just a nice report
Summary
On 15 December 2011, at 0910 Eastern Standard Time, the bulk carrier Orsula departed Contrecœur, Quebec, in ballast for Baie-Comeau, Quebec. While proceeding downbound on the St. Lawrence River under the conduct of a pilot, the vessel lost steering control and ran aground at 1329 on the Battures de Gentilly, 1.25 miles northeast of Bécancour wharf, Quebec. About 48 hours later, it was refloated on the first attempt using tugs. The vessel sustained hull damage, which required repairs. There were no injuries or pollution as a result of this occurrence.
Steering gear
The Orsula is equipped with an electro-hydraulic Rapson Slide (type FM21-072) steering gear with 2 rams and 4 cylinders, manufactured by Kawasaki-Wuhan. The hydraulic cylinders are supplied by 2 variable-delivery main steering gear pumps operated through a floating lever arrangement driven by a set of 2 telemotor receivers. Only 1 telemotor receiver can be used at a time, but it can drive either 1 or 2 variable-delivery main steering pumps at the same time.
In case of failure of all remote steering gear control systems, it is possible, as an emergency measure, to detach the 2 telemotor receivers from the floating lever arrangement and connect a hand trick wheelFootnote 9 to directly and manually operate the variable-delivery main steering pump. However, in order to do this, an operator must be situated locally in the steering gear compartment to operate the trick wheel and follow orders given by bridge personnel through a communication device.
(see full report - the pilot was unable or too distracted to make use of the feature mentioned above)
Reversing the main engine
The vessel is fitted with a direct-drive reversible low-speed engine. The engine drives 1 fixed-pitch propeller, and the vessel service speed is approximately 15 knots.

stern means rear of ship, as in reverse
*****
The bridge control of the engine enables a crew member to start the engine ahead or astern and choose different speed settings. To switch from ahead to astern movement, the engine must be allowed to slow down to a designated revolution (37 rpm) to prevent excessive stresses and forces before it can then be set into reverse mode and restarted astern.
When the main engine is set to full ahead (127 rpm) and the vessel speed is 14.8 knots, it takes 155 seconds for the engine to set into astern starting mode. As well, in the case of an emergency stop (putting the telegraph from full ahead to full astern), the vessel can be stopped in 5 minutes and 21 seconds.Footnote 11 This information was posted on a bulkhead in the wheelhouse.
-----------------------------------
so for a BRIDGE SITUATION, THIS MEANS, that any navigation which would be 6 minutes out would be "very aware and slow down for bridge"
it also means a vessel 2 minutes out could not even apply reverse engines in time to even begin slowing speed, per say, once again demanding a large vessel "take it slow near a bridge" (which already is in navigation law anyhow!)
