ABSTRACT:
A handling system for lowering and retrieving large and heavy objects such as sonar arrays from surface ships and other unstable platforms. A submersible object which normally is suspended by a single cable when at operating depth is retrieved and returned to a surface platform by a messenger device suspended on two or more other cables from the platform and provided with means for guiding the messenger to the object, orienting the object with respect to the messenger and thus with respect to the surface platform, and locking the messenger and object together. The resulting messenger and object assembly then may be hoisted back to the platform with some or all of the weight of the assembly carried by the messenger cables thus at least partially unloading the main support cable during retrieval.
