Weaver's Cove Energy plans to use liquefied natural gas transports that are even smaller than the second set of vessels it specified in recent updates to its proposal to operate an LNG plant on the Taunton River and newer, stronger tug boats to guide them, the company said. According to South Coast Today, more LNG tankers, however, will sail to Fall River under the change because of the lower capacity of the vessels and because tankers once earmarked to go to a proposed Providence terminal denied by federal regulators will instead head to Weaver's Cove. The changes also require more openings of the new Brightman Street Bridge, the company said.
