HOUSTON OIL COMPANY WANTS TO BUILD AN ISLAND ON THE ALASKAN COAST Meanwhile, in Prudhoe Bay: Houston-based oil company Hilcorp is seeking permission to construct 23-ac. Liberty Island off the north coast of Alaska by trucking 83,000 cu. yd. of gravel (more than 3 times the volume of the Astrodome) across sea ice to a hole, cut 6 miles offshore above only 19 feet of water. The island would serve as a base for several offshore drilling projects, collectively the first in federal waters off the Alaskan coast. A 5.6-mile undersea pipeline is part of the project. Manmade gravel islands have been in use in the region’s oil fields for decades. [Hilcorp, Associated Press]
