Floating Instrument Platform (R/P FLIP) during the "flipping process."
The craft could literally flip from a horizontal to a vertical position while at sea. FLIP was flipped into the vertical position by flooding its long aft section with seawater. Only its “four-story” bow section remained above the water. To return the vessel to a horizontal position, high-pressure air blew the water out of the submerged section.
FLIP was used for studies of wave motion, marine biology, internal waves, sound waves, and other phenomena. The vessel has accommodation for four people and can carry enough supplies to last for about two weeks.
In the vertical position, the research laboratories, living quarters, and engine room were above the water. Two diesel engines supply electrical power for air conditioning and other miscellaneous electrical equipment. Two waterfront tubes permit the crew to descend to 150 feet below the water.
Out of service since August 2023.
