Quoted: God damn. A Chinamax drafts 79 feet. Down by the keel is practically like a submarine at that point. I wonder how thick the hull is down there to resist the pressure. View Quote .433 PSI per vertical foot of immersion for the hull pressure. Hull Plating to the bilge radius is probably 30 to 38 mm thick, and an AH material grade. |

Quoted: Pay attention? Metal starts to move, get the fuck out. View Quote View All Quotes View All Quotes Quoted: Quoted: When dudes are flame cutting the steel members, how do they know that a massive amount of stored energy won’t be released when they complete the cut and unalive their asses? Or do they use expendable/disposable type guys for this type of work? Pay attention? Metal starts to move, get the fuck out. I've done torching. Truck frames, not bridges, but the principles are the same. Torch person works in tandem with the crane operator to cut, lift, and separate the pieces. Building demolition is somewhat the same. |

A channel has opened for vessels clearing wreckage at the Baltimore bridge collapse site The U.S. Coast Guard has opened a temporary, alternate channel for vessels involved in the clearing of debris at the site of the collapsed Francis Scott Key Bridge in Baltimore, part of a phased approach to opening the main channel leading to the vital port, officials said. |

Governor update on Key Bridge collapse
LIVE: Governor provides updates on Key Bridge collapse - wbaltv.com Crews opened a second temporary channel on Tuesday allowing a limited amount of marine traffic to bypass the wreckage of Baltimore's collapsed Francis Scott Key Bridge, which had blocked the vital port's main shipping channel since its destruction one week ago. Work is ongoing to open a third channel that will allow larger vessels to pass through the bottleneck, officials announced at a news conference Tuesday afternoon. The channels are primarily open primarily to vessels that are helping with the cleanup effort, along with some barges and tugs that have been stuck in the Port of Baltimore. A tugboat pushing a fuel barge was the first vessel to use an alternate channel late Monday. It was supplying jet fuel to Delaware's Dover Air Force Base. |

Is it just me, or was that bridge a real asshole design?
It was a like truss bridge and a suspension bridge had too much to drink one night. |

Quoted: @TurkeyLeg Great pic. What does your man do? View Quote Unfortunately, I cant comment on why my guys were there for several reasons. We have customers on all sides of this. Our guys have literally been on every boat in that harbor right now EXCEPT the Dali. It doesnt matter much anyway -- as of right now, there isnt anything worthwhile to report that everyone in the marine industry doesnt already know. I can say this -- the middle of last week it was made very clear to all the marine construction and salvage outfits from Norfolk to Jersey that if cranes and salvage equipment could be provided quickly, they would be paid to be onsite, even if they werent ready for them yet. Seaward out of Norfolk and DonJon up in Jersey beat feet up there last week and are standing by. Crofton sent a crane and the floaters like Dann Marine might be hanging out to get something as well. The companies that do alot of ship docking (Moran, McAllister, etc..) are probably licking their eyebrows right now. Ive already heard rumblings from other municipalities about additional tug assist requirements in the future. Edit to add: Additional tug assists for places that have bridges, I mean. Not really as big a deal for Norfolk due to the CBBT, MMBT and HRBT but there are a few smaller ports that will end up with a huge tug presence before the decade is out. |
