A supertanker adapted to scoop up oil from the BP spill in the Gulf of Mexico began tests on Saturday amid a report that some major investors expect the energy giant to replace its top executives.

The vessel named “A Whale” and dubbed a “super skimmer” is operating just north of the blown out well as part of a two-day test watched by the U.S. Coastguard, said Bob Grantham, spokesman for TMT Shipping Offshore, which owns the ship.

If all goes to plan TMT hopes to sign a clean-up contract for the ship, which can remove up to 500,000 barrels (21 million gallons) of oil and water mix from the sea surface a day, according to crew members.
