A valve nozzle assembly including a number of valve nozzles arranged in a predetermined pattern. Each valve nozzle may include at least one coil; and a magnet adapted to be movable between a closed position closing the nozzle and an open position opening the nozzle, wherein a movement of the magnet between the closed and the open position is controllable by a magnetic field from the at least one coil.

A streamer cleaning device includes a plurality of cleaning modules affixed to a main frame in angularly spaced apart orientation. At least one cleaning module includes a drive wheel rotationally coupled to a cleaning element. At least one cleaning module includes a guide mounted thereon. The guide is configured to deflect devices mounted on the streamer out of a path traversed by the cleaning modules. At least one of the cleaning modules comprises a device for conversion of motion of water past the at least one cleaning module into rotational energy to drive the drive wheel thereon.

A cleaning device for a seismic streamer includes a housing placeable the exterior of the streamer. A turbine is associated with the housing and is configured to be rotationally driven by movement of the streamer through a body of water. A drive element is associated with the housing and is configured to convert rotational motion of the turbine to motive power to move the housing along the streamer. At least one cleaning element is associated with the housing and is cooperatively engaged with the exterior of the seismic streamer. A method for cleaning a streamer includes towing the streamer through the water. Motion of water is converted into motive power to move a cleaning device along the streamer.
