浮式仪器平台（英语：FLoating Instrument Platform，缩写：FLIP），或称浮动观测平台、浮动仪表台、浮式仪器平台、腐观测平台、腐水文观察平台、水下声波探测船、浮动水文观察平台、浮动仪表工作台，是一艘由海军研究办公室拥有，圣地牙哥加利福尼亚大学斯克里普斯海洋学研究所海洋物理实验室操作的海洋研究船。此船是一艘长355英尺（108米）的船只，且船身被设计成能够与水面形成直角。

R/P FLIP (FLoating Instrument Platform) is an open ocean research platform owned by the U.S. Office of Naval Research (ONR) and operated by Scripps Institution of Oceanography. The platform is 108 meters (355 ft) long and is designed to partially flood and pitch backward 90°, resulting in only the front 17 meters (55 ft) of the platform pointing up out of the water, with bulkheads becoming decks. When flipped, most of the buoyancy for the platform is provided by water at depths below the influence of surface waves, hence FLIP is stable and mostly immune to wave action similar to a spar buoy. At the end of a mission, compressed air is pumped into the ballast tanks in the flooded section and the platform, which has no propulsion, returns to its horizontal position so it can be towed to a new location. The platform is frequently mistaken for a capsized ocean transport ship.
