The magic number is the 8+ kts speed. I'm sure there is a minimum steerage speed for that ship, maybe 4-4.5 knts. The ship should be restricted to steerage in those waters accompanied by 2 tugboats, And that I'm sure will be enforced when the bridge is cleared and during construction of the new. Keep in mind the ship's agents pay the tug boat fee and try to save so long as they operate in the rules of the harbor. And that's the key. Here in RI in the Providence harbor basin they receive tankers and freighters in the 700 ft range, piloted at the beginning of Narragansett Bay, about 12 miles from the basin. They are received by 1 tug at the beginning of the basin, and escorted out of the basin by a tug. They have 1 bridge to cross under, Narragansett Bay bridge and there is now serious talk among the pilots to have tug escort. Keep in mind there are no behemoths entering Narragansett Bay comparable to this monster. To me, having monsters like this operating at 8+ knots speed in restricted waters is asking for disaster. And that's exactly what they have.
