Salvors appear to be fighting a losing battle to save the X-Press Feeders' containership ablaze off the coast of Sri Lanka.

The owner's representatives said they were still hoping the ship could be salvaged as operations to save it continue.

But latest video images show fire and smoke has engulfed nearly all sections of the 2,743-teu X-Press Pearl (built 2021), after all 25 crew were evacuated, raising concerns it will be a constructive total loss.
