A second tanker, the very large crude carrier Pantanassa, is navigating towards Venezuela and expected to load later this month 2 million barrels of the same grade, diluted crude oil (DCO), also bound for Europe, with an option to sell a portion of the cargo to Spain's Repsol, according to a shipping document and sources.

Eni and Repsol did not immediately reply to a request for comment.
