Baltimore media, including WBAL TV, report that eight members of the crew of the containership Dali are set to return to their homes in India and Sri Lanka. The way for their departure was opened after attorneys for the City of Baltimore dropped a petition seeking keep the crew in the U.S. after receiving commitments from Dali owner, Grace Ocean Private Limited, and manager, Synergy Marine, to respond to a request for interviews within 30 days and to guarantee crew members will appear.

Charleston Harbor Pilots avert potential box ship strike on bridge

The skill of Charleston Harbor Pilots may well have saved the Arthur Ravenel Jr. Bridge over the Cooper River from potentially suffering the same sort of fate as Baltimore’s Key Bridge.

The incident began yesterday when Coast Guard Sector Charleston command center watchstanders received a report at 12:17 p.m. from the Charleston Harbor Pilots dispatch of a containership, the MSC Michigan VII, experiencing a malfunction with the systems controlling its propulsion on the Cooper River while...

VIDEO: Last large Key Bridge section moved from Federal Channel

Ten weeks after the containership Dali struck Baltimore’s Francis Scott Key Bridge initiating its collapse, salvage crews successfully removed the final large steel truss segment of the bridge blocking the 700-foot-wide Fort McHenry Federal Channel on June 3-4.

Using concrete breakers, underwater surveys, and oxyacetylene torches, they separated tons of concrete roadway, cable, and steel rebar from “Section 4C” while removing debris with clamshell dredges.

On May 20, Unified Command had cleared...

How they planned to get Dali refloated and relocated

The Key Bridge Response Unified Command reports that salvors refloated and moved the M/V Dali at approximately 7 a.m., this morning. Video streamed by local media showed the Dali refloated, under tow and then alongside at the Port of Baltimore’s Dundalk Marine terminal, still with a portion of highway across its bow.

The whole operation appears to have gone completely according to a plan details of which were released Saturday.

That plan said that optimum conditions called for the transit of the...

NTSB: Dali had two blackouts on day before bridge strike

Image from NTSB preliminary report helps explain blackouts

Even as efforts continue to remove the containership Dali from beneath the remnants of Baltimore’s Francis Scott Key Bridge, an NTSB preliminary report has been released that says that the Dali lost power twice before slamming into the bridge.

Two other things that emerge is that all drug and alcohol tests were negative and that fuel tests revealed no fuel contamination.

What happened with the power blackouts — and in particular the two experienced while the ship was in port? If you’re unfamiliar...

VIDEO: Explosive cuts part demolish Key Bridge

Using precision explosive cuts, the Key Bridge Unified Command today demolished part of the Francis Scott Key Bridge that had been pinning down the bow of the Dali, the containership whose strike on the bridge initiated its collapse. Videos posted on YouTube and on C-Span, show that the demolition did not proceed exactly as originally planned.

Initially, the plan had been to demolish the whole of the bridge section resting atop the Dali.
