The Republic of the Marshall Islands (RMI) Maritime Administrator (the “Administrator”) has issued the following attached Marine Safety Advisory (MSA) which relays the Marine Safety Alert 17-16 from USCG. 

Several vessels have reported failures in the cooling jackets of MAN B&W MC-C engines, on which cracks have occurred around the bolt holes of the cooling jackets.

These failures have triggered the following sequence of events: 

  • A loss of the engine cooling water 
  • Overheating of the cylinder cover 
  • An automatic slow-down of the engine 
  • An unintended loss or reduction in the vessel’s propulsion and maneuverability 

As a result, vessels have been grounded or have had collisions while at sea or maneuvering.
