![]() “Since the Hi-Fog system was designed for local protection, the nozzles were positioned below the cable runs and the Hi-Fog system was not effective in suppressing or extinguishing the fire in the cable runs,” the Coast Guard report said. All primary electrical power was lost and none of the main generators could be restarted after that. By the time it was activated, the fire had spread to the cable runs. The amount of fire initially was about two-and-a-half times the size of a “large fabric living-room chair engulfed in flames.”īecause the Hi-Fog local fire-protection system was set on a 40-second delay and the bridge watchstander reset the alarm, the activation was delayed. determined that hot components flew from the cylinders, burning lube oil sprayed out and a pool fire sparked on floor plates. The investigators further wrote that Carnival had been aware that the air cooler system was poorly designed. Referring to the exterior curve of the arch, the evaluators said the “fatigue crack most likely initiated as a result of increased surface stresses at the extrados after the connecting-rod shank was bent,” a condition that “was not present from the beginning of the diesel engine’s service life.”Ĭorrosion and rust were found in heat-exchanger components, and “the poor condition of the air cooler on the B side (of the generator) contributed to the hydrolock event,” the Coast Guard said. “The subject connecting rod failed by progressive fracture in the nature of high-cycle, low-stress fracture,” Carnival-contracted engineering firm Lucius Pitkin Inc. Technicians located the B1 rod and found it bent and broken in two pieces. The piston assembly failed and the adjacent A1 rod was ejected from the crankcase. ![]() The initial trigger in the incident was an undetected hydrolock event and stress on the B1 connecting rod in the No. “This was a critical error which allowed the fire to spread to the overhead cables and eventually caused the loss of power.” “This delay was the result of a bridge watchstander resetting the fire alarm panel on the bridge,” the report said. The engine compartment’s local Hi-Fog system wasn’t activated until 15 minutes after the fire started, the investigators found. In its report issued in July, the Coast Guard highlighted errors in the deployment of firefighting equipment, which was in poor condition to begin with. 5 diesel generator as a result of a thrown rod. ![]() The Panamanian-flagged ship has six main engines, grouped inside two segregated engine rooms that are supposed to prevent a total power loss. 8, 2010, blaze in the two-year-old vessel’s aft engine room led to a blackout. The 952-foot Carnival Splendor was towed to shore after the Nov. cruise ship carrying 4,466 people went dead in the water off Mexico in 2010 because a connecting-rod fracture sparked an engine fire that was allowed to get a stranglehold on the vessel’s wiring due to crew error and firefighting-equipment failure, the U.S. ![]()
