On January 7, 2021, the completely dry mass service provider Ocean Princess struck the uncrewed/out-of-service oil as well as gas manufacturing system SP-83A while running 24 miles southern of Pilottown,Louisiana
Now, some 19 months later on, the National Transportation Safety Board has actually launched an examination record which revealed that inadequate bridge source monitoring as well as a charting mistake brought about the mass service provider striking the oil as well as gas manufacturing system.
The 24-person staff of the Ocean Princess was wandering over night in the Gulf of Mexico prior to mosting likely to New Orleans to fill a freight of grain. The plan of attack to wander throughout the evening with the engine on 15-minute standby, avoiding web traffic as well as systems, NTSB claimed.

“To give the crewmembers rest time after cleaning cargo holds during the day, the master scheduled himself to be on the bridge with the mate on watch, supplementing the watch and the duties of the lookout. After engaging the engine to maneuver the vessel, the master stated he saw a dim yellow light and checked the radar. The master and the second officer on watch investigated the light and believed it was coming from an oil platform 5-6 miles away. Roughly 10 minutes later, the Ocean Princess struck platform SP-83A,” NTSB claimed.
The master as well as 2nd police officer informed NTSB detectives they never ever saw SP-83A on the radar.
Platform on Paper Chart But Not on Electronic One
After the get in touch with, both kept in mind that the system got on the paper graph utilized on the bridge by the friend on guard, however SP-83A did not show up on the digital graph screen as well as info system (ECDIS).
Platform SP-83A was not charted on the main united state digital or paper navigating graphes that supplied the graph information to the ECDIS aboard theOcean Princess The system did show up on the British Admiralty paper graph that the friend on watch was making use of at the time of the get in touch with. The system had actually been contributed to the united state paper graphes when set up in 1990, however, for an unidentified factor was left out two decades later on, in 2010, from 2 larger-scale united state paper graphes. It continued to be off both paper graphes as well as digital navigating graphes (ENCs) for over 11 years– up until after the get in touch with. Following the get in touch with, the National Oceanic as well as Atmospheric Administration (NOAA) upgraded as well as fixed the digital as well as paper graphes that had actually been mistakenly missing out on system SP-83A.
Probable reason for the event
“The NTSB determined the probable cause of the contact of the Ocean Princess with platform SP-83A was poor bridge resource management, which resulted in the bridge team not identifying the platform and recognizing the risk it posed to their safe navigation even though they saw its lights about 10 minutes before the casualty. Contributing was platform SP-83A not being shown on the vessel’s electronic chart display and information system due to a charting error,” NTSB claimed.
“The efficient use all offered sources by a bridge group, consisting of paper graphes, digital graphes, as well as radars, raises cumulative situational recognition as well as adds to a risk-free navigating watch,” the record claimed. “When identifying hazards, bridge teams should avoid overreliance on a single data source by cross-checking information with available bridge resources and communicating identified risks with fellow watchstanders. Technology, such as an ECDIS, can result in operator overreliance and overconfidence that degrades sound navigation practices and negatively affects situational awareness.”
Damage to the vessel as well as system amounted to an approximated $1.5 million.
The Ocean Princess continual damages to the starboard bow, consisting of starboard-side hand rails, the starboard support windlass, as well as the barrier. The ahead pole was torn down. There was likewise damages to portside hand rails. Damage to the vessel was approximated to be over $500,000.
Platform SP-83A endured damages to ladders, pathways, as well as air vent piping on 3 of 4 sides. Damage to the system was approximated to be over $1 million. No air pollution or injuries were reported.
