A contract worker was injured by an electric shock on Sunday while working on a coking unit at Marathon Petroleum Corp’s Galveston Bay refinery in Texas City, Texas, a Marathon spokesman said. The refinery’s emergency personnel were able to restore the man’s breathing and heartbeat and he was taken to an area hospital, sources familiar with the incident said. Marathon shut the coking complex and two hydrotreating units in July at the 459,000 barrel per day (bpd) Galveston Bay Refinery for planned work which is expected to continue through the middle of August.
