A protester perched herself on a 15-foot tripod in a bid to block the entrance of a Shell fuel transfer station earlier this week in protest to the oil major’s planned Arctic drilling.
The protest was staged on Seattle’s Harbor Island after the US Department of the Interior gave conditional approval to Shell for it to explore for oil in the Chukchi Sea off Alaska.
The company has not drilled in the region since a mishap in 2012.
Environmental activists are preparing for three days of demonstrations starting on May 16 against the plans by Shell to store two drilling rigs in Seattle.
Protesters are planning to meet one of the drilling rigs in Kayaks as it arrives into the port.
The Port of Seattle commission voted on Tuesday to appeal the city’s interpretation of the permit requirements.
It urged Shell to delay the arrival of its rigs for the duration of the legal dispute.
The Arctic is estimated to contain about 20% of the world’s undiscovered oil and natural gas, with some 34 billion barrels of oil in US waters alone.
