Update and Final Report
Source report excerpt: “Update and Final Report The field information has changed once again, but the following is based on direct USCG investigation rather than the information that was passed third party to the USCG. First, the product in the tank was, in fact, diesel. The initial trajectory analysis would therefore be valid. Second, there is specific information as to the actual volumes: the capacity of the Number 4 STBD Tank was 46,000 gallons. It received 41,729 gallons for transport offshore. Approximately 40,000 gallons had been transferred when the incident occurred. The separation after the allision was reported to have result in very little loss of product to the Gulf of Mexico. The hole in the vessel’s […]”

Automatically assembled from NOAA's incident record and substantive Public Affairs or Situation Update posts. Dates are NOAA posting dates, which can differ from when events happened or original reports were published. Excerpts retain the source's wording and uncertainty. This account does not independently establish the cause, current outcome or safety of the area. NOAA coverage is selective; missing updates do not mean nothing happened. The map shows one approximate incident area, not a vessel track.
