After more than two days of silence, an oil tanker at the center of a legal dispute over its cargo signaled this morning that it still is anchored 60 miles off Galveston. A maritime tracking system had not detected the tanker United Kalavryta since Monday night when a court ruling made it likely the legal battle will continue.
Thanks so much for that update.
Is it waiting to go to Galveston or Freeport do you suppose?
