The Coast Guard is establishing two temporary safety zones, a 100-yard radius moving safety zone and a 25-yard radius fixed safety zone, around the M/V PIETERSGRACHT, in the navigable waters of the Houston Ship Channel and its vicinity. The temporary safety zones are necessary to protect persons, property, and the marine environment from potential hazards associated with the transfer of gantry cranes. Persons and vessels are prohibited from entering, transiting through, anchoring in, or remaining within the safety zones unless specifically authorized by the Captain of the Port Sector Houston-Galveston or a designated representative.
