up crew to work.
Jeremiah Winston of the Coast Guard Pacific Strike Team from Honolulu says they hope to continue pumping off the fuel remaining 1,300 litres bit by bit throughout this week.
Mr Winston says the vessel is still in one piece though it's rocking back and forth on the reef.
He says they have nearly completed booming to protect the harbour from any contaminants that maybe discharged accidentally.
Mr Winston says it's a fishing vessel so there's fish, equipment and all kinds of stuff still onboard that can be discharged, and the Coast Guard want to try and prevent that from entering the water.
