KAPOLEI, OAHU (HawaiiNewsNow) - Response crews continued cleaning up an oil spill Monday night off Barbers Point.
An aerial assessment on Monday afternoon found that the oily sheen -- covering about 1.2 square miles-- is located about seven miles offshore, according to Hawaii Independent Energy. The sheen is described as being gray in color, with 10 percent being rainbow sheen, 30 percent silver sheen and the remaining 60 percent being clear water.
A second aerial assessment is scheduled Tuesday to track the spill.
On Sunday, a mixture of water and ship fuel was released from the hose at Hawaii Independent Energy's single-point mooring off Barbers Point during a maintenance operation. The current tides are pushing the sheen towards the south.
The cause of the release is not known, but Hawaii Independent Energy said it will conduct a thorough investigation with assistance from the U.S. Coast Guard. Response efforts are being led by Hawaii Independent Energy, the Coast Guard and the state Department of Health.
Based on the capacity of the hose, less than 1,200 gallons of water commingled with significantly smaller amounts of ship fuel could possibly be released.
Five vessels are at the location of the spill, sweeping the area and using sausage-shaped absorbent materials to pick up the oil from the ocean's surface.
