Just in case someone cares for some background information about the A330-2:

ENG: ALL ENG FLAME OUT Checklist
This warning inhibits the EMER ELEC CONFIG warning.
-RAT MAN ON
This confirms RAT extension
-ENG START SEL.................................IGN
This confirms immediate relight attempt.
-THR LEVERS...................................IDLE
-OPTIMUM RELIGHT SPD.......................300/.82
300/.82 is the optimum relight airspeed for wind milling start. One fuelpump remains supplied down to 260 knots.
Note:
  • At 300/.82 with all engines stopped, it takes about 15 minutes to descend from FL400 to the ground. Distance is about 100 NM.
  • In case of speed indication failure (volcanic ash), the pitch attitude for optimum relight speed is -2 degrees (for weights above 150 tonnes add 1/2 degree for each 20 tonnes more).
-EMER ELEC PWR..............................MAN ON Displayed only if the emergency generator is not automatically coupled.
-VHF 1.........................................USE
Only VHF1 is supplied. Notify traffic control of the nature of emergency encountered and state intentions. Transmit a distress message on VHF frequency 121.5 MHz (ATC not supplied).
* IF NO RELIGHT AFTER 30 SEC:
-ENG MASTERS............................OFF 30s/ON
ENG MASTERS must be left OFF for 30 seconds to allow for ventilation of combustion chamber.
*IF UNSUCCESSFUL:
*WHEN BELOW FL 250:
-APU (if operative)..........................START
*WHEN BELOW FL 200:
-WING ANTI ICE.................................OFF
-APU BLEED......................................ON
*IN SEQUENCE
-ENG MASTERS (one at the time)..........OFF 30s/ON
-OPTIMUM SPEED (when APU BLEED available)...230 KT
Green dot speed is not displayed on the captain PFD. Use 230 knots initially before checking in the QRH.
-CREW OXY MASKS (above FL 100)..................ON
-USE RUD WITH CARE
-If forced landing or ditching is expected, use forced landing or ditching procedure in the QRH.
*WHEN BLOW FL 150:
-RAM AIR........................................ON
*EARLY IN APPROACH:
-CAB SECURE..................................ORDER
*FOR SLATS EXTENSION:
-LAND RECOVERY..................................ON
-FOR LDG................................USE FLAP 1
At Flap 1 selection, the emergency generator stops.
-MIN RAT SPEED..............................140 KT
F/CTL servos are supplied be the RAT down to 130 knots.
*FOR LDG GRAVITY EXTENSION:
MAX SPEED...................................200 KT
-L/G GRVTY EXT (if no ditching expected)......DOWN
Disregrad "USE MAN PITCH TRIM" on PFD since the stabilizer control is lost.
*WHEN L/G DONWLOCKED:
-L/G DOWN TARGET SPEED.......................170KT
*AT TOUCH DOWN:
-ENG MASTERS...................................OFF
-APU MASTER SW.................................OFF
-EVACUATION...............................INITIATE
HYD B+Y SYS LO PR
-AFFECTED PUMPS................................OFF
MANEUVER WITH CARE
F/CTL ALTN LAW (PROT LOST)
SPD BRK.................................DO NOT USE
MAX SPEED..................................330/.82

plus STATUS ...

(I'm aware that a relight wasn't an option here, just wanted to offer the whole checklist.)

The ENG SHUT DOWN checklist does NOT ask for an opening of the FUEL X-FEED, as the A32x ECAM does, but requests to MONITOR the FUEL IMBALANCE. Therefore chances are lower to empty all tanks via the X-FEED by mistake. (I don't want to insinuate anything here!)

The FUEL LEAK checklist only allows the X-FEED to be opened, if the leak is confirmed to be within the engine and it is shut down. In all other cases (wing leak, unknown leak) the X-FEED must be remained closed.
Besides : Even with a fuel imbalance of one wing full / one wing empty, there is no special procedure required for approach and landing.

The A330 wingtanks consist of an outer tank and an inner tank. Each inner tank is divided into two parts via a SPLIT valve that normally remains open. The inner tank is used as a single tank and if tank damage is suspected (i.e.
FuelQuantityIndication data is lost or there is a rapid FQI decrease following an engine failure), the SPLIT valve can be manually closed by using the dedicated pushbutton. The ENG FAIL checklist with assumed damage to the eng. asks for that step.
This isolates 1150 kg fuel from the remaining innertank. The two main fuel pumps for each engine are located within this splitted tank section.
A GW of 170T results in a engine out FL of ~FL200. FF is approx 6500kg.
A GW of 210T results in a engine out FL of ~FL180. FF is approx 7400kg.
