Abstract
Various methods preserve or restore the low roughness throughout an outer shell of a device (e.g., a streamer) used underwater for seismic surveys, by applying various substances that fill micro-cracks, are easy to polish or are self-healing. Apparatuses used to implement these methods may be used shortly before the devices are deployed in water, for example, having the device passing through such an apparatus as it is moved to be deployed in water.
