Key Bridge Unified command salvors begin preparing for the removal of bridge section four, which lies across the bow of…
Salvage crews may be getting close to removing the collapsed portion of the Key Bridge in Baltimore that’s resting on that massive cargo ship.
Crews are in the process now of detailing what it will take to raise the section of the bridge that’s on top of the Dali, which caused the bridge to collapse in March after the collision.
The latest information from the team working on the removal is they are meticulously analyzing things like weight shifts, hull damage and obstacles that are in the way.
In addition, special equipment has been brought in to closely monitor the positioning and movement of the ship and the bridge wreckage in contact with it. The equipment figures out how the ship is pitching and rolling with the tide and winds.
“We have a sensor measuring the relative position of the span on the ship so we can see, if for some reason, it starts to slip. We also have what are called string gauges, which can measure, in real-time, the stress, while they are performing operations,” Unified Command contractor Rob Ruthledge said.
The section of bridge on top of the ship is estimated to weigh about 450 tons.
