Reports earlier this week said it had been awaiting US approval to join the operation in the North Atlantic.
The missing submersible, Titan, which was taking passengers to visit the shipwreck of the Titanic, lost contact on Sunday morning with five people on board.
Oxygen supplies onboard are expected to run out at midday UK time.
Earlier this week Magellan issued a statement saying it is '100% focused on supporting the rescue mission to recover the submersible'.
"We have been working full-time with UK and US agencies to secure the necessary air support to move our specialist equipment and support crew. We are ready to support, and we are fully mobilised to help."
