vessels, Sparrock manages the historic deep-submersible ve- hicle ALVIN; and the Floating Instrument Platform, or FLIP, which are charter-leased to U.S. academic research institu- tions to operate and maintain in support of Navy and U.S. ocean research objectives.

First entering service in 1964, deep diving ALVIN may seem old. But Sparrock said ALVIN has been systematically mod- ernized and upgraded over the years to remain quite youthful.

She has made more than 5,000 dives, and her depth capability has recently been upgraded her 6500-meters. “She’s been re- built so often that it’s not a 60-year-old platform we’re refur- bishing, said Sparrock.

Like Alvin, FLIP is unique. FLIP is also a veteran, entering service in 1962.

FLIP was designed by the naval architecture ? rm Glosten

Associates; built by Gunderson Bros. Engineering Corpora- tion; and has been operated by the Marine Physical Labora- tory of Scripps Institution of Oceanography in San Diego.

The 355-foot FLIP has no means of propulsion, so it must be towed to its working location and either anchored or allowed to drift. By means of a ballasting system, FLIP transitions from the horizontal to the vertical, so the top 55 feet is above the water.

The result is an extremely stable and quiet research platform.

FLIP and her crew of ? ve along with up to 11 scientists could remain at sea for up to 35 days. FLIP had duplicate furnish- ings and ? xtures that could be used in either the horizontal or vertical con? guration.

There are now other ways to perform much of the research

Research Facilities program.

Because there are no funds for major maintenance, FLIP has

Fifty-five feet remain visible after “It would cost about $8 million to make FLIP useable for another ? ve or ten years, but that funding could be better used the crew of the Floating Instrument elsewhere,” said Sparrock.
