Not according to Denholm(?) shipping, on radio 4 this AM, getting cranes that can reach 200'(?) to the site etc., will take a week or so.
What are they hoping to lift? Supplies?

Main engine is nearly 80,000 hp, and the bow thrusters 3,400 hp each.

With a little creativity, she could be off in no time:

Empty barge alongside the starboard hull towards the bow as a fulcrum.
A couple of tugs on the port bow lines, one forward and one aft.
Starboard stern lines to the eastern bank and anchored.
Both bow thrusters to push the bow out, Main engine full astern at the same time.

Might not be pretty, but it would get it done.

As I understand it these ships run almost fully loaded and so with minimal ballast - and just enough bunkerage to get to the planned destination so as to navigate the canal with the greatest profit.

The canal tugs have very limited pull/push ability and salvage tugs they most certainly are not.

Think landy defender with a winch on the back versus a full blown truck recovery vehicle....   ;D

It was actually lost of propulsion power (these ships have the usual big engine driving the prop plus a set of other independent gen sets for hotel load and tunnel thrusters).

Throw in a cross wind and the fact that rudders are far from great without a prop running.....and you lose control.

This won't be reliable enough....Something Japanese may be required. ;) :D

Almost mr DTM.  Generator/Alternator setup also will be providing power for lube pumps, coolant pumps, lighting in the engine space as well as the hotel side of air on, fridges, fresh water circ etc.  A power blackout shuts down the entire vessel and if emergency systems donít auto start quickly and the crew not quick to light the engine again, then it ends in tears.

Their biggest asset has to be the power of the ship itself. It only needs to move enough to free the bow... once that happens, she can be set along side more 'conventionally'.

QED :y

I suppose the real question then is: can propulsion be restored before a bloke and a bobcat can dig it out? The bow thrusters alone ought to be enough to shift the bow and/or the material it's sat on.

Not on these, the prime is shaft drive only and has no generation, the electrical is a DP2 so primary support systems run with loss of an electrical engine room, this includes diverse feeds to sub systems, switchboards the works. They are specifically designed such that a SPOF will not impact life support for the primary  :y

Sadly not, the tunnels will only be of the order of a few MW, never shift.

The only hope is dig the bow out, lose some weight, get a high tide and tug like hell

I'm quite happy to offer a 'push' if it will help.... ::)

Do keep up Mick!  :)

We live in a giant prison camp now as it's illegal to leave the country.  :(  ::)

I doubt there are even dispensations for OOF experts!  ;D
