I have not come across any others - Halliburton actually builds ports, but does not run any - definitely none I know of that can take over 7 U.S. ports on March 2nd.
What would a company have to have by way of $ value to undertake this contract? $2 billion? That's how it works in business, in the oil pipeline business for example. The TransAlaska Natural Gas Pipeline contract required the successful bidder to have an interest, either ownership of proven gas reserves or company capital, of several $ billion just to bid.
