Shell Oil is in the process of signing a lease with The Port of Seattle to establish what will essentially be a base-of-operations for Shell’s Arctic drilling.
In 2012, Shell used a supposedly indestructible, specially-built tanker, also out of Seattle, which resulted in two groundings and the crew having to be air lifted off. Read the full details on the 2012 incident here.
Also, if you live in the Seattle area, there is a public hearing on the issue. Make your voice heard and get Shell out of Seattle!
