RBRglissando

The RBRglissando underway winch enables automated free-fall profiling with instrument payloads up to 20kg. A configurable line speed up to 10m/s allows for operation while steaming normally without slowing down. This fully-automated system is designed for vessels with an existing A-frame or boom, and three-phase power supplies. The compact design is easy to install and occupies minimal deck space. The RBRglissando is controlled by the RBR software, Ruskin, offering wireless downloads after each profile and integration of ship and winch data.

The RBRglissando consists of a drum unit, a sheave unit, and a control cabinet. The stationary drum unit and the control cabinet remain on the vessel or dock, the former bolted or strapped in place and the latter relatively mobile. The sheave unit is mounted above the water. An electric motor turns the drum and provides the lifting force to the winch. The Dyneema^® line unspools from the drum and moves rapidly when launching an instrument. At a rare event of the line becoming entangled during operation, the RBRglissando will trigger an emergency stop. The winch applies an automatic speed throttle at the termination depth and at the surface, and shuts off automatically when the instrument is in the bell mouth.
