HDW departed Halifax for OP Nanook on August 15th, seems repairs are complete.
To true. the first of any class of warship tends to suck I’m actually proud of our naval engineers for finding these problems in that they find problems down here instead in the Arctic.
Back to Halifax for HDW after only a few days at sea from her last repair. Not exactly a huge confidence booster for such a relatively new vessel on the inaugural two ship Arctic deployment of the class.

Still had 3/4 of the DG’s left.Know not if that is important.
HMCS Harry DeWolf diverts to Halifax due to failure en route to Arctic mission | Globalnews.ca
A diesel generator failure has forced HMCS Harry DeWolf to divert back to Halifax while en route to join a two-month, multinational mission to the Arctic.globalnews.ca
EDIT: didn't even notice that stuff had been posted already.

One figures the damage to the 1 had to be really significant to divert - or concern it may cascade.
These DAs are quite large and certain parts are not typicially carried. There are many factors to consider when making a decision to return. It could be as simple as how hard it would be to get technical staff and parts in for repairs in the Arctic which is not easy. It also could be what is the min safe to sea state the ship could be in before it would have to go along side. We have a document called the material baseline standard that dictates what is the min technical state we need to be at before going to sea or remaining at sea safely.Still had 3/4 of the DG’s left.

I thought they had ALCOs driving generators, powering main electric motors driving the shafts? Isn’t that like the AOPS setup?Don't know what you refer to about the CCG R-boats. They didn't have electrical propulsion, they had diesel driven twin screws.
All 4 DGs provide propulsion. As you need more power you bring on another DG. At sea you always have a min one DG online. Each DG has a 450V Alternator that provides hotel load. As back up you have one emergency DG.I’m tracking correctly that these DGs are propulsion, not smaller ones for hotel power, right? Like the CCG R-Class?
Sorry OGBD, I meant Raddison class. CCG site interchangeably uses ‘Medium Icebreaker’ and Raddison/R Class.Well, I drove Rally when she was in the reserve fleet, and my recolection is twin diesel driving screws. Maybe Colin can correct me if I am wrong.
Maybe you have a different R-class in mind. These were dinky toy little 95 footers used as SAR cutters with pretty small engine compartment. Diesel electric drives would have been pretty complex things to put in such small vessels. Besides, I distinctly remember that we had to "click" the throttles in at the lowest setting and wait a second or two for the screws to engage before we could slowly ramp up the RPMs, which to me is indicative of a fixed pitch screws on diesel driven shafts - not electric motors.
Perhaps it is the MCDVs you have in mind. They are diesel electric ships set up the same way as the AOPS (or rather, the AOPS are set up like the MCDVs because "chicken and egg").
