Floating authorities visited the floating mystery barge moored to Treasure Island -- and obeyed a secrecy order imposed by the people behind the secret project on the imposing structure, which by all accounts is Web giant Google.
The four-story floating structure may be a data center, a store for Google Glass, or some other "top secret" project, as many outlets have reported over the last week.

However, "top secret" is all the Coast Guard will say the barge is, as the agency has "been ordered to remain tight-lipped," according to the San Jose Mercury News.
The Coast Guard visited the barge this week, for unknown and unspecified reasons.
A company called By and Large, which has ties to Google, owns the barge, and lawyers for Google asked for permits for such a structure "months ago," according to the newspaper.
A nondisclosure agreement was signed by the Coast Guard, Reuters reported -- but another Coast Guard spokesman was so reticent he could not even confirm that, the Mercury News reported.

Only when "the project is completed" can the public agency release information, a Coast Guard spokesman said.
As for when that will be? No loose lips aboard this ship, so it's anyone's guess -- or Google's, mostly.
