[image] “The Clock Is Ticking”: Inside the Worst U.S. Maritime Disaster in Decades In 1992, EL FARO underwent a conversion at the Atlantic Marine Shipyard in Mobile, Alabama. This conversion included the addition of a 90-foot mid-body section between frames 134 and 135 that added a cargo hold (…

From the same hearing as before. Dr. Stettler: - Can you offer any insight as to why a container Con-Ro container roll-on, roll-off vessel such as El Faro, why that container load might pass the severe wind and roll criteria such as this but would not pass a general righting arm criteria? Jaideep…

I think, transforming an existing RoRo into a RoCon/ConRo is an operation against common sense. Stowing the densely packed containers on top of the loosely packed vehicles and trailers is a port handling necessity, but also a stability nightmare. Packing a lot of iron ore in the double bottom and …

From NTSB p 196 The vessel was not required to comply with SOLAS requirements before or after it was lengthened in 1993 because it was in domestic service. The ship’s 2010 entry into the Coast Guard ACP, which was retroactive to 2006, subjected it to the equivalency requirements that are develope…

Something is wrong with USCG regulation. It should not be so difficult figure out what regulations apply or why. Regulations should make clear what is a major conversion and what isn’t. There should not be so much room for errors in interpretation. Regulations should be clear that, at a minimum, S…

The purpose of 46 CFR 170.170 - Weather criteria seems to be able to differentiate between GM’s for ships trading on the Great Lakes in summer and winter, in exposed and protected areas and on oceans and therefore has to be kept alive… A geographic situation which is uncommon elsewhere.

From the same source a question about the possibility of extrapolating the 50 knot wind and rolling criteria to 80 knots. Sirkar, he knows his stuff, gives the only possible answer and that is that nobody knows and also that there is no such thing as a steady wind under these circumstances. Also IMO…

Here is a link to the testimony above. Hearing 3 day 2 The day before Hearing 3 day 1 - JEFFREY STETTLER, Ph.D. a Ph.D. in the field of naval architecture and marine engineering. - Starts on page135 Following the capsizing and sinking of eight offshore supply vessels in the Gulf of Mexico betwe…

Q. Have you reviewed this trim and stability booklet prior to the testimony today? A. I would not characterize it as a review. I have seen it. I looked at it. Q. Do you know if there’s any GZ curve, minimum required GM. So how is a master supposed to understand all this about GZ and righting arm…

The El Faro was lengthened in 1992-1993 which was ruled a major conversion. SOLAS 90 would have applied as it was effective in 1992. From here: The then renamed International Maritime Organization (IMO) adopted these probabilistic subdivision and damage stability regulations for dry cargo s…

Read for P = .055 (L/1309) 2 metric tons/m 2 in § 170.170: P = 0.055 + (L/1309)² metric tons/m² otherwise you end nowhere with a calculation! As an example with a couple of rough estimates: P = 0.088896 A = 2880 m² H = 10.5 m W = 38490 m³ (Fully loaded, draft = 9.2 m) then the GM = 0.28 m.
