Can a twin engine helicopter be ferried on one engine ?
It depends
If the weight can be sufficiently reduced
If approval from the operator and regulator is obtained
If there is a good reason
Not done it myself but i recall our company moving an S76 single engine in the UK in the late 90's.

or in a tough spot
In EASA-land, if its not a procedure in the AMM or MEL, you'll need approval from your Airworthiness Authority, and they are going to even consider your request without a recommendation from the Type Certificate Holder. Obviously every type (and TCH) is different.
Again, obviously, if the Red-hordes are storming the ramparts you might decide to just do it and sort out the niceties later, but make sure you've got footage of the Red-hordes.

On this side of the pond it can be done legally via a FAA Special Flight Permit (Ferry permit). But on occasion it's been known to be done without said permit especially when a category 4 hurricane is enroute and you're parked on a pad located 2 feet above sea level.
Get a Bell 206LT, or a Gemini ST. Both certified to operate with one or two engines as required.
We had a 212 in Rwanda depart a very unfriendly location on one engine….the start checklist was considerably abbreviated and collective was moving up as throttle was rolled through idle to open. Fortunately they were parked on a hillside with considerable dropdown available. Second engine was started in the air. Nothing like sustained automatic weapons fire to focus the mind. Fortunately just 2 crew and light on fuel.
Been involved a couple of times with 212/412's flown out of not ideal places on one engine , stripped out with min fuel to be flown to a more suitable maintenance place.
Put an uprated PT6 or T-55 Lycoming in one....similar to the Bell 214....with a modern Tail Rotor and you would have a real horse.
I had a engine failure coming off Longships or Wolf rock (brain fart memory) in the Bolkow into Lands End single engine around 1990, where was you’re incident?

I’ve done it in a military Puma from an offshore island back to the mainland.
It required a running takeoff and a running landing but was otherwise uneventful.

Since there is a bit of lamp swinging going on, here's my experience.
Brent Field, far north sea and rig shuttles/bus runs carried out with our Bell 212s in the mid 1970s. Coming in to land on one of the smaller decks one of the PT6 TwinPac decided to have a significant cough,so I landed well off to one side of the (smallish) deck to leave room for a Bo105 to bring in a Ginger Beer or two to have a look. Eventually they turned up and diagnosed a power turbine departure; much discussion and I agreed to S/E ferry it back to our home platform as long as it was defuelled and we had approval from Redhill.
Both requirements ticked off, hassle free flight back.
Except that in the washup it turned out that a small porky had been told, and no approval sought nor given. Lesson learned, trust but verify
