US – Fish causing loss of vessel propulsion off Galveston

Members transiting Galveston Bay and the Houston Ship Channel (HSC) should note that the US Coast Guard has issued a Marine Safety Information Bulletin warning of an increased seasonal threat of small fish called Menhaden becoming caught in sea strainers. The fish are reportedly attracted to the sea chest of transiting ships and causes clogging of sea strainers. This restricts the flow of cooling water and causes engines to overheat, resulting in reduced or loss of propulsion. Further details and practical recommendations can be found in the US Coast Guard’s Bulletin, a copy of which can be accessed by clicking here.
