The 20000TEU Ever Given lost power and wedged itself into the bank of the Suez Canal, blocking traffic in both directions. The Suez Canal saves about 12 days sailing time around Africa, so right now shipping lines are likely trying to decide if its better to wait or divert, knowing their schedules are now going to be thrown out of whack by the closure.
There look to be about 8 tugs on scene, and there is an excavator digging sand at the bow. Below is a photo and narrative for a crew member on the US Flagged Maersk Denver.
Several Halifax Services including the Oceans Alliance (CMA-CGM) and The Alliance (Hapag-Lloyd) rely on routing through the SUEZ Canal
UPDATE – ships managers are claiming all machinery was in working order, so the reason for the grounding is unclear. The ship is still stuck
