Early reports said it might be a floating data center, and others said the four-story-tall structure might be a party space.
"'A floating data center' 'A wild party boat' 'A barge housing the last remaining dinosaur'" the spokesperson said in the statement emailed to AFP.
"Sadly, none of the above. Although it's still early days and things may change, we're exploring using the barge as an interactive space where people can learn about new technology."
The barge is located off Treasure Island, an artificial island between San Francisco and Oakland in the San Francisco Bay.
CNET said the barge is 250 feet (76 meters) long, 72 feet (22 meters) wide and 16 feet (4.8 meters) deep.
